Investigators: Professor John Avise (E-mail: javise@uga.edu ), Dr. Brady Porter (E-mail: porter92@uga.edu ) and Anthony Fiumera (E-mail: acf10@psu.edu ). Institution: Department of Genetics, University of Georgia, Athens, GA. 30602 USA. Project: We are using microsatellite DNA markers to quantify multiple aspects of the genetic structure of a population of mottled sculpin (Cottus bairdi) inhabiting Shope Fork (Coweeta drainage, western North Carolina, USA). At present we are examining: 1) the mating system, 2) reproductive success, 3) genotype X age and growth characteristics, 4) spatial distributions of genotypes within the stream, and (Photo of the Avise group scoring a gel.) 5) reproductive success versus nest site characteristics.

Investigator: Professor Sheryl Coombs (Web site: http://www.parmly.luc.edu/parmly/Coombs.html ). Institution: Parmly Hearing Institute, Loyola University of Chicago, Chicago IL 60626. USA. Project: We are examining the role of the acoustico-lateralis system in rheotaxis and prey capture behavior in mottled sculpin (Cottus bairdi).

Investigators: Drs. Gael Grenouillet (Gael.Grenouillet@univ-lyon1.fr ) & Didier Pont (dpont@biomserv.univ-lyon1.fr ) . Institution: Laboratoire de Ecologie des Hydrosystemes fluviaux, Universite Lyon 1, Lyon France. Project: We are examining the role of density-dependence in the regulation of Cottus populations, and examining the role of prey availability on foraging site choice by blackbanded darters (Percina nigrofasciata).

Investigator: Dr. Brenda Rashleigh (E-mail: rashleigh.brenda@epamail.epa.gov ). Institution: US Environmental Protection Agency, 960 College Station Rd, Athens, GA. 30605 USA. Project: We have constructed an individual-based simulation model which describes the effects of hydrologic variation, prey abundance, and intraspecific competition on population dynamics of mottled sculpin (Cottus bairdi) in a southern Appalachian stream (Ball Creek, western North Carolina, USA).

Investigator: Professor Daniel Promislow (E-mail: promislo@uga.edu). Institution: Department of Genetics, University of Georgia, Athens, GA. 30602 USA. Project: We are quantifying whether a trade-off is present in fecundity versus egg size in mottled sculpin (Cottus bairdi) inhabiting Shope Fork (Coweeta drainage, western North Carolina, USA).
