Sa. Welsh et Sa. Perry, HABITAT PARTITIONING IN A COMMUNITY OF DARTERS IN THE ELK RIVER, WEST-VIRGINIA, Environmental biology of fishes, 51(4), 1998, pp. 411-419
Microhabitat use and habitat partitioning for 10 darter species (Perci
dae: Etheostomatini) were studied by direct observation (snorkeling) a
t five sites in the Elk River drainage, Sl;est Virginia, U.S.A. We use
d canonical discriminant analysis and univariate tests to determine mi
crohabitat variables that were important in segregating species. Darte
r species were segregated by-depth. substrate size, and water velocity
. In addition, Percina typically occurred in tile water column. wherea
s species of Etheostoma were benthic and segregated by occurring under
, between, and on top of rocks.
