“Nuisance” Wildlife Control Trapping: Another Perspective, Brad Gates, John Hadidian, Laura Simon

Wildlife Population Management Collection

Urban wildlife control is a rapidly growing profession in which many practitioners apparently still come from a recreational or commercial trapping background. Perhaps for that reason, much of the “control” in resolving human-wildlife conflicts in cities and suburbs seems to revolve around the use of lethal traps to eliminate “problem” animals. Although some states allow relocation and most apparently allow for nuisance animals to be released on site, the extent to which these practices occur is little known. Further, the biological impacts of continual trapping cycles on urban wildlife populations remain little known as well. An alternative approach to trapping …

Predator Survival Tactics And Use Of Habitat Cover In Rana Catesbeiana., Tara E. Bergin

Undergraduate Research Symposium (UGRS)

Predator-prey relationships are an important aspect of the natural world, and, because of its relevance to survival and natural selection, is an interesting relationship to study. In amphibian larvae, level of activity and landscape use are often what determines the survival as prey. I studied the anti-predator behavior of the North American bullfrog (Rana catesbeiana) tadpoles when presented with dragonfly (Aeshna) larvae, a known predator of tadpoles. Tadpoles were acclimated to four different habitats with varying degrees of habitat cover, and were transferred to a new habitat with a degree of cover equal to one of the acclimation tanks. A …

Predation And Cathemerality. Comparing The Impact Of Predators On The Activity Patterns Of Lemurids And Ceboids., Ian C. Colquhoun

Anthropology Publications

The removal, or absence, of predatory species could be a contributing proximate factor to the rise of primate cathemerality. But predators themselves can also be cathemeral, so cathemerality could well be an evolutionary stable strategy. From a comparative perspective, it appears that the effect of predatory species cannot provide a unitary explanation for cathemerality. Varying distributions and population densities of predators, especially raptors, may be key factors in owl monkey (Aotus) cathemerality, but temperature and lunar cycle variation have also been implicated. In Madagascar, while raptors are potential predators of lemur species, the cathemerality of Eulemur species coincides with that …

Constructed Ponds As Mitigated Habitat For The Wood Frog (Rana Sylvatica Leconte) And The Spotted Salamander (Ambystoma Maculatum Shaw) In West Virginia, Celeste Dawn Good

Theses, Dissertations and Capstones

Many forest dwelling amphibians depend upon aquatic breeding habitats, making them susceptible to habitat changes. To determine if amphibian use of temporary pools occurred, 9 ponds were constructed in 3 forested areas on the MeadWestvaco Wildlife and Ecosystem Research Forest. Studies were conducted in 6 ponds during 2004, and all 9 in 2005 using drift fences. Trapped amphibians were measured and given a pond specific mark with visible implant elastomers. A significant difference was found between low and high elevation sites for juvenile R. sylvatica snout-to-vent length. No significant differences were found for soil, air or water temperatures between sites …

The Breeding Ecology And Natural History Of Ambystomatid Salamanders In An Ephemeral Wetland In Mason County, West Virginia, S. Douglas Kaylor

Theses, Dissertations and Capstones

A forested ephemeral wetland in Mason County, WV, documented to contain 4 of 5 Ambystoma species found in the state, was studied to learn about population sizes, breeding cycles, and habitat use. Minnow traps were placed along three drift fences with additional traps placed throughout the study area. From February 5 to March 27, 2005, 85 captured adults were identified to species, marked by elastomer injection for mark-recapture analysis, and measured for morphometrics. Larval salamanders were identified, staged, measured, and returned. Egg clutches were mapped and counted. Mark-recapture analysis suggests the A. texanum population size is between 635 and 735 …

Survey Of The Great Kanawha River, West Virginia, For Virulence Related Gene Markers Stx1, Stx2, And Eaea, Christina Carole Johnson

