Subject: distance grad courses
Does anyone know of any distance learning graduate level courses in Ecology
and Evolutionary Biology?
I am not interested in entirely distance grad programs, but rather courses
that may offer some unique thing I can't get at my university, or an
opportunity to study under a respected ecologist/evolutionary biologist in
some particular area, etc.
I will post a summary to the list!
Thanks in advance,

JMP (www.jmpdiscovery.com) and other packages can do this too. In JMP you c
oose "Analyze -> Fit Y by X". Then on the plot choose "Fit Orthogonal ->
Equal variances". You will get the following output:
Bivariate Fit of y By x

If you don't mind some programming (for example in R or octave) you
can use a bootstrap method
1) compute the difference in slope for the original data
2) mix the two data sets
3) draw randomly with replacement two bootstrap data sets of the same
size as the original ones
4) compute the difference in slope under H0: the two data-sets come
from the same population
5) repeat 3+4 b times (b>300) to get the empirical distribution of
the difference under H0
6) test by percentiles whether the original difference was
significantly different.

Subject: Re: Other: Impact of overhead costs
>From everything that I can tell, in the U.S., the "overhead costs" progr

has been detrimental, though it has been intended to be beneficial. A
couple of simple reasons for my statement: (1) The few well publicized
instances of abuse, such as the high profile west coast university that had
a negotiated 70% overhead cost agreement with the feds, and used overhead to
pay for flowers and other perks for offices. That created a sour taste for
many people. (2) The misunderstandings among faculty, who produce grant
applications, administrators, who depend on overhead for running the
institution, and granting agencies about what are appropriate uses of the
money. (3) The administrations that have actively discouraged faculty from
applying for grants programs that specify a low or no overhead cost because
the grants programs hope to make sure that the money is used for the
purposes of the program, while the administrations hope to have overhead as
institutional income.

Subject: Graduate Student Positions in Invasion Biology,
Ecological Forecasting, and Aqua
Graduate Student Positions in
Invasion Biology, Ecological Forecasting, and Aquatic Ecology
Graduate Research Assistantships are available in David Lodge^Òs laboratory
beginning in summer-fall 2003.
Current research in Lodge^Òs lab focuses on the following questions, all of
which relate to important on-going global environmental changes.
1) What impact do consumer species have on their resources? Consumer species
that we have studied in detail include algivorous snails, herbivorous
waterfowl, predacious fishes, and omnivorous crayfishes. One on-going
project tests the impact of waterfowl, including booming snow goose
populations, on aquatic and wetland vegetation in Lake Mattamuskeet, NC.
Opportunities exist for continuing work on this project.
2) How do the structure of communities impact lake and stream ecosystem
function? Recent experiments at the UND Environmental Research Center
(UNDERC) have focused on benthic-pelagic links involving interactions
between fish & macroinvertebrates, Daphnia & macrophytes, and benthic algae
& phytoplankton. On-going work uses naturally occurring stable isotopes as
tracers for energy flow through benthic and pelagic food webs affected by
invasive rusty crayfish. In addition, we are conducting an adaptive
management experiment on the control of rusty crayfish. Continued funding
will likely be available from for work on these topics.
3) Can we forecast the introduction, establishment, dispersal, and i
pact
of nonindigenous species on native species and ecosystems? We are studying
the pathways by which alien species are being introduced, the interactions
(e.g., competition, predation, hybridization) that alien species (e.g.,
zebra mussel, ruffe, and rusty crayfish), have with native species, and how
those interactions affect community and ecosystem function. We are also
using a variety of statistical, analytical, and simulation modeling to
forecast the establishment and spread of alien species in the Great Lakes
and elsewhere. In collaboration with economists and mathematicians, we are
combining economic and biological information to inform risk analyses of
invasive species; to guide the development of management practices; and to
guide allocation of resources to prevention or control to best reduce the
probability of future invasion disasters. Funding is available from a new
5-year NSF grant.
My students, postdocs, and I conduct field work in the inland lakes and
streams of northern Indiana/southern Michigan, UNDERC in the upper peninsula
of Michigan, the Great Lakes, the coastal plain of North Carolina, Denmark,
and Kenya. Current funding comes from NSF, EPA, NOAA Sea Grant, USDA
(Forest Service), the Great Lakes Fisheries Commission, the Lilly
Foundation, and the US Department of Education.
Excellent laboratory facilities are available in the Hank Family Center for
Environmental Studies where most Ecology, Evolution, and Environmental
Biology faculty are housed. Also on campus, the Center for Environmental
Science and Technology (CEST) has a large variety of instrumentation that is
available at no cost to university personnel. The University of Notre Dame
Environmental Research Laboratory (UNDERC) is an active research station
located in the Upper Peninsula of Michigan.
All graduate students in our program are fully supported for 12 months and
full tuition is provided by the Graduate School. For more information, see

