Testing Alternative Hypotheses For The Cause Of Population Declines: The Case Of The Red-Headed Woodpecker, Walter D. Koenig, Eric L. Walters, Paul G. Rodewald

Biological Sciences Faculty Publications

The Red-headed Woodpecker (Melanerpes erythrocephalus) has experienced strong population declines during the past 3 decades. Using North American Breeding Bird Survey (BBS) and Audubon Christmas Bird Count (CBC) data, we investigated 4 hypotheses that may explain this decline, including: (1) interspecific competition with native Red-bellied Woodpeckers (Melanerpes carolinus) and nonnative European Starlings (Sturnus vulgaris); (2) predation by Cooper's Hawks (Accipiter cooperii) and Sharp-shinned Hawks (Accipiter striatus); (3) climate change; and (4) changes in forested area within their range. In analyses of both the breeding and overwintering periods, our results indicated …

Reproductive Competency And Mitochondrial Variation In Aged Syrian Hamster Oocytes, Fang Li, Frank J. Castora, Wentia Ford, Khalid Alarid, Howard W. Jones Jr., R. James Swanson

Biological Sciences Faculty Publications

The hamster is a useful model of human reproductive biology because its oocytes are similar to those in humans in terms of size and structural stability. In the present study we evaluated fecundity rate, ovarian follicular numbers, ova production, mitochondrial number, structure and function, and cytoplasmic lamellae (CL) in young (2–4 months) and old (12–18 months) Syrian hamsters (Mesocricetus auratus). Young hamsters had higher fertilisation rates and larger litters than old hamsters (100 vs 50% and 9.3 +/- 0.6 vs 5.5 +/- 0.6, respectively). Ovarian tissue from superovulated animals showed a 46% decrease in preantral follicles in old …

Effects Of Cytokine-Induced Killer Cells On Concanavalin-A Induced Hepatitis In Mouse, Warakorn Srisantisuk

Chulalongkorn University Theses and Dissertations (Chula ETD)

Autoimmune hepatitis (AIH) is a chronic inflammatory disease of liver that the pathogenic mechanisms of AIH have not yet been clarified. All patients with AIH lead to cirrhosis and liver cancer. Presently the best feasible medicines of AIH need aid immunosuppressive medications and liver transplantation which have many side effects, high cost and sustained remission. Thus, immunotherapy is an alternative therapy in which cellular material is injected into a patient. Many previous studies showed cytokine induced killer (CIK) cells, T lymphocytes that have a phenotype of NK cells, have a potential to against several diseases associated with liver. The current …

Behavioral And Physiological Assessment Of Zoo-Housed Heterosexual Gorilla (Gorilla Gorilla Gorilla) Troops With Multiple Silverbacks, Kaylin S. Tennant

UNF Graduate Theses and Dissertations

Based on recognized life history traits and ecology, zoos strive to house their gorillas (Gorilla gorilla gorilla) in mixed-sex groups with one mature male or silverback, multiple females, and their offspring. However, successful captive breeding programs and a nearly 50:50 birth sex ratio has created the need to house surplus males in solitary conditions or all-male groups. It is commonly believed that male western gorillas will not tolerate one another in the presence of females; however, multi-male, mixed-sex groups have been observed in the wild. For this reason, some zoos have begun experimenting with this scenario. At the …

Communicating Canine And Human Emotions, Juliane Bräuer, Karine Silva, Stefan R. Schweinberger

Animal Sentience

Kujala (2017) reviews a topic of major relevance for the understanding of the special dog-human relationship: canine emotions (as seen through human social cognition). This commentary draws attention to the communication of emotions within such a particular social context. It highlights challenges that need to be tackled to further advance research on emotional communication, and it calls for new avenues of research. Efforts to disentangle emotional processes from cognitive functioning might be necessary to better comprehend how they contribute, alone and/or in combination, to the communication of emotions. Also, new research methods need to be developed to account for the …

Lemurfaceid: A Face Recognition System To Facilitate Individual Identification Of Lemurs, David Crouse, Rachel L. Jacobs, Zach Richardson, Scott Klum, Anil Jain, Andrea L. Baden, Stacey R. Tecot

Publications and Research

Background: Long-term research of known individuals is critical for understanding the demographic and evolutionary processes that influence natural populations. Current methods for individual identification of many animals include capture and tagging techniques and/or researcher knowledge of natural variation in individual phenotypes. These methods can be costly, time-consuming, and may be impractical for larger-scale, populationlevel studies. Accordingly, for many animal lineages, long-term research projects are often limited to only a few taxa. Lemurs, a mammalian lineage endemic to Madagascar, are no exception. Long-term data needed to address evolutionary questions are lacking for many species. This is, at least in part, due …

