The Effects Of White-Nose Syndrome On Cave-Dwelling Bats During Their Pre-Hibernation Season In Eastern Nebraska, 2020 University of Nebraska at Omaha
The Effects Of White-Nose Syndrome On Cave-Dwelling Bats During Their Pre-Hibernation Season In Eastern Nebraska, Maggie Bockart
White-nose syndrome (WNS) is currently the leading cause of death to North American bats and was first documented in the United States in 2006 on the East Coast. Infection with the fungus Pseudogymnoascus destructans (Pd) causes bats to arise from hibernation with unnecessary frequency, leading to depletion of fat reserves that are imperative for extended periods of torpor. In October 2014, biologists surveyed the activity levels of bats at Fontenelle Forest in eastern Nebraska using acoustic detectors and determined what species of bats were present and their relative abundance before being exposed to WNS. By returning to the same region ...

Evaluation Of Selected Bacillus Direct-Fed Microbial Candidates In Reduced Energy Diets On Live Performance, Carcass Characteristics, And Foot Pad Dermatitis, 2020 University of Arkansas, Fayetteville
Evaluation Of Selected Bacillus Direct-Fed Microbial Candidates In Reduced Energy Diets On Live Performance, Carcass Characteristics, And Foot Pad Dermatitis, Kyle Teague
Graduate Theses and Dissertations
Bacillus spp. are ubiquitous, Gram-positive, spore forming bacteria that are commonly recovered from the environment and gastrointestinal tract (GIT) of poultry. These spores are capable of withstanding harsh condition such as feed pelletization, which facilitates inclusion in poultry feeds. Once ingested by the bird, spores germinate into metabolically active vegetative cells which can produce extracellular enzymes which can hydrolyze otherwise indigestible components of the feed. Soybean meal (SBM) is the gold standard vegetable protein source for non-ruminant animals worldwide and is included in practically all poultry diets in the United States at levels ranging from 10 to more than 30 ...
Sexually Dimorphic Oxytocin Receptor-Expressing Neurons In The Anteroventral Periventricular Nucleus Regulates Maternal Behavior, 2020 Louisiana State University and Agricultural and Mechanical College
Sexually Dimorphic Oxytocin Receptor-Expressing Neurons In The Anteroventral Periventricular Nucleus Regulates Maternal Behavior, Kaustubh Sharma
LSU Doctoral Dissertations
The neurohypophysial hormone oxytocin is involved in the regulation of social behaviors, including social recognition, pair bonding, and sex-specific parental behaviors in a variety of species. Oxytocin triggers these social behaviors by binding to oxytocin receptors (OXTR) in various parts of the brain. Oxytocin-induced sex-typical behavior, therefore, suggests a sexual dimorphic distribution of OXTR in the brain. In recent years, the oxytocin system in the brain received tremendous attention as a potential pharmacological target for treatment of many psychiatric disorders, such as anxiety, autism spectrum disorders, and even sex-specific psychiatric disorder like postpartum depression (PPD). An important problem and a ...

In the United States alone, there are >5,000 state-licensed wildlife rehabilitators in addition to a multitude of other wildlife caregivers across rehabilitation and sanctuary settings. Wildlife rehabilitation and sanctuary care provide a unique lens from which to explore human–wildlife interactions. We examined the experiences of wildlife caregivers within a continuum of acute veterinary services, community-based rehabilitation, and sanctuary care to gain insight into wildlife caregiving and its implications for human–wildlife coexistence. Between 2016 and 2018, we completed in-depth interviews with 15 wildlife caretakers in Massachusetts, Maine, and New Hampshire, USA. In addition to the interviews, we observed ...
Role Of Farmer Knowledge In Agroecosystem Science: Rice Farming And Amphibians In The Philippines, 2020 Northern Arizona University
Role Of Farmer Knowledge In Agroecosystem Science: Rice Farming And Amphibians In The Philippines, Catherine R. Propper, Lisa J. Hardy, Brittni D. Howard, Rica Joy B. Flor, Grant R. Singleton
Rice (Oryza sativa) agriculture provides food and economic security for nearly half of the world’s population. Rice agriculture is intensive in both land and agrochemical use. However, rice fields also provide aquatic resources for wildlife, including amphibians. In turn, some species may provide ecosystem services back to the farmers working in the rice agroecosystem. The foundation for understanding the complexity of agroecosystem–human relationships requires garnering information regarding human perceptions and knowledge of the role of biodiversity in these rice agroecosystems. Understanding farmer knowledge and perceptions of the ecosystem services provided by wildlife in their fields, along with their ...