Applications may be submitted to the Graduate School electronically. The
application deadline for Fall 2003 admission is 1 February 2003. However,
early application to the Graduate School is encouraged to ensure access to
all sources of funding. Early communication directly with Lodge is also

Dear colleagues,
I have been searching for information regarding root biomass relative to
soil mass in freshwater wetlands but have hardly found anything. I am
especially interested in papers in which a cross-section was cut in soil
and the relative mass of roots vs. soil per unit volume was determined.
Would anyone know of any papers on this or closely related topics? If no

Linda,
You may want to take a look at the following references:
Gamradt, S. C., and L. B. Kats. 1996. Effect of introduced crayfish and
mosquitofish on California newts. Conserv. Biol. 10:1155-1162.
Schmeider, R.R., and R.S. Nauman. 1994. Effects of non-native aquatic
predators on premetamorphic California red-legged frogs (Rana aurora

Gambusia were found to prey upon the eggs (and larvae, I believe) of the
California newt (Taricha torosa torosa) and the California red-legged
frog (a federally listed species). My general opinion is that Gambusia
are bad news to any aquatic breeding amphibian. As for Gambusia control
methods, good luck! I'd like to hear what control methods are
discussed.

Subject: Gambusia in salamander breeding ponds
I am looking for information about the potential impact of
mosquitofish on a breeding population of spotted salamanders and, if the
impact is likely to be severe, advice on getting rid of the fish.
My campus in central Virginia has a lovely, tiny (about 20ft x 40ft
x 2-3ft deep) woodland pond that is the breeding site for a large
population of spotted salamanders every spring (and is also home to
other herps and aquatic insects). The pond has been fish-free for many
years, but this fall we have discovered a large, uninvited population of
Gambusia.
Will Gambusia eat or ignore newly hatched salamanders? Is it
feasible to rotenone the pond? Introduce a predatory fish which we
could later remove? Electrofish?

