Investigations Into The Incidence And Control Of Selected Parasites And Pathogens Which Infect Arkansas Horses, Stephanie Ann O'Berg Rainbolt

Graduate Theses and Dissertations

Parasite control is an important aspect of health management of horses, particularly the control of gastrointestinal (GI) parasites. Recently, treatment recommendations have involved selective use of anthelmintics in horses with fecal egg counts (FEC) greater than a specified threshold. The objectives of this study were; (1) to determine the prevalence of helminths in our area by egg and L3 determinations, (2) to determine if certain horses maintained low FEC, therefore eliminating the need to treat them on a year-round basis and (3) to determine the effectiveness of four common treatments (moxidectin, ivermectin (pioneer and generic), fenbendazole and pyrantel tartrate) via …

Comparison Of Microwear On Rodent Molars From Differing Species And A Wide Range Of Environments, Mikko Joiner

Anthropology Undergraduate Honors Theses

Dental microwear analysis is a very useful tool when trying to infer the diet of a particular organism. By studying the use-wear scars left on the enamel of the tooth due to eaten objects, one can infer the diet of the organism because certain types of food leave certain types of scars. For example, the consumption of tree parts produces pits, while the consumption of grasses produces striated scratches (Ungar et al., 2007). Thus, based on the type of microwear, the diet of the organism in question can be deduced, which indicates the type of environment that it lives in. …

Two New Euscorpius Species From Central-Western Greece (Scorpiones: Euscorpiidae), Gioele Tropea, Victor Fet

Euscorpius

Two new Euscorpius species are described, based on specimens collected by P.M. Giachino & D. Vailati in central-western Greece in neighboring Aitoloakarnania (Western Greece) and Fokida (Central Greece) regional units. No Euscorpius specimens were previously available from this area. The first new species, Euscorpius giachinoi sp. n., is very similar to a recently described E. birulai Fet et al., 2014 from Euboea Island, and is also characterized by a low trichobothrial count (Pv = 7, et = 5), a low pectinal teeth count (Dp = 7 in males, 6 in females), and long-limbed features. The second species, …

Manipulation Of Same Sex Social Pair Bonds In Budgerigars, Melopsittacus Undulatus, Amanda M. Stilwell

Undergraduate Distinction Papers

Same sex pair bonding can be found throughout various animal species. These relationships can be common in monogamous species, especially when there is a lack of members of the opposite sex. Budgerigars, Melopsittacus undulatus, are a socially monogamous species, which create strong pair bonds but are also known to engage in extra pair copulations. When looking at an all-male flock of budgerigars, the question arises, are these bonds easily broken or disrupted by a third party individual. After determining seven pair bonds in a flock of 32 males, these pairs were removed from an aviary and placed in separate …

Isotopic Incorporation Rates And Discrimination Factors In Mantis Shrimp Crustaceans., Maya Devries, Carlos Del Rio, Tate Tunstall, Todd Dawson

Faculty Publications, Biological Sciences

Stable isotope analysis has provided insights into the trophic ecology of a wide diversity of animals. Knowledge about isotopic incorporation rates and isotopic discrimination between the consumer and its diet for different tissue types is essential for interpreting stable isotope data, but these parameters remain understudied in many animal taxa and particularly in aquatic invertebrates. We performed a 292-day diet shift experiment on 92 individuals of the predatory mantis shrimp, Neogonodactylus bredini, to quantify carbon and nitrogen incorporation rates and isotope discrimination factors in muscle and hemolymph tissues. Average isotopic discrimination factors between mantis shrimp muscle and the new diet …

A Behavioral Analysis Of The Pre-Release Tasmanian Devils (Sarcophilus Harrisii) Currently At Devils@Cradle: An Assessment Of The Impacts Of Captivity On The Wild Behaviors Of Tasmanian Devils That Are Important For Their Reintroduction, Survival, And Inclusion In Wild Populations, Anna Staudenmaier

Independent Study Project (ISP) Collection

The Tasmanian devil, Sarcophilus harrisi, is in danger of extinction in the wild due to the emergence of Devil Facial Tumor Disease (DFTD). In an attempt to save the species the Save the Tasmanian Devil Program (STTDP) has initiated the creation of an ‘Insurance Population’. These insurance animals are a part of the captive breeding population (CBP) designed to conserve the genetic diversity of the species to preserve their ecological function for their future reintroduction into the wild. CBPs are located at various bio-secure zoos, wildlife parks, free-range enclosures (FREs), Tasmanian islands and peninsulas and sanctuaries like Devils@Cradle - Tasmanian …

Fauna Census Of Intertidal Cliffs, Mangapwani, Zanzibar, Emily Jankowski

Independent Study Project (ISP) Collection

Due to their extreme variations in condition over the course of a day, intertidal zones are challenging environments. Organisms that live there must be prepared to cope with both exposure and submersion, not to mention the temperature variations that accompany these conditions. The differing tolerances and adaptations of various organisms to these conditions generally cause patterns of vertical zonation to occur in the intertidal zone, especially when the shore is steep and rocky. Understanding the ecology of shore environments is important to future conservation and management efforts. This study was conducted on a beach in Mangapwani, Zanzibar at at 6˚ …

