Microhabitat Comparison Of Percina Roanoka (Roanoke Darter) And Percina Nevisense (Chainback Darter) In The Roanoke River, Dakota R. Spruill, Steven L. Powers Apr 2019

Microhabitat Comparison Of Percina Roanoka (Roanoke Darter) And Percina Nevisense (Chainback Darter) In The Roanoke River, Dakota R. Spruill, Steven L. Powers

Virginia Journal of Science

Snorkel observations of Percina roanoka and P. nevisense in the Roanoke River during summer months were followed by measuring current velocity, water depth, and substrate diameter at points of occupation. A total of 89 observations of P. roanoka and 81 observations of P. nevisense were compared using two-sample T-tests. Percina roanoka inhabited faster, shallower water than P. nevisense with the former found in a mean flow of 0.318 m/s and depth of 31.53 cm and the latter in a mean flow of 0.17 m/s and depth of 55.6 cm. Mean diameter of substrate at points of occupation did not …


Morphological And Color Variation In Poicephalus Parrots, Eileen Connon Apr 2019

Morphological And Color Variation In Poicephalus Parrots, Eileen Connon

Undergraduate Honors Thesis Projects

Though describing and delimiting species is one of the principle aspects of many disciplines within biology, there is often debate about which methods and concepts should be used to make such decisions. The Tobias criteria for quantitative species delimitation represent one attempt to create a standard method of delimiting species based on the morphological species concept. However, previous examples of using these criteria have not always been completely quantitative. This study uses quantitative morphological and color data of three Poicephalusparrots as a case study for the effectiveness of the Tobias criteria. The results show varying levels of support for …

This report will describe the process of developing this program as well as it’s implementation and outcomes. In addition, it includes a review of scholarly literature on …


The Role Of Inflammatory Pathways In Development, Growth, And Metabolism Of Skeletal Muscle In Iugr Offspring: Blood Gene Expression Of Inflammatory Factors As Novel Biomarkers For Assessing Stress And Wellbeing In Exotic Species, Robert J. Posont Apr 2019

The Role Of Inflammatory Pathways In Development, Growth, And Metabolism Of Skeletal Muscle In Iugr Offspring: Blood Gene Expression Of Inflammatory Factors As Novel Biomarkers For Assessing Stress And Wellbeing In Exotic Species, Robert J. Posont

Department of Animal Science: Dissertations, Theses, and Student Research

Our first study identified the effects of maternal inflammation-induced intrauterine growth restriction (MI-IUGR) on growth and muscle glucose metabolism in offspring supplemented with curcumin. MI-IUGR lambs exhibited asymmetric growth restriction at birth and 30d of age, but normal glucose-stimulated insulin secretion. Hindlimb glucose oxidation was reduced by MI-IUGR and not improved by curcumin supplementation. Ex vivo muscle glucose oxidation was reduced by MI-IUGR but improved somewhat by curcumin. These finding indicate that fetal programming responses to MI contribute to neonatal growth and metabolic deficits. Neonatal curcumin supplementation had minimal effect on growth deficits but may improve glucose metabolism. …


The Relationship Between Coat Color And Dominance In Female Sable Antelope Over Time, Taylor Wilson Apr 2019

The Relationship Between Coat Color And Dominance In Female Sable Antelope Over Time, Taylor Wilson

Undergraduate Honors Thesis Projects

Sable antelope (Hippotragus niger)exhibit sexual dimorphism, where males and females look different from each other in color and size. Within this difference between the sexes, there are a wide spectrum in coat colors among females, ranging from light tan to dark brown. The variations seen in female coat color in other species are known to be hormonally caused by testosterone. Testosterone levels are also related to dominance within the herd in other species. The first objective of this study is to determine if the variations in coat color are associated with the dominance hierarchy among female sable …


Impact Of Intrinsic Physiological Factors In The Population Recovery Of Myotis Lucifugus (Little Brown Myotis) From White-Nose Syndrome, Caroline Burke, Caitlin Looney, Alissah Sillah, Christopher Richardson Mar 2019

Impact Of Intrinsic Physiological Factors In The Population Recovery Of Myotis Lucifugus (Little Brown Myotis) From White-Nose Syndrome, Caroline Burke, Caitlin Looney, Alissah Sillah, Christopher Richardson

