The Effect Of Mast Availability On Ambush Site Selection In Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Berlynna May Heres
The Effect Of Mast Availability On Ambush Site Selection In Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Berlynna May Heres
Theses, Dissertations and Capstones
I examined ambush site selection in eastern diamondback rattlesnakes (Crotalus adamanteus). The eastern diamondback rattlesnake (EDB) is an imperiled, ambush predator endemic to southeastern pine savannas and woodlands of the United States. Eastern diamondbacks prey on small mammals that feed on hard and soft mast (e.g., nuts and fruits). In this study, I hypothesized that intra-seasonal shifts in masting vegetation would cause intra-season shifts in ambush site selection in EDBs as the result of a bottom-up trophic effect. I quantified EDB ambush site selection using radio telemetry data and vegetation analysis within a naturalized study site. When EDBs were encountered …

Ecological niche theory suggests two species cannot live in the same ecological niche and differences should exist among species that appear to cohabitate. Variations in physiology and behavior that potentially enable species coexistence can be reflected in metabolism. This study investigated coexisting darter fishes by measuring the metabolism of greenside (Etheostoma blennioides) and variegate (E. variatum) darters over 48 h using intermittent-flow respirometry. Activity was analyzed using time-lapse videos. E. blennioides mean metabolic rate (154.64 ± SE 52.54 mg O2·kg-1 ·hr-1 ; n=14; p=0.0006) was significantly greater than and varied more than E. variatum’s mean rate (92.51 ± SE 32.70 …
Hibernacula Site Selection Of The Eastern Box Turtle, Terrapene C. Carolina, In A West Virginia Population, Benjamin Owen Koester
Hibernacula Site Selection Of The Eastern Box Turtle, Terrapene C. Carolina, In A West Virginia Population, Benjamin Owen Koester

Eastern Box Turtles (Terrapene c. carolina) are a terrestrially hibernating reptile found throughout the eastern United States. Despite their prevalence, little, outside of anecdotal observations, is known about their hibernacula selection. This study examines if they preferentially select hibernacula locations, and if so, what characteristics they select in a West Virginia population. Over the course of two years, radio-tagged turtles (n=12) were followed into hibernation in Wayne County, WV. Upon entering hibernation, ~36 data point were collected in a grid-like fashion around the hibernacula, with an additional point collected at the hibernacula. At each point, seven variables were recorded: soil …

Analysis of West Virginia Department of Environmental Protection (WVDEP) agency’s Stream Condition Index and habitat assessment data compared two cycles of data. Geographic Information System (GIS) was used to develop a kriging model to project scores. Scores were calculated for Hydrologic Unit Code (HUC) eight and ten using Zonal statistics. The Getis-Ord Gi Star was used to identify high and low value clusters. Land use and impervious surface data was gathered from the United States Geological Survey (USGS) to assess impacts to watersheds. The results for WVSCI and habitat assessment showed that there was an improvement between cycles. Negative WVSCI …

Analyzing Pterosaur Ontogeny And Sexual Dimorphism With Multivariate Allometry, Erick Charles Anderson
Theses, Dissertations and Capstones
The relationships of pterosaurs have been previously inferred from observed traits, depositional environments, and phylogenetic associations. A great deal of research has begun to analyze pterosaur ontogeny, mass estimates, wing dynamics, and sexual dimorphism in the last two decades. The latter has received the least attention because of the large data set required for statistical analyses. Analyzing pterosaurs using osteological measurements will reveal different aspects of size and shape variation in Pterosauria (in place of character states) and sexual dimorphism when present. Some of these variations, not easily recognized visually, will be observed using multivariate allometry methods including Principle Component …

Monitoring programs often suffer from imperfect detection resulting in skewed population estimates, biased estimates of changes in occupancy over time, and can result in an underestimated proportion of area occupied (PAO) by a species. To increase the detection probability, researchers must increase sampling both spatially and temporally. Callback surveys are an active form of sampling that have been used to monitor many avian and mammal species. During callback surveys, the call of a conspecific male is projected with the intention of increasing probability of detection by eliciting a response from territorial males. These methods work for organisms that establish breeding …

Interactions between free-ranging primates and their associated parasitic forms continue to be a point of interest in ecology for several reasons. External and internal parasitism is not atypical for wild populations of primates, and the repercussions of these relationships can range from benign to life-threatening and capable of altering the structure of naturally occurring groups. The ecological relationship between the golden mantled howler monkey (Alouatta palliata palliata) and its host-specific ectoparasite, the howler monkey bot fly (Alouattamyia baeri) poses significant potential detriment to the overall body quality and success of the host primate. A. p. palliata has also been recorded …
