Dr. James Bandoli:

• Parental Investment in Spottail Darters
  Field and laboratory investigations into patterns of energy investment by nest-guarding male spottail darters (right), a local stream fish that practices resource-defense polygyny.
• Teaching Evolution in Public High Schools
  A survey of students in Ohio (weak standards) and Indiana (strong standards) to compare the time given to evolution in introductory biology courses in public high schools and the degree to which high school teachers emphasize evolution as an explanation for the diversity of life.

Dr. Cindy DeLoney-Marino:

Research interests
Characterizing the chemotactic behavior of the bioluminescent marine bacterium Vibrio fischeri. I aim to determine if this microbial symbiont is chemotactically attracted to its squid host, Euprymna scolopes, and whether or not such an attraction is required for the bacteria to initially colonize the squid light organ.

Dr. R. Brent Summers:

• Bioassessment of Blue River, IN.
  In the summer and fall of 2006 I, along with several undergraduate research students will be conducting a bioassessment of the Blue River in Harrison, Washington, and Clark Counties of Indiana. We will be specifically sampling fish and macroinvertebrate communities to look for long term trends in water quality and watershed health.

• Physiological Ecology of the Indiana Crayfish (Orconectes indianensis).
  I currently have two undergraduate students who are working a project to investigate the physiological ecology of the Threatened Indiana Crayfish (Orconectes indianensis). In particular they are measuring the respiratory rates of crayfish under varying physiological stressors such as increased temperatures, turbidities, and salinities.

• Effects of a Dam Re-operation on Green River, KY.
  I also have a continuing project to investigate the effects of a new dam re-operation agreement between the Army Corps of Engineers (on the Green River in central Kentucky) and the Kentucky Chapter of the Nature Conservancy. In the past several years I have completed several studies investigating the secondary production of several macroinvertebrates in Green river below the dam.
  
  I currently have a student who in the spring of 2006 is developing a revised method for extracting and characterizing lipid fractions in key macroinvertebrates found in Green River. From this we will implement a study to determine the effects of dam re-operation on energy reserves and bioenergetics of several key species of macroinvertebrates in the Green River.
