Dear David:
As a graduate of UC Berkeley and UC Davis, I know UCSC very well. I got
into entomology after reading Rachel Carson's Silent Spring at UC Davis.
After working on cotton insects and studying with Hoy, van den Bosch and
others in California in the late 1970s, I went to Mississippi full of
missionary zeal to reduce their insecticide use on cotton and quickly
learned that 50-75% of it really was necessary. I also initially opposed BT
cotton thinking it would cause resistance too quickly. My own research
convinced me otherwise. (see Roush, R. T. 1998. Philosophical Transactions
of the Royal Society of London, Series B, 353, 1777-1786 and papers cited
therein.)
Actually seeing the impact of Bt cotton in the field also changed my mind;
it was far more effective in reducing insecticide use than anything we ever
dreamed of. Agroecology did not save the lives of 3 kids poisoned by a
cotton insecticide when I lived in Mississippi. A few years ago, more than
400 people per year died in China from exposure to cotton insecticides. Bt
cotton has reduced insecticide use by 75%, in a country that could teach
UCSC about agroecology.
For some of this work, see Pray, C. E., D. Ma, J. Huang and F. Qiao
(2000): "Impact of Bt-cotton in China." World Development 29(5): 813-825.
Agroecology will not solve the problem of fumonisins in corn. In fact, I
initially opposed EPA on registration of BT corn in a very widely
distributed letter in 1996. What changed my mind was data on fumonisins.
Fusarium ear rot is the most common ear rot disease in corn, increased by
damage to corn kernals by insect attack. The primary importance of this
disease is its association with mycotoxins, particularly the fumonisins.
Fumonisins are a group of mycotoxins that can be fatal to horses and pigs,
and are probable human carcinogens. They are a leading cause of throat
cancer in east Africa and possibly South America. Results of field studies
have consistently demonstrated that Bt corn hybrids experience
significantly lower incidence and severity of Fusarium ear rot and yield
corn with lower fumonisin concentrations than their non-Bt counterparts.

There are alternative views to this of course, the biologist Ghiselin for
instance argued that there was in fact one 'economy' of two components: a
natural economy (i.e. biological systems) and a political economy. The
connections between both are sufficently developed that changes in either
system can exert profound effects on the other.

In contrast, Alfred Marshall in his "Principles of Economics' (first
published in the late 19th C) wrote
"But economics has no near kinship with any physical science...it is a
branch of biology broadly interpreted".
Marshall was the 'founder' of neoclassical economics- the predominant
'school' in most university economics departments.

Charles,
The newer terminology I've seen and used is Jaccard's =3D a/(a+b+c) and
S=F8rensen's =3D 2a/(2a+b+c), where a =3D # of species present in both
samples, b =3D # of species present in sample 1 but not sample 2 and c
=3D # of species present in sample 2 but not sample 1. Some of the
older terminology used symbols for total # of species in each sample,
which led to some of the expressions you have used.
I've been spending a lot of time recently examining similarity
indices, since I've been working on fuzzy set ordination, which
requires similarity indices. I've found that both Jaccard's and
S=F8rensen's are very good indices for this purpose; my results are
reported (horn tooting mode on) in a forthcoming paper in Journal of
Vegetation Science (horn tooting mode off). Other indices that work
well for presence-absence data are Baroni-Urbani & Buser, Kulczyinski
and Ochiai.
So I hope that similarity indices will be used more as others see the
utility of fuzzy set ordination (and perhaps its older uncontrained
cousin, polar (Bray-Curtis) ordination). I do know that indices are
used for cluster analysis. Hope that is helpful.

Lynn and Dave,
Here is a good example of the danger of extrapolating from one disciplin
to
another. You should use the covariance matrix. The reason for doing so is th
t
it
preserves the units of measurement, which are what you need to plug your
results back into quantitative genetics and response to selection equations.
Because all of your data are in the same units (percentages), covariances an
correlations should give you very similar results.

http://www.eurekalert.org/pub_releases/2001-10/uoc--iad101001.php
Invading ants disrupt ecosystem
The tiny black Argentine ant is well known as a household pest. But by
replacing native ants, they could also be disrupting natural ecosystems.
A study by a University of California, Davis, graduate student,
published this week in the journal Nature, has for the first time shown
that when key beneficial species are removed by an invader, the
destructive effects can reverberate through the ecosystem.
Caroline Christian, a student at the UC Davis Center for Population
Biology, studied the fynbos shrublands of South Africa, an area similar
in climate and vegetation to the chaparral of California. The fynbos is
renowned worldwide for its high level of biodiversity. Wildfires sweep
the fynbos every 15 to 30 years, killing most mature plants. New plants
grow from seeds buried in the ground by native ants. Christian found
that when Argentine ants displace native ants, plants that depend on
those ants to bury their seeds do not regenerate after fire.
"There's been a lot of concern that invasive species may disrupt
mutually beneficial interactions between plants and animals," said
Maureen Stanton, a professor of evolution and ecology at UC Davis and
Christian's thesis supervisor. If those interactions are crucial, there
might be cascading effects on the whole community, she said.
Seed burial by ants is key to survival for about a third of fynbos plant
species, Christian said. When fresh seeds fall, ants are attracted to
them and carry them off to bury in their nests. Different ant species
specialize in seeds of different sizes: Ants that work cooperatively
deal with bigger seeds, while ants that tend to work alone bury smaller
ones. If the seeds are not picked up quickly, virtually all are eaten by
rodents.
Argentine ants do not bury seeds at all. But they do wipe out two fynbos
ant species, Anoplolepis custodiens and Pheidole capensis. Two others,
Meranoplus peringuey and Tetramorium quadrispinosum, coexist with the
invader. It turns out that Anoplolepis and Pheidole ants prefer large
seeds, while the others go for small seeds.
Large seeds placed in invaded areas were less likely to be buried by
ants and more likely to be eaten by rodents, compared to large seeds in
uninvaded areas, Christian said. Small seeds were much less affected.
Christian carried out controlled burns of areas in fynbos to see whether
the invading ants had a real effect on the plant community. Seeds of
many fynbos plants need fire to germinate, so most new growth happens in
the year after a fire.
After burning, invaded areas showed a tenfold drop in the number of new
plants from large-seeded species, compared to uninvaded areas, Christian
said.
"It's sobering, and a wake-up call," said Stanton. The study showed the
threat from invasive species both to the fynbos and to ecosystems in
general, she said.
"This is the first work to show not just the immediate effects of an
invasive species, but the larger effects on an ecosystem," Stanton said.
Potentially, there could be further effects. For example, animals that
eat large-seeded fynbos plants may also decline as a result of the
Argentine ant invasion, she said.

