Subject: Global Warming
Dear List-folks
I read an article by Paul Dayton a year or so ago I would guess. It
was an article about fisheries but I think it relates to the global
warming discussion in a general sense. He mentions a need to shift
"the burden of proof" from those who wish to conserve a resource to
those who want to exploit that resource .
To simplify his point, instead of the need to prove harvesting a
resource has an effect on the resource, there must be proof that
harvesting a resource has little or no effect on the resource, or at
least it is sustainable, whatever that means.
I realize the difficulty analyzing and interpreting climate change
data. However, there are some large-scale experiments happening in
the world today, and unfortunately, the sample size is often 1 (as in
only one planet). I am reminded of a comedy routine by Bill Cosby
(subsequently "sampled" in the movie Independence Day), where Bill is
having surgery, when the surgeon was working away, and said "oops".
"What do you mean saying oops there?" Bill asked frantically, waking
up from the anaesthetic. " When I say oops I know what I've done.
What did you do there?".
Well, that is my $ 0.02.
Cheers,
Jon

Subject: Analyses of Similarity (ANOSIM) for Diet Analysis
Dear Ecologgers,
I have a student who is comparing diets of wild sheep between sexes and
among seasons. The diet composition is based on analysis of scats.
Gender is known because he saw the animals defecate. Eight samples
(four from males and four from females) were collected every two weeks
for one year.
I have just started learning about the ANOSIM procedure. It appears to
me to be much more powerful than other analyses that have been used in
the literature for diet comparisons.
I would appreciate receiving comments from anyone who has used ANOSIM
regarding whether it seems suitable for this type of analysis. Also, is
this procedure available through any statistical package other than
PRIMER? Does anyone have a strong preference for some other type of
analysis that seems more suitable?
Thank you,
Jim Mueller

Subject: Simple articles for seminars ?
Dear friends, now I have almost 20 references on articles to be used as
seminars in undergraduate courses of Quantitative Ecology but.....
several of them are not easy for such students and then I would like to
request that if you have a suggestion, please SEND me, until the end of
July, your reprint by e-mail (PDF) or a reprint by snail mail (see my
address below). I need to read the article to include only the material
matching with the original idea. I will send all the information for the
list in the next weeks. Thanks... Voltolini
My Original Message:=20
Dear friends, I am preparing an introductory course on Quantitative
Ecology for undergraduate students and I am looking for simple articles
to be used as examples in seminars. The idea is to use simple, short and
experimental studies as examples to show how statistical analysis is
important for a lab or a field biologist. I am thinking more in articles
using simple analysis like chi-square, t test, ANOVA, regression,
correlation, simple multivariate analysis, etc. and.... less in complex
analysis like time series, survival analysis and complex multivariate
models (the idea is to attract the attention of the students and not to
scare them !). If someone is interested, I can send my results for the
list and, in this way, we could start a "seminar directory" with files
to be shared with all interested people in teaching Ecology with a
quantitative approach! PDF and Word formatted texts are preferred
because I can send them back for everyone. Thanks for any help!

Subject: Toxic Algae Found in Chesapeake Bay and Adjacent Waterways
http://www.nytimes.com/2001/07/10/science/10CHES.html Toxic Algae
Found in Chesapeake Bay and Adjacent Waterways
NNAPOLIS, Md., July 9 - Biologists monitoring Maryland waters have found
widespread traces of a toxic algae along with several kinds of algae
that could seriously harm life in the Chesapeake Bay.
The State Department of Natural Resources directed the biologists to
begin regularly checking for the toxic algae, Pfiesteria, after it
killed fish and sickened people on some Eastern Shore rivers in 1997.
In addition to finding Pfiesteria, the scientists encountered two
previously unknown varieties of algae that could kill bay creatures.
They also found that some familiar algae blooms could be harmful to
life.
While those algae have not been linked to human illnesses in the United
States, evidence indicates that they can kill underwater grasses,
prevent oyster larvae from hatching, contaminate shellfish and damage
other fragile bay life. [snip]

