Correlation Between Abundance Of Fossils In Harvester Ant Nest And Proximity Of Fossil Sites, Hayeong Woo

Campus Research Month

Harvester ants have an interesting behavior of bone collecting. Therefore, harvester ant nests that are positioned around the fossil sites contain various fossil fragments. If there is a statistically significant correlation between the abundance of fossil fragments and the distance of the ant nests from the main fossil sites, ant nests can potentially be used to predict the proximity of the main fossil sites.

Impact Of Whitetail Deer Overpopulation With Hunting On The Decline, Matthew J. Lamprinos

English Department: Research for Change - Wicked Problems in Our World

The whitetail deer is a key species for Pennsylvania’s forests, but their ecological balance has been disturbed by unregulated growth and urban sprawl. The deer population in Pennsylvania has exploded since the 1880’s causing a wide range of damage on the ecosystem, and humans. To reduce deer populations to sustainable levels, the Pennsylvania Game Commission relies heavily on hunters to dedicate time in the fall to go out and fill the tags the they issue. Hunter participation all around the world is decreasing for a variety of reasons. Fewer hunters out in the field causes revenue losses for the Game …

Effect Of Supplemental Garlic On The Incidence Of Anemia In Horses, Victoria Willis

Masters Theses & Specialist Projects

Garlic (Allium sativum L.) is a spice that has been used for centuries for medicinal purposes or flavoring in food. Garlic has also been commonly used as a fly and pest control for horses and is still commonly used for that purpose today. Recent research has shown garlic may cause Heinz body anemia in horses. The purpose of this study was to evaluate the incidence of Heinz body anemia in horses supplemented with varying rates of garlic. This study included 12 horses divided into 4 groups (control and 3 supplement rates: low (0.0625 g/kg), medium (0.125 g/kg), high (0.1875 g/kg)) …

Emotional Support Animals For College Students: Do The Benefits Outweigh The Costs?, Sidney Street

Undergraduate Honors Thesis Projects

Mental health problems have been drastically increasing in recent years among college students. Alongside the rising prevalence of psychological distress, universities have also experienced an increase in requests to have Emotional Support Animals (ESAs) live on campus. To date however, data are scarce on students’ experiences living with and around ESAs. The present study aims to investigate attitudes and perceptions about ESAs, in both owners of ESAs as well as students who do not own an ESA but have interacted with one. Specifically, owners were interviewed to find whether the perceived benefits of owning an ESA outweigh the associated costs …

A Macro Analysis Of Illegal Hunting And Fishing Across Texas Counties: Using An Economic Structural Approach, Leo J. Genco Jr.

USF Tampa Graduate Theses and Dissertations

The purpose of this disseration is to examine the distribution of illegal hunting and fishing violations across Texas counties in respect to the economic structure. Illegal hunting plays a part in the extraction of resources that are overly withdrawn, and criminologists have ignored this form of deviancy that has large ramifications for the environment. To view this criminal phenomenon, the study uses the Treadmill of Production theory to determine economic structural factors and whether those factors explain the distribution of illegal hunting and fishing. Using regression analyses and SatScan, the findings suggested that while there are significant factors related to …

Standardized Ileal Digestibility Of Amino Acids In Nacedero (Trichanthera Gigantea (Humboldt & Bonpland.) Nees) Foliage, Copra Expeller, And Soybean Meal Fed To Growing Philippine Native Pigs (Sus Scrofa Domesticus Erxleben, 1777), Mary Arnel D. Garcia, Rommel C. Sulabo

The Philippine Agricultural Scientist

The experiment was conducted to determine the apparent ileal digestibility (AID) and standardized ileal digestibility (SID) of amino acids (AA) in nacedero (Trichanthera gigantea Humboldt & Bonpland.) Nees; NAC) foliage, copra expeller (CE), and soybean meal (SBM) fed to growing Philippine native pigs (Sus scrofa domesticus Erxleben, 1777). Eight barrows of Black Tiaong strain (initial BW of 36.44 ± 1.59 kg; 132 to 135 d) installed with a T-cannula at the distal ileum were housed individually in metabolism cages and randomly allotted to a replicated 4 × 3 Youden square design with four diets and three periods. One …

Morph- And Sex-Specific Differences In Corticosterone Of The Arizona Tiger Salamander (Ambystoma Mavortium Nebulosum), Megan Zerger

Scholars Week

Life history morph, sex, and body condition are traits that may influence stress within salamander populations because of differences in physiology and environmental conditions. Given widespread declines and the effects chronic stress can have on amphibian health, it is important to understand within-population drivers of stress and how population level variation may influence population viability. Thus, the objective of our study was to assess how corticosterone varies within the Arizona tiger salamander (Ambystoma mavortium nebulosum) population at the Mexican Cut Nature Preserve. We used a non-invasive skin swabbing method to collect baseline and elevated corticosterone from paedomorph (aquatic …

