Factors Associated With Acoustic Bat Presence During Spring Emergence In The Appalachian Mountains Of Western Virginia, Emily Kirk Pody
Factors Associated With Acoustic Bat Presence During Spring Emergence In The Appalachian Mountains Of Western Virginia, Emily Kirk Pody
Theses, Dissertations and Capstones
Studies of threats that bats face during hibernation have increased in response to white-nose syndrome (WNS), a fungal disease that has ravaged North American bat populations. However, impacts of WNS on bat ecology during spring emergence, when bats are potentially recovering from infection and allocating resources for reproduction, is relatively understudied. As more bat species become listed at the federal and state level, the need to understand the factors associated with spring emergence is critical for improving conservation guidelines and habitat management practices. Acoustic monitoring is an efficient method for monitoring bat presence for prolonged periods of time, giving biologists …
A Characterization Of West Virginia Coyotes (Canis Latrans) Utilizing Skull Morphology, Katharina E. Scholer
A Characterization Of West Virginia Coyotes (Canis Latrans) Utilizing Skull Morphology, Katharina E. Scholer
Theses, Dissertations and Capstones
Coyotes (Canis latrans) are now found throughout North and Central America, but before European colonization were restricted to west of the Mississippi. Migration occurred in two major paths to the East; north over the Great Lakes (through Canada) and south below the Great Lakes. The location of these routes is significant because those migrating north interbred with the wolves that reside there. These hybrid animals are larger and behaviorally different from their western counterparts. It is possible to differentiate these hybrids morphologically and genetically. Hybrids are known to be located in Maine, New York, and Pennsylvania, but the interest of …
Factors Influencing Spatial Variability In Soil Nitrogen (N) Dynamics In N-Treated And Untreated Watersheds Of The Fernow Experimental Forest, West Virginia, Nikki Lenore Lyttle
Factors Influencing Spatial Variability In Soil Nitrogen (N) Dynamics In N-Treated And Untreated Watersheds Of The Fernow Experimental Forest, West Virginia, Nikki Lenore Lyttle
Theses, Dissertations and Capstones
The central Appalachian region of the United States receives some of the highest inputs of nitrogen (N) due to acidic deposition in the nation. It is believed that these high could levels contribute to a decline in forest soils within the next 50 to 70 yrs. This study examines factors that influence spatial variability in N-treated and untreated watersheds of the Fernow Experimental Forest, Parsons, West Virginia. Within each of the two watersheds [WS4 untreated control, > 100 yr.; WS3 N-treated, acidified, clear cut, ~ 31 yr.], two 0.04 ha plots, one high N and one low N, were selected for …
The Life History Of The Cave Salamander, Eurycea Lucifuga Rafinesque, In West Virginia, Andrew James Longenecker
The Life History Of The Cave Salamander, Eurycea Lucifuga Rafinesque, In West Virginia, Andrew James Longenecker
Theses, Dissertations and Capstones
In West Virginia, as throughout its range, there is limited information about the life history of the cave salamander (Eurycea lucifuga). The purpose of this study was to describe the natural history of this species in West Virginia. The objectives of this study were to determine habitat selection of the cave salamander, to ascertain its environmental characteristics, and to study its reproductive and non-reproductive biology. Three study caves were located in Greenbrier County, West Virginia. All sites were examined at least once each month from May 1999 through April 2000. Caves were divided into three zones: entrance, twilight, …
Ecology And Sympatric Relations Of Crevice Salamanders In Randolph County, West Virginia, Jayme Linn Waldron
Ecology And Sympatric Relations Of Crevice Salamanders In Randolph County, West Virginia, Jayme Linn Waldron
Theses, Dissertations and Capstones
By implementing a mark-recapture study, I investigated the ecology of three species of sympatric plethodontid salamanders (Aneides aeneus, Desmognathus ochrophaeus, and Plethodon glutinosus) on rock outcrops in the Westvaco Wildlife and Ecosystem Research Forest, Randolph County, West Virginia. By examining activity patterns, vertical stratification, and habitat preference for A. aeneus, D. ochrophaeus, and P. glutinosus, I attempted to offer some insight into how these sympatric species avoid competition on small, isolated rock outcrops. Twenty-one surveys, both nocturnal and diurnal, were performed between 11 May and 17 October, 1999. During this time, 89 salamanders, encompassing five species ( …
Changes Among Ohio River Fish Populations Due To Water Quality Improvements And High-Lift Dams, Benjamin Lowman
Changes Among Ohio River Fish Populations Due To Water Quality Improvements And High-Lift Dams, Benjamin Lowman
Theses, Dissertations and Capstones
Fish populations in the Ohio River have been monitored extensively by the Ohio River Valley Water Sanitation Commission (ORSANCO), along with state and Federal agencies, for over 40 years. The population data, collected via lock chamber rotenone surveys, showed that many species of Ohio River fish have demonstrated marked increases in abundance since these studies began. These trends in population density, both gradual and sharp, are likely associated with water quality improvements and the construction of high-lift dams. Pearson-r correlation through linear regression analyses showed 23 species or 42% of populations examined exhibit significant density increases from 1957 to 1998. …
