The a priori null hypotheses that responses to donor, orangethroat darter Etheostoma spectabile , johnny darter Etheostoma nigrum , logperch Percina caprodes , slenderhead darter Percina phoxocephala and blackside darter Percina maculata , extracts would be absent in the three test species, orangethroat darter, johnny darter and logperch, was rejected. This was because orangethroat and johnny darter responded with decreased activity to skin extracts derived from conspecifics and from other members of the assemblage. In contrast, logperch were notable by their lack of a detectable response to any species. Similarities and differences in habitat utilization are seen as a possible basis for these responses.