Understanding Relationships Between Stress, Snake Fungal Disease, And Parasitism In Wild Cottonmouth Snake Populations, Emma Fehlker Campbell

Scholars Week

Chronically raised stress levels are known to correlate with decreased immune function in vertebrates, possible leading to increased susceptibility to infections including parasitism and Snake Fungal Disease (SFD). Helminth endoparasites and Hemoparasites are frequently found in wild populations but little is known about their physiological effects. Additionally, parasite infection may have interactive effects with diseases including SFD. To our knowledge few studies have assessed potential interactions between SFD and parasites in snakes. Thus, the objective of our study is to assess the individual and interactive effects of Helminth endoparasites, hemoparasites, and snake fungal disease on cottonmouth physiological stress. We are …

Comparison Of Gray Squirrel (Sciurus Carolinensis) And Fox Squirrel (Sciurus Niger) In Order To Explore Genes That Confer A Fitness Advantage, Joshua Franzen

UNO Student Research and Creative Activity Fair

Mutations in the MC1R gene is associated with melanism, or black fur, and the presence of a 24 base pair deletion in the MC1R gene of fox and gray squirrels suggests a shared ancestry between the two species. This could be due to a mutation in a common ancestor or previous mating between species. Evidence has shown that the most likely cause for the presence of MC1R in both species is previous mating between species. If this did occur, then it is possible that other genes traveled between species along with the mutated MC1R gene. Conserved genes shared between species …

Holocene Records Of Nebraska Mammals, Hugh H. Genoways

Zea E-Books Collection

A survey of the archeological and paleontological literature allowed a compilation of Holocene records of mammals in Nebraska. This survey identified Holocene records from 338 sites in 62 of the 93 Nebraska counties. These counties were located throughout state, but there was a concentration of sites in southwestern Nebraska where there were 27 fossil sites in Frontier County and 22 in Harlan County. Fossils sites were underrepresented in the Sand Hills region. Records of fossil mammals covered the entire Holocene period from 13,000 years ago until AD 1850. A minimum of 57 species (with eight additional species potentially present) representing …

Phenology Of Antler Casting And Occurrence Of Late-Breeding In Nebraska White-Tailed Deer, Brian C. Peterson, Patrick D. Farrell, Dave Fehlhafer, Miranda C. Reinson, Dustin H. Ranglack

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

White-tailed deer (Odocoileus virginianus) in Nebraska primarily breed in November (stimulated by photoperiod), but this season extends into December and January for unfertilized females and healthy fawns reaching the appropriate breeding weight by winter. Variation in the typical mating period can be attributed to geographic region, skewed sex ratios, and fawns reaching sexual maturity during their first year of birth. During April of 2019, we observed late season breeding by a male white-tailed deer in the central Platte River valley and documented late antler casting for this same late-copulating male. An additional male was observed in April of …

Monitoring For Wolves, Jeff Hansen, Cat Urbigkit

Wildlife Damage Management Technical Series

Gray wolves (Canis lupus) and Mexican wolves (Canis lupus baileyi) once again roam across landscapes where they have been absent for decades (Figure 1). With wolf range expansion comes increased opportunities for conflicts when wolves harass or prey on domestic livestock or other animals. Wolves have relatively high reproductive and dispersal rates but detecting individual animals in low-density populations is difficult without a concerted monitoring effort. In fact, wolf presence in an area often is not known until there is a confirmed livestock depredation. Ranchers and wildlife damage management experts need not wait for livestock depredations to occur before wolves …

Data Repository For "North American Porcupine Distribution In The Pacific Northwest And Evaluation Of A Non-Invasive Monitoring Technique", Cara L. Appel, Katie M. Moriarty, Sean M. Matthews, David S. Green, Stacy Anderson, Evan King, J Scott Yaeger, Jeremy Brown, Claire Bortot, Tim Bean

Research Data Sets

North American Porcupines (Erethizon dorsatum) have a broad geographic distribution across much of the continent, but recent evidence suggests that their populations may be declining in some areas, including the Pacific Northwest. Estimating baseline historical and contemporary distributions of Porcupines is necessary for initiating monitoring efforts and, if necessary, informing strategic conservation actions. We compiled 1905 occurrence records of Porcupines in Washington, Oregon, and northern California from 1908 to 2018. Using maximum entropy modeling (Maxent), we created historical and contemporary distribution models based on Porcupine records from 1981–2010 and 2012–2018, respectively, to match the temporal scale of available …

