Graduate Assistantship and Post-Doctoral Researcher Opportunities
(December 2003)
The following opportunities are available in the laboratory of Professor
Gary D. Grossman, Warnell School of Forest Resources, University of
Georgia, www.arches.uga.edu/~grossman .
Two ^Ö four PhD assistantships available (two immediately) although the
starting date could be as late as next fall. The assistantships pay
between $16,500 ^Ö $18,000 US annually and come with a tuition waiver.
The descriptions of both of these projects are short, but both projects
have substantial room and funding for the student to develop their own
ideas involving the stated general topics.
1) Via both field and lab experiments the student will assess the
effects of stocked rainbow trout on native non-game fishes in Southern
Appalachian mountain streams. This study will focus on both
population-level and microhabitat-level effects. Funding is available
for 4 years.
2) This project will determine the effects of turbidity on foraging
success and ultimately, population growth of native water-column fishes
in Southern Appalachian streams. We will measure the effects of
turbidity on both reactive distances and foraging success of several
native drift-feeders. There also is the possibility of working with an
invasive species and attempting to determine if its ability to tolerate
high turbidity will facilitate its establishment in new rivers.
Finally, the ultimate goal of this project will be to couple the
foraging success information with a population model to predict how
turbidity will ultimately affect fish abundance. For information about
basic approaches to be used in this study see (Barrett, J. D., G. D.
Grossman, and J. Rosenfeld. 1992. Turbidity induced changes in reactive
distance in rainbow trout (Oncorhynchus mykiss). Trans. Am. Fish. Soc.
121:437-443 and Grossman, G.D., Rincon, P. A., Farr, M.D., and R. E.
Ratajczak. 2002. A new optimal foraging model predicts habitat use by
drift-feeding stream minnows. Ecol. Freshwat. Fish 11:2-10).
3) MSc with potential for PhD ^Ö this project will utilize a
patch-fitness based approach to assess microhabitat choice in a benthic
stream fish (probably a darter). We will quantify patch quality and
fitness characteristics of fishes in these patches (i.e., residence
times, giving up densities, growth, survivorship, etc.). Population
level linkages are possible via removal experiments or artificial
manipulation of patch quality.
4) Pending funding approval ^Ö PhD assistantship to examine the role of
large woody debris on flow dynamics and foraging success in several
Texas riverine fishes. The basic approach is described in the turbidity
project above except that we will not be looking at the effects of
turbidity but we will be examining the small & large-scale hydrologic
impacts of large woody debris on optimal velocities for fishes in
rivers. See below for a broader description of the project.
5) Potential MSc opportunities ^Ö there is a possibility for
assistantships via the EPA NNEMS Fellowship Program. This would require
working together to write a short proposal that deals with some aspect
of basic/applied ecology. Potential areas include: 1) landscape
approaches to aquatic systems, 2) effects of turbidity on aquatic
systems, 3) invasive species issues. The applicants that I^Òve sponsored
have had a high success rate on these fellowships. Applications are due
January 24 2004, so if you^Òre interested please contact me ASAP.
POST-DOCTORAL OPPORTUNITIES
1) We are looking for a post-doc to start summer 2004 to coordinate
efforts of a three laboratory - one agency research program
investigating the physical and biological effects of large woody debris
on riverine fish habitat in Texas. Funding for this position is
pending. The research program involves Dr. Ben Hodges (fluid dynamics
modeler, University of Texas, hodges@mail.utexas.edu), Dr. Heidi Nepf
(fluid dynamics experimentalist, MIT, hmnepf@mit.edu), Dr. Barney Austin
(Chief, Surface Water Section, Texas Water Development Board,
Barney.Austin@twdb.state.tx.us ) and myself. The post-doc will be based
in my laboratory and will spend time working with the other PI^Òs. The
post-doc will benefit from having a biological background and should be
interested in gaining experience with biological applications of
numerical modeling and experimental fluid dynamics. Starting salary is
$37,000 with health benefits and annual increments. The position will
last for 4 years.
2) I am currently interested in discussing post-doc opportunities with
students who have interests in landscape approaches to habitat selection
and population dynamics in southeastern streams. Included in this
general topic is the application of multifaceted approaches to
prediction of the spread of invasive fis
