Pcr Prevalence Of Ranavirus In Free-Ranging Eastern Box Turtles (Terrapene Carolina Carolina) At Rehabilitation Centers In Three Southeastern Us States, Matthew Allender, M Abd-Eldaim, Juergen Schumacher, D Mcruer, L Christian, Melissa Kennedy Jan 2012

Pcr Prevalence Of Ranavirus In Free-Ranging Eastern Box Turtles (Terrapene Carolina Carolina) At Rehabilitation Centers In Three Southeastern Us States, Matthew Allender, M Abd-Eldaim, Juergen Schumacher, D Mcruer, L Christian, Melissa Kennedy

Juergen P. Schumacher

Ranaviruses (genus Ranavirus) have been observed in disease epidemics and mass mortality events in free-ranging amphibian, turtle, and tortoise populations worldwide. Infection is highly fatal in turtles, and the potential impact on endangered populations could be devastating. Our objectives were to determine the prevalence of ranavirus DNA in blood and oral swabs, report associated clinical signs of infection, and determine spatial distribution of infected turtles. Blood and oral swabs were taken from 140 eastern box turtles (Terrapene carolina carolina) that were presented to the wildlife centers at the University of Tennessee (UT; n=39), Wildlife Center of Virginia (WCV; n ...


An Assessment Of Moose (Alces Alces Americana) And Moose Management In Connecticut, Andrew M. Labonte Dec 2011

An Assessment Of Moose (Alces Alces Americana) And Moose Management In Connecticut, Andrew M. Labonte

Master's Theses

Eastern moose (Alces alces americana) populations have been increasing in New England over the past decade. Moose populations have the potential to generate human conflict due to their size, speed, nocturnal behavior, and seasonal mobility. As problems associated with increasing moose populations become more common, the need to develop management strategies that are both effective and acceptable to stakeholders becomes increasingly important. The potential for moose to continue to expand in southern New England and the long-term impacts they may have on Connecticut residents, is unclear. The overall purpose of this study was to assess how suitable Connecticut is for ...

Stable Isotope Analyses Of Bat Fur: Applications For Investigating North American Bat Migration, Erin E. Fraser Dec 2011

Stable Isotope Analyses Of Bat Fur: Applications For Investigating North American Bat Migration, Erin E. Fraser

Electronic Thesis and Dissertation Repository

Many aspects of North American bat migration are not well documented. Stable isotope analyses of animal tissues can elucidate migratory origin, but this technique has not been widely applied to bats. This dissertation i) uses fur stable isotope analyses to investigate North American bat migration and ii) highlights some of the strengths and weaknesses of this analytical technique when applied to bat systems. I conducted stable hydrogen, carbon, and nitrogen isotope analyses on fur from five bat species.

I documented δDfur heterogeneity in summer resident populations of Myotis lucifugus, Lasiurus borealis, Lasiurus cinereus, and Lasionycteris noctivagans. Stable hydrogen isotope ...

A Comparison Of The Effectiveness Of Scent Lures On Attracting Mesopredators, Tom Batter Dec 2011

A Comparison Of The Effectiveness Of Scent Lures On Attracting Mesopredators, Tom Batter

Environmental Studies Undergraduate Student Theses

A mesopredator is a medium-sized middle trophic level predator such as a raccoon (Procyon lotor), red fox (Vulpes vulpes), striped skunk (Mephitis mephitis), or coyote (Canis latrans; Crooks and Soule 1999). Mesopredators have long been trapped for recreational, economic, or academic reasons. Throughout human history trapping has been used to capture animals for food and skins, as well as to prevent personal harm and property damage from predators. In order to increase the probability of success, scent lures are often used as an attractant (Geary 1984, Mills et al. 2010, Schlexer 2008).