Tracking The Elephant (Lexodonta Africana) Corridor And The Human-Wildlife Conflict In Selela Village, Nicole Chlebek, Laura Stalter

Independent Study Project (ISP) Collection

The beastly journey of long-distance migration for the African Elephant (Lexodonta Africana) is important for upholding their connections between diminishing protected areas, especially in northeastern Tanzania. However, human development is encroaching into these corridors, creating a human-elephant conflict, which can ruin livelihoods of villagers, depending on the extent of conflict. This study focused on exploring the hypothesized human-elephant conflict on the Selela corridor, specifically in Selela village, as well as GPS (Global Positioning System) mapping evidence of elephant travel along the projected Selela elephant corridor connecting Ngorongoro Conservation Area (NCA), to Selela Forest Reserve (SFR), and finally to Manyara Ranch. …

The Behavioral Causes Of Reproductive Skew In Cooperatively Polygynandrous Acorn Woodpeckers (Melanerpes Formicivorus), Anna C. Brownson

Biological Sciences Theses & Dissertations

Reproductive skew, the degree to which reproduction is shared among same-sex individuals in a social group, is a pattern affected by ecological conditions, sociality, cooperation, and the inter- and intrasexual behavior of individuals in complex animal societies. Transactional and compromise skew models assume that high skew is the product of dominance hierarchies among cobreeders, yet this has rarely been tested. Both model types fail to incorporate the decisions of more than two individuals, generally overlooking the effect of female behavior on male reproductive success in multi-male groups, and are ineffective at predicting skew in larger groups characterized by more than …

A Comparison Of The Genetic Diversity Of The Class Ii Major Histocompatibility Complex In Ex Situ And In Situ Populations Of African Penguins (Spheniscus Demersus), Emily Willmer

Undergraduate Honors Thesis Projects

As an endangered species, the African penguin (Spheniscus demersus) is at risk of becoming extinct in the wild due to destruction of their coastal habitat and reduction in food availability. The development of a genetically diverse and healthy captive population is important in helping to conserve the species. The goal of this project was to determine the genetic diversity of the class II major histocompatibility complex (MHC) of a wild population of African penguins and compare it to the diversity of the captive population at Mystic Aquarium in Mystic, Connecticut that has previously been studied. We found that …

Historical And Contemporary Demography Of Leaf-Toed Geckos (Phyllodactylidae: Phyllodactylus) In The Mexican Dry Forest, Christopher Blair, Victor H. Jiménez Arcos, Fausto R. Méndez De La Cruz, Robert W. Murphy

Publications and Research

Disentangling the relative influence of historical versus contemporary processes shaping the spatial distribution of genetic variation is critical if we are to effectively mitigate key biodiversity issues. We utilize a comprehensive approach based on different molecular marker types and analytical methods to understand the demographic consequences of recent habitat fragmentation in a spatially explicit context. We focus our efforts on native leaf-toed geckos (Phyllodactylus tuberculosus saxatilis) throughout fragmented habitat in the tropical dry forest of northern Mexico as recent evidence suggests that geographic ranges for these geckos may be much smaller than currently realized. However, no data are …

Habitat Selection, Behavior, And Natural History Of The Newly Described Leaf Chameleon Brookesia Micra (Reptilia, Squamata, Chamaeleontidae; Glaw, Köhler, Townsend & Vences, 2012) On Nosy Hara, Madagascar, Andrew Villeneuve

Independent Study Project (ISP) Collection

The micro leaf chameleon genus Brookesia is exclusively endemic to Madagascar and represents some of the smallest reptiles in the world. The newly-described species Brookesia micra is exclusively endemic to the islet Nosy Hara in the north of Madagascar, and is the smallest described Brookesia species member. There exists no density, behavioral, or habitat preference studies on B. micra. Here, the researcher presents preliminary density, behavioral, habitat selection, and natural history information on B. micra. A total of 117 B. micra had data collected on them between April 10 and April 23, 2015. Density was found to be 1950 B. …

Fish Use Of Largely Unexplored Sub-Tidal Habitats In The Hinchinbrook Channel Estuary, Queensland, Alexandra Parisien

Independent Study Project (ISP) Collection

This study examines the use of sub-tidal open-bottom, rocky, and seagreass habitats by the Siganus genus (herbivores), Gerres genus (benthivores), and planktivores in the Hinchinbrook Channel Estuary in Queensland, Australia. The Hinchinbrook Channel Estuary, a tropical estuary cutting between Hinchinbrook Island and the Australian mainland, is surrounded primarily by mangroves. Its sub-tidal habitats are largely unexplored due to factors such as low visibility and the presence of estuarine crocodiles. In this study, I reviewed 699 underwater videos collected by James Cook University PhD candidate Michael Bradley in order to analyze feeding and movement behavior of pre-identified fish.