Do Actions Speak Louder Than Words? Communicative Frequencies And Multimodality In Ring-Tailed Lemurs (Lemur Catta), Hilary Hager
Electronic Thesis and Dissertation Repository
The study of multimodal communication in primatology has increased only recently. At present, there are no on-going investigations of multimodal communication in ring-tailed lemurs (Lemur catta), despite the body of research on this species. I investigated how different modes of L. catta inter-individual multimodal communication are socially coordinated and integrated by examining frequencies of occurrence within four potential biological and social factors: age, troop affiliation, sex, and dominance rank. Research was conducted over four months at the Duke Lemur Center, Durham, NC, on 14 individuals from three separate troops of captive, free-ranging L. catta. Results demonstrate communicative variation in unimodal ...

We Studied What Happens When Guys Add Their Cats To Their Dating App Profiles, Lori Kogan, Shelly Volsche
Anthropology Faculty Publications and Presentations
If you’ve used a dating app, you’ll know the importance of choosing good profile pics.
These photos don’t just relay attractiveness; a recent study suggested that 43% of people think they can get a sense of someone’s personality by their picture. You might guess that someone who has included a photo of themselves hiking is an outdoorsy type of person.
But as scientists who study human-animal interactions, we wanted to know what this meant for pet owners – in particular, male cat owners.
If you’re a guy who owns a cat, what kind of effect does ...
Something To Celebrate?: Demoting Dairy In Canada's National Food Guide, 2020 University of Victoria
Something To Celebrate?: Demoting Dairy In Canada's National Food Guide, Maneesha Deckha
Journal of Food Law & Policy
In early 2019, the Canadian Government released the much-anticipated new Canada Food Guide. It is a food guide that de-emphasizes dairy products and promotes plant-based eating. Notably, in the new version, milk and milk products are de-listed as one of the previously four essential food groups. On the surface, it seems that the federal government is promoting veganism and helping to bring about a friendlier future for animals and humans harmed by being producers and consumers of dairy, as the new Guide may seriously contract the currently robust Canadian dairy industry and its powerful lobby. On closer inspection, the messaging ...
The Effects Of Adolescent Chronic Mild Stress: In Female Wistar-Kyoto Rats, 2020 Purdue University
The Effects Of Adolescent Chronic Mild Stress: In Female Wistar-Kyoto Rats, Anna Hallowell
The Journal of Purdue Undergraduate Research
Despite years of research to understand under-lying mechanisms and develop more effective treatment approaches for mood disorders, numerous challenges exist. Many chronic stress models are used to study mood disorders, how-ever the majority have been established with adult males. This is problematic considering that affective disorders are more common in women, and generally develop during late adolescence. Studies have indicated fundamental behavioral, physiological, and neural differences between males and females in response to the same external stressors, furthering a need to develop sex-specific paradigms to accurately model the etiology of mood disorders in females. The Wistar-Kyoto (WKY) rat strain is ...

The Olfactory And Auditory Capabilities Of Dogs (Canis Lupus Familiaris) For Locating Different Quantities Of Food, Shayla Jackson
Electronic Thesis and Dissertation Repository
Although some animals, such as elephants, can use olfaction to discriminate quantities of food, previous research suggested dogs cannot smell the difference between quantities of hot dog slices. In the experiments reported here, dogs were allowed to smell two opaque containers under which were placed different numbers of hot dog slices, and then were allowed to make a choice between containers. In Experiment 1, dogs chose between one and five hot dog slices and chose the larger quantity at an above chance level. In Experiment 2 and Experiment 3, I tested whether dogs conformed to the distance effect and/or ...

The beneficiaries of the program were selected based on specific criteria and qualifications. Farmers were given training on dairy cattle production, and 10 beneficiaries in five communities received one ready-to-breed cow. Each farmer-beneficiary established a 500 sqm pasture area using FLSST. Abundant grasses and leguminous forages helped improve the health of the cattle. Cattle weighing an average of 150 kg grew to an average weight of ...
Human Supremacy As Posthuman Risk, 2020 New Jersey Institute of Technology
Human Supremacy As Posthuman Risk, Daniel Estrada
The Journal of Sociotechnical Critique
Human supremacy is the widely held view that human interests ought to be privileged over other interests as a matter of ethics and public policy. Posthumanism is the historical situation characterized by a critical reevaluation of anthropocentrist theory and practice. This paper draws on animal studies, critical posthumanism, and the critique of ideal theory in Charles Mills and Serene Khader to address the appeal to human supremacist rhetoric in AI ethics and policy discussions, particularly in the work of Joanna Bryson. This analysis identifies a specific risk posed by human supremacist policy in a posthuman context, namely the classification of ...
