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. …

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 …

Ramapough/Ford The Impact And Survival Of An Indigenous Community In The Shadow Of Ford Motor Company’S Toxic Legacy, Chuck Stead

Antioch University Dissertations & Theses

The purpose of this study was to examine the history of the Ford Motor Company’s impact upon the Ramapo Watershed of New York and New Jersey, as well as upon the Ramapough Munsi Nation, an indigenous population living there. In a 25 year span the automaker produced a record number of vehicles and dumped a massive amount of lead paint, leaving behind a toxic legacy that continues to plaque the area and its residents. The Ramapough people are not unlike many native nations living in the United States who have experienced industrial excess. This study examines the mindset that allows …

Geometric Morphometric Analysis Of Pan Frontal Bone Morphology, Allen J. Myhra

Department of Anthropology: Theses and Student Research

This study employs geometric morphometric methods to investigate the morphology and shape change of the frontal bone for Pan troglodytes and Pan paniscus. Unlike previous work on the topic, this research analyzed morphology and ontogenetic shape change in a single bone of the cranium, namely the frontal bone. Frontal bone shape was compared between juvenile Pan troglodytes and Pan paniscus and the ontogeny of the bone was assessed in Pan paniscus infants and juveniles. Analyses were performed on frontal bone morphology with and without the browridge in order to assess the morphology of the frontal apart from influences …

Provisioning And Its Effects On The Social Interactions Of Tibetan Macaques (Macaca Thibetana) At Mt. Huangshan, China, Brianna I. Schnepel

All Master's Theses

The dispersal patterns of food resources has a significant effect on the composition of primate groups and social interactions within those groups. Humans often alter the dispersal of food. Non-humans often use affiliative behaviors to elicit tolerance or support from other group members. I investigated whether provisioned food resources alter the social interactions and group dynamics of Macaca thibetana. All-occurrence sampling and scan sampling were used for data recorded by camera traps. Trail-cameras were placed at six locations that contain natural and human food resources and recorded 60-second videos. Social behavior and proximity of the monkeys were recorded. I …

New Observations Of The Andean Ibis (Theristicus Branickii, Threskiornithidae): Distribution, Movements, And Behavior Near Volcán Antisana, Benjamin West

Independent Study Project (ISP) Collection

The Andean Ibis (Theristicus branickii) of the highland grasslands of Ecuador, Peru, and Bolivia is listed globally as Near Threatened and Critically Endangered in Ecuador. The Ecuadorian population is estimated at 100 individuals and is restricted to the vicinities of Volcán Antisana and Volcán Cotopaxi. Knowledge of the nesting biology of the Andean Ibis in Ecuador consists of a single filming in 1989. Much of its general ecology and movements is also unknown. The purpose of this study was to find evidence of nesting ibis in Ecuador while also collecting data on behavior, population, movements and interspecific interactions. Data was …

Dialect Use Within A Socially Fluid Group Of Southern Resident Killer Whales, Orcinus Orca, Courtney Elizabeth Smith

Master's Theses

Resident killer whales, Orcinus orca, of the Northeastern Pacific form stable kinship-based matrifocal associations and communicate with group-specific repertoires of discrete calls (dialects) that reflect these associations. The gradual fission of matrilines is usually consistent with dialect variations among groups that may manifest as differences in call usage at the repertoire level or subtle structural differences of the calls themselves. Therefore, matrilines that are more closely related tend to be more acoustically similar. Within the endangered community of Southern Resident killer whales (SRKWs), recent evidence shows that one particular group (L pod) exhibits the lowest rate of intrapod association …

Managing Devil Facial Tumour Disease In Tasmanian Devils (Sarcophilus Harrisii): An Investigation Of Heat Shock Proteins As Potential Vaccine Adjuvants, Monika Payerhin

Independent Study Project (ISP) Collection

The world’s largest carnivorous marsupial, the Tasmanian devil (Sarcophilus harrisii), is facing extinction from a deadly, highly communicable cancer that has already decimated over 85% of devil populations in the wild: devil facial tumour disease (DFTD). DFTD cells effectively evade recognition by the immune system, and every devil that contracts the disease dies from it. Many attempts have been made at developing a vaccine that could help save this now-threatened species. Heat shock proteins have been linked to enhanced immune recognition of pathogens, making them potential candidates for acting as adjuvants to such a vaccine against DFTD. In this study, …

New Study Of Altitude And Butterfly Diversity Evaluation Of Butterfly Diversity In La Hesperia And Influence Of Altitude On Diversity, Savannah Artusi