Subject: Internship Opportunity - Jug Bay Wetlands Sanctuary, Maryland
Ornithological Research Intern; Fall 2001
The Jug Bay Wetlands Sanctuary is a 620-acre research station and wildlife
preserve located on the Patuxent River in central Maryland. Long-term
ecological studies were initiated here in 1985. A variety of projects are
carried out by staff naturalists and by researchers from nearby universities
and other research institutions. The Sanctuary is open to the public and
educational programs for all ages take place. The Sanctuary is part of the
Chesapeake Bay National Estuarine Research Reserve.
We are accepting applications to participate in an ongoing study of songbird
use of a section of the Sanctuary for breeding and migration and the effect
habitat management, including shrub and native warm season grass plantings,
is having on this use. The intern will work under the supervision of the
sanctuary director. Day to day activities will be determined by a Master
Bander and Certified Banding Trainer. Applicants should be able to work
independently, have a high degree of self-motivation, and be comfortable
working with people of all ages and skill levels. Previous experience mist
netting and banding songbirds is desired. One position is available for fal
2001.
Duties
The intern will be required to rise early (before sunrise) and open mist net
on days the banding station is operating, normally three days a week. Some
maintenance of nets lanes will be required. The intern will be responsible
for assuring that necessary banding equipment is on hand and operational.
The intern will also enter the banding data into an Excel spread sheet and d
some quality control. There will be an opportunity to participate in other
ongoing research projects at the Sanctuary, as time permits. The Sanctuary
Director may also assign additional task as he sees fit.
The intern will be required to complete an independent research project,
which can relate directly to his or her daily activities. For example, the
project could involve summarizing, analyzing, and reporting on bird netting
data collected to date or examining some aspect of the effects of the habita
management project; perhaps looking at foraging behavior or habitat use.
Stipend Award
$1,200 stipend and free on-site housing. The stipend is provided by the
Friends of Jug Bay, a citizens group that supports Sanctuary programs.
Location
The Jug Bay Wetlands Sanctuary is located 15 miles east of Washington, DC.
and includes one of the largest freshwater tidal wetlands on the East Coast.
Annapolis is 18 miles to the North and the Chesapeake Bay is 12 miles to the
East.
Dates
The intern position is for a three-month period. The anticipated start date
is August 15 and the completion date is November 15.
Work Schedule and Housing
Intern will work five full days/week and have two days off each week. Housin
conditions in a three-bedroom, 100-year-old farmhouse are adequate, but not
luxurious. The house location, however, is spectacular. It is on the edge
of the Patuxent River, adjacent to fields that are managed for wildlife, wit
great views of eagles, herons, geese, and other birds. There is a community
organic garden nearby which can be used in exchange for a modest contributio
of labor. The location is somewhat remote so an automobile is a definite
plus. Bring your own CD player and computer. On occasion other researchers,
volunteers, and visitors may use the house
Qualifications
Applicants must have an undergraduate degree with a major in the life
sciences. Must be highly motivated and capable of independent work. Knowledg
of Excel is desired. Mist netting and bird banding experience is a plus, as
is familiarity with aging/sexing techniques described in Pyle. Work is often
in wet and muddy habitats. A sense of humor is important.
Deadline: Applications must be received by July 25, 2001.
Application Procedures
Please send the following information (written communications only):
1. Resume
2. Cover letter or statement of experience, qualifications, and career goal
3. Names/phone numbers/e-mail addresses of 3 academic/professional
references

***************
I've used the hemispherical photography method and found it is a good
method if you want to measure direct and indirect light levels in the
understory of tropical wet forest. There are a couple of papers (see
below) that have used this method, and I was fortunate to be at a
field site at the same time as another researcher who actually had
done it before and was kind enough to loan me the equipment and even
analyze the photos.
The shortcomings of this method that I know of are:
1) you need a fisheye camera lens (these are not usually cheap)
2) someone who is proficient (and equiped) for doing the computer
analysis of the photos
papers that detail the method:

photography. Los Alamos National Laboratory, LA-11733-M.

canopies for remote sensing in optical and thermal infrared regions.

The answer depends partly on the geographic extent of the area that you
will be operating in. If you are working in a climatically homogeneous
area, with little variation in annual photosynthetic photon flux density
between sites, then the LAI-2000 would be a great solution. It does NOT
give you absolute light measurements, it gives you the *percentage* of
diffuse light reaching a given point in the understorey. WHich is fine fo=
r
most purposes if you are comparing points within a climatically homogeneo=
us
area. You can check the instrument out on Li-Cor's web page I imagine. Yo=
u
would need two of them - and they are not cheap, but they are easy to use
and extremely useful for addressing any number of ecological questions. Y=
ou
can collect a lot of good quality data in no time at all. It has a couple
of minor drawbacks - you can only use it on cloudy days, or when the sola=
r
disc is below 15=BA (early morning or late afternoon), and it can't
distinguish between the north and south sides of a gap, which usually
differ quite a lot in total PPFD. Even so, some people from Univ. of
Minnesota (Machado & Reich) found that LAI-2000 readings correlate very
well with direct measurements of PPFD within a given stand. You can also
estimate leaf area index with the LAI-2000, although it doesn't do quite =
so
well at this other job.
If you are comparing sites that are scattered along way apart then you
would need some absolute measure of PPFD as well as, or instead of your
LAI-2000 measurements.

