[ECOLOG-L] Volunteer Field Assistant Needed - Blandy Experimental Farm

2008-04-09 Thread Kevin J Barry
I am a Ph.D. student at the University of Maryland looking for an 
undergraduate interested in research experience with invasive plant 
species and disturbance in plant communities.  This is a great 
opportunity to spend the summer outdoors and gain valuable research 
experience.  I am looking for someone who enjoys nature and is willing 
and able to work outside in the summer.  I typically work at my field 
station during the week and return home to DC for the weekend.  Room to 
live and work, utilities, and most meals are paid for.  The position 
will involve assisting me in making measurements on native and invasive 
plants grown in experimental communities.  You will learn to identify 
native and invasive plant species, how to design and run a large-scale 
field experiment, and will have the opportunity to design and work on 
your own (related) project.  The field location is near Winchester, 
Virginia (approx. 70 miles west of DC) at the Blandy Experimental Farm, 
a research station that has a community of both graduate students and 
~15 undergraduates working there each summer.  The large number of 
students provides for a lively community.  This is also where the State 
Arboretum of Virginia is located, and many popular hiking trails 
(including the Allegheny trail) and wineries are nearby.  This is a 
great chance to work and have fun outdoors in the countryside of the 
Shenandoah Valley.  This is a volunteer position, and there may be an 
option to receive credit, if your program allows it.  The position can 
last all or part of the summer.  E-mail Kevin Barry at [EMAIL PROTECTED]

[ECOLOG-L] Looking for ecological statistics training courses (focused on streams in the northeast preferably)

2008-04-09 Thread Chalfant, Brian
Hi all -

I am looking for any ecological statistics/data analysis type trainings
available concerning stream ecology in the northeastern United States.
I am interested in courses that go beyond basic descriptive statistics
and would ideally like to find something that covers multivariate
analysis techniques applied to benthic macroinvertebrate data.  It would
be great to find something that covers relationships among measures of
biological integrity, geomorphic structuring variables and
environmental/anthropogenic stressors.

I found one course available through the U.S. Fish and Wildlife Service
National Conservation Training Center in Shepherdstown, West Virginia
that sounds up my alley
(http://training.fws.gov/branchsites/CSP/Course_descriptions/CSP2321.htm
), but I have a schedule conflict that prevents me from attending the
next offering of this course (July 2008) and I need to find something
offered before October 2008 (otherwise my training money will
disappear!).  Any leads would be greatly appreciated.

Re: [ECOLOG-L] wetland acreage

2008-04-09 Thread Gilmore, Robert
A couple of questions come to mind.
 
Is origin more important than the functions/values of these habitats?
Is characterizing such wetlands as artificial simply a convenience to
make it easier to justify their loss?  Does the ecological
function/value of a restored stream outweigh the ecological
function/value of the wetlands being lost?

2008-04-09 Thread Scott R. McWilliams
Ph.D. assistantship in Avian Physiological Ecology (beginning mid-August
2008) on an NSF-funded project that focuses on how dietary fatty acids and
antioxidants affect diet choices, metabolism of fatty acids, and exercise
performance of songbirds. The work includes (a) measuring fatty acid
composition of diets and depot fat in migrating songbirds, (b) conducting
experiments with wild-caught songbirds that focus on how dietary
antioxidants influence diet choice and metabolism of fatty acids, and (c)
conducting experiments with flying birds in a windtunnel that focus on how
fatty acid composition and antioxidants affect exercise performance of
songbirds.

Most field work will be conducted on Block Island (ca. 15 km off the
mainland), Rhode Island. Captive animal facilities are on the University of
Rhode Island's main campus in Kingston. Windtunnel experiments with flying
birds will be conducted at the Max Planck Institute for Ornithology in
Germany. The PhD candidate will be resident at the Max Planck Institute for
Ornithology in Germany from Aug-Dec 2008 while conducting research, and then
at University of Rhode Island thereafter with other planned experiments in
Germany during 2010.

Only hard-working, motivated, intelligent, good-natured persons interested
in birds need apply.  Applicants must have at least a 3.2 GPA and must have
taken the GRE.  Field experience with passerine birds and experience in
physiological ecology is required.  Experience with captive birds and
standard laboratory analysis techniques is a big plus. Excellent writing and
oral communication skills are required. Stipends are approx. $20,000/yr (50%
RA  TA for first two years, 100% RA thereafter) and tuition is paid.

To apply submit the following: a letter stating your qualifications and
research interests, resume or CV, college transcripts, GRE scores, and 3
letters of reference by no later than 10 May 2008 (early application is
encouraged!) to Dr. Scott R. McWilliams, Dept. Natural Resources Science,

Jan, Neil, and Forum:

Thanks.  It's good to know about the project. 

While elevation is certainly one gradient (and latitude is another), I 
was thinking more of those that might make up those kinds of gradients. 

Temperature, pH, and humidity, for example, are just some of the more 
precisely quantifiable gradients that might be part of a measurable 
diagram of species, ecotype, or other category of life-form that would, 
if sufficiently well-done, be a predictor of both life-form and 
habitat.  Ricklefs, for example, suggested such a diagram, if I recall 
correctly, in his 2nd edition of Ecology.  I was hoping to be brought 
up to date on what might have been done with this concept since that 
publication.  Perhaps your research involves such measures, or if others 
might know of publications which have further refined the concept since 
those days . . .

Re: [ECOLOG-L] wetland acreage

2008-04-09 Thread Wayne Tyson
Lots. 

When this subject comes up, I usually think of the time I found vernal 
pool species in some tire-ruts.  Environments change, and organisms 
change accordingly.  Humans, being impatient beings, often make changes 
so quickly that organisms can't adjust quickly enough to avoid 
extinction.  Such changes can be on the scale of a tire-track, a 
bulldozer, a footfall, or multiples thereof, in terms of time, 
proportion, area, extent and such, and comets and volcanoes, not to 
mention beetles and elephants, can have their effects too.  But if 
artificial landscapes (literally, land+scrape) require the hand of 
humans (or, say, beavers) for their existence . . .

Re: [ECOLOG-L] wetland acreage

2008-04-09 Thread Sharif Branham
Hello Andy,
 
I think the question should be about the quality of the wetlands that are being 
replaced. Wetlands that are created as a result of roads or other engineered 
surfaces are not equal to a natural wetland as far as habitat value is 
concerned. One could do an analysis of the wetland that is to be displaced by 
breaching the dam to see if the quality of the habitat that will be lost is 
equal, less than or greater than the habitat that will be enhanced by breaching 
the dam.  You could consider the quantity and diversity of the species that 
benefit from each habitat type. You could even look at ecological services 
being provided by the wetlands versus what will be gained by breaching the dam. 
 I hope that helps you get at the essence of the argument.