The study was funded by the National Science Foundation and conducted in
Kogelberg Biosphere Reserve, South Africa, with assistance from the
South African Museum and Cape Nature Conservation. It is published in
the Oct. 11 issue of Nature.

http://www.eurekalert.org/pub_releases/2001-10/uow-acc100501.php
Accumulated change courts ecosystem catastrophe
MADISON - Subjected to decades of gradual change by humans, many of the
world's natural ecosystems - from coral reefs and tropical forests to
northern lakes and forests - appear susceptible to sudden catastrophic
ecological change, an international consortium of scientists reports
today, Oct. 11, in the journal Nature.
"Models have predicted this, but only in recent years has enough
evidence accumulated to tell us that resilience of many important
ecosystems has become undermined to the point that even the slightest
disturbance can make them collapse," says Marten Scheffer, an ecologist
at the University of Wageningen in the Netherlands and the lead author
of the Nature paper.
Indeed, as scientists have come to assess change over time and over
entire ecological regimes, a gradual awareness is building in the
scientific community that stressed ecosystems, given the right nudge,
are capable of slipping rapidly from a seemingly steady state to
something entirely different, says Stephen Carpenter a limnologist at
the University of Wisconsin-Madison and a co-author of the paper.
"We realize that there is a common pattern we're seeing in ecosystems
around the world," says Carpenter, an authority on lakes. "Gradual
changes in vulnerability accumulate and eventually you get a shock to
the system - a flood or a drought - and, boom, you're over into another
regime. It becomes a self-sustaining collapse."
Carpenter is one of five authors of the paper whose contributors include
experts on an array of the world's different types of ecosystems.
The recognition that many of the world's ecosystems engage in a delicate
balancing act has emerged as science has become more adept at assessing
entire ecological systems and by a better understanding of how
catastrophic ecological change has occurred in the past.
For example, 6,000 years ago, swaths of what is now the Sahara Desert
were wet, featuring lakes and swamps that teemed with crocodiles, hippos
and fish.
"The lines of geologic evidence and evidence from computer models shows
that it suddenly went from a pretty wet place to a pretty dry place,"
says Jonathan Foley, a UW-Madison climatologist who is also a co-author
of the Nature paper. "Nature isn't linear. Sometimes you can push on a
system and push on a system and, finally, you have the straw that breaks
the camel's back."
Most ecosystems, the authors write, face a steady diet of change,
whether it be from increased nutrient levels or a ratcheting up of human
exploitation. Moreover, anticipated changes in global climate are
expected to add to what now seems to be a far more precarious situation
than scientists had previously imagined.
"All of this is set up by the growing susceptibility of ecosystems,"
Carpenter says. "A shock that formerly would not have knocked a system
into another state now has the potential to do so. In fact, it's pretty
easy."
As an example, Carpenter cited Madison's Lake Mendota, an urban lake
that is perhaps the most studied lake in the world. It has seen a steady
influx of nutrients - chemical runoff from farms and suburban lawns - as
the land around it has been chemically enriched and then developed over
time.
"Over the past 150 years, we've put a huge amount of phosphorus into the
mud of Lake Mendota and it's prompted a lot of algae growth" in a lake
that was once very clear. In 1993, scientists watched nutrient levels
grow sharply after a single heavy-rain event washed more nutrients into
the lake. "This phosphorus buildup has made it easy for Lake Mendota to
go into a eutrophic state" characterized by green surface scums.
"Reversing eutrophication is hard because of the buildup of phosphorus
in soils and sediments," Carpenter says.
Similar patterns of ecosystem degradation are evident on coral reefs and
in forests. If large enough, forests can influence the weather, or even
have their own weather systems by facilitating the movement of water
from the surface of the earth to the atmosphere. Overexploitation of
those forest resources, says Foley and Carpenter, can have profound
effects beyond the simple extraction of a resource such as wood.
"The idea that nature can suddenly flip from one kind of condition to
another is sobering," says Foley, who suggested that changes can be
irreversible. "For hundreds of years, we've been taught to think in very
linear ways; we like to think of nature as being simple. But now we know
that we can't count on ecosystems to act in nice simple ways."
The implications of losing ecosystem resilience, according to the
paper's authors, are "profound" in light of current resource management.
"Regime shifts," they wrote, "can imply a drastic loss of biodiversity
as well as utility for humans."
Moreover, while subtle change over long periods of time undermines
ecosystem resilience, it "implies a lack of early warning signals." And
since a single event - a flood or a drought - can cause an ecosystem to
shift from one state to another, "the role of gradual environmental
change might be disputed."
Carpenter sees two management messages: "One, you can't see the change
unless you have a view of the entire ecosystem over a long period of
time and, two, there are slowly changing variables" that can lay a
foundation for catastrophic change.
Understanding the forces that drive the machinery of ecosystems is
really a key to their protection, says Scheffer. "Once you understand
the picture, you can sometimes find ways to flip ecosystems back to a
desired state. For instance, we have shifted lakes into a clear state by
manipulating fish populations, and we are exploring the possibility of
using El Ni=F1o episodes as windows of opportunity to restore degraded
arid ecosystems."
Says Carpenter: "Although it's possible to push things in the other
direction, to a certain extent, restoring a system depends on the art of
the possible. What can you do within the constraints of politics and
economics to turn back the tide?"

