Effects Of Developmental Activities On Streamside Salamander Communities In Boone County, West Virginia, Mindy S. Hamilton

Theses, Dissertations and Capstones

A study was conducted from May 1998 through June 1999 in three streams associated with mountaintop mining and valley fills in Boone County, West Virginia. Streamside salamander communities were monitored in these streams, as well as in two relatively undisturbed reference streams in the region, using refugia bags, rock-on-rock methodology, and day surveys. The relative abundance of salamanders was compared between the streams in order to detect effects of the associated valley fills to downstream biota. Relative abundance was lower in two of three streams associated with valley fills as compared to the reference streams. However, there was no significant …

Determining The Genetic Distances Between Sub-Populations Of Aneides Aeneus In The Westvāco Wildlife And Ecological Research Forest, Andrew Nicholas Johnson

Theses, Dissertations and Capstones

Aneides aeneus, the Green Salamander, is a plethodontid species ranging from southern Pennsylvania to central Alabama and from eastern Mississippi to Maryland. Populations of Green Salamanders most often inhabit cliffs and rocky outcrops which are moist but not wet and shaded. The animal is listed as a species of special concern by the West Virginia Division of Natural Resources Wildlife Diversity Program. Genetic and reproductive isolation due to strict habitat preferences of the Green Salamander could be a factor in the decline of the species. Seventeen tissue samples were retrieved from five sites within the Westvāco Wildlife and Ecosystem …

Fisheries Research Report No. 137 - Annual Report On The Monitoring Of The Recreational Marron Fishery In 2000, With An Analysis Of Long-Term Data And Changes Within This Fishery, Brett Molony, Chris Bird

Fisheries Research Reports

This report presents the data from the 2000 season and compares the results with previous records. Although the 2000 marron season was relatively successful compared to the 1999 season it was still modest in terms of the historical records. Further, the recreational marron fishery continues to be declining in terms of catch rate, CPUE and other indicators derived from four data sources. The discussion highlights the variable nature of marron populations and the possible causes of the very different population structures of marron within the fishery. Further, possible reasons for the long-term decline of the marron fishery are discussed. It …

Status Of The Small-Mouthed Salamander, Ambystoma Texanum (Mathes) In West Virginia, Robert Fiorentino

Theses, Dissertations and Capstones

Over the past 60 years little natural history information on Ambystoma texanum (Small-mouthed Salamander) has been collected in West Virginia, the eastern most location for the species. Three historical breeding populations of A. texanum have been documented in the state, but salamanders from 2 of these locations have not been documented for the past 30 years. Searches of historical sites and favorable habitat in Mason, Jackson, and Wood counties yielded no evidence for the presence of A. texanum, except for the known breeding site in Wood County. Information on time of breeding and egg development was collected at the Wood …

Effects Of Fish Cage Aquaculture On The Zooplankton In A Malaysian Mangrove Estuary, Ai Lin Ooi

Student Works (2000-2009)

A study on the effects of fish cage aquaculture on the zooplankton was carried out in the Matang mangrove estuary, Perak, Malaysia. Investigations consisting of 4-month study and 12-hour study were conducted. Zooplankton were sampled inside and away from floating fish cage culture areas in Sangga Besar (SSB) river and in an adjacent nonaquaculture river, Sangga Kecil (SSK), in order to examine the effect of fish cage culture on zooplankton abundance. Zooplankton populations varied both spatially (being more abundant towards the river mouth) and temporally (being more abundant at certain months, e.g. in December). In SSB, fish cage culture had …

Colony Composition And Demographics Of Beavers In Illinois, Stanley T. Mctaggart

Masters Theses

Beavers (Castor canadensis) have been extensively studied throughout North America, but little research has been conducted on this species in Illinois and the Midwest. Beavers exhibit wide variations in colony composition and demographics over their broad geographic range, so regional research is important for sound management. The objectives of this study were to investigate the: (1) typical composition of beaver colonies in Illinois; (2) reproductive potential of female beavers in Illinois; (3) sex-age composition of beaver populations in Illinois; and (4) efficacy of night-vision surveys versus removal trapping for estimating colony size. This study was conducted during the 1999-00 and …

Morphological Variation Of Allocreadium Lobatum (Digenea: Allocreadiidae) In The Creek Chub, Semotilus Atromaculatus (Osteichthyes: Cyprinidae), In Nebraska, Usa, Monte S. Willis

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Allocreadium lobatum Wallin 1909, a parasite of fresh-water fish, was originally described as having distinct lobate testes, and subsequent descriptions have left this original description unchanged. The present study quantifies the observation of distinctly non-lobate testes that could be categorized as round or asymmetrical in addition to the previously described lobate testes. Six hundred thirty-six A. lobatum were collected from 228 Semotilus atromaculatus over a 9 month period. Overall, 21.3%, 61.6%, and 16% were found to be round, asymmetrical, and lobate testes respectively (N = 1,071). Analysis of testis morphology found the increasing presence of lobate testis as …

Discounting And Reciprocity In An Iterated Prisoner’S Dilemma, David W. Stephens, Colleen M. Mclinn, Jeffrey R. Stevens

Jeffrey Stevens Publications

The Iterated Prisoner’s Dilemma (IPD) is a central paradigm in the study of animal cooperation. According to the IPD framework, repeated play (repetition) and reciprocity combine to maintain a cooperative equilibrium. However, experimental studies with animals suggest that cooperative behavior in IPDs is unstable, and some have suggested that strong preferences for immediate benefits (that is, temporal discounting) might explain the fragility of cooperative equilibria. We studied the effects of discounting and strategic reciprocity on cooperation in captive blue jays. Our results demonstrate an interaction between discounting and reciprocity. Blue jays show high stable levels of cooperation in treatments with …

