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.

Natural History Of The Red-Spotted Newt, Notophthalmus Viridescens Viridescens (Rafinesque), In West Virginia, Jennifer M. Piascik

Theses, Dissertations and Capstones

Many studies have been conducted on Notophthalmus viridescens viridescens but none have occurred in West Virginia. There are variations in the life history of newts depending on location.

The population structure can be divided into four classes: egg, larvae, eft, and adult. Eggs at Shoals were deposited in mid-May and larvae were present from mid-June to early September. Larvae began to transform at an approximate total length of 32.8 mm. Red …