Avian Species Abundance In Response To Recreational Trail Use, Carrie A. Wencel Dec 2011

Avian Species Abundance In Response To Recreational Trail Use, Carrie A. Wencel

Environmental Studies Undergraduate Student Theses

Studies have indicated that non-consumptive outdoor recreation may affect wildlife. Thus, as the nation increases interest in outdoor recreation, data suggests the effect on wildlife will also increase. Previous studies indicate that as disturbance to wildlife increases, both avian species richness will decrease. Knowing how to anticipate effects on native species when planning and managing recreational areas is important in order to both provide for human desires and ensure the least impact to local species diversity.

The goal of this project was to observe and compare avian species richness and diversity between selected trail sites within Shevlin Park, Bend, Oregon ...


Prey Selection By The Northern Watersnake, Nerodia Sipedon, Kyle O' Connell Dec 2011

Prey Selection By The Northern Watersnake, Nerodia Sipedon, Kyle O' Connell

Environmental Studies Undergraduate Student Theses

Prey selection and composition of the northern waternake, Nerodia sipedon was investigated between 8/2010 and 3/2011 by palpation of stomach contents in the field and conducting laboratory trials. 41 snakes were captured, five yielded prey contents. Fish parts, freshwater mussels, and an insect exoskeleton were found. No amphibians were found despite availability at study sites. Snakes in the laboratory underwent 22 trials, feeding on 11 occasions. Snakes fed on an equal number of both fish species, revealing no selection. Further research is needed to determine the rate of digestion of N. sipedon.

Fall Field Report, August–November 2011, W. Ross Silcock Dec 2011

Fall Field Report, August–November 2011, W. Ross Silcock

Nebraska Bird Review

Overall, this fall migration was routine (waterfowl, warblers, sparrows), but there were a few unexpected highlights. The flooded Missouri River Valley provided habitat that led to some amazing fall counts: 3000 pelicans, 5700 coots, 338 American Golden-Plovers, and 1200 Pectoral Sandpipers. The 10,000 cormorants at Harlan County Reservoir may not have been affected by the Missouri River flooding, and were a record count also. While we're talking numbers, the martin roost in Omaha topped out at 50,000–55,000, and seasonal totals of 4 Red-necked Grebes and 15 Philadelphia Vireos for the state, 34 Mississippi Kites over ...

First Discovery Of A Four-Egg Clutch For Mountain Plover (Charadrius Montanus) In Nebraska, Bartholomew L. Bly, Travis Wooten Dec 2011

First Discovery Of A Four-Egg Clutch For Mountain Plover (Charadrius Montanus) In Nebraska, Bartholomew L. Bly, Travis Wooten

Nebraska Bird Review

On 27 May 2010, the first documented Mountain Plover nest in Nebraska to contain a clutch of four eggs was documented in a fallow strip of a dryland crop field in southern Kimball County. Mountain Plover typically have a clutch size of 3 eggs, though clutches with 1 and 2 eggs are observed in approximately 15% of nesting attempts (Knopf and Wunder 2006). Clutches with 4 eggs are rare and have been reported to occur in less than 1% of the population (Knopf and Wunder 2006). Five 4-egg clutches have been reported in Colorado and one in Montana (see Knopf ...


First Documented Nebraska Sighting Of Brown-Headed Nuthatch (Sitta Pusilla), Larry Einemann Dec 2011

First Documented Nebraska Sighting Of Brown-Headed Nuthatch (Sitta Pusilla), Larry Einemann

Nebraska Bird Review

Monday, November 8, 2010, was an unusually warm (upper 70s) autumn day for Lincoln, Nebraska, with no clouds and a wind from the southwest. I went to Holmes Lake Park in southeast Lincoln to scan for late migrating waterfowl and then to check the stand of conifers for the arrival of winter migrants. Around 11 A.M. I was attracted to a feeding group of six Black-capped Chickadees and three Red-breasted Nuthatches in the 30- to 40-year-old pines and Douglas firs north of Hyde Observatory. I noticed a differently patterned nuthatch in the group. I had seen a Pygmy Nuthatch ...