Subject: POST-DOCTORAL POSITION IN THEORETICAL AND STATISTICAL ECOLOGY
POST-DOCTORAL POSITION IN THEORETICAL AND STATISTICAL ECOLOGY: University of
California, Santa Barbara.
Applications are invited for a post-doctoral researcher to participate in a
study of ecological indicators in wetlands. The research includes
statistical analyses aimed at identifying robust measures of the ecological
"health" of wetlands, and dynamic energy budget modeling that targets
mechanisms responsible for observed ecological change. The research is part
of a large, EPA-funded project involving over 20 scientists at UC Davis and
UCSB. The post-doc will work at Santa Barbara with Roger Nisbet, Allan
Stewart-Oaten, Bruce Kendall and Bill Murdoch.
Applicants should possess a PhD in mathematical biology, theoretical
ecology, biostatistics, or some related discipline, and have skills in both
dynamic modeling and statistics. The position is initially for 2 years.
Start date no later than 1 January 2002.
Applicants should submit a CV, a statement of research interests, and the
names and e-mail addresses of three referees to nisbet@lifesci.ucsb.edu.
Initial screening of applications will begin on 30 July, but applications
received after that date may be considered. AA/EOE.

Brian,
That's been my position from the beginning. I don't know whether global
warming is occurring (and neither does anyone else) and I support
environmentally friendly technologies etc. But it irritates me to no end
that supposedly educated people will support any issue that feels good to
them politically seemingly without regard for the truth (at least as we know
it).

In New Zealand, these comments would label you a "stirrer." they gave me a
good
laugh. while I don't necessarily agree with your thoughts on global
warming, I
am pained by the apparent tendency of scientists to feel a need to be
politically correct. "I don't know" or "I'm not sure" should always be a
reasonable opinion for a scientist. Brian

A Global Paleoclimate Observing System

A major obstacle to producing reliable predictions of climate change and
its impacts is a lack of data on time scales longer than the short
instrumental record. Recently initiated climate observation programs
will need to be continuously operated for at least 50 years before they
begin to provide information that is relevant to this problem. In
contrast, natural archives of past climate variability can provide
relevant information now.
Unfortunately, some of the most valuable paleoclimate archives are being
rapidly destroyed, largely as a result of human influences (see the
related News of the Week article in this issue by Koenig). We cannot
afford such an irreversible loss. The Past Global Changes (PAGES)
program of the International Geosphere-Biosphere Programme therefore
calls for scientists,
funding agencies, and institutional partners to establish immediately a
coordinated international Global Paleoclimate Observing System (GPOS) to
complement the Global Climate, Terrestrial, and Ocean Observing Systems
(GCOS, GTOS, and GOOS, respectively) that focus only on contemporary
observations.
An example of the loss of paleoarchives is the rapid retreat of alpine
glaciers in the tropics and temperate latitudes. Ice cores from such
glaciers have been used to reconstruct temperature, precipitation, and
atmospheric dust levels, and to provide records of changes in the
strength of the Asian monsoon and El Ni=F1o-Southern Oscillation (1). As
shown in the
figure, the total area of the summit glacier on Mt. Kilimanjaro
decreased by 82% between 1912 and 2000. Soon, the only information left
from the Kilimanjaro ice will be what is contained in the cores
extracted last year and stored in freezers at Ohio State University. The
situation on Kilimanjaro is not unique. Tropical warming is causing the
rapid retreat of ice caps and glaciers at high elevations in the tropics
and subtropics around the world (2). A second example of paleoarchives
that are being lost is the widespread damage to tropical corals.
Measurements in corals have been successfully used to reconstruct sea
surface temperature, salinity, and the surface circulation of the
tropical oceans for the past several hundred years, and for isolated
windows in the more distant past (3). Large living corals (more than 100
to 200 years old) suitable for climate reconstruction purposes are
relatively rare in most reef areas of the world. These corals are under
intense pressure from a myriad of localized stresses related to coastal
development and population pressure. In addition, widespread bleaching
and mortality of corals are occurring with increasing frequency as the
consequences of rising temperatures. Furthermore, studies indicate that
corals and other calcifying marine organisms are subject to geochemical
stresses from rising CO2 concentrations in seawater (4).
Another biological source of paleoclimate records are tree rings, which
have the potential to yield information on many aspects of tropical
climate, from the Asian monsoon and El Ni=F1o to the factors controlling
the storage of carbon in tropical forests (5). The use of tree rings
from tropical trees is relatively new, but is moving into the phase
where continental-scale collections must be made and analyzed. Massive
felling of the commercially valuable timber of old-growth timber such as
teak raises the possibility that, by the time scientists are able to
sample them, many of the old trees containing the most valuable
information will already have been sent to the sawmills.
Paleoarchives provide a wealth of information about past variability of
the climate system relevant to future concerns. Thus, we call for an
internationally coordinated effort designed to rescue endangered natural
archives of past environmental variability and initiate large-scale
observational and experimental campaigns to investigate the processes
recorded in these natural archives.