Data Repository For "Use Of Redwood Basal Hollows By Bats: A Focus On The Townsend’S Big-Eared Bat On The North Coast Of California", Amon J. Armstrong

Research Data Sets

Loss of roosting resources, either through disturbance or removal, negatively affects bats. Identifying sensitive species and determining roost requirements are critical components in conserving their habitat. Cavity roosting bats on the North Coast of California are known to use hollows in large redwood trees. In this study, we examined the factors determining the use of basal tree hollows by different bat species at eight redwood forest sites in Del Norte, Humboldt, and Mendocino Counties, California. Bat guano was collected from 179 basal hollow roosts from 2017 to 2018, and guano mass was used as an index of roosting activity. Nine …

Acoustic Communication In The Atlantic Mudskipper, Periopthalmus Barbarus, Seth Hoffman

Mahurin Honors College Capstone Experience/Thesis Projects

Mudskippers are intertidal fishes that can survive both in and out of the water. They are territorial and exhibit behaviors to attract mates and defend against competitors. Recently, it has been shown that vibrations are produced and transmitted through the mud during such displays in one species, Periophthalmodon septemradiatus. To see if similar vibrations are produced in other species of mudskippers, I recorded the behavioral interactions of pairs of the mudskipper Periophthalmus barbarus via digital video and acoustic signals via accelerometer. Comparative analysis of fish mass, sex, contest length, and contest outcome coupled with acoustic characteristics within dyadic pairings …

Biodiversity Of Small Mammals And Paleoenvironment Of Transbaikalia And North Mongolia In The Late Pliocene, N. V. Alexeeva, M. A. Erbajeva

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

This paper reports the results of analysis on small mammal faunas dwelling during the Late Pliocene the Transbaikal and Northern Mongolia regions. They were found to share many common species, even though some differences linked with local and regional specifics of the environment are the case. High diversity of small mammal taxa, species richness and their prominent quantity specify the localities of Udunga, Beregovaya and Tologoi in Transbaikal region and in Shamar of Northern Mongolia. The compositions of all faunas point to the existence of the savanna-like landscapes and warm semiarid climate in that period.

Hypsugo Stubbei Sp. Nov., A Novel Cryptic Bat Species Of The Genus Hypsugo (Vespertilionidae, Chiroptera, Mammalia) From Mongolia, Dietrich Dolch, Nyamsuren Batsaikhan, Annegret Stubbe, Dirk Steinhauser

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The occurrence of two members of the genus Hypsugo, namely H. alaschanicus and H. savii caucasicus, have been reported for Mongolia in the literature. Due to various taxonomic reassignments within and between genera, the number of records for the genus Hypsugo in Mongolia is quite scarce and sometimes not resolved at species or subspecies level. Despite recognition of the two above-mentioned species, recent reports based on genetic analyses describe only new and further records of H. alaschanicus. Thus, it exists a large uncertainty regarding the occurrence and distribution of H. savii caucasicus in Mongolia. Here, our efforts …

Zur Molekularen Klassifizierung Der Mongolischen Kormorane Phalacrocorax Carbo (Linnaeus, 1758), Lucie Marie Baltz, Michael Stubbe, Davaa Lchagvasuren, Lara-Sophie Dey

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The cormorant Phalacrocorax carbo (Linnaeus, 1758) is a common breeding species at lake areas of Mongolia. Although molecular research has been conducted on many colonies worldwide, no studies of the genetic diversity of Mongolian colonies are known to date. In this study, we sequence for the first time a fragment of cytochrome oxidase 1 (CO1) from ten individuals of the 2017 resident population at Telmen-nuur. Here we perform molecular identification and analyze it in the context of existing data from populations studied worldwide. A clear assignment to the species P. carbo could be shown, but no identification on subspecies level …

Phylogenie, Morphologie Und Ökologie Mongolischer Langohrfledermäuse Der Gattung Plecotus (Mammalia, Chiroptera, Vespertilionidae), Dietrich Dolch, Bernd Gärtner, Klaus Thiele, Dirk Steinhauser, Ariunbold Jargalsaikhan, Annegret Stubbe, Nyamsuren Batsajchan, Davaa Lchagvasuren

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The Palaearctic is a zoogeographical region where knowledge of the distribution, taxonomy and ecology of bats (Chiroptera) is generally quite extensive. However, for many Palaearctic subregions, including Mongolia, detailed knowledge is still quite scarce. Also for some groups of species there are only few studies available to date. This holds also true for the long-eared bats of the genus Plecotus. For the long-eared bats, which live in close family groups and do not migrate over long distances, the development of different life form types can be expected. Studies tackling this are so far lacking.

The fundamental revision of the …
