The primary objective of this investigation was to study the ecological life history of the mayfly Baetisca berneri Tarter and Kirchner in Laurel Fork, Mingo Co., West Virginia. Many authors, including Say (1839), Traver (1931), Needham et al. (1935), Berner ( I940, 1955 ), Edmunds (I 960), Schneider and Berner (1963), Pescador and Peters (1971, 1974), Lehmkuhl (1972), Tarter and Kirchner (1978) and Chaffee and Tarter (1979), have reported studies on the taxonomy and ecology of the genus Baetisca.

Fernow Experimental Forest

We examined the abundance, life history, and production of the stonefliesPeltoperla arcuataandTallaperla maria(Plecoptera: Peltoperlidae) in four forested headwater streams at the Fernow Experimental Forest, Tucker County, West Virginia.Peltoperla arcuatawas most abundant in the smallest watersheds (<100 ha), and was present at all sites.Tallaperla mariawas most abundant in watersheds >200 hectares (ha), was restricted to sites with a base-flow alkalinity of >2 mg L-1CaCO3, and was the dominant peltoperlid only at sites with an alkalinity >15 mg L-1. We conclude that water chemistry overrides stream size as a determinant of species-specific distribution of Fernow peltoperlids. Both taxa had semi-voltine life cycles with an 18-month naiadal period following a 6-month egg diapause. Emergence was during May-July for both species.Peltoperla arcuatahad about 15 instars;T. mariahad about 14 instars. Peltoperlid production was highest (509 mg m-2y-1) in a 128 ha watershed where onlyP. arcuatawas collected;P. arcuataproduction was lowest (17 mg m-2y-1) in a 4th order stream (1536 ha).Taltaperla mariaproduction was highest (271 m-2y-1) in a 257 ha watershed partially underlain by limestone. Production across streams was higher forP. arcuata(205 mg m-2y-1) than forT. maria(91 mg m-2y-1).

Museum specimens of five species of fossorial snakes collected in West Virginia during 1930–2000 were examined to determine monthly incidence of capture, adult body sizes, reproductive cycle, and clutch characteristics. Captures occurred over the shortest time in the year in the Eastern Earthsnake (Virginia valeriae valeriae) and Northern Red-bellied Snake (Storeria occipitomaculata occipitomaculata) and were longest in the Northern Brownsnake (S. dekayi dekayi). Male gonadal cycle conformed to the temperate pattern, whereas that of females tended towards a tropical pattern. Incidence of females nearing oviposition or parturition was highest during June–July for all species, and length of their reproductive seasons were generally in keeping with those of northerly populations of the respective species. Mean clutch sizes were largest in the Northern Brownsnake (mean = 20.5) and smallest in the single oviparous snake, the Eastern Wormsnake (mean = 2.8). Adult body sizes were similar to respective populations elsewhere within their ranges. The Mountain Earth Snake (V. pulchra) was the least represented species in this study. A meaningful degree of predictability existed in the life history traits examined in our study as they related to geographic trends of this Allegheny snake assemblage.