Independent Study Project (ISP) Collection

Due to the increasing effects of climate change, studies focusing on bioindicator species are becoming more necessary than ever. Additionally, knowledge about global biodiversity can be very useful to conservation organizations because it helps them determine what areas need to be conserved the most .Butterflies are useful as bioindicators due to their complex life cycles, importance in the food chain, and sensitivity to environmental changes. This project focused on studying the overall biodiversity of butterflies in the La Hesperia reserve. In addition, this study aimed to determine how butterfly diversity varies at different altitudes. To do this, the reserve was …

Examining Predation As A Possible Means Of Controlling Crown-Of- Thorns Starfish (Acanthaster Planci) Outbreaks On Reefs Around Lizard Island, Australia, Amanda Chan

Independent Study Project (ISP) Collection

Since the world’s coral reefs are currently threatened by a variety of different natural and anthropogenic factors, research on protecting coral reefs is pivotal to protect these diverse ecosystems. However, only Indo-Pacific reefs such as the Great Barrier Reef are dying due to a corallivorous echinoderm threat known as the Crown-of-Thorns Starfish (Acanthaster planci). A. planci is a starfish which feeds on coral tissue and can quickly reduce coral cover on a reef during an outbreak. Although scientists are still unsure as to what causes these outbreaks, one suggestion is the predator-removal theory. The predator removal-theory states that major predators …

Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht

United States National Park Service: Publications

Executive Summary

Agate Fossil Beds National Monument is a 3,057-acre park located in western Nebraska. The unit is comprised of northern mixed-grass prairie vegetation, typical of the Northern Great Plains. Weather, fire, and grazing are generally considered to be the ecological drivers of prairie ecosystems and critical for prairie health. However, grazing has essentially been absent since the 1960s. In 2014, a Department of the Interior report explicitly listed the park as a high priority for bison restoration. This report evaluates the feasibility, management options, benefits, and challenges of restoring bison to Agate Fossil Beds National Monument.

Population Of Northern Leopard Frogs (Rana Pipiens) Migrating Between The Ney Frog Pond And The Minnesota River Valley For Spring Breeding, Rebecca Madison Pollack

Journal of Undergraduate Research at Minnesota State University, Mankato

The Northern Leopard Frogs (Rana pipiens) found at the Ney Nature Center (NNC) are particularly important to the NNC, as they are the initial population of frogs found deformed in 1995. As bio-indicators, frog populations can be used to assess the health of their surrounding environment. This study used standard herpetological field methods to gain a population estimate of Northern Leopard Frogs and the migration route used by these frogs as they moved up the bluffs of the Minnesota River Valley from their wintering site to the Ney Frog Pond for spring breeding. The results gathered provide the Ney Environmental …

Effects Of Animal Management Changes On The Activity Budgets And Walking Rates Of Zoo Elephants, Angela Dawn Mackey

Dissertations

The current study aimed to assess the effects of two management strategies, weekly rototilling of the enclosure and the provision of unpredictable foraging opportunities, on the daily behavior of six elephants housed at the San Diego Zoo. Observations took place from January to June 2013 and were conducted throughout a 24- hour period. The study was divided into three phases, each two months in duration. During the first phase (baseline) no changes were made to the current management routine of the elephants. In Phase 2, rototilling of the elephant enclosures was increased from once monthly to once per week, while …

Evaluation Of The Functional Capabilities Of Fins And Limbs For Moving On Land: Insights Into The Invasion Of Land By Tetrapods, Sandy Kawano

All Dissertations

Transitions to novel habitats present different adaptive challenges, producing captivating examples of how functional innovations of the musculoskeletal system influence phenotypic divergence and adaptive radiations. One intriguing example is the transition from aquatic fishes to tetrapods. Recent technological advances and discoveries of critical fossils have catapulted our understanding on how fishes gave rise to terrestrial vertebrates. Considerable attention has been paid to legged locomotion on land, but given that the first tetrapods were aquatic, limbs did not evolve primarily for terrestriality. How, then, is the locomotor function of limbs different from fins? Extant amphibious fishes demonstrate that fins can be …

Habitat Effects On Chick-A-Dee Call Complexity, Jacqueline Renee Lynch

Open Access Theses

Past studies on the communication systems of species in urban environments (such as Common Starlings (Sturnus vulgaris), nightingales (Luscinia megarhynchos Brehm), brown-headed cowbirds ( Molothrus ater), Southern brown tree frogs (Litoria ewingii )) have shown multiple ways that species change vocal signaling behavior to adjust to urban habitats (e.g. alarm calls and singing). This study further investigates the changes in signaling in relation to the chick-a-dee call of the Carolina chickadee (Poecile carolinensis). A secondary goal of this study was to compare both the amount of information and rate of calling across …