BERKELEY, CA -- In the spring of 2001, two robotic Carbon
Explorer floats recorded the rapid growth of phytoplankton
in the upper layers of the North Pacific Ocean after a
passing storm had deposited iron-rich dust from the Gobi
Desert. The carbon measurements, reported in the October 25
issue of Science, are the first direct observation of
wind-blown terrestrial dust fertilizing the growth of
aquatic plant life.
A group of scientists led by oceanographer James K. Bishop
of Lawrence Berkeley National Laboratory's Earth Sciences
Division engineered the deep-diving Carbon Explorers to
measure particulate carbon in the upper thousand meters of
the ocean. The Carbon Explorers are modified SOLO floats
(Sounding Oceanographic Lagrangian Observers), originally
designed by Russ Davis of the Scripps Institution of
Oceanography to measure temperature and salinity at various
depths. A growing number of SOLOs are now adrift in ocean
currents around the world, as part of the international
Project Argo to study ocean climate variability.
Two of the specially modified Carbon Explorers were launched
April 10, 2001, from the U.S. Coast Guard's icebreaker Polar
Star near Ocean Station PAPA, in subarctic waters a thousand
miles west of Vancouver Island. The Carbon Observers were
programmed to sample the depths and return to the surface
three times every two days, regularly sending data to
satellites overhead. The two floats, controlled from shore,
returned a virtually unbroken stream of information for the
next eight months, through December, 2001.
Ocean Station PAPA, at 50 degrees north latitude, 145
degrees west longitude, is one of the few sites in the world
whose waters have been studied for decades using shipboard
instruments. PAPA thus provides an excellent baseline for
observing variations in the carbon products of
photosynthesis at different depths.
"The plants that fix carbon in the ocean typically live,
reproduce, and die on day-to-week time scales," Bishop says.
"The beauty of the Carbon Observers is that they keep on
working day in and day out, for seasons at a time, matching
the biological rhythms of the sea in a way that ships and
other systems cannot."
Phytoplankton growth is affected by factors like nutrient
concentrations, light, temperature, salinity, and the way
the sea water mixes. Earlier studies at PAPA suggested that
growth in the region was also limited by a lack of dissolved
iron in the water. The Carbon Observers would soon put that
assumption to the test.
Testing the iron hypothesis
In the 1930s oceanographers first began to suspect that
terrestrial dust storms play a key role in phytoplankton
growth in the so-called high nutrient, low chlorophyl (HNLC)
areas of the ocean, whose concentrations of dissolved iron,
an essential micronutrient, are much lower than in other
regions. By dissolving carbon in seawater and by fixing it
as biomass or inorganic particulate matter, phytoplankton
regulates carbon dioxide in the atmosphere and thus helps
regulate global climate.
In the 1980s, oceanographer John Martin gathered these facts
in his "iron hypothesis," which proposed that by fertilizing
plankton growth with iron, global warming could be offset.
Iron fertilization can indeed cause plankton "blooms" in
HNLC waters, as several expeditions including Soiree (the
Southern Ocean Iron Enrichment Experiment) in February 1999
and SOFeX (the Southern Ocean Iron [Fe] Experiment) in
January and February 2002 have proved by pouring dissolved
iron into HNLC areas in the Southern Hemisphere. But prior
to the spring of 2001, fertilization by iron transported in
terrestrial dust storms had never been observed directly.
Three days before the launch of the Carbon Observers on
April 10, a NASA satellite recorded a large dust storm
originating near the Gobi Desert in China and Mongolia; on
the day of the launch, the dust cloud was over Japan and
heading for the North Pacific. It reached Ocean Station PAPA
on April 12, where it kicked up the waves and deposited a
large amount of dust.
Although high waves temporarily kept the Carbon Observers
from reporting by satellite, data collection continued
uninterrupted through the storm. Five days after the storm
passed, the floats reported rising concentrations of
particulate organic carbon; the concentration almost doubled
in the next two weeks.
Bishop notes that "the timing of this natural increase
matched the timing of plankton growth after iron was
artificially added to Southern Ocean waters during Soiree
and SOFeX, a good indication that iron fertilization was the
cause in the North Pacific as well."
Plankton growth following the storm over Ocean Station PAPA
was confirmed when NASA's SeaWiFS satellite got a glimpse
through the clouds and saw the sea surface turning greener
with chlorophyll. These satellite observations further
supported the supposition that iron and other micronutrients
from the Asian dust storm had fertilized the
phytoplankton.
For the first time, one of the key assumptions of the iron
hypothesis had been observed in nature: wind-blown dust does
stimulate plankton growth in otherwise unproductive waters.
But how long is the atmospheric carbon thus taken up by
phytoplankton sequestered in the ocean?
Jim Bishop and his colleagues hope Carbon Explorers and
other instruments can soon find out what proportion of
particulate organic carbon sinks all the way to the deep
ocean. "Until we can answer that question with some
precision, whether or not large scale iron fertilization of
the ocean would be useful in slowing global warming will
also remain unanswered. There's a huge amount of science
left to be done in the next decade to assess the ecological
changes and the downstream effects of the technique. We've
only scratched the surface."
The National Oceanographic Partnership Program supported the
development of the Carbon Explorers in a collaborative
project including Berkeley Lab's Earth Sciences Division,
the Instrument Design Group at Scripps, and WETLabs, Inc. of
Philomath, Oregon. Other agencies that supported the Carbon
Explorer program at Ocean Station PAPA include the National
Oceanic and Atmospheric Administration's Office of Global
Programs, the U.S. Coast Guard, and the U.S. Department of
Energy's Office of Science, Ocean Carbon Sequestration

