Frank M. Wilhelm
Laboratory rearing
of the federally listed Illinois cave amphipod.
Goals:
 Restoration of a small pond impacted
by a
brine
spill from
oil
and gas development.
Goals:
-
map bathymetry
of pond
- calculate mass of chloride in monimolimnion
- install aerators to destratify the
pond
and remove meromixis
- monitor whole lake chloride
concen
- monitor plankton and benthic
communities to examine potential impacts of chloride mixing
Bathymetric mapping of lakes in the Shawnee National Forest
Goals:
- map bathymetry of a variety of lakes
in the Shawnee National Forest to estimate sedimentation rates and
provide baseline for water level management
Aquatic Community
Inventory of Wells and Cisterns in the
Shawnee
National Forest (SNF)
Goals:
- locate and sample the water
chemistry and biological community in old homestead wells across the
Shawnee National Forest
- set up shallow groundwater
monitoring
network across the SNF using these old wells
- access hard to sample groundwater
fauna
 Life history, reproductive strategy
and growth of Palaemonetes kadiakensis in a southern Illinois
Lake.
Goals:
- determine life cycle length and
general life history characteristics
- compare inter-annual growth rates
and reproductive strategies
- understand seasonal lipid dynamics
- potentially culture as source of
essential fatty acids for inclusion in aquaculture feeds
 Long-term restoration of Campus Lake
Goals:
- reduce nutrient input to Campus Lake
- reduce/prevent noxious algal blooms
- increase aesthetic aspects of lake,
install handicapped fishing pier
- install aerators to reduce hypolimnetic
oxygen depletion
 Ecology and
Seasonal Lipid Dynamics of
Amphipods in Southern Illinois
Goals:
- identify amphipod
species in lakes of southern Illinois
- determine their
ecology, life history and reproductive strategies
- use this information
to predict fate of aquatic invertebrates with
rising water temperatures associated with
climatic warming
- study seasonal lipid
dynamics by measuring total lipids and selected
fatty acids
- identify amphipod
species with fatty acid profiles suitable for the
culture of food fish
 Seasonal
Physiological Requirements of Cave Amphipods in Illinois
In collaboration with Steve J. Taylor (Principal Investigator), Center for
Biodiversity, Illinois Natural History Survey
Goals:
- examine the ecology
of amphipods in caves of Illinois including the
federally endangered Illinois Cave Amphipod (Gammarus
acherondytes)
- provide basic
ecological information on G. acherondytes
to aid managers in its recovery
- use
computer-controlled electrodes to measure the
oxygen consumption of cave amphipods
