White-Nose Syndrome And Immune Responses In A Resistant Bat Species (Eptesicus Fuscus), Keslie Skye Naffa Jan 2019

White-Nose Syndrome And Immune Responses In A Resistant Bat Species (Eptesicus Fuscus), Keslie Skye Naffa

Graduate Theses/Dissertations

White-nose syndrome (WNS) has had a large negative impact on bat populations across eastern North America since its arrival in 2006. Bats affected by WNS appear to die of starvation, possibly due to the increased arousals during hibernation when there is no food present to replace the energy used to arouse. During hibernation, the bat’s immune system should be suppressed. However, once a bat of a susceptible species is exposed to the fungus that causes WNS, Psuedogymnoascus destructans (Pd), the immune system seems to respond, potentially causing an elevation in metabolic rate, which may cause the bat to …

Evaluating Spatial Distributions Of Scent-Marks In Semi-Free-Ranging Groups Of Lemur Catta At The Duke Lemur Center, Shallu Prasher Jan 2019

Evaluating Spatial Distributions Of Scent-Marks In Semi-Free-Ranging Groups Of Lemur Catta At The Duke Lemur Center, Shallu Prasher

Graduate Research Theses & Dissertations

Scent-marking is a widespread form of olfactory signaling exhibited in mammals and for a select group of primates. Although research exists on the process of scent-marking, surface preferences, and for the function of scent-marking in lemurs, analyses of how lemur group scent-marking distributions map onto their home range are lacking. The endangered ring-tailed lemur (Lemur catta) deposits scent-marks using its ano-genital, chest, and wrist glands. This project was designed to collect data on two groups of semi-free-ranging captive ring-tailed lemurs at the Duke Lemur Center to first assess how scent-marks are distributed within their home ranges; and second, to evaluate …

Population Health Of Spotted Salamanders (Ambystoma Maculatum) In Created Vernal Pools: An Integrative Approach, Alice R. Millikin Jan 2019

Population Health Of Spotted Salamanders (Ambystoma Maculatum) In Created Vernal Pools: An Integrative Approach, Alice R. Millikin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Habitat creation is an important tool for conservation to counteract habitat loss and degradation. Vernal pools are susceptible to destruction due to limited detection, protection, and regulation. These wetlands provide fishless breeding habitat for many amphibian species including spotted salamanders (Ambystoma maculatum) in eastern North America. Determining whether created vernal pool habitat is successful is often determined by demographic data of colonizing populations. I suggest that hormone levels, population genetics, and disease prevalence can improve our understanding of population health in created habitat. The goal of this dissertation was to assess the health of spotted salamander larvae in …

Distribution And Habitat Use Of Benthic Fishes In The Lower Kanawha River, West Virginia, Nathaniel V. Owens Jan 2019

Distribution And Habitat Use Of Benthic Fishes In The Lower Kanawha River, West Virginia, Nathaniel V. Owens

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Kanawha River in West Virginia is a historically diverse system in terms of ichthyofauna although, like many other large rivers, it has been subjected to a suite of anthropomorphic perturbations. These include this system being modified to allow the passage of commercial vessels for industry thus altering flow regimes, increased sedimentation, water depth, and channelization, and decreased interactions with its floodplain. Additionally, the fishes of this system have suffered from deleterious historical water quality issues caused by intensive timber operations, mining, and industrial waste. Post Clean Air Act, Clean Water Act, and Surface Mining Control and Reclamation Act water …

Spatial Structuring Of Zooplankton Communities Through Partitioning Of Habitat And Resources In The Bay Of Bengal During Spring Intermonsoon, Veronica Fernandes, Nagappa Ramaiah Jan 2019

Spatial Structuring Of Zooplankton Communities Through Partitioning Of Habitat And Resources In The Bay Of Bengal During Spring Intermonsoon, Veronica Fernandes, Nagappa Ramaiah

Turkish Journal of Zoology

Despite advances in oceanographic investigations in the Indian Ocean, zooplankton ecology is still poorly known from the open waters of the Bay of Bengal. In order to understand the vertical and horizontal distribution of zooplankton in the Bay of Bengal during spring intermonsoon, stratified sampling was conducted using a multiple plankton net. We found that higher zooplankton biomass was often associated with mesoscale cold-core eddies. The biomass in the mixed layer was less in the central bay and the near absence of organisms beneath this layer was attributed to the very low dissolved oxygen levels, including suboxia in the northern …

Revision Of The Taxonomic Status Of Rhodanthidium Sticticum Ordonezi (Dusmet, 1915), An Anthidiine Bee Endemic To Morocco (Apoidea: Anthidiini), Max Kasparek, Patrick Lhomme

Turkish Journal of Zoology

Rhodanthidium ordonezi (Dusmet, 1815) is recognized here as a valid species endemic to central and southern Morocco. It has previously been regarded as a subspecies of R. sticticum (Fabricius). The two taxa are in allopatry throughout most of their respective ranges, but probably cooccur in the Middle Atlas Mountains. They are clearly distinguished by their coloration and some aspects of their color patterns. Structural differences are minor, but a multivariate discriminant function analysis of 11 morphometric traits has showed that these are sufficient to assign 82.7% of all specimens correctly. While R. ordonezi has a restricted range in central and …

A Study On European Anchovy (Engraulis Encrasicolus) Swimbladder With Some Considerations On Conventionally Used Target Strength, Meltem Ok, Ali̇ Cemal Gücü

Turkish Journal of Zoology

Hydroacoustic surveys are one of the prime methods to assess the commercially top-ranked small pelagic stocks. The method relies on acoustic scattering from a fish, which is largely controlled by the size and morphology of the swimbladder. In this study, the changes in the size of the European anchovy swimbladder sampled in the Black Sea were investigated. Ventral cross-sectional area (by photographing the ventrally dissected fish) and volume (by dorsal and lateral X-raying) of the swimbladders were estimated. Comparison of areas showed that the stomach fill and presence of viscera did not have a statistically significant impact on the swimbladder …