Subject: Amazon Deforestation Could Affect U.S. Climate [JGR-Atmos.]
Amazon Deforestation Could Affect U.S. Climate
Using mathematical simulations, a Duke researcher has concluded that
further
destruction of the Amazon rainforest could affect the climate in the
U.S.
and elsewhere.
Thursday, October 24, 2002 | New mathematical simulations of climate
behavior by Duke University researchers indicate that deforestation in
the
Amazon can cause a reduction of rainfall in the Midwestern United States
and
the Dakotas in the summer, when precipitation is most needed for
agriculture.
"What this suggests is that if you mess up the planet at one point, the
impact could have far-reaching effects," said Roni Avissar, chairman of
the
Department of Civil and Environmental Engineering
<http://www.egr.duke.edu/Depts/civil.html> at Duke's Pratt School of
Engineering. "You have to be careful not to look at only one area."
Avissar and research associate David Werth report their findings in the
Oct.
27 issue of the Journal of Geophysical Research-Atmospheres. [dla
emphasis.]
The study was supported by grants from the National Aeronautics and
Space
Administration.
They conducted their research by using as a climate simulator a set of
mathematical equations that describe the behavior of Earth's atmosphere.
Each simulation uses a variety of data such as heat release, humidity,
evaporation, precipitation, sea surface temperatures, soil moisture
transfer
and the like that would exist under different scenarios ranging from
current
conditions to a completely deforested Amazon basin.
It has been estimated that 15 percent of the Amazon rain forest already
has
been cut and turned into pasture, but the researchers looked at what
might
happen if the entire Amazon were converted to pasture land.
"Basically, what we see is a reduction of rainfall over the Amazon,"
Avissar
said in an interview. "This reduction of precipitation occurs most of
the
year but is most significant -- on the order of 15 percent to 20
percent --
during the summer, from February to March. Of particular interest is
that we
see a correlation with climate changes, primarily reduced precipitation,
in
other parts of the world."
Avissar said the simulation showed a noticeable reduction of
precipitation
-- 10 percent to 15 percent -- during the summer in the Dakotas of the
United States and in the Midwest Triangle of Oklahoma, Arkansas and
Missouri. Central America and the Gulf of Mexico also had reduced
rainfall
in the simulation, as did an area over the western Pacific Ocean and a
region over the Indian Ocean.
Just what is happening in such simulations is not clear, Avissar said,
but
the climatic mechanisms may be similar to altered wind circulation that
suppress Atlantic Ocean hurricanes during the Pacific Ocean warming
phenomenon called El Nino.
Avissar said he could not blame recent drought conditions in the United
States on deforestation in the Amazon because the Duke simulations
looked at
a hypothetical situation that is much more severe than what currently
exists
in the Amazon, which covers nine times as much land as Texas.
"What we say here is that if you modify the landscape of the Amazon, it
affects other parts of the world. It is not enough for a country to make
national decisions about land use because it does not just affect the
water
resources of your own country."
He and Werth are now looking for similar effects of deforestation in
other
parts of the globe. They also are developing a more refined mathematical
model that may be able to predict the results of partial deforestation,
Avissar said.

Subject: Re: Tropical Tree Diversity - How High?
When comparing richness of different regions, you can discover some pretty
amazing things.
For example, a recent paper comparing the richness of biogeographic
provinces demonstrated that the island of Crete has a higher diversity
(number of species per thousand square kilometers) than Costa Rica.
Using the same mathematics (i.e. dividing the richness by the area) I find
that Oklahoma is the richest recorded region by far. I find, on average,
70 species per 0.01ha. This gives it 700000000000 species per thousand
square kilometers.
OK, you figured out I am being facetious. However, this kind of diversity
standardization (i.e. dividing richness by area, or number of individuals)
is shockingly common in the literature ? and even more common in
manuscripts.
I'm writing this message to urge authors to be mindful when standardizing
biodiversity measures. Cut down on the risk of rejection! And if the
paper squeaks by peer review unchallenged, prevent the potential
embarrassment. Editors and referees: please be vigilant; this kind of
error is not hard to catch if you are alert. If not caught, it is
possible that future authors will repeat the mistake, citing previous
papers!
For an excellent discussion of the topic, see Gotelli and Colwell. 2001.
Quantifying biodiversity: procedures and pitfalls in the measurement and
comparison of species richness. Ecology Letters 4:379-391. This paper
largely points out the obvious, but it is clear that there is a need to do
so.

