Foundational Checklist Of The Amphibians Of Wise County, Virginia, Sarah R.A. Davidson, David L. Chambers Oct 2010

Foundational Checklist Of The Amphibians Of Wise County, Virginia, Sarah R.A. Davidson, David L. Chambers

Virginia Journal of Science

The Appalachian Mountains are arguably home to the highest degree of amphibian diversity in the world, particularly caudate (salamander) biodiversity. Despite the high degree of amphibian endemism in the Appalachians, several regions remain unsurveyed for amphibian species. In addition to this knowledge gap, we are in the midst of alarming amphibian biodiversity loss. Thus, it is of the utmost importance to bridge this knowledge gap by conducting surveys before some of these amphibian species are lost. We surveyed Wise County (previously unsurveyed county in the Appalachian Mountains with no records existing in the primary literature) over two years to assess …


Garlic As An Alternative Anthelmintic In Sheep, A. Curry, B. D. Whitaker Apr 2010

Garlic As An Alternative Anthelmintic In Sheep, A. Curry, B. D. Whitaker

Virginia Journal of Science

An increase in the anthelmintic resistance of parasites in small ruminants and a push towards non-chemical farming has led researchers to search for alternative forms of anthelmintics. The efficacy of treating sheep by using natural garlic extract with respect to changes in weight, fecal egg counts (FEC), and packed cell volume (PCV) was investigated. Sheep were treated every 4 weeks for 8 weeks with saline (control) Ivermectin, or natural garlic extract and samples were collected weekly to determine FEC and PCV. Sheep were weighed at the time of sample collection to determine weight change. There were no significant differences between …

A Habitat Model For The Detection Of Two-Lined Salamanders At C. F. Phelps Wildlife Management Area, Fauquier And Culpeper Counties, Virginia, Jay Mcghee, Michael D. Killian Jan 2010

A Habitat Model For The Detection Of Two-Lined Salamanders At C. F. Phelps Wildlife Management Area, Fauquier And Culpeper Counties, Virginia, Jay Mcghee, Michael D. Killian

Virginia Journal of Science

Aquatic salamanders represent an important component of Virginia river watersheds, but despite potential declines, few specifics are known about their habitat preferences. We surveyed the habitats of the northern two-lined salamander and collected data on an array of habitat variables associated with the species. We used a logistic regression analysis to develop a model predicting its presence or absence for a given 50m-transect. Our final model incorporated the variation in stream depth and direction of stream flow and accounted for 25% of the variation in our data. We conclude that stream depth variation is an important feature of salamander habitat …


Functional Feeding Groups, Species Richness, And Spatial Distributions Of Fishes In Rocky And Sandy Beach Habitats Of St. John, U.S. Virgin Islands, Eugene G. Maurakis, George E. Maurakis, Demetri E. Maurakis Jan 2010

Functional Feeding Groups, Species Richness, And Spatial Distributions Of Fishes In Rocky And Sandy Beach Habitats Of St. John, U.S. Virgin Islands, Eugene G. Maurakis, George E. Maurakis, Demetri E. Maurakis

Virginia Journal of Science

Objectives were to identify and compare fish species richness, functional feeding group richness and diversity, and delineate distributions of fishes at rocky and sandy beach habitats at St. John, U.S. Virgin Islands. Visual observations using snorkel and mask were made at 3-m intervals seaward from shore during daylight hours. A total of 69 taxa (67 species) representing 33 families of fishes were observed. Total (53) and average fish species richness (32.7) at rocky beach habitats were greater than those (total=43; average=24.3) at sandy beach habitats. Twelve functional feeding groups were identified (diurnal planktivores, excavators/eroders, macroalgae browsers, macrocarnivores, mobile benthic scrapers, …