Theses, Dissertations and Capstones

Microbial surveying using antibiotic resistant bacteria, fecal coliforms, and virulence genes is an approach not previously tested on the Great Kanawha River. Research objectives were to test antibiotic resistant and fecal coliform bacteria as bioindicators of water quality, and develop a multiplex- polymerase chain reaction (mPCR) system for identification of stx1, stx2, and eaeA DNA sequences in isolated fecal coliforms (FC). Fecal indicator populations and antibiotic resistant populations were demonstrated to be independent. Bacterial populations were assigned impact score(s) (IS) values for each sample site based on data set percent ranks. Population scores were summed per sample site to generate …

The Southern Family Farm As Endangered Species: Possibilities For Survival In Barbara Kingsolver's Prodigal Summer, Suzanne W. Jones

English Faculty Publications

At the same time some southern studies scholars are positioning the U.S. South in a larger cultural, historic, and economic region that encompasses the Caribbean and Latin America, some southern environmentalist writers, such as long-time essayist and novelist Wendell Berry and activist-turned-memoirist Janisse Ray, are finding a pressing need to focus on smaller bioregions and the locatedness of the human subject. These writers believe that agribusiness and consumer ignorance are driving small farmers out of business and that clear-cutting timber and farming practices dependent on chemicals are threatening local ecosystems. Best-selling novelist Barbara Kingsolver has joined their ranks. With her …

An Examination Of Agonistic Interactions In The Whip Spider Phrynus Marginemaculatus (Arachnida, Amblypygi), Kasey D. Fowler-Finn, Eileen Hebets

Eileen Hebets Publications

Intraspecific interactions in adult whip spiders (Phrynus marginemaculatus) were investigated in a laboratory setting to quantify agonistic interactions and to determine predictors of contest outcome. Males were initially paired with size-symmetric or size-asymmetric opponents to assess the effect of size symmetry on contests. Three weeks later, the same males were paired with either the same opponent, or a different opponent to determine whether or not individuals remember earlier encounters. Finally, we quantified aspects of female-female contests. Agonistic encounters between males are characterized by varying degrees of pedipalpal opening, elevation displays, and rapid flicking (~ 29 Hz) of the …

Decreased Reproductive Investment Of Female Threespine Stickleback Gasterosteus Aculeatus Infected With The Cestode Schistocephalus Solidus: Parasite Adaptation, Host Adaptation, Or Side Effect?, Eric T. Schultz, Michelle Topper, David C. Heins

EEB Articles

Parasitic infections may cause alterations in host life history, including changes in reproductive investment (absolute amount of energy allocated to reproduction) and reproductive effort (proportion of available energy allocated to reproduction). Such changes in host life history may reflect: 1) a parasite tactic: the parasite adaptively manipulates energy flow within the host so that the host is induced to make a reduction in reproductive effort and reproductive investment, making more energy available to the parasite; 2) no tactic: there is no change in host reproductive effort and reproductive investment simply decreases as a side effect of the parasite depleting host …

Sub-Lethal Effects Of 2,4-D Exposure On Golf Course Amphibians, Travis J. Ryan, Catherine M. Scott, Brooke A. Douthitt

Scholarship and Professional Work - LAS

Amphibians are among the most common vertebrates inhabiting golf courses. They are frequent inhabitants of golf course wetlands, where they are likely to be episodically exposed to small quantities of herbicides in proper golf course maintenance. The goal of this study was to investigate whether amphibian larvae subjected to sublethal concentrations of a common herbicide used in golf course maintenance would likely result in significant life history, locomotor, or behavioral effects (e.g., changes in growth, swimming speed, or feeding ability). For these experiments we selected as models tadpoles of the southern leopard frog (Rana sphenocephala) and the herbicide 2,4- dichlorophenoxyacetic …

Differential Habituation Of Male Betta Splendens To Qualitatively Different Stimuli, Lauren Baard

Undergraduate Research Symposium (UGRS)