Subject: reprints request
Dear Aquatic Ecologists
I am working in a project on phytoplankton distribution and biomass
in a hypertrophic reservoir. I would be greatly indebted to colleagues
who can send me reprints of their works on this subject. This would
be of great help to me. Thank you.

Subject: O3, CO2, CFCs and other greenhouse gases
Hi,
to the best of my knowledge
= ozone - the trouble is that one has to separate
tropospheric and stratospheric ozone.
- stratospheric O3 is most important for UV absorption
It is destroyed by CFC's
- tropospheric ozone is a greenhouse gas but
additionally really unpleasant and we would
prefer not to have it in higher concentrations.
= CFC's
- because of O3 destruction they not welcome in the
stratosphere
- moreover, however, they are not welcome in the
troposphere either, because
. they get to the stratosphere some time
. they are a very potent greenhouse gas. About
14000 times more effective than CO2.
BUT and this is important:
because of their very low concentration CFCs play
only a minor role as greenhouse gas which is nevertheless
significant because of their "high greenhouse gas potential".
However, their production is heavily regulated and will
probably cease some time.
For the relative contributions of the different atmospheric
components to the radiative forcing in 2000 over the one of
1750 see the:
IPPC TAR 3 Summary for policy makers page 8 accessible from
http://www.ipcc.ch/
See also p. 7 for more in depth info.
So: Even though O3 and CFCs are important as greenhouse gases
their importance will hopefully decrease strongly in the next
two decades as we clean up pollution and limit the use of
halocarbons. O3 is only short lived in the troposphere
partially because of its habit to damage to organic tissue...
The more significant problem is CO2 and CH4 because
- CO2 is very long lived in the atmosphere and CH4 is about four
times as effective as CO2 as greenhouse gas even though is
transformed to CO2 after a while (using OH radicals)
- fossil fuels are much more important to our economies than
CFCs ...
CH4 and N2O can probably be limited somewhat more by improving
farming practices (rice paddies, cows, and fertilizer volotisation...)
This brings us back to fossil fuel use - no excuses.
The following comments are not specifically meant to apply
to Prof. Fred S. Singer.
It is therefore very naive not suppose a conflict of interest
in a person being funded by Western Fuels or EXXON.
Since climate change is now highly politicised it is also very
naive to assume there can be any scientific high visible statements
for or against climate change which would not be followed by
press coverage. In the case of pro climate change statements
one has moreover to expect some comment of the right wing pro fossil
fuel usage camp which aims at diminishing the scientific or personal
credibility of the persons making the statements. One might
argue that the pro greenhouse camp does this too, but I strongly
believe that there are significant differences. As far as I have
seen the pro greenhouse camp limits itself to pointing out the
scientific merits of the people.
Whereas the anti greenhouse camp actively tries to destroy the
careers and the livelihood of scientists. They did succeed once
in a while.
All this calmed down a little but it is very frustrating to see
that people like Prof. S. Fred Singer can still attack so
much attention with statements that are scientifically out of
date by a couple of years.
About that I allegedly attacked Prof. Fred S. Singer with the
statement - from my e-mail:
"Prof. S. Fred Singer, professor emeritus of environmental sciences at the
University of Virginia and a former director of the U.S. Weather Satellite
Service.
is known to take a very opinionated (according to his own words)
anti greenhouse position."
personally -
from Brad Robbins's e-mail:
"I find it interesting that the first thing each of you did was
attack him on a personal level..."
This was not a personal comment nor did I relate my opinion.
This was a statement he made himself while opening a
talk in Stanford I happened to attend. I object strongly
to your try, Brad Robbins, to put words into my mouth.
I will not give my personal opinion about Prof. Fred S. Singer
in any public forum.
Oh, by the way I don't have any funding right now :-)
'hope this helps.
Cheers,
Joerg

Dear listers,
I want to know, should I have any English fluency certification such as TOEF
,
GRE or IELTS for a postdoctoral position in English countries?
Thanks in advance!
