A Distributional And Taxonomic Study Of The Adults Of The Family Hydropsychidae (Trichoptera) In West Virginia, Toni Ann Phillips Jan 1982

A Distributional And Taxonomic Study Of The Adults Of The Family Hydropsychidae (Trichoptera) In West Virginia, Toni Ann Phillips

Theses, Dissertations and Capstones

A survey of the adult Hydropsychiclae revealed 39 species, 14 of which were state records. The adult hydropsychids were collected from various locations throughout West Virginia. The most common species Hydropsychidae were Hydropsyche morosa, H. sparna, Cheumatopsyche analis, C. campyla, and Diplectrona modesta. Most of the species did not appear to be limited to any one particular drainage basin. Several species exhibited a preference for stream order (headwaters, middlereaches, large rivers). Aphropsyche monticola, Parapsyche apicalis, Cheumatopsvche wrighti, C, gyra, and Hydropsyche alhedra preferred the fast-flowing headwater streams in the higher elevations of the state. Macrostemum zebratum, Potomyia flava, Hydropsyche phalerata, …


The Influence Of Habitat Variation On The Morphology And Physiology Of Plethodon Wehrlei (Fowler And Dunn) In West Virginia, Sharon Kay Gross Jan 1982

The Influence Of Habitat Variation On The Morphology And Physiology Of Plethodon Wehrlei (Fowler And Dunn) In West Virginia, Sharon Kay Gross

Theses, Dissertations and Capstones

High elevation, low elevation and cave populations of Plethodon wehrlei (Fowler and Dunn) in West Virginia were compared to determine the influence of habitat variation on morphology and physiology. Discriminant analysis of 14 external morphological characters and 11 skeletal characters revealed a similar morphology for the three populations. Comparisons of critical thermal maxima showed a positive correlation to habitat temperature. Dehydration studies revealed that the high elevation population was more resistant and tolerant to water loss than the cave and low elevation populations.
