Natural History Of The Four-Toed Salamander, Hemidactylium Scutatum, In West Virginia, Sandra L. Kilpatrick
Natural History Of The Four-Toed Salamander, Hemidactylium Scutatum, In West Virginia, Sandra L. Kilpatrick
Theses, Dissertations and Capstones
A 2-year study was conducted to determine the reproductive and nesting habits, embryonic and larval development, and tolerance to acid conditions of Hemidactylium scutatum in West Virginia. Five study sites located in or adjacent to the Otter Creek National Wilderness Area, Monongahela National Forest, Randolph County, West Virginia, were monitored to determine nesting habits and length of incubation and larval periods in Hemidactylium Time of breeding was determined by spermatogenic wave analysis and time of egg deposition was determined by examination of ovarian follicles and field observations of gravid females migrating to nest sites. Breeding occurred in autumn and again …
Ecological Life History Of Crangonyx Pseudogracilis Bousfield (Crustacea: Amphipoda) In The Green Bottom Wildlife Management Area, Cabell County, West Virginia, Andrea Leigh Henry
Ecological Life History Of Crangonyx Pseudogracilis Bousfield (Crustacea: Amphipoda) In The Green Bottom Wildlife Management Area, Cabell County, West Virginia, Andrea Leigh Henry
Theses, Dissertations and Capstones
Although the genus Crangonyx has been studied in the Appalachian area, most of this work has concentrated on subterranean species. A Crangonyx pseudogracilis population from the Green Bottom Wildlife Management Area (GBWMA), Cabell County, West Virginia was sampled weekly from March 1995 through July 1996 to investigate the ecological life history of the amphipod. A total of 1508 amphipods were collected. Amphipods were present in the study sites from November through July, at which time they migrated to deeper waters. Crangonyx pseudogracilis had a one year life cycle and bred from November to May. Adult amphipods began to die off …
An Ecological Study Of Shale Barren Rock Cress (Arabis Serotina Steele) At Little Fork Shale Barren, Pendleton County, West Virginia, Robert J. Jarrett
An Ecological Study Of Shale Barren Rock Cress (Arabis Serotina Steele) At Little Fork Shale Barren, Pendleton County, West Virginia, Robert J. Jarrett
Theses, Dissertations and Capstones
Shale Barren Rock Cress (Arabis serotina Steele) was listed as a federally endangered species by the U.S. Fish and Wildlife Service in August 1989. As part of a cooperative agreement between the West Virginia Natural Heritage Program and the U.S. Navy, research was conducted in 1994 and 1995 at Little Fork Shale Barren (LFSB) to provide baseline information on the population dynamics of A. serotina and to study the vegetation and physical parameters associated with this shale barren community. Soil samples and plant community data were collected from 40 1-m2 circular plots for herbaceous vegetation and six 0.02-ha …