Habituation is a learning mechanism that functions to decrease the amount of energy and attention focused on a certain stimuli. Male Siamese Fighting Fish, Betta splendens, are territorial animals that defend their territories using a number of aggressive displays. Male Bettas have previously shown the ability to habituate to the presence of a conspecific male when visually exposed to each other. Due to the costly nature of many of the male Betta’s displays, I hypothesized that male Bettas should differentially habituate to qualitatively different stimuli. I presented each of three groups of male Betta splendens with a different stimulus, each …

Ichthyofaunal Assemblages In Three Approximate But Ecologically Diverse Streams In Clark County, Arkansas, C. Renn Tumlison, Scott Jordan, Lesley Self, Henry W. Robison

Journal of the Arkansas Academy of Science

Three tributaries to the Ouachita River in eastern Clark County, Arkansas, empty into the river within a collective distance of about 9 km. The streams drain basins derived from the Wilcox formation, partially overlain by terrace and alluvial deposits. Despite their proximity, the streams are very different: L'Eau Frais has a gravel substrate and was recognized by the French as a cool water stream, Tupelo Creek is a bottomland stream from which numerous Water Tupelo (Nyssa aquatica) emerge, and Saline Bayou was named due to its marked salinity. We studied the assemblages of fishes in these 3 very different drainages …

Biological Sciences Faculty Research

We describe the edopoid temnospondyl Nigerpeton ricqlesi from the Upper Permian Moradi Formation of northern Niger on the basis of two partial skulls and tentatively associated postcranial material. This crocodile-like taxon displays several edopoid characters states such as a long prenarial region with enlarged premaxillae, elongated vomers, large, posteriorly tapering choanae, and a jugal that broadens anteriorly. Nigerpeton possesses a unique carnivorous dentition. It is autapomorphic in its possession of an extremely elongate snout bearing a maxillary bulge that accommodates three hypertrophied caniniform teeth, inner premaxillary tusks, and anterior paired fenestrae, which pierce the skull roof. In addition, both the …

The Winter Ecology Of The Piping Plover (Charadrius Melodus) In Coastal Georgia, Brandon Lennon Noel

College of Graduate Studies: Theses & Dissertations

Author's abstract: The Piping Plover (Charadrius melodus) is a federally listed species with three distinct breeding populations, including Great Plains (threatened), Great Lakes (endangered), and Atlantic Coast (threatened), all of which winter along the Atlnatic and Gulf coasts of the United States. I studied the winter ecology of the Piping Plovers on Little St. Simons Island (LSSI), Georgia, from 2003-2006, with emphasis on the conservation significance of this site for the endangered Great Lakes population. During 2003-2004 and 2004-2005, LSSI supported up to 100 Piping Plovers during peak migration, and approximately 40 birds wintered at this site. All populations had …

3-Pg Productivity Modeling Of Regenerating Amazon Forests: Climate Sensitivity And Comparison With Modis-Derived Npp, Joseph D. White, Neal A. Scott, Adam I. Hirsch, Steven W. Running

Ecosystem and Conservation Sciences Faculty Publications

Potential forest growth predicted by the Physiological Principles in Predicting Growth (3-PG) model was compared for forest and deforested areas in the Legal Amazon to assess potential differing regeneration associated with climate. Historical deforestation and regeneration have occurred in environmentally marginal areas that influence regional carbon sequestration estimates. Effects of El Niño–induced drought further reduce simulated production by decreasing soil water availability in areas with shallow soils and high transpiration potential. The model was calibrated through comparison of literature biomass and with satellite-based estimates. Net primary productivity (NPP) for mature Amazonian forests from the 3-PG model was positively correlated ( …

Geographic Distribution And Harvest Dynamics Of The Eastern Spotted Skunk In Arkansas, D. Blake Sasse, Matthew E. Gompper

Journal of the Arkansas Academy of Science

The eastern spotted skunk (Spilogale putorius) is a small carnivore found across much of the central and southeastern United States, and while once common, this species has become rare in most obits range. We used harvest records collected by the Arkansas Game and Fish Commission from 1941-2004 to examine historic and current distribution and long-term harvest dynamics of this species in Arkansas. Eastern spotted skunks have historically been most common in the Ozarks and the Ouachitas though the species appears to have been present, but uncommon, in the Gulf Coastal Plain and in some counties in southeastern Arkansas near the …