CRAYFISH IN SAM HOUSTON NATIONAL FOREST ILLUSTRATE ENVIRONMENTAL HEALTH
Writer: Kathleen Phillips, (979) 845-2872,ka-phillips@tamu.edu
Contact: Dr. Fran Gelwick, (979) 845-5777,fgelwick@tamu.edu
COLLEGE STATION - Crayfish boils may be the delicacy of choice at some
Southern dinner parties, but environmental studies indicate there's
something else cooking in the lobster-like crustacean's future.
And understanding the ecological recipe may help researchers predict the
health of our nation's streams.
Of the nearly 340 species of crayfish in North America, more than half
are suffering in some way: 65 are endangered, 45 are threatened and 50
are of "special concern," or on watch for changes in their populations.
At least one researcher at Texas A&M University has set out to
understand why, but she's not just looking at the animal itself.
"I'm a community ecologist," said Dr. Fran Gelwick, wildlife and
fisheries biologist. "I look at everything that pertains to the health
of the environment in which an animal lives. By understanding how
organisms influence their environment, as well as how environmental
changes affect the organisms, we can monitor for symptoms of adverse
conditions."
The findings of Gelwick and graduate student Brian Healy, presented at
the recent North American Benthological Society meeting, detailed how
crayfish cope with the challenges of weather, predators and human
intervention, for example.
"The various species have different strategies, in the evolutionary
sense, of dealing with situations," Gelwick said. "Each has their own
strength and weakness, but those with the better match to the river
system are more likely to sustain their population."
The decline of certain species of crayfish is not unlike that of other
wildlife, Gelwick said. Many species of crayfish have a limited natural
range (they can't travel too far from water), their habitat is being
lost to urban encroachment, and chemical runoff has polluted many water
systems.
Yet crayfish play an important role in streams. They eat small fish and
insects, process debris and are prey themselves for larger fish and
people. These roles are important in maintaining healthy ecosystems,
Gelwick said.
"They process large pieces of organic matter," she said. "My idea of
dirt might be another animal's idea of food. The crayfish take large
leaves, algae or dead animals in a stream and process it into smaller
pieces that then can be used by the smaller animals in the ecosystem.
You can think of them as a conveyor belt through which a product goes in
one way and comes out another that is more useful to the next consumer
in the food web."
Crayfish also could be thought of as residential developers - living in
self-dug burrows for a while before digging a new place.
"Some animals actually live with crayfish and others use the old burrow
left behind," she noted.
For the study, Gelwick and Healy pegged the headwaters of the San
Jacinto River, an 85-mile body of water that courses through the Sam
Houston National Forest, from Walker County southeast, until pouring
into the Gulf of Mexico at Galveston.
They looked at how environmental factors in streams with different flow
regimes related to crayfish distribution and, how the crayfish species
present fared in response to environmental conditions, such as drought
and amongst their competitors and predators.
More than 100 observations were made in pools and runs along the river
through the forest. The streams were measured for water speed and depth.
The effects of other variables, such as water quality, frequency of
drought and abundance of predatory fish, were compared to the abundance
and body size of each crayfish species during the four seasons of one
year. Their findings indicate that drought hammers some kinds of
crayfish, predators grab others, while one - Procambarus clarkii - is a
generalist who can tolerate such pressures for a better chance of
survival, mainly because it not only digs burrows but also can spawn
repeatedly during a season.
Here are some factors about the species they observed:
* P. clarkii population - not currently threatened or endangered.
* Orconectes palmeri - not currently threatened or endangered; appears
to move, rather than burrow during drought; has larger "pincers" and
body size which make it a good competitor and help it avoid predators.
* Procambarus kensleyi - currently is considered of special concern by
the Endangered Species Committee of the American Fisheries Society.
Gelwick and Healy found its ability to burrow likely makes it more
tolerant of drought, but due to its smaller size, it is apparently less
competitive with other crayfishes and more susceptible to predators.
Gelwick has been involved with biodiversity research along the Trinity
and San Jacinto rivers for about six years in cooperation with the Texas
Parks and Wildlife Department, the U.S. Forest Service, and the U.S.
Forest Service, which have funded many of her studies.
"We've built up a nice database from the San Jacinto River drainage
basin, and those who manage natural and human systems have started
talking to each other," Gelwick said. "Together we can help people enjoy
their natural resources, while preserving them for generations yet to
come"

Subject: stopping logging in high conservation value forests - new report
Industrial logging threatens many of the world's most biologically rich =
forests. A concerted effort to halt or prevent logging in forests with the =
greatest value for conserving biodiversity is urgently needed. In support =
of this effort, The Union of Concerned Scientists and the Smithsonian's =
Center for Tropical Forest Science are pleased to announce the release of =
a new report, Logging Off: Mechanisms to Stop or Prevent Industrial =
Logging in Forests of High Conservation Value. Authored by Ted Gullison, =
Mary Melnyk, and Carmen Wong, the report provides the broad assessment of =
the potential tools available to reduce or eliminate industrial logging in =
high conservation value forests. The authors review a series of case =
studies of different approaches that have already been applied in tropical =
and temperate forests and identify 15 different mechanisms through which =
logging could be stopped or prevented. These range from purchasing timber =
concessions for protection and cracking down on illegal logging to =
international timber boycotts and import bans. Several mechanisms have =
been successfully implemented, and some, such as conservation easements, =
have been applied in a number of countries for decades.=20
The report concludes with recommendations for actions that policymakers, =

