Modeling Chlorophyll Concentrations On The Ohio River Using Remotely Sensed Data, Thaddaeus Stephen Tuggle
Modeling Chlorophyll Concentrations On The Ohio River Using Remotely Sensed Data, Thaddaeus Stephen Tuggle
Theses, Dissertations and Capstones
Traditional direct water quality methodologies limit the ability to spatially and temporally predict algal blooms in lotic systems due to the size and characteristics of large river systems. Algal blooms potentially can be predicted by knowing the spatial and temporal patterns of change in cyanobacteria concentrations at large scales. Remote sensing studies investigating freshwater algal blooms, some known to secrete harmful toxins, are primarily conducted on lentic systems while large lotic systems are greatly ignored. In this study I developed a chlorophyll concentration estimation model for the Ohio River using a satellite remote sensing approach. Ground-truth water quality measures, including …
Population Level Responses To Direct Application Liming In Gyrinophilus Porphyriticus, Shelby Renea Timm
Population Level Responses To Direct Application Liming In Gyrinophilus Porphyriticus, Shelby Renea Timm
Theses, Dissertations and Capstones
Direct application liming (DAL) has been used to neutralize acidified streams to restore aquatic biota. This mitigation technique has been used globally for decades, yet little data exist on its effects on amphibian populations. My study investigated the effects of liming on amphibians by measuring variability in life histories of larval Gyrinophilus porphyriticus. I collected larvae from six streams in the Monongahela National Forest, West Virginia. I examined the effects of DAL on age structure, and I failed to detect a treatment effect. I used ANCOVAs to examine differences in body condition, body size, and gape size. I observed that …
Dietary Preference Of The Queensnake (Regina Septemvittata), Timothy J. Brust
Dietary Preference Of The Queensnake (Regina Septemvittata), Timothy J. Brust
Theses, Dissertations and Capstones
The Queensnake (Regina septemvittata) is a small secretive water snake found throughout the eastern United States. Once common, their numbers have declined to the extent that they are now threatened throughout most of their range, largely the result of pollutant-based reduction in prey species. These snakes are assumed to eat molted crayfish exclusively. For some common crayfish species, molting happens only twice a summer during a two- week period. It has not been documented if Queensnakes eat anything besides crayfish on a regular basis. The purpose of this study was to determine the prey preference of Queensnakes with particular focus …
The Natural History And Thermal Ecology Of A Population Of Spotted Turtles (Clemmys Guttata) And Wood Turtles (Glyptemys Insculpta) In West Virginia, Ariana N. Breisch

Theses, Dissertations and Capstones
An ecological study was conducted from 19 March 2001 to 2 April 2003 on a population of Spotted Turtles (Clemmys guttata) and Wood Turtles (Glyptemys insculpta) in West Virginia. Live-trapping, mark-recapture, radio telemetry and temperature data logging techniques were used to gather information on morphometrics, capture success, movements, home range, behavior, and thermal regime during activity and over-wintering seasons. Twenty-one Spotted Turtles were captured 260 times. Population structure was 42.9% juvenile, 38.1% male, and 19.0% female. Mean home range was 0.52 ha. Fifty Wood Turtles were captured 230 times. Juveniles were 36%, and males and females were 32% each. Mean …
Spatial Heterogeneity Of Soil Nutrients, Nitrogen Dynamics, And Vegetation In A 3rd Order Stream Floodplain In Southwestern West Virginia, David Allen Dick
Spatial Heterogeneity Of Soil Nutrients, Nitrogen Dynamics, And Vegetation In A 3rd Order Stream Floodplain In Southwestern West Virginia, David Allen Dick
Theses, Dissertations and Capstones
Soil processes often exhibit spatial heterogeneity within ecosystems and this heterogeneity may influence community structure. This study was conducted to determine spatial patterns and variability of soil nutrients and plant communities within different vegetation types in a stream floodplain in southwestern West Virginia. One 5-m × 5-m site was established in each of three vegetation/drainage types: pasture (PA), old field (OF), and wetland scar (SC). Pasture and SC sites were located ~25 m apart on flat bottomland; the OF site was located on a moderate slope 6.3 m above bottomland, ~200 m from PA and SC. A 10-m × 1-m …