Behaviors That Predict Personality Components In Adult Free-Ranging Tibetan Macaques (Macaca Thibetana), Alexander J. Pritchard, Lori K. Sheeran, Kara I. Gabriel, Jin-Hua Li, Ronald S. Wagner

Anthropology and Museum Studies Faculty Scholarship

To further the potential for applied personality studies, we present a methodology for assessing personality in nonhuman animals without a priori assumptions, using behavioral measures to discriminate personality survey results. Our study group consisted of 12 free-ranging, provisioned, adult Tibetan macaques (Macaca thibetana) at the Valley of the Wild Monkeys, China. We asked familiar Chinese park guards and scientists to rate each of the 12 macaques using 27-item personality surveys. We also recorded behavioral observations (> 100 hrs) from August–September, 2012. The personality surveys showed reliability in 22 of the items that were then utilized in a principal component analysis …

Feedforward And Feedback Projections Of Caudal Belt And Parabelt Areas Of Auditory Cortex: Refining The Hierarchical Model, Troy A. Hackett, Lisa A. De La Mothe, Corrie R. Camalier, Arnaud Falchier, Peter Lakatos, Yoshinao Kajikawa, Charles E. Schroeder

Psychological Sciences and Counseling Faculty Research

Our working model of the primate auditory cortex recognizes three major regions (core, belt, parabelt), subdivided into thirteen areas. The connections between areas are topographically ordered in a manner consistent with information flow along two major anatomical axes: core-belt-parabelt and caudal-rostral. Remarkably, most of the connections supporting this model were revealed using retrograde tracing techniques. Little is known about laminar circuitry, as anterograde tracing of axon terminations has rarely been used. The purpose of the present study was to examine the laminar projections of three areas of auditory cortex, pursuant to analysis of all areas. The selected areas were: middle …

Averting Lemur Extinctions Amid Madagascar's Political Crisis, Christoph Schwitzer, Russell Mittermeier, Steig Johnson, Giuseppe Donati, Mitchell Irwin, Heather Peacock, Jonah Ratsimbazafy, Josia Razafindramanana, Edward E. Louis, Lounes Chikhi, Ian C. Colquhoun, Jennifer Tinsman, Ranier Dolch, Marni Lafleur, Stephen Nash, Erik Patel, Blanchard Randrianambinina, Tove Rasolofoharivelo, Patricia C. Wright

Anthropology Publications

The most threatened mammal group on Earth, Madagascar’s five endemic lemur families (lemurs are found nowhere else), represent more than 20% of the world’s primate species and 30% of family-level diversity. This combination of diversity and uniqueness is unmatched by any other country—remarkable considering that Madagascar is only 1.3 to 2.9% the size of the Neotropics, Africa, or Asia, the other three landmasses where nonhuman primates occur. But lemurs face extinction risks driven by human disturbance of forest habitats. We discuss these challenges and reasons for hope in light of site-specific, local actions proposed in an emergency conservation action plan.

Differential Responding By Rhesus Monkeys (Macaca Mulatta) And Humans (Homo Sapiens) To Variable Outcomes In The Assurance Game, Audrey E. Parrish, Sarah F. Brosnan, Bart J. Wilson, Michael J. Beran

Economics Faculty Articles and Research

Behavioral flexibility in how one responds to variable partner play can be examined using economic coordination games in which subjects play against a variety of partners and therefore may need to alter their behavior to produce the highest payoff. But how do we study this behavioral flexibility once players have settled on a response? Here, we investigated how responding by rhesus monkeys (Macaca mulatta) and humans (Homo sapiens) playing a computerized single-player version of a coordination game, the Assurance game, changed as a function of the variable responses (Stag/Hare) generated by multiple simulations (SIMs). We were interested in whether individuals …

Animals' Capability To Bond And The Implications That Follow, Falyn Goldfarb

Honors College Theses

This paper explores the ways in which humans have historically viewed animals, with a focus on Descartes theory automata. Further concepts of the problem of different minds, inherent value, empathy, love, friendship, grief, isolation, anthropomorphism, and biochemistry (focusing on oxytocin, cortisol and the prefrontal cortex) are all explored. Numerous literature reviews are used as examples to fight against the argument that animals are merely machines and can therefore be used and abused. Animal social bonds, including parent-child, purely social, and animal-human, are analyzed for their evolutionary and biological purposes in attempt to highlight the relationships that are not obviously valuable …