Lesley University Community of Scholars Day

White-nose Syndrome (WNS) has decimated populations of hibernating bats in the US. In particular, Myotis lucifugus (little brown myotis) has been one of the most affected. We investigated the energetic cost of innate immune response and Pseudogymnoascus destructans (Pd) fungal activity on post-hibernating little brown myotis and the link with the recovery of local populations in New England from WNS. We captured bats at one of each of 4 colonies in Eastern Massachusetts and Southern New Hampshire, consecutively, every 14 days to minimize disturbance to the colony. Blood samples were collected from each bat. Respirometry trials were performed on each …


The Effect Of Social Hierarchy On Behavior In Cercopithecus Petaurista, Mason Reinhart Mar 2019

The Effect Of Social Hierarchy On Behavior In Cercopithecus Petaurista, Mason Reinhart

The Pegasus Review: UCF Undergraduate Research Journal

The social group hierarchy of three captive C. petaurista specimens was monitored and determined by observing agnostic fights, aggression, and allogrooming incidents. This social group was monitored from May to August in 2017 for 60.5 observation hours total as a continuation of a previous study conducted in spring of 2017. The study took place at the Central Florida Zoo and Botanical Gardens. All observations were recorded on template sheets with the location of each individual noted on a 6x6 grid representing the enclosure. A new sheet was used for each 15-minute increment during observation periods. It was concluded that agnostic …


The Brothers: A Study Of The Social Structure Between Two Captive Cheetahs, Chenienne Clemens Mar 2019

The Brothers: A Study Of The Social Structure Between Two Captive Cheetahs, Chenienne Clemens

The Pegasus Review: UCF Undergraduate Research Journal

Cheetahs (Acinonyx jubatus) are easily differentiated among other Felids. They exhibit unique physiological features, and their type of social structure has not been seen in any other species of Felid. Coalitions of male cheetahs are seen both in the wild and in captivity, while female cheetahs remain solitary. This paper is a compilation of a twelve-week observational study of the two male cheetahs at the Central Florida Zoo in Sanford, Florida. The focus of the study was the social structure between the two related individuals. The observational data showed that there is a lack of any hierarchy or …


Breeding Record Of The Hooded Vulture Necrosyrtes Monachus (Timminek, 1823) At Emi Abumo Woro, Kogi State, Nigeria, K. L. Adang, D. Tanko, K. L. Saliu, Umarfarooq Abdulwahab Mar 2019

Breeding Record Of The Hooded Vulture Necrosyrtes Monachus (Timminek, 1823) At Emi Abumo Woro, Kogi State, Nigeria, K. L. Adang, D. Tanko, K. L. Saliu, Umarfarooq Abdulwahab

Watershed Sciences Student Research

The hooded vulture Necrosyrtes monachus is a critically endangered species and recently published evidence suggests that its population is experiencing an extremely rapid decline, owing to indiscriminate poisoning, trade for traditional medicine, hunting, persecution, electrocution, habitat loss and degradation. As a result of these threats, the species is gradually disappearing from its range and thus, the sighting of vultures or their nests is becoming very rare. This paper thus, presents a report on the sighting of the Hooded Vulture and its nest at Emi Abumo Woro Village, Kogi State, Nigeria. This is an evident and equally an indication that Emi …


Assessment Of Wildlife Rehabilitation Trends: Domestic Dog And Cat Attacks, Rachel Wilson Mar 2019

Assessment Of Wildlife Rehabilitation Trends: Domestic Dog And Cat Attacks, Rachel Wilson

Undergraduate Honors Thesis Projects

Human-wildlife conflict is a growing concern, and domestic cat predation is estimated to be responsible for billions of wildlife deaths every year in the Unites States. Domestic dog predation has been less well studied, but as dogs are the second most numerous pet in the U.S. after cats, their impact on native wildlife should also be assessed. One method to assess domestic animal predation is to examine trends in wildlife rehabilitation records. Using the online database WILD-ONe, I analyzed over 31,000 wildlife hospital records in the United States from 2011-2016. During this time span, data showed over 14,000 domestic dog …