Movement Ecology Of An Intercontinental Migratory Bird During Spring Stopover, Emily Beth Cohen Dec 2011

Movement Ecology Of An Intercontinental Migratory Bird During Spring Stopover, Emily Beth Cohen

Dissertations

Movement ecology is a component of nearly all aspects of animal behavior and an animal’s decision to move is likely influenced by a complex combination of exogenous and endogenous factors. Therefore, an examination of the causes and consequences of organismal movement provides a conceptual framework for understanding complex behavioral strategies. My dissertation research is focused on the movement ecology of an intercontinental migratory songbird during spring migration. I adopted experimental approaches to study the factors influencing how a songbird migrant, red-eyed vireos (Vireo olivaceus), makes decisions in unfamiliar landscapes from the initiation of spring stopover.

I simulated the arrival ...


Turtles: The Animal Answer Guide, Fredric J. Janzen Dec 2011

Turtles: The Animal Answer Guide, Fredric J. Janzen

Ecology, Evolution and Organismal Biology Publications

Turtles are among the most universally adored organisms. They exhibit an instantly recognizable morphology, yet lead lives that are cryptic to the casual observer, thus questions naturally surface regarding all sorts of aspects of their biology and history. In the absence of informed experience, mythic explanations have arisen and even become entrenched culturally, often doing no favor to the turtles or to turtle biologists who must combat such nonsense on behalf of the animals. Into this informational void appears this volume prepared by the expert authors, with the assistance of many knowledgeable colleagues.


An Evaluation Of Population Estimators And Forage Availability And Nutritional Quality For White-Tailed Deer In Tennessee, Jared Tyler Beaver Dec 2011

An Evaluation Of Population Estimators And Forage Availability And Nutritional Quality For White-Tailed Deer In Tennessee, Jared Tyler Beaver

Masters Theses

Given the white-tailed deer’s (Odocoileus virginianus; deer) popularity and potentially negative impact on forested systems; Arnold Air Force Base (AAFB) in Tullahoma, Tennessee, USA has made minimizing negative deer impacts on biodiversity a priority. To address these management issues, I initiated a study on AAFB to investigate deer survey techniques and the effects of deer density on forage availability across vegetative communities.

Current use of infrared-triggered cameras (camera) for estimating deer populations does not provide a measure of precision critical for density estimation. I conducted a camera survey for deer in Wildlife Management Area (WMA) Units 1 and 2 ...


Global And Specific Controls Of Protein Synthesis In Hibernators, Peipei Pan Dec 2011

Global And Specific Controls Of Protein Synthesis In Hibernators, Peipei Pan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mammalian hibernation is a highly dynamic physiological process that is composed of a series of torpor bouts, wherein hibernators oscillate between periods of torpor and interbout arousal. Although normally vital to homeostasis, many energetically consumptive processes such as translation or protein synthesis are virtually ceased during hibernation. Earlier studies indicated that protein synthesis had fallen to almost negligible levels. Cap-dependent initiation of translation is well regulated by eukaryotic translation initiation factor 4E (eIF4E) and its binding partner eIF4E-binding protein 1 (4E-BP1) when hibernators cycle in and out the torpor state. Herein, I investigated well-characterized regulatory mechanisms of global and specific ...


Capture-Recapture Of White-Tailed Deer Using Dna Sampling From Fecal Pellet-Groups, Matthew James Goode Dec 2011

Capture-Recapture Of White-Tailed Deer Using Dna Sampling From Fecal Pellet-Groups, Matthew James Goode

Masters Theses

Reliable density estimates of game and keystone species such as white-tailed deer (Odocoileus virginianus) are desirable to set proper management strategies and for evaluating those strategies over time. However, traditional methods for estimating white-tailed deer density have been inhibited by behavior, densely forested areas that can hamper observation (detection), and invalid techniques of estimating effective trapping area. We wanted to evaluate a noninvasive method of mark-recapture estimation using DNA extracted from fecal pellets as the individual marker and for gender determination, coupled with a spatial detection function to estimate density (Spatially Explicit Capture-Recapture, SECR). We collected pellet groups from 11 ...