Subject: Gambusia in salamander breeding ponds
I am looking for information about the potential impact of
mosquitofish on a breeding population of spotted salamanders and, if the
impact is likely to be severe, advice on getting rid of the fish.
My campus in central Virginia has a lovely, tiny (about 20ft x 40ft
x 2-3ft deep) woodland pond that is the breeding site for a large
population of spotted salamanders every spring (and is also home to
other herps and aquatic insects). The pond has been fish-free for many
years, but this fall we have discovered a large, uninvited population of
Gambusia.
Will Gambusia eat or ignore newly hatched salamanders? Is it
feasible to rotenone the pond? Introduce a predatory fish which we
could later remove? Electrofish?

Subject: Re: Gambusia in salamander breeding ponds
Aren't the salamander larvae are for the most part benthic? The
mosquitofish feed mostly on invertebrates, and mostly in the water column
and near the surface. They will take other small fishes, but I really doubt
that the salamander larvae are in any danger, unless they live well up in
the water column. Aren't there enough insect larvae, crustacea and so on to
keep them busy?
Getting rid of _Gambusia_ in a pond? How long can the salamander larvae
tolerate being in a refuge tank, and can you handle them successfully
without causing so much stress as to kill many of them? Ponds and springs
have been successfully "renovated" when undesirable fishes invaded by an
intensive program of removal of the DESIRED species in large numbers, and
then using rotenone in the pond. Once the rotenone has done its evil deed
and the toxicity of the water has declined, the desired animals are
returned. Of course, non-target species suffer, too. You might contact
Gary Garrett of Texas Parks and Wildlife Department or Dr. Clark Hubbs of
The University of Texas at Austin's Integrative Biology Section. They have
used this procedure to renovate ponds and streams occupied by endangered
fish species but invaded by undesirable competitor species.

Subject: graduate research opportunity in plant-pollinator interactions
Graduate research opportunity (M.S. or Ph.D), Department of Environmental
Sciences, University of Virginia, Charlottesville.
I am looking for a self-motivated graduate student to carry out individual
research in the general area of plant-pollinator interactions. Specific
possible research areas include the effect of pollen nutrient value on host
plant choice and larval development by solitary bees, the effect of pollen
structure on pollen digestibility, and the influence of landscape
management on pollinator populations. Additional areas of plant-pollinator
interactions are open, depending on student interest. The research should
be carried out at or near Blandy Experimental Farm, one of the ecological
research stations of the University of Virginia. Facilities at Blandy
include a research greenhouse, research screenhouse, basic lab and field
equipment, large areas of land available for manipulation, and natural
areas typical of the Shenandoah Valley. The Blue Ridge Mountains are nearby
and present a variety of additional habitats. Housing is available as
needed at the research station, which is a 2 hour drive from
Charlottesville, Virginia and 1 and a half hours from Washington, DC.

Does anyone out there have experience running a class trip to the Galapagos
slands for undergraduate credit? If so, I'd like to hear:
1. was it a positive experience for you and students?
2. was it a logistic nightmare, as I expect?
3. how much did you arrange yourself, and how much did you arrange thru an
gent?
4. what agent(s) did you work with, and would you recommend them?
5. did you have students do projects of some sort on the trip?
6. what things did you do to make the course affordable to your students?

Subject: Other: Impact of overhead costs
The Canadian government is currently in the process of implementing
an "overhead costs" program. The aim is to reimburse universities
for the direct costs of research-related activities as a percentage
(perhaps as much as 40%) of the total research grants received by
each university from certain federal agencies.
As the program is still in its planning stages, it may be possible to
influence how the program works. I am sending this email to
colleagues in ecology and evolution in other countries that have
overhead costs programs. In your opinion, has the program had a
positive or negative effect on your field? If so, how and why? Do
you have any comments or recommendations for how the program could be
structured so as to maximize the benefits to all fields?
Many thanks, in advance, for your input!