Improving Risk Assessment Of The Emergence Of Novel Influenza A Viruses By Incorporating Environmental Surveillance, Kim M. Pepin, Matthew W. Hopken, Susan A. Shriner, Erica Spackman, Zaid Abdo, Colin Parrish, Steven Steven, James O. Lloyd-Smith, Antoinette J. Piaggio Mar 2019

Improving Risk Assessment Of The Emergence Of Novel Influenza A Viruses By Incorporating Environmental Surveillance, Kim M. Pepin, Matthew W. Hopken, Susan A. Shriner, Erica Spackman, Zaid Abdo, Colin Parrish, Steven Steven, James O. Lloyd-Smith, Antoinette J. Piaggio

United States Department of Agriculture Wildlife Services: Staff Publications

Reassortment is an evolutionary mechanism by which influenza A viruses (IAV) generate genetic novelty. Reassortment is an important driver of host jumps and is widespread according to retrospective surveillance studies.However, predicting the epidemiological risk of reassortant emergence in novel hosts from surveillance data remains challenging. IAV strains persist and cooccur in the environment, promoting co-infection during environmental transmission. These conditions offer opportunity to understand reassortant emergence in reservoir and spillover hosts. Specifically, environmental RNA could provide rich information for understanding the evolutionary ecology of segmented viruses, and transform our ability to quantify epidemiological risk to spillover hosts. However, significant challenges …

An Endemic Species In A Protected Area: Euscorpius Carpathicus (L., 1767) In The Cozia National Park, Romania (Scorpiones: Euscorpiidae), Severus-Daniel Covaciu-Marcov, Sára Ferenţi

Euscorpius

In 2016-2018, we identified 48 distribution records of Euscorpius carpathicus in the Cozia National Park, from the Romanian Southern Carpathians. The Carpathian scorpion was found between 300 and 847 m a.s.l., in forested regions, being more numerous in the lower areas situated along the Olt River. E. carpathicus is a native species in the region; it populates natural areas with low human impact.


Alternative Nad(P)H Dehydrogenase And Alternative Oxidase: Proposed Physiological Roles In Animals, Allison Mcdonald, Dmytro V. Gospodaryov Mar 2019

Alternative Nad(P)H Dehydrogenase And Alternative Oxidase: Proposed Physiological Roles In Animals, Allison Mcdonald, Dmytro V. Gospodaryov

Biology Faculty Publications

The electron transport systems in mitochondria of many organisms contain alternative respiratory enzymes distinct from those of the canonical respiratory system depicted in textbooks. Two of these enzymes, the alternative NADH dehydrogenase and the alternative oxidase, were of interest to a limited circle of researchers until they were envisioned as gene therapy tools for mitochondrial disease treatment. Recently, these enzymes were discovered in several animals. Here, we analyse the functioning of alternative NADH dehydrogenases and oxidases in different organisms. We propose that both enzymes ensure bioenergetic and metabolic flexibility during environmental transitions or other conditions which may compromise the operation …

Natology Collection

Canine dystocia is a relatively common veterinary presentation. First opinion emergency care clinical data from 50 Vets Now clinics across the UK were used to explore dystocia management and outcomes in bitches. Caesarean section (CS) was performed on 341/701 (48.6 per cent (95 per cent CI 44.9 to 52.4)) of dystocia cases. The bulldog (OR 7.60, 95 per cent CI 1.51 to 38.26, P=0.014), Border terrier (OR 4.89, 95 per cent CI 0.92 to 25.97, P=0.063) and golden retriever (OR 4.07, 95 per cent CI 0.97 to 17.07, P=0.055) had the highest odds of CS among dystocic bitches compared with …

2018-2019 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Eighteen counts were held during the 2018-19 Christmas Bird Count season. This is two more than were done last season, which was the first time that as many as sixteen counts were held. This year no counts were postponed or cancelled, and the Beaver Valley Count was revived after a four year hiatus. Twelve of the counts were done during the first week of the count period. While the conditions for these early counts were mild and dry, heavy precipitation in late fall coupled with an early onset of cold weather in the first part of December resulted in little …