Penn State University in University Park, PA. The specific research
objective is to quantify the contribution of plant species diversity to
grazed ecosystem productivity, resilience, and persistence by: 1)
determining how biodiversity in grazing lands affects productivity at
multiple scales, 2) quantifying spatial variability in plant populations
and communities in grazed ecosystems, and 3) integrating the information
into appropriate models. Research is predominantly field-based and will be
conducted at multiple scales and will require innovative experimental
designs and approaches to determine how spatial variability and landscape
factors affect ecosystem processes. The research will be conducted
collaboratively as part of an interdisciplinary team researching the
effects of grazing systems on biodiversity, nutrient cycling, productivity,
and hydrology of farms and landscapes. A Ph.D. or equivalent in plant
ecology, botany, or a closely related field is desired. Candidates must

This is an important piece of research, but I'd like to clarify one point.
Fynbos and chaparral vegetation share broadly similar climate zones and
are broadly similar in some general physiognomic qualities of the dominant
species, but they are quite dissimilar floristically. They are also quite
dissimilar in incidence of ant-assisted propagule dispersal. As noted,
this character is common in the fynbos, but it is quite uncommon in
chaparral and coastal sage scrub. Reviews by Paul Zedler and others have
documented this. Managers of southern California shrublands can rest
easily in the knowledge that Argentine ants will probably not have this
same kind of effect on coastal sage scrub and chaparral communities. Dumb
luck saved some of us this time.
That being said, all her general conclusions about the effects of exotic
species on ecosystems are well taken. Ted Case and colleagues at UC San
Diego have shown that in southern California, Argentine ants forage up to
100m away from the nearest source of water. My fieldwork in coastal sage
scrub remnants in San Diego County, CA, last year found that they were
commonly present in native communities near irrigated buffers on
approximately that scale. They are a pretty good example of a biotic edge
effect on the urban-wildland interface. They undoubtedly have other
more subtle ecological effects as well. I'm curious about how they fit
into existing food webs.

Subject: Season for teaching ecology
I will be teaching General Ecology to undergraduates annually. I am trying t
decide if
I should offer the course in the fall or in the spring. The main issue is th
sorts of
lab exercises one can perform in the fall versus in the spring. My impressio
is
that
spring is not as good for outdoor exercises, because it isn't until the end
f
the
spring semester that trees leaf out and animals become more active or migran
animals
arrive.
I would like to know the opinions of members of this list about whether spri
g
or fall is
the better time of year to teach ecology. Latitude and altitude will influen
e
the answer
to my question. I'm in the Piedmont of central North Carolina, U.S.A., at ab
ut
35
degrees north latitude. However, I welcome responses from people living in o
her
latitudes/altitudes.
If I receive sufficient responses that aren't posted to the entire list, I'l
provide a
summary in a few days.
Cheers,
Joe Poston

Post-Doctoral Fellowships in Conservation Biology
The Northwest Fisheries Science Center (NWFSC), Seattle, Washington,
wishes to fill two post-doctoral fellowships in conservation or
ecological genetics.
The NWFSC is building a dynamic, multi-disciplinary research group of
scientists, post-doctoral fellows and students committed to conducting
basic and applied research that is key to solving our greatest
challenges in conservation biology. Research fields include ecology,
genetics and population biology, with a focus on modeling, quantitative
analyses of broad scale data, connecting to models to large-scale field
experiments, and using population genetic tools to address conservation
problems. We are closely associated with the University of Washington,
a five minute walk away, and have active collaborations with the NWFSC's
ecotoxicology and fish physiology and behavior groups. In addition to
providing a productive and exciting research environment, our group is
responsible for conducting analyses necessary for making critical
conservation decisions for a variety of marine and freshwater
ecosystems. Previous post-doctoral fellows and students have obtained
university faculty positions, and positions within government agencies
and research foundations.
The post-doctoral fellowships are administered by the National Academy
of Sciences' National Research Council. Applicants propose their own
original research projects, which are expected to be highly creative and
related to the conservation or ecological genetics of marine organisms.
We encourage applications from both experimental and mathematical
biologists. We particularly encourage proposals in the following areas:
* genetic basis of outbreeding depression or domestication in a "model"
fish (e.g., zebra fish or three-spined sticklebacks)
* genetic basis of adaptation in salmonids or other fish species
* genomic methods of detecting natural selection
* biogeography of marine fish, especially as related to marine reserve
design
* statistical methods for estimating fitness from molecular and
phenotypic data
* statistical methods for estimating rates of gene flow in highly
migratory species
How to apply: The postdoctoral positions are for two years, and are
administered by the National Academy of Sciences' National Research
Council. Salary is $36,000 U.S. per year. Fellows must have a Ph.D.,
Sc.D., or M.D. prior to start of the fellowship. For additional
information on research opportunities and how to apply, contact Mike
Ford at (206) 860 5612 or mike.ford@noaa.gov. Final application
deadline is Jan 15th.