Development Of The Muskox Lungworm, Umingmakstrongylus Pallikuukensis (Protostrongylidae), In Gastropods In The Arctic, Susan J. Kutz, Eric P. Hoberg, John Nishi, Lydden Polley

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Development of the muskox protostrongylid lungworm, Umingmakstrongylus pallikuukensis, in its slug intermediate host, Deroceras laeve, was investigated under field conditions in the Arctic. Every two weeks, from 19 June to 28 August 1997, groups of ten experimentally infected slugs were placed in tundra enclosures in a mesic sedge meadow near Kugluktuk, Nunavut, Canada. First-stage larvae (L1) infecting slugs on or before 17 July developed to third-stage larvae (L3) in 4–6 weeks. Intensity of L3 in slugs peaked at 6–8 weeks post infection (PI) and then progressively declined by 10, 12, and 48–50 weeks PI. Abundance of L3 in …

Modeling Bighorn Sheep Habitat In Northwest Nebraska, Kyle M. Forbes

Department of Geography: Dissertations, Theses, and Student Research

In recent years geographic information system (GIS) and remote sensing technologies have been used extensively in habitat suitability modeling. By incorporating these technologies, scientists often gain the ability to formulate and implement a more detailed habitat suitability model with the addition of more detailed spatial information. A habitat suitability model was developed to quantify and describe the available suitable Rocky Mountain bighorn sheep (Ovis canadensis canadensis) habitat in the Pine Ridge of northwestern Nebraska and determine if a minimum viable population (MVP) of this species can be supported naturally in the region. The model included a strong spatial …

A Cytochrome-B Perspective On Passerina Bunting Relationships, John Klicka, Adam J. Fry, Robert M. Zink, Christopher W. Thompson

Ornithology Program (HRC)

We sequenced the complete mitochondrial cytochrome-b gene (1,143 nucleotides) for representatives of each species in the cardinalid genera Passerina (6 species), Guiraca (1 species), and Cyanocompsa (3 species), and used a variety of phylogenetic methods to address relationships within and among genera. We determined that Passerina, as presently recognized, is paraphyletic. Lazuli Bunting (P. amoena) is sister to the much larger Blue Grosbeak (Guiraca caerulea). Indigo Bunting (P. cyanea) and Lazuli Bunting are not sister taxa as generally thought. In all weighted parsimony trees and for the gamma-corrected HKY tree, Indigo Bunting is …

Effectiveness Of Earthen Escape Ramps In Reducing Big Game Mortality In Utah, Mary L. Hammer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One-way escape gates and earthen escape ramps are structures used to enable deer to exit the highway right-of-way along fenced roads. I compared the use of one-way escape gates and earthen escape ramps by mule deer on two highways in Utah to determine if deer exhibited a preference for either structure. Results showed that earthen escape ramps were used by mule deer 8-11 times more frequently than one-way gates. Highway mortality data suggest that the installation of the escape ramps likely reduced mortality of mule deer in both study locations, because we could not attribute reductions in mortality to decreased …

The Taxonomic Rank Of Spizella Taverneri: A Response To Mayr And Johnson, John Klicka, Robert M. Zink, Jon C. Barlow, W. Bruce Mcgillivray, Terry J. Doyle

Ornithology Program (HRC)

Mayr and Johnson suggest that Spizella taverneri should be a subspecies of the biological species S. breweri, because it is possibly not reproductively isolated. We originally concluded that evidence from mitochondrial DNA sequences, habitat preferences, timing of breeding, vocalizations, and morphology supported the recognition of S. taverneri as a phylogenetic and biological species. Nothing in the commentary by Mayr and Johnson causes us to change that conclusion. We believe that it is probable that these two allopatric taxa are isolated. Contrary to Mayr and Johnson, we believe that more information is given by ranking S. taverneri as a species, because …

Natural History And Roosting Ecology Of The Eastern Pipistrelle, Pipistrellus Subflavus, Jacques Pierre Veilleux

All-Inclusive List of Electronic Theses and Dissertations

A study concerning the natural history and roosting ecology of the eastern pipistrelle, Pipistrellus subtlavus, was conducted from 1997 to 2000, in southern Vigo County, Indiana. 111 Females began forming pre-maternity colonies during early May, and parturition began during late June. Pre-maternity colonies averaged 3.7 ± 1.9 individuals, and maternity colonies averaged 4.4 ± 2.4 individuals. Young pipistrelles first became volant during the third and fourth weeks of July. Pipistrelles were located in 59 roost trees. All roosts were located in foliage, either in clusters of dead leaves (n = 40) or in live foliage (n = 19). Oaks (Ouercus …

Intensification In A Risky Environment: The Case Of Improving Private Grazing Land For Beef Production In Utah, Louise D. Sainsbury

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah ranchers commonly face risks to their livelihoods. The objective of this work was to determine if ranchers could make profitable improvements to private land forage given the combined threat of low beef prices, drought, and possible loss of public grazing.

We used linear programming (LINDO) to identify the most profitable solutions for private land investment with an 11-year simulation. Operations were divided into small, medium, and large size classes. Various forage improvements and public permits were options. Two phases of a beef price cycle (peak and trough) and 2 precipitation patterns (wet and drought) were combined as joint favorable …