Life History, Ecology, And Low Ph Tolerance Of The Freshwater Prawn, Palaemonetes Kadiakensis Rathbun, In A Mitigated Wetland Of The Green Bottom Wildlife Management Area, West Virginia, Jennifer Ann Aderman
Theses, Dissertations and Capstones
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 …
An Ecological Study Of Shale Barren Rock Cress (Arabis Serotina Steele) At Little Fork Shale Barren, Pendleton County, West Virginia, Robert J. Jarrett
An Ecological Study Of Shale Barren Rock Cress (Arabis Serotina Steele) At Little Fork Shale Barren, Pendleton County, West Virginia, Robert J. Jarrett
Theses, Dissertations and Capstones
Shale Barren Rock Cress (Arabis serotina Steele) was listed as a federally endangered species by the U.S. Fish and Wildlife Service in August 1989. As part of a cooperative agreement between the West Virginia Natural Heritage Program and the U.S. Navy, research was conducted in 1994 and 1995 at Little Fork Shale Barren (LFSB) to provide baseline information on the population dynamics of A. serotina and to study the vegetation and physical parameters associated with this shale barren community. Soil samples and plant community data were collected from 40 1-m2 circular plots for herbaceous vegetation and six 0.02-ha …
Diet And Growth Of Larval And Juvenile Grass Pickerel, Esox Americanus Vermiculatus, And Central Mudminnow, Umbra Limi, In The Green Bottom Wildlife Management Area, Cabell County, West Virginia, Erica Midkiff
Theses, Dissertations and Capstones
The grass pickerel, Esox americanus vermiculatus, is listed as Undetermined on the Vertebrate Species List of Concern in West Virginia. The central mudminnow, Umbra limi, is a disjunct population in Green Bottom Swamp. The lentic, vegetated areas that are required for spawning for the grass pickerel and the central mudminnow have been reduced by residential, agricultural, and industrial developments. Green Bottom Swamp, a naturally occurring wetland of 58 ha, and a nearby mitigated wetland of 29 ha, provides spawning habitat for the grass pickerel and the mudminnow. Fishes were collected in beds of Potamogetan crispus and Ceratophyllum demursum …

Theses, Dissertations and Capstones
An ecological study of the wood turtle, Clemmys insculpta (LeConte), was conducted in West Virginia from May 1991 to March 1993. Population structure at the primary study area (WV #1) was estimated to be 46% juvenile (H-8 yrs. old), 26% female and 28% male. Total population estimate for WV #1 was 337 wood turtles, with an aquatic density of 1,980 turtles per Hectare of river and a terrestrial density of 22.5 turtles per ha of terrestrial habitat. Growth measurements and estimates indicate rapid initial growth tapering off at year 8 and gradually declining through year 16. Males grow slightly faster …
Comparative Ecological, Morphological, And Behavioral Studies Of The Southern Blacknose Dace, Rhinichthys Atratulus Obtustjs Agassiz, And The Eastern Blacknose Dace, Bhinichtbis Atbatulus Atra'fulus (Hermann), In High And Low Altitude Streams In West Virginia And Virginia, Michael L. Little
Theses, Dissertations and Capstones
Comparative ecological, aorphological, and behavioral studies of the southern blaeknose dace, Rhiniohthys atratulus obtusus Agassiz, and the eastern blaokaose dace, B.hiniohtpys atratulus atratulus (Heraann), were made in high and low altitude streaas in West Virginia and Virginia. Statistical comparisons of the morphology of a. a.atratulus and R-.a.-obtusus showed no reliable body character that differentiated the two subspecies. Statistical tests indicated an intergrading population in Gandy Creek, a tributary of the Cheat River, in West Virginia. This was further substantiated by collecting males of the atratulus phenotype along with males of the native obtusus phenotype in adjacent sections of Gandy Creek. …