32,000 GRADUATE STUDENTS GRADE THEIR DOCTORAL PROGRAMS :
POOR REPORT CARDS IN CAREER GUIDANCE, PREPARATION FOR TEACHING
(WASHINGTON, D.C.) Tables were turned this week as 32,000 graduate students
and recent Ph.D. s graded doctoral programs in a groundbreaking online
survey conducted by the National Association of Graduate-Professional
Students (NAGPS). Students graded their doctoral programs implementation
of educational practices recommended by the National Academy of Sciences,
the Association of American Universities, and other educational leaders.
Report cards for more than 1300 doctoral programs, generated from the survey
results, are available online at http://survey.nagps.org/.
ÎGraduate students often report feeling overwhelmed by the process of higher
education and helpless to change things,¼ said NAGPS President Kimberly
Suedkamp Wells, one of the survey authors and a doctoral student at the
University of Missouri Ä Columbia. ÎOur survey is important because it
provides students with the opportunity to feel like they can actually make a
difference in their educational experience.¼
Students are most satisfied in doctoral programs where they have the freedom
to pursue a broad range of career options, to make informed choices about
their own education, and to have those choices respected. While 81% of
students reported satisfaction with their programs overall, only 45% are
satisfied with their preparation for teaching and 38% with career services.
According to Adam Fagen, survey author and a doctoral student at Harvard
University, Îeven programs that excel at research may get an incomplete when
it comes to preparing students for non-research aspects of their careers.¼
ÎIt s a real problem when Ph.D. s can t function outside the university,¼
said survey author Geoff Davis, a Dartmouth math professor turned software
developer. ÎGetting science and engineering Ph.D. s into industry is the
best way to get new research and ideas out of the lab and into the world.¼
While 89% of survey respondents believed their doctoral programs are doing a
good job of preparing them for academic careers, only 52% felt prepared for
nonacademic careers.
A particular area of concern is the lack of information about the career
outcomes of former students. Only 30% of respondents reported receiving
information on graduation rates for their programs during the application
process, and only 35% received information on job placements for recent
program graduates.
Women and underrepresented minority students were less satisfied with their
experiences than their counterparts. Twenty-eight percent of women and 40%
of minority students said that their programs did not provide supportive
environments for members of underrepresented groups. ÎIf the climate of
doctoral programs is not supportive, all the recruiting in the world is not
going to make a difference,¼ said Kimberly Suedkamp Wells.
The survey results highlight model doctoral programs, and they suggest
strategies that faculty and administrators can use to improve students
educational experiences. Involving graduate students in decisions that
affect their education, providing them with more information about program
outcomes, and providing greater curricular breadth in graduate training were
all found to increase student satisfaction. Most of these strategies are
relatively easy and inexpensive to implement.
NAGPS is an advocacy organization representing 900,000 graduate and
professional students across 200 campuses in the U.S. More information on
NAGPS can be found at www.nagps.org. The online survey was funded by a
grant from the Alfred P. Sloan Foundation.

Subject: FACULTY POSITIONS AVAILABLE - UMBC
UMBC is currently seeking applications and nominations for two faculty
positions in the Department of Geography & Environmental Systems.
The UMBC campus is located in close proximity to a broad array of federal,
state, and local agencies as well as to other research institutions along
the Washington/Baltimore/Philadelphia corridor. Research on urban
ecosystems is facilitated through involvement with the new EPA-supported
Center for Urban Environmental Research and Education and the Baltimore
Ecosystem Study, an NSF- and U.S. Forest Service-funded Long-Term
Ecological Research site whose headquarters are located on campus. UMBC
also has strong partnerships with NASA-Goddard Space Flight Center through
the Joint Center for Earth Systems Technology and the Goddard Earth
Sciences and Technology Center.
One position will be filled at the rank of Assistant Professor. We are
seeking a biogeographer; the following is an excerpt from the ad:
ASSISTANT PROFESSOR: Candidates must have completed the Ph.D. no later
than August 2002 and are expected to have an active program of research
and publication, ability to attract external funding, and evidence of
commitment to teaching excellence. Preferred specialty is
biogeography/landscape ecology with research interests in ecosystem
dynamics, habitat and biodiversity, and urban ecosystems, but we will
also consider candidates with background in climate and soils.
Regardless of the area of expertise, teaching responsibilities will
include introductory physical geography, at least one upper-level course
in biogeography, and other upper-level courses in area of expertise.
Experience in utilization of GIS and remote sensing as analytical tools
that can be applied to problems introduced in upper-level courses is
desirable.
The other position, Professor and Department Chair, is open with regard
to research specialization, although our preferences are more on the
environmental/urban side. However it is particularly important that we
find a candidate with the right combination of skills in leading a
growing program with a core of geography and a growing focus on
interdisciplinary environmental science, with links to a number of
public agencies and research institutes. I have already received private
inquiries asking whether there are internal candidates for this
position; the answer is that we do not have internal candidates and we
are explicitly seeking to hire a senior-level distinguished scholar from
outside the university.
A more complete description is available at the following web site:
http://www.umbc.edu/ges/search.htm
If you have questions, or if you are able to recommend a colleague who
might be a strong candidate for one of these positions, please send an
email to
miller@umbc.edu.
If you wish to apply, look at the web address above for more complete
information. You can send curriculum vitae, cover letter, and contact
information for at least three references to Search Committee Chair,
Dept. of Geography & Environmental Systems, UMBC, 1000 Hilltop Circle,
Baltimore, MD 21250. Review of applications will begin on Dec. 10, 2001,

GRADUATE RESEARCH ASSISTANTSHIP
A graduate research assistantship is available in the
Biology Department at St. Francis Xavier University, Nova
Scotia, Canada. Funding is available in the spring of 2002.
The research will investigate aspects of movement
biomechanics in commercially important species of
crustaceans. The laboratory is fully equipped to study
movement in both larval and adult stages. Equipment for
studies of the adults consists of an underwater treadmill, a
Redlake high-speed video camera with motion analysis
software, and a variety of high-resolution video cameras
with muliplexing capabilities, and a time-lapse video
recorder. Studies on larval animals could involve work on
ecological aspects of vertical migrations, or mechanics of
swimming. The laboratory is fully equipped for both
projects. For the latter project, an experimental apparatus
has been constructed to examine fluid interactions on the
locomotor limbs using scaled-up physical models. Strain
gauges measure fluid forces, and a Dantec Particle Image
Velocimeter can be used to visualize flows. The laboratory
has strong collaborations with scientists in the Department
of Fisheries and Oceans, Moncton, N.B. Canada.