A Checklist Of The Scorpions (Arachnida: Scorpiones) Of Panama, With Two New Records, Rolando Teruel, Michiel A.C. Cozijn Nov 2011

A Checklist Of The Scorpions (Arachnida: Scorpiones) Of Panama, With Two New Records, Rolando Teruel, Michiel A.C. Cozijn

Euscorpius

In the present note, we compile a checklist of all scorpion species recorded from Panama. A total of three families, five genera and 14 species are confirmed to occur in the country, and previous records of two other families, four genera, and nine species are discarded as misidentifications, mislabelings, or accidental introductions. Two Buthidae species are herein recorded for the first time from Panama: Tityus tayrona Lourenço, 1991 (so far known only from northern Colombia) and one apparently undescribed species of Ananteris Thorell, 1891.

On Centruroides Margaritatus (Gervais, 1841) And Closely Related Species (Scorpiones: Buthidae), Luis F. De Armas, Rolando Teruel, František Kovařík

Euscorpius

Centruroides edwardsii (Gervais, 1843) comb. nov. is restored as a valid species, and a male neotype from Riohacha, La Guajira Department, Colombia is herein designated; this species ranges from Mexico through Colombia, but there are no reliable records from Guatemala, Belize, and Panama; introduced populations also occur in Cuba (West Indies) and Senegal (Africa). We regard the following species as its junior synonyms: Scorpio (Atreus) degeerii Gervais, 1844, Centrurus gambiensis Karsch, 1879, Centruroides margaritatus septentrionalis Hoffmann, 1932, and Rhopalurus danieli Prado et Rios-Patiño, 1940. We also consider Centruroides margaritatus morenoi Mello-Leitão, 1945 as a junior synonym of Centruroides margaritatus (Gervais ...

Diagnosis Of Parelaphostrongylus Spp. Infection As A Cause Of Meningomyelitis In Calves, K Mitchell, J Peters-Kennedy, T Stokol, Richard Gerhold Jr., R Beckstead, T Divers Oct 2011

Diagnosis Of Parelaphostrongylus Spp. Infection As A Cause Of Meningomyelitis In Calves, K Mitchell, J Peters-Kennedy, T Stokol, Richard Gerhold Jr., R Beckstead, T Divers

Richard W. Gerhold Jr., DVM, MS, PhD

Migration of Parelaphostrongylus spp. has been documented to cause central nervous system damage in a number of aberrant host species but appears to be uncommon in cattle. The current report describes the clinical and laboratory findings, antemortem and definitive diagnosis, and response to treatment of Parelaphostrongylus spp. infection in five 3-7- month-old Limousin calves from 2 farms. All calves had signs of acute (n = 2) and chronic (n = 3) progressive spinal cord dysfunction. Cerebrospinal fluid analysis revealed a marked eosinophilic (acute cases) or lymphocytic (chronic cases) pleocytosis and elevated protein in all calves. A necropsy and histopathologic evaluation was performed ...


Autotomy Of The Posterior Foot In Agaronia Propatula (Caenogastropoda: Olividae) Occurs In Animals That Are Fully Withdrawn Into Their Shells, Samantha D. Rupert, Winfried S. Peters Oct 2011

Autotomy Of The Posterior Foot In Agaronia Propatula (Caenogastropoda: Olividae) Occurs In Animals That Are Fully Withdrawn Into Their Shells, Samantha D. Rupert, Winfried S. Peters

Winfried S. Peters

This paper has no abstract; this is the first paragraph. Autotomy is the active shedding of a body part which occurs in a variety of emergency situations including attacks by predators (Stasek, 1967; McVean, 1975; Maginnis, 2006). The immediate advantage of autotomy – surviving an otherwise deadly attack – comes at a price, which may include physical, energetic, behavioural and reproductive costs (Cooper, 2003; Maginnis, 2006). While the evolutionary and ecological consequences of autotomy have been studied most thoroughly in lizards (Clause & Capaldi, 2006; Bateman & Fleming, 2009), the phenomenon also is known from numerous invertebrate taxa, where it involves a wide variety ...
