Changes In Small Mammal Community Attributes Associated With Increasing Pine Stand Age In Managed Pine Plantations In Southeastern Virginia, James Douglas Dolan Oct 1998

Changes In Small Mammal Community Attributes Associated With Increasing Pine Stand Age In Managed Pine Plantations In Southeastern Virginia, James Douglas Dolan

Biological Sciences Theses & Dissertations

Loblolly pine plantations were examined at different ages to identify small mammal community attributes in relation to the succession of the plant community. Forest floor and understory plant communities were characterized. Small mammals were collected by Fitch (live) traps and pitfall traps in four age classes during five seasons of study. Fitch live traps and pitfall traps were used in conjunction with one another to obtain the most accurate depiction of the small mammal community. Fitch traps accounted for 65 % of small mammal captures and 7 of 9 species captured. Small mammal abundance and biomass declined with increasing stand …


Seasonal Changes In Brown Fat And Pelage In Southern Short-Tailed Shrews, Elisa M. Dew, Keith A. Carson, Robert K. Rose Jan 1998

Seasonal Changes In Brown Fat And Pelage In Southern Short-Tailed Shrews, Elisa M. Dew, Keith A. Carson, Robert K. Rose

Biological Sciences Faculty Publications

We examined cellular changes in interscapular brown adipose tissue and pelage characteristics in Blarina carolinensis collected throughout the year in eastern Virginia. Cellular volume occupied by mitochondria and maximum mitochondrial size were significantly greater in the brown adipose tissue of winter shrews than in summer shrews. Lipid droplets occupied greater volume and were larger in shrews in summer than winter shrews. There were no seasonal differences in hair density; Type I and Type II guard hairs were significantly longer in winter than summer by a factor of 1.3. Woolly hairs were 1.2 times longer in winter than summer, a non-significant …


Cladistic Analysis Of 37 Mediterranean Bogidiellidae (Amphipoda), Including Bogidiella Arista, New Species, From Turkey, Stefan Koenemann, Ronald Vonk, Frederick R. Schram Jan 1998

Cladistic Analysis Of 37 Mediterranean Bogidiellidae (Amphipoda), Including Bogidiella Arista, New Species, From Turkey, Stefan Koenemann, Ronald Vonk, Frederick R. Schram

Biological Sciences Faculty Publications

A new subterranean amphipod species, Bogidiella (Medigidiella) arista, found in the mesopsam mic ground waters of southern Anatolia, Turkey, is described, together with Bogidiella (Bogidiella) calicali Karaman, the latter being recorded for the first time in the eastern Mediterranean. A cladistic analysis of 37 Mediterranean species of the family Bogidiellidae is performed, using 4 species from the Canary Islands as an outgroup. Alternatively, 2 cladistic software packages, PAUP 3.1.1 and HENNIG86, are employed to calculate consensus trees of minimal length. The resulting trees show more or less identical robust clades, characterizing a central, a central-eastern, …


Ecology Of The Eastern Cottonmouth (Agkistrodon P. Piscivorus) At Back Bay National Wildlife Refuge: A Comparative Study Of Natural And Anthropogenic Marsh Habitats, Chad Lee Cross Jan 1998

Ecology Of The Eastern Cottonmouth (Agkistrodon P. Piscivorus) At Back Bay National Wildlife Refuge: A Comparative Study Of Natural And Anthropogenic Marsh Habitats, Chad Lee Cross

Biological Sciences Theses & Dissertations

Mark-recapture sampling and radiotelemetry were used to investigate populations of the eastern cottonmouth, Agkistrodon p. piscivorus, in both natural and anthropogenic marsh habitats at Back Bay National Wildlife Refuge (BBNWR), Virginia Beach, Virginia from autumn 1995 to late spring 1998. Mark-recapture subjects were captured, marked by ventral scale-clipping, and released back into the population. A modified Schnabel Census estimator was used to estimate population sizes and corresponding densities in both marsh systems based on a total of 244 captures of 222 individuals. Most snakes were found >0.05 in from water, but it was apparent that proximity to water played …