Subject: Two statistical questions
Dear Ecolog subscribers,=20
=20
Help is needed on the following two statistical questions:
=20
Question 1. =20
Growth data almost always needs to be log transformed to meet the =
assumptions of the ANOVA. According to the stat textbook "Biometry" by =
Sokal and Rohlf (1995) such data must be back-transformed and presented =
as means with asymmetric confidence intervals (3rd edition, page =
412-413). Yet few scientists seem to do that. Rather, it is general =
among researchers to furnish growth data as means with standard errors, =
despite that normality of variates was achieved through transformation. =
Are these people wrongdoers or is the general use of standard errors an =
accepted, custom way of presenting results?
=20
Question 2.
An investigator selects a large number of variables to study because all =
of them are relevant in respect to the hypothesis. However, that person =
ends up with too much data to be presented in the paper. Some variables =
are more or less correlated (e. g. growth rate, photosynthesis, shoot =
elongation rates) but exhibit slightly different response patterns. My =
question is: Can the investigator select freely between data that goes =
to the paper and data that goes to the garbage bin, thereby biasing the =
conclusions slightly? Does the need to decrease the number of presented =
variables require a random procedure? Alternatively, if one decide to =

Subject: Biotechnology Offers Benefits
Dear All:
Given that there are many other fora for discussions about GM crops, I
don't want to belabor the issues here, but given the recent interest in Bt
corn, I thought that the following is particularly significant, especially
on the subject of reductions of pesticide use.

New Study Shows That Biotechnology Offers Significant Benefits To Diverse Cr
ops
Preliminary findings of 30-crop study, shows significant savings in
production costs
www.ama-assn.org/ama/pub/article/4197-5326.html
NEW YORK (Oct 4) Preliminary research results confirm the major benefits
biotechnology has already brought to growers of crops such as soybeans,
corn and cotton, reducing pesticide use and lowering grower production
costs, according to Leonard Gianessi, a leading expert in pest management.
"For the first time, the study ["The Potential for Biotechnology to Improve
Crop Pest Management in the United States"] begins to quantify the
potential value and benefits of biotechnology for growers of a wide range
of other important U.S. crops, including papaya, citrus and raspberries
among others," says Gianessi, Senior Research Associate at the National
Center on Food and Agricultural Policy.
Gianessi spoke today at an American Medical Association media briefing on
food biotechnology. Gianessi says that the economic and environmental
benefits of agricultural biotechnology have been widely publicized for
several years, focusing on commodity crops such as soybeans, cotton and
field corn. Gianessi=EDs study, co-authored by Cressida S. Silvers, leads
this conversation in a new direction with an analysis of many novel crops,
regions and applications.
Overall, the study encompasses 30 different crops and 44 separate case
studies. The final report will be released in December; Gianessi showcases
eight of the case studies at the AMA media briefing.
"We've established that biotechnology can deliver substantial benefits to
growers of corn, soybeans and cotton," Gianessi explains."This new study
confirms that these benefits can also be realized by growers for a wide
range of crops across diverse growing regions. In many cases, biotechnology
may even save an entire industry in a state or region, such as the papaya
industry in Hawaii or the citrus industry in Texas."
Case histories illustrate variety of crop benefits
Gianessi's preliminary findings indicate a wide array of current and
potential benefits:
* Herbicide tolerant soybeans: 30 States
Genetically engineered herbicide tolerant soybeans have decreased growers=ED
annual costs by $15 per acre, which represents $735 million across 49
million acres.
* Herbicide tolerant tomatoes: California
Growers could realize savings of $30 million per year in handweeding,
cultivation and pesticide costs and a 4.3 million pound per year reduction
in pesticide use.
* Insect resistant cotton: United States
U.S. growers have earned an additional $99 million in annual net revenue by
producing an incremental 260 million pounds per year of insect-resistant
cotton, eliminating 2.7 million pounds of pesticide use annually.
* Insect resistant sweet corn: Florida
=46lorida growers could see increased production of 22 million pounds per
year, with an increased value to growers of $3.9 million per year. This
would result in a 79% percent reduction in insecticide use.
* Virus resistant papaya: Hawaii
Biotechnology is credited with saving the Hawaiian papaya industry, which
produces 53 million pounds with a value of $17 million annually.
* Virus resistant citrus: Texas
This technology is likely to help prevent the loss of the Texas citrus
industry, which annually produces a total of 622 million pounds with a
value of $48 million.
* Virus resistant raspberry: Oregon/ Washington
Using biotechnology, growers could save 10 million pounds of raspberries
per year from viral damage, add $11 million of production value, and reduce
fumigant use by 50 percent (371,000 pounds per year).
* Virus resistant tomatoes: Florida
Biotechnology could reduce insecticide use by 88,000 pounds per year, with
a savings to growers of $10.7 million/year.
"This study confirms biotechnology=EDs important role in food production. It
can contribute to growing high quality food in ways that are
environmentally attractive to growers and consumers alike. It also can help
enhance the sustainability of farmers in many regions who are threatened
with difficult economic and environmental pressures," Gianessi concludes.

Group on International Agricultural Research estimated that biotechnology
could help improve world food production by up to 25 percent."-- Dr CS

This one has no simple answer. You will get a variety of opinions about when
and to what extent you should adjust alpha values for multiple tests. One
solution to the problem of a journal not willing to publish all of the resul
s
is to
put the unpublished stuff on a website with some sort of reference in the pa
er.
The key is letting others come to independent conclusions. If you proivde th
unpublished results, each person can adjust their alpha level to their perso
al
preference.

John: To the best of my knowledge, Bt corn is NOT being legally grown in
Mexico. It would give some protection against some corn insects (eg.,
Helicoverpa armigera), so perhaps that is why some people are trying it.
Alternatively, perhaps people are trying it because they are desperate for
better insect control.

European corn borer is known to exist in at least two "pheromone races" in
Europe, both of which are also found in the USA. The borer attacks grasses
and even potato stems, and seems to have been preadapted to corn.