Estimating Consumption Rates Of Juvenile Sandbar Sharks (Carcharhinus Plumbeus) In Chesapeake Bay, Virginia, Using A Bioenergetics Model, W. Wesley Dowd, Richard W. Brill, Peter G. Bushnell, John A. Musick

Biology Faculty Works

Using a bioenergetics model, we estimated daily ration and seasonal prey consumption rates for six age classes of juvenile sandbar sharks (Carcharhinus plumbeus) in the lower Chesapeake Bay summer nursery area. The model, incorporating habitat and species-specific data on growth rates, metabolic rate, diet composition, water temperature (range 16.8−27.9°C), and population structure, predicted mean daily rations between 2.17 ±0.03 (age-0) and 1.30 ±0.02 (age-5) % body mass/day. These daily rations are higher than earlier predictions for sandbar sharks but are comparable to those for ecologically similar shark species. The total nursery population of sandbar sharks was predicted to consume ~124,000 …

Urine-Marking And Ground-Scratching By Free-Ranging Arctic Wolves, Canis Lupus Arctos, In Summer, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Urine-marking and ground-scratching were observed in an Arctic Wolf (Canis lupus) pack on Ellesmere Island, Nunavut, Canada, during 16 summers between 1986 and 2005. All previously known urination postures and ground-scratching by breeding males and females were seen, and incidence of marking and scratching was greatest when non-pack wolves were present. Observations of urine-marking of food remains supported the conclusion from a captive Wolf study that such marking signals lack of edible food.

Interference Effects In The Memory For Serially Presented Locations In Clark’S Nutcrackers, Nucifraga Columbiana, Jody L. Lewis, Alan C. Kamil

Papers in Behavior in Biological Sciences

The authors tested the spatial memory of serially presented locations in Clark’s nutcrackers (Nucifraga columbiana). Birds were serially presented with locations in an open room. The authors buried a seed in a sand-filled cup at each location and then tested nutcrackers for their memory for each location in the list by using the cluster method. For each item in the list, the authors opened a cluster of 6 holes. Accuracy was measured by how many tries were required for the bird to find the correct location within each cluster. In Experiments 1 and 2, the authors presented 2 …

Social Play In Kakapo (Strigops Habroptilus) With Comparisons To Kea (Nestor Notabilis) And Kaka (Nestor Meridionalis), Judy Diamond, Daryl Eason, Clio Reid, Alan B. Bond

Papers in Behavior in Biological Sciences

The play behavior of the critically endangered kakapo (Strigops habroptilus; Aves: Psittaciformes: Psittacidae) is here compared to that of its closest relatives, the kea (Nestor notabilis) and the kaka (Nestor meridionalis). Contrasting kakapos, which are relatively solitary, with the more social Nestor parrots provides an attractive test of the relative contributions of phylogeny and sociality to the evolution of play. Overlapping cluster analysis of play sequences using a hypergeometric similarity metric indicated that kakapo play is generally less complex, lacking the intensity, duration, structure, and reciprocity of play in the Nestor parrots. Kakapos have …

Selective Attention, Priming, And Foraging Behavior, Alan Kamil, Alan B. Bond

Papers in Behavior in Biological Sciences

Animals selectively filter and transform their sensory input, increasing the accuracy with which some stimuli are detected and effectively ignoring others. This filtering process, collectively referred to as “selective attention,” takes place at a variety of different levels in the nervous system. It was described in considerable detail by William James over a century ago (James, 1890/1950) and has been a principal focus of research in cognitive psychology for nearly 50 years (Parasuraman & Davies, 1984; Pashler, 1998; Richards, 1998). Investigations of selective attention have also been central to the study of animal cognition, where the process of attention has …