The North American River Otter (Lontra Canadensis) On The Department Of Energy's Savannah River Site, Emily B. Mccallen

Masters Theses

The Department of Energy's (DOE) Savannah River Site (SRS) faces a legacy of radionuclide and metal contamination from industrial processes that occurred within the site. The risks posed to ecosystems on the site from contaminants are quantified using the ecological risk assessment process, which often uses the health of a particular species as an ecological endpoint. Northern river otters (Lontra canadensis) are appropriate receptors for studying the effects of long-term, low-level contamination because they are long-lived, higher trophic level organisms likely to accumulate high levels of pollutants. However, little information about river otters on the SRS is known; …

Ontogenetic Changes In Nucleic Acid, Protein Contents, And Growthof Larval And Juvenile Japanese Flounder, Xue Hong Tong, Chengman Bao, Xinhui Tang, Xiaolan Yang, Huanli Wang

Turkish Journal of Zoology

In order to estimate relationships among growth potential and biochemical indicators of Japanese flounder, RNA and DNA as well as protein indices were measured from 5 days after hatching (DAH) to 45 DAH. Results showed that the RNA/DNA ratio and protein/DNA ratio had obvious relations with instantaneous growth rate (GM) and length-based instantaneous growth rate (GL) during the premetamorphic period. Significant negative correlations among protein/DNA ratio and GM and GL were then observed during metamorphosis. During the postmetamorphic phase, the RNA/DNA ratio was positively correlated with GM and GL. Data indicated that body growth of Japanese flounder is mostly hyperplastic …

From 44 different sampled localities of the province of Ordu, we recorded 6 families, 14 genera, and 28 species. Six of these species were previously recorded and 20 of them are new records for Turkey. The results were not surprising, considering that the sampled region had not been studied previously, quite like many habitats in Turkey. With our …

Anatrachyntis Badia (Hodges, 1962) (Lepidoptera: Cosmopterigidae): The First Report From Turkey And A Case Of Importation To Poland, Lukasz Dawidowicz, Robert Rozwa?Ka

Turkish Journal of Zoology

Anatrachyntis badia (Hodges, 1962) (Lepidoptera: Cosmopterigidae) is an opportunistic species native to the southern part of North America. This species was given from several dozens of plants therein from many cultivable plants, such as limes, grapefruits, bananas, peaches, cabbage, blossoms of coconut, Cycas spp., and even pine cones. Thus, it was accidentally introduced to many other countries with appropriate climate with some plants. It can be considered as a plant pest in some cases (e.g., sorghum). The species quite often occurs conjointly with other pest insects, such as mealybug or honeydew moth Cryptoblabes gnidiella (Milliere, 1867) (Lepidoptera: Pyralidae). This paper …

Comparison Of Trophic Structure Of The Benthic Macroinvertebratesin Three Bulgarian Riverine Water Bodies, Maria Kerakova, Yordan Uzunov, Emilia Varadinova

Turkish Journal of Zoology

The trophic structure of benthic macroinvertebrates in three different types of running water bodies subjected to varying degrees of anthropogenic pressure was analyzed. A seasonal survey was conducted at three Bulgarian rivers in 2011. An adapted version of the multihabitat sampling method was applied along with measuring physical and chemical variables. The ecological status was defined by means of biotic and trophic indexes. Distribution of the functional feeding groups shows that the most sensitive groups, shredders and scrapers, dominate the trophic structure of the mountain river types. In contrast, groups of deposit feeders and filterers prevail at the foothill and …

A Comparative Analysis Of Geometric Morphometrics Across Two Pseudemys Turtle Species In East Central Virginia, Kristin C. Dillard

Theses and Dissertations

The phylogeny of the turtle genus Pseudemys is poorly understood. In Virginia, many turtles have been found with indicator traits of both eastern river cooters (Pseudemys concinna concinna) and northern red bellied cooters (Pseudemys rubriventris). This study explores morphological evidence for hybridization between the two species across three riverine sites in east central Virginia.

Museum voucher groups for each species were analyzed for relative shell height and plastron length. The shape of the plastral scutes and upper jaw were analyzed using landmark-based morphometric software. These metrics were compared with measurements taken from 188 field-caught Pseudemys specimens. …
