South Fork of Sand Lick Creek, Logan County, West Virginia, drains an abandoned coal strip mine which had exploited Pottsville series coalbeds (Pennsylvania strata). These strata outcrop throughout southwestern West Virginia. North Fork watershed is relatively unchanged, save a small roadcut throughout. South Fork benthic community had not recovered although mining activity had ceased about 20 years earlier. Benthic communities were analyzed with detrended correspondence analysis (DCA). Family Chironomidae predominated South Fork benthic community throughout the study. North Fork’s benthic community had as major contributors acid resistant caddisfly family Hydropsychidae, mayfly family Baetidae, and stonefly families Perlodidae and Nemouridae. Family …

Ecology And Population Demography Of The Hellbender, Cryptobranchus Alleganiensis, In West Virginia, W. Jeffrey Humphries

Using mark-recapture, I studied the population demography and habitat use of the hellbender, Cryptobranchus alleganiensis, in the West Fork of the Greenbrier River, Pocahontas County, West Virginia. Eighteen nocturnal surveys were conducted between April and October, 1998, during which 29 hellbenders were implanted with permanent tags. Male to female sex ratio was 1.06:1. Hellbenders were sexually dimorphic, as females were significantly longer and heavier than males. Total lengths for all captured animals ranged from 29.5 - 56.5 cm and mass ranged from 150.0 - 905.8 g. Seasonal linear movements for 12 individuals ranged from 0.8 - 70.2 m (mean …