Distribution Of The Sucker Family (Pisces: Catostomidae) In The Ohio River, Tara L. Rose
Distribution Of The Sucker Family (Pisces: Catostomidae) In The Ohio River, Tara L. Rose
Theses, Dissertations and Capstones
The family Catostomidae represents a major component of the fish fauna in the Ohio River. Because of their abundance, large biomass, and susceptibility to environmentally-induced anomalies, suckers are expected to significantly influence the Ohio River Fish Index (ORFIn), a biological index being developed by the Ohio River Valley Water Sanitation Commission (ORSANCO) for large river systems. To correctly interpret information obtained from ORFIn, the impact of suckers upon the index must be thoroughly understood, including relative importance and uneven spatial distribution of Ohio River suckers. In this study, suckers represented 7.1 percent of the total fish captured and 36.6 percent …

Ecology And Natural History Of Rana Clamitans Melanota In West Virginia, Alison M. Rogers
Theses, Dissertations and Capstones
Fourteen study sites were sampled with aquatic funnel traps and D-frame net sweeps in the plateau and mountain region of West Virginia to determine differences in larval period. Larval stage class abundance and larval total length and mass measurements were recorded from February to December 1997. Larval stage classes 25 and 26, the first free living stages, were absent from the plateau region from February to April, but were present in the mountain region. Pre-transformation larval stages, 40 through 44, were found from May through October, and peaked in July. Significant relationships were found with simple linear regression analysis between …
Ecology And Natural History Of The Cow Knob Salamander, Plethodon Punctatus Highton, In West Virginia, Robert B. Tucker
Ecology And Natural History Of The Cow Knob Salamander, Plethodon Punctatus Highton, In West Virginia, Robert B. Tucker
Theses, Dissertations and Capstones
Very little has been written on the ecology and natural history of the Cow Knob salamander, Plethodon punctatus Highton, since it was described by Highton (1971). Plethodon punctatus is known only from the higher elevations of Great North (above 2,800 ft) and Shenandoah (above 3,000 ft.) Mountains in Virginia and West Virginia (Highton, 1972; Conant and Collins, 1991). The type locality is Cow Knob, Pendleton County, West Virginia. Plethodon punctatus is a large (up to 75 mm snout-to-vent length) dorso-ventrally flattened salamander with creamish iridiophore spots on the back and sides, webbed feet for a fossorial lifestyle, and large …

An ecological life history study of the freshwater prawn Palaemonetes kadiakensis was conducted at the mitigated wetland of the Green Bottom Wildlife management Area (GBWMA). Monthly samples were collected from November 1996 through November 1997. In addition, weekly samples were collected from May through November for growth and reproductive analysis. Monthly samples yielded 520 prawns. Palaemonetes kadiakensis had a one-year life cycle, with all adults dying by September. Males averaged 23.82 mm (range = 14.15 to 36.75 mm) and females averaged 26.78mm (range = 15.06 to 38.60 mm) in length. Males averaged 0.087g (range = 0.014to 0.293 g) and females …
The Use Of Emergent Rocks As Refugia For The Cheat Mountain Salamander, Plethodon Nettingi Green, Beth Anne Pauley
The Use Of Emergent Rocks As Refugia For The Cheat Mountain Salamander, Plethodon Nettingi Green, Beth Anne Pauley
Theses, Dissertations and Capstones
Plethodon nettinqi was listed as a threatened species in 1989 by the United States Fish and Wildlife Service (Pauley, 1991). Its total range is within 5 counties in eastern West Virginia. There are fewer then 60 disjunct populations known and most populations are above 3,000 ft. and are associated with emergent rocks or narrow ravines with Rhododendron. It is hypothesized the P. netting! survived lumbering practices at the turn of the century by taking refuge beneath large emergent rocks and narrow ravines with Rhododendron. This study examined environmental factors associated with emergent rocks that might regulate the distribution of P. …
Observations On Reproduction, Isozyme Patterns, And Meristics In Mosquitofish (Pisces: Poeciliidae) From West Virginia, Matt Mcreynolds
Observations On Reproduction, Isozyme Patterns, And Meristics In Mosquitofish (Pisces: Poeciliidae) From West Virginia, Matt Mcreynolds
Theses, Dissertations and Capstones
Prior to 1988, two subspecies of the mosquitofish Gambusia affinis (G. a. affinis and G. a. holbrooki) were recognized along the Gulf and Atlantic Coasts of the United States. Based on electrophoretic analysis, subsequent investigators recognized G. holbrooki and G. affinis as separate species. Populations in drainages west of Mobile Bay were considered G. affinis, and those east of this divide being G. holbrooki. The only mosquitofish population in West Virginia is found in the Meadow River wetlands (1392 ha). This wetland complex is located at the western end of Greenbrier County in the Allegheny Mountain Province. …