The results of …

Tallgrass Prairie Vegetation Response To Spring Fires And Bison Grazing, Stephen L. Winter, Brady W. Allred, Karen R. Hickman, Samuel D. Fuhlendorf

School of Natural Resources: Faculty Publications

Spring fires in tallgrass prairie can create environmental conditions conducive to plant growth in the subsequent growing season. Following fires, burned areas can also be attractive to grazing animals such as bison (Bison bison). Sustained grazing activity within recently burned areas can alter vegetation structure relative to nearby landscape patches that haven’t burned recently. In 2007, we collected data on bison grazing activity, vegetation structure, and the growth and reproduction of a perennial forb, Arnoglossum plantagineum, in Oklahoma tallgrass prairie. We compared these variables in landscape patches that had burned in the spring of 2007 to measurements …

2014–2015 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Fourteen counts were held during the 2014–15 Christmas Bird Count season, which is one less than last season. Although the Beaver Valley and Harrison counts were not done this season, the Harlan County count was resumed after a twelve-year hiatus and produced several noteworthy species counts. It also should be noted that the Grand Island count was held on December 13, which is one day before the official Audubon sanctioned count period begins, but its results are included in this discussion.

Following a very mild first week of November, the second week started with a sudden cold snap which persisted …

Winter Field Report, December 2014 To February 2015, W. Ross Silcock

Nebraska Bird Review

As with last winter, this was a rather ordinary winter ornithologically speaking, if indeed there is such a thing. There were a couple of genuine rarities to spice it up, but most of the interest was in unusual phenomena shown by a range of species. Ducks and swans and native sparrows seem to be more in evidence in mid-winter than in previous years, but it is difficult to relate winter occurrence to weather in any given year, except for isolated extreme events. There are, however, some trends showing up, as suggested by the ducks, swans, native sparrows, and a few …

A Hybrid Cliff × Barn Swallow From Western Nebraska, Charles R. Brown, Catherine E. Page

Nebraska Bird Review

The Cliff Swallow (Petrochelidon pyrrhonota) and the Barn Swallow (Hirundo rustica) occupy sympatric breeding ranges across much of North America, often nesting at colony sites that contain both species. Mixed-species nesting aggregations typically occur in box-shaped concrete culverts underneath roads or railways. Cliff Swallows’ enclosed mud nests can be as close as 1 m to Barn Swallows’ open mud nests, and at such sites Cliff Swallows regularly usurp both inactive and active Barn Swallow nests. The close proximity of these two ecologically similar species leads to at least occasional social interaction among them, such as during …

Observational Learning In The Jumping Spider Phidippus Audax, Robert M. Adams

School of Biological Sciences: Dissertations, Theses, and Student Research

Observational learning is a complex form of learning most frequently studied in social vertebrates. However, evidence for social learning exists in several invertebrate species Evidence of invertebrate observational learning also exists, though to a lesser extent. This study addresses observational learning in a jumping spider (Phidippus audax) through video playback. My results suggest that while observational learning is occurring, the exact mechanism in use remains unclear. Spiders that saw a conspecific satiate itself on a prey item readily attacked a similar prey item when exposed to a live prey item. However, spiders exposed to a conspecific rejecting or …

Recurrent Evolution Of Melanism In South American Felids, Alexsandra Schneider, Corneliu Henegar, Kenneth Day, Devin Absher, Constanza Napolitano, Leandro Silveira, Victor A. David, Stephen J. O'Brien, Marilyn Menotti-Raymond, Gregory S. Barsh, Eduardo Eizirik

Biology Faculty Articles

Morphological variation in natural populations is a genomic test bed for studying the interface between molecular evolution and population genetics, but some of the most interesting questions involve non-model organisms that lack well annotated reference genomes. Many felid species exhibit polymorphism for melanism but the relative roles played by genetic drift, natural selection, and interspecies hybridization remain uncertain. We identify mutations of Agouti signaling protein (ASIP) or the Melanocortin 1 receptor (MC1R) as independent causes of melanism in three closely related South American species: the pampas cat (Leopardus colocolo), the kodkod (Leopardus guigna), and Geoffroy’s cat …

Evolution Of Bat-Trypanosome Associations And The Origins Of Chagas Disease, Christian Miguel Pinto

Dissertations, Theses, and Capstone Projects

Trypanosoma cruzi is a genetically diverse parasite that causes Chagas disease, one of the most important zoonoses in the Americas. This generalist parasite of mammals belongs to a clade mostly comprised of bat parasites, the T. cruzi clade. The origins (i.e., biogeographic history and evolution of hosts associations) of this parasite are far from being understood, and the main areas that need further study are: species limits within T. cruzi sensu lato, further studies on the diversity of T. cruzi clade members and their hosts, and research on adaptations of the hosts to trypanosome infections. In this dissertation I explore …