But as figured out by Sewall Wright, new alleles are more often lost. Other
than some insect resistance, adding Bt resistance does not cause changes in
other corn varieties. Why would it do so in land-races? As you have
alluded to ("The more commercial corn around the land-races the more likely
hybridization and fixation will occur"), the greater problem is not GM per
se, but that this episode has highlighted that commercial corn is being
grown near land races. What is being done about this more general problem?
Bt corn is approved for human and animal consumption. As already discussed
with some people off list, some of you may find additional information on
this at US EPA and FDA websites (I haven't looked lately) and at
www.plant.uoguelph.ca/safefood under the Model Farm section.

Subject: Re: Mexican native corn

In response to this statement: a new paper in American
Journal of Botany reports that several Bt corn lines have a
higher lignin content than their non-transformed isoline,
across about 10 transformation "events". Lignin contents
were 33-97% higher. (Saxena, D and Stotsky, G. 2001. Bt
corn has a higher lignin content than non-Bt corn. AJB 88:
1704-1706). The consistent increase across several
independent lines indicates that this is probably not a
positional effect dependent upon where the Bt gene was
inserted in the genome, but rather a pleitropic effect that
reflects the plant's response to expression of a foreign
protein with increased lignification. This further suggests
that this type of response might occur in any plant that
ended up expressing Bt, but many of these types of
pleitropic effects have not been explored. As the authors
assert, the increase in lignin content (which is often
accompained by increased resistance to microbial
degradation) could be beneficial with regards to processes
such as litter decomposition, soil aeration, erosion
control, etc. In fact, it could explain the observation
that some Bt lines are also more disease resistant than
their non-transformed isoline. To that end, some of the
increased resistance in Bt corn to insects could be due to
increased lignification-who knows? However, elevated lignin
content could also be detrimental-for example, it would
reduce digestibility of fodder, and could help retain Bt
intact in the soil for greater periods of time.

From: "William R. Porter" <wporter@ATTGLOBAL.NET>
Subject: Automatic camera studies
Does anyone know of any current or very recent studies employing
automatic cameras that record human and wildlife passing by the camera,
specifically in areas of public use?
I am starting a master's research project soon and will employ this
technology. The local city that runs the conservation reserve/city park
where I had hoped to do the study is very nervous about privacy issues,
and would like names of other public-accessed areas where research
cameras are being employed along with the name and phone number (or
e-mail) of an individual they may contact.
Although I have made it clear to them that the cameras used will not
record faces or other unique features of the persons walking by,
nonetheless this is apparently quite a source of concern for the city,
evocative of recent political hot-potato issues such as 'red-light'
cameras or public surveillance cameras for ID'ing wanted criminals using
face-scanning software, believe it or not.
Please feel free to respond to me off-list if desired.

Subject: Ecology of Temporary Waters (Williams)
Dear ECOLOG-L subscriber:
This is to inform you that:
"Ecology of Temporary Waters" by Dr. D. Dudley Williams
will be available again shortly from The Blackburn Press.
This is a reprint of the classic title.
Temporary fresh waters, whether seasonal rivers, streams, ponds or
microhabitats such as a hollowed tree trunk or pitcher plant reservoirs,
exhibit amplitudes in both physical and chemical parameters which are much
greater than those found in most water bodies. Organisms that live in these
types of habitat have, therefore, to be particularly well adapted to these
conditions if they are to survive. Survival often depends on exceptional
physiological tolerance or effective immigration and emigration abilities.
This book is one of the very few available on the subject and should be of
great interest to freshwater ecologists and zoologists and botanists
concerned with adaptation to extreme environments.
"This interesting book describes some of the temporary waterbodies found in
many parts of the world, such as rainpools, billabongs, and meltwater
streams ......... This book fills a gap in the literature and should
stimulate further work on these fascinating waterbodies."
Rosalind M. Pontin in The Biologist (1988) 35 (3): p. 162.
"Here is a book on an unusual topic but one that will certainly prove to be
thought-provoking ..... it has a mass of material not easily available to
ecologists, limnologists, botanists and zoologists, especially those
concerned with plant-animal adaptations ...... Professor Williams is to be
congratulated for making easily available the contents of this new book."
Richard E. Schultes, Botanical Museum, Harvard University, Massachusetts. in
RHODORA (1988)
"There really aren't any other books on the biota of temporary bodies of
water, and this one presents a decent introduction. Although the book is
short, Williams covers a lot of territory - the strength of this book lies
in its breadth ..... certainly as an introduction and as a teaching aid, the
Ecology of Temporary Waters is a useful addition."
Michael Berrill, Trent University, Ontario, Canada in The Quarterly Review
of Biology (1988) 63 (4): p. 473.
"An interesting little book which speaks for itself about the importance of
temporary water bodies, addressing beneficial and deleterious factors and
dealing with both basic and applied apsects. It is logically organized and
written in a readable and interesting fashion ..... an interesting and
informative book for general reading; a supplementary reference source for
college courses in aquatic biology."
T.L. Hufford, George Washington University. in Choice (1988) July/August: p.
1716.
ISBN 1-930665-49-0