Winter Field Report, December 2018 To February 2019, W. Ross Silcock

Nebraska Bird Review

As has been the trend in recent winters, and despite the relative coolness of this winter, there were numerous examples of species north of expected midwinter ranges or present in higher numbers than usual in winter. The long list includes unexpected midwinter records of Tundra Swan, American Wigeon, Ring-necked Duck, Lesser Scaup, White-winged Dove, Sandhill Crane, Clark’s Grebe, Doublecrested Cormorant, Red-shouldered Hawk, and Yellow-bellied Sapsucker. Startling was the state’s first winter record of Sedge Wren, perhaps the biggest rarity of the season. And Eastern Meadowlark was documented in midwinter for the first time, although its presence in the southeast has …


Dolphins In Space: Quantifying The Relative Positions Of Bottlenose Dolphins (Tursiops Truncatus), Megan S. Mcgrath Feb 2019

Dolphins In Space: Quantifying The Relative Positions Of Bottlenose Dolphins (Tursiops Truncatus), Megan S. Mcgrath

Theses and Dissertations

Bottlenose dolphins (Tursiops truncatus) are socially sophisticated mammals with high fission-fusion dynamics and complex communication. The relative positioning of individual dolphins as they swim within their social group may aid in the expression of social roles. This study sought to quantify relative positioning in a small social group of female bottlenose dolphins at the National Aquarium in Baltimore that included two mother-daughter pairs, maternal and paternal half-sisters, a half-aunt and niece, and one unrelated female. We devised a method for scoring relative positioning in three dimensions. We found that the two mothers and their juvenile and adult daughters …

The Influence Of Pointing Accuracy In An Object-Choice Task With Domestic Horses (Equus Caballus), Elizabeth A. Krisch

Theses and Dissertations

This study evaluated the influence of pointing accuracy and experimenter identity on domestic horse (Equus caballus) behavior in an object-choice task. Results suggest that after receiving inaccurate pointing cues, horses adapt their responses based on their familiarity with an experimenter, and exhibit signs of memory retention across test trials.


The Morphology And Evolution Of The Primate Brachial Plexus, Brian M. Shearer Feb 2019

The Morphology And Evolution Of The Primate Brachial Plexus, Brian M. Shearer

Dissertations, Theses, and Capstone Projects

Primate evolutionary history is inexorably linked to the evolution of a broad array of locomotor adaptations that have facilitated the clade’s invasion of new niches. Researchers studying the evolution of primates and of their individual locomotor adaptations have traditionally relied on bony morphology – a practical choice given the virtual non-existence of any other type of tissue in the fossil record. However, this focus downplays the potential importance of the many other structures involved in locomotion, such as muscle, cartilage, and neural tissue, which may each be influenced by separate selective forces because of their different roles in facilitating movement. …


Habitat Usage Patterns Of Bottlenose Dolphins (Tursiops Truncatus) In Terrebonne And Timbalier Bays, Louisiana, Mary Allison Manning Jan 2019

Habitat Usage Patterns Of Bottlenose Dolphins (Tursiops Truncatus) In Terrebonne And Timbalier Bays, Louisiana, Mary Allison Manning

LSU Master's Theses

I coupled fine-scale environmental data with observed behavior and group composition data to examine overall distribution within the bay system and to characterize the habitat associated with foraging and the presence of calves. Semi-isolated populations of bottlenose dolphins (Tursiops truncatus) along Louisiana’s coast are undergoing increased risks from boat traffic, oil spills, land subsidence, and planned water diversions (CPRA 2017). Characterizing the habitat use of bottlenose dolphins in Terrebonne and Timbalier bays, Louisiana, is important given the likely high site fidelity, small home ranges, and low exchange of individuals with nearby coastal populations (Lane et al. 2015, McDonald …

A New Semidesert Microtityus Kjellesvig-Waering, 1966 (Scorpiones: Buthidae) From Southeast Cuba, Greater Antilles., Rolando Teruel

Euscorpius

A new species of the buthid scorpion genus Microtityus Kjellesvig-Waering, 1966, is herein described from specimens of both sexes collected at three nearby localities in the western part of the Guantánamo Bay Area, southeast Cuba. It belongs in the "jaumei" species-group of the subgenus Microtityus (Parvabsonus) Armas, 1974 and is very peculiar not only by its external morphology (very distinct from its other Cuban congeners), but also by the unusual habitat where it occurs in and seems to be restricted to (dry and hot cactus scrub on volcanic sandy plain). The present contribution reinforces the position of this genus as …