Project Title: Groundwater-Surface Water Interactions and Relation to Water
Quality in the Everglades
Salary: $23,177.44 - $27,593 per year ($11.143 - $13.27 pre hour) pay
commensurate with experience
Location: Reston, VA
Start date: ASAP, Late Nov into Dec
Deadline: Nov 2, 2001
Duration: One year
Description of Project: The present project has the goal of improving
scientific understanding of the Everglades water balance and its effects on
transport and transformation of dissolved chemical constituents, including
contaminants such as mercury and excess nutrients. Improved field methods
are needed to quantify water movement and exchange of dissolved chemicals
between surface water and ground water in this wetland environment. This
scientific knowledge is considered essential to successful restoration of
the Florida Everglades. The detailed objectives of the project are to (1)
develop improved methods to quantify vertical fluxes of water (referred to
as discharge and recharge) between ground water and surface water, (2) use
those improved estimates of recharge and discharge to develop mass balances
for important chemicals such as mercury and nutrients, and (3) relate
recharge and discharge to subsurface hydrogeologic properties, management of
surface-water levels in canals and water conservation areas, and regional
climate fluctuations and water balance in South Florida.
Mentor: Judson Harvey is the project chief and mentor (703-648-5876) located
at the headquarters office of the U.S. Geological Survey in Reston, VA. The
intern will work closely with the mentor and will also work with other
Everglades scientists located in the Reston office, as well as universities
and federal and state institutions in Florida. The intern can expect to
travel to Florida to perform fieldwork approximately 4 times per year. In
the field the intern will work with a team of USGS scientists and scientists
from Universities and from the South Florida Water Management District
(SFWMD).
Objectives of Internship: The objective of the internship is to provide a
student who has an interest in furthering their knowledge of hydrology and
environmental science with practical work experience on problems that
influence restoration of the Florida Everglades. The intern will extend
their knowledge through interaction with the U.S. Geological Survey (USGS)
and the South Florida Water Management District (SFWMD). Those two
organizations are leaders in environmental research and its practical
application to water management problems. The intern will work closely with
the project chief, and other project collaborators and associates in
acquiring field data, in reducing, checking, and entering and manipulating
the data in data bases, analyzing and interpreting data, and preparing final
graphics, tables, and text for reports and publications.
Tasks:
Based on supervision and instruction from the project mentor, and on
cooperation and collaboration with project staff and other collaborators,
the intern will undertake the following...
1. Measure hydrological and chemical parameters from levees, airboats, and
wetland research sites in the Florida Everglades while maintaining a field
notebook with accurate and comprehensive entries. Check data, enter data
from field notes or translate data from electronic media, reduce and
transform data, graph data, and append data to permanent project databases.
2. Analyze data, including preparing graphs and tables for preliminary
interpretation, and executing hydrological or statistical computer programs
to generate results for final interpretation. Communicate with other
departments at SFWMD or USGS to acquire related additional information from
other databases.
3. Participate in preparing final data interpretations in the form of
published reports and manuscripts for submission to professional journals.
Work Experience Benefit(s) to Intern:
The intern will be involved with a project that contributes directly to
developing plans for the restoration of water flow and water quality
conditions to preserve the hydrological and ecological character of the
Florida Everglades. Intern will become familiar with a variety of
environmental field methods and mathematical analysis of hydrologic data,
and will gain a better understanding how basic research can be applied to
solve practical problems wherever wetlands and shallow water environments
are a key concern.
Specific Qualifications Desirable: A college-level background is required in
either physics or math, along with a background in either chemistry or
ecology (biology). An interest in hydrologic sciences is also required, in
addition to excellent verbal and written communication skills. Desirable
additional skills include computer programming, GIS (i.e. Arc-Info),
spreadsheets (e.g. Excel), database programs (e.g. Access), and statistical
analysis programs (e.g. SYSTAT or SAS).
Overtime Requirements* (check appropriate box):
1. Day trips away from site where distance traveled or time required on site
necessitates a work day greater than 8 hours: Rarely.
2. Extended trips away from home: Yes, occasionally, approximately 4 times
per year.
3. Time-critical experimentation in laboratory that necessitates a workday
greater than 8 hours: Occasionally.
Required Protective Equipment: In the office this includes knowledge to
reduce repetitive stress at keyboard. In the field protective equipment
includes hat, sunglasses, sun block, backpack, water containers, and general
knowledge of safety procedures in the field.

Landscapes host intrinsically complex dynamics: biotic and abiotic processes
occur within and across the landscape yielding patterns of influence that
affect these processes in turn. Ecological patterns and processes weave
their mutual causality through space and time. Human actions and decisions
in the landscape are an integral aspect of the mode and tempo of how
dynamics unfold across the landscape. The theme for the 17th Annual U.S.
Landscape Ecology Symposium is 'Landscapes in Transition: Cultural Drivers
and Natural Constraints'.
The theme stems in part from the meeting location: the Great Plains region
of North America has seen successive waves of anthropogenic landscape
change. Of increasing interest is the integration of socio-economic and
socio-political perspectives into the theory and practice of landscape
ecology.
Cultural drivers encompass a range of system forcings, including abrupt
institutional or political changes, e.g., the collapse of communism,
onset/cessation of armed conflict+ADs- abrupt or phased policy change, e.g.,
Homestead Act, Endangered Species Act, Conservation Reserve Program+ADs- and
changes in cultural preferences, e.g., shifts in urban/suburban/rural
demographics. Natural constraints on system responses can include
reconfiguration of habitat, metapopulation connectivity, and loss of
biodiversity+ADs- local hydrometeorological dynamics and drainage/deposition
l
networks+ADs- partitioning of surface energy balance+ADs- and the fertility
f
soils
and the resilience of belowground communities to disturbance.
We expect attendance by over 400 ecologists, landscape architects,
geographers, planners and other professionals from across the region, the
continent, and beyond. The program will include three plenary speakers, six
special sessions, contributed oral and interactive (poster) sessions,
technical workshops, and field trips emphasizing innovations in basic and
applied research, analytical tools, and the integration of ecological
understanding into policy and ecosystem management.
We invite contributions on all aspects of landscape ecology and any
geographic setting. We encourage presentations that highlight or complement
the Symposium theme. Of particular interest are the following topics:
+ACo- agroecology, agroforestry, and the landscape ecology of grasslands+ADs
+ACo- innovations in geospatial information technologies as applied in lands
ape
ecology+ADs-
+ACo- historical and contemporary landscape ecology of the Great Plains+ADs-
+ACo- landscape ecology and biodiversity+ADs-
+ACo- the changing ecology of lakes, rivers, and wetlands in central North
America+ADs-
+ACo- landscape ecology and natural disturbances (e.g., severe storms, hail,
fire)+ADs- and,
+ACo- landscape ecology and natural history museums.
