Incidental Captures Of Plains Spotted Skunks (Spilogale Putorius Interrupta) By Arkansas Trappers, 2012-2017, D. Blake Sasse
Journal of the Arkansas Academy of Science
Arkansas trappers were surveyed following the 2012 and four subsequent trapping seasons regarding accidental captures of spotted skunks while attempting to trap other species. A total of 132 trappers reported capturing spotted skunks although further investigation confirmed the validity of only 42 reports from trappers that caught a total of 60 spotted skunks. Incidental captures were rare; only 0.35-1.29% of trappers each year caught spotted skunks and came primarily from the Ozark and Ouachita regions of the state.

Re-Evaluating Captive Chimpanzee “Dominance”: Dominance Hierarchy And Chimpanzee-Caregiver Relationships At Chimpanzee Sanctuary Northwest, Jake Funkhouser
All Master's Theses
This thesis is composed of two journal-ready articles and an accompanying appendix with additional data and interpretation. Overall, this thesis describes and statistically analyzes dominance relationships in two nonhuman primate groups with novel methods, possible correlations between dominance and testosterone, and uncovers the prominent connection of caregivers to captive chimpanzee social networks. Chapter I addresses current and past variability in behavioral measures and statistical methods to derive dominance rankings. I propose a novel approach to using existing statistical techniques to analyze dominance ranks, context-dependent dominant structures (agonistic competitions, lack of agonism, privileged role, priority access to resources), the reliability of …

Response Of Three Species Of Monkeys To Caregiver Use Of Species-Typical Behavior, Lillian Anna Stolar
All Master's Theses
Caregivers are a primary part of captive monkey environments. When addressing psychological well-being of captive nonhuman primates, social environment should be considered. Chimpanzees, gorillas, New World monkeys, and Old World monkeys responded positively to interactions with caregivers. Some species showed increased affiliative behaviors and decreased abnormal or self-directed behaviors after interactions. These studies showed that caregivers can affect the behavior of nonhuman primates. Caregivers are underutilized as a source of social interaction for captive nonhuman primates. Utilizing species-typical behaviors during interactions, caregivers and nonhuman primates can communicate and interact in different ways that may be beneficial to both caregiver and …

Life In The Dirt: Factors Influencing The Behavior And Distribution Of Spea Intermontana In Eastern Washington State, Corey Brumbaugh
All Master's Theses
I divided my thesis into two major studies focusing on the Great Basin Spadefoot Toad, Spea intermontana, at the Beverley Dunes (Beverley, WA). The first study explored the effects of temperature and water level on the rate of metamorphosis. We gathered data on rates of development, survival, body mass, snout-vent length, and hind leg length of metamorphs under 4 treatments: 20C x High Water, 30C x High Water, 20C x Water Loss, and 30C x Water Loss. These data show that temperature has a stronger effect on the overall rate of metamorphosis of Great Basin Spadefoot Toads. The second …

Single And Pair Housed Chacma Baboons’ (Papio Ursinus) Response To Caregivers’ Use Of Species-Specific Behavior, Josefine Holm
All Master's Theses
Most captive primates suffer from stereotypical or abnormal behavior which can be reduced by implementing enrichment protocols. There is, however, often spatial or economic limitations to facilities’ enrichment programs, and implementing the most beneficial and cost-effective enrichment is therefore crucial to ensure the best welfare for captive primates. Social enrichment has been designated as the most effective type of enrichment, but often captive primates cannot be housed in social groups. Through this study, I wanted to determine if species-specific behavioral interactions between human caregivers and captive chacma baboons (Papio ursinus)would alter the baboons’ behaviors, and if these interactions could …

Evaluating Current And Future Range Limits Of An Endangered, Keystone Rodent (Dipodomys Ingens), Ivy V. Widick
Cal Poly Humboldt theses and projects
Climate is often considered the single most important factor limiting species’ ranges. Other factors, such as biotic interactions, are often assumed to be included via abiotic proxies. However, differential responses to climate change may decouple these relationships or lead to adaptation to novel environments. Accounting for competition and local adaptation should more accurately describe environmental factors influencing current distributions and increase the predictive accuracy of future distributions. Modeling the endangered giant kangaroo rat (Dipodomys ingens) is an excellent application of these model improvements, as the species range consists of geographically and genetically isolated populations experiencing disparate climatic change. …

Comparative Diet Of Hedgehogs (Atelerix Algirus) In Two Localities In Kabylia, Algeria, Dalila Djennoune, Faiza Marniche, Mansour Amroun, Raphaël Boulay
Turkish Journal of Zoology
The present study is the first qualitative and quantitative analysis of the diet of Algerian hedgehogs (Atelerix algirus) in Kabylia, Algeria. The study was carried out between May and October 2014 and covered two different sites, Yakouren (a forested site) and Tizi-Rached (an agricultural site). In Yakouren, the analysis of droppings allowed us to identify 12,050 items grouped into 16 categories of eaten preys, while in Tizi-Rached, 13,543 items grouped into 13 categories of preys were identified. In both locations, the Hymenoptera category is the most eaten type of prey at a rate of 93% in Yakouren and 98% in …

A Chronology Of Diet And Habitat Use In The Florida Manatee (Trichechus Manatus Latirostris): Insights From Stable Isotope Analysis, Malia Smith
Williams Honors College, Honors Research Projects
The Florida Manatee (Trichechus manatus latirostris) is a threatened species that primarily feeds on marine and estuarine seagrasses. Over the past several years, the seagrass coverage in the Indian River Lagoon has varied due to human influence and algal blooms. This led to an unusual number of manatees dying and potentially, to remaining manatees shifting their diets. It can be difficult to decipher why or how diets shift, however, creating a timeline using stable isotopes can help address this challenge. Red blood cells from live Florida Manatees were analyzed for stable carbon, nitrogen, and sulfur isotope ratios. All …
The Many Faces Of Fear And Vigilance,

The Many Faces Of Fear And Vigilance, Guy Beauchamp
Animal Sentience
In the target article, I examined the relationship between vigilance and fear in prey animals. The joint occurrence of vigilance and other physiological responses to fear, such as increased heart rate and stress hormone release, would bolster the idea that vigilance can be a useful marker of fear. Nevertheless, a common theme in much of the empirical research is an uncoupling of vigilance and physiological correlates of fear. The commentators suggest several ways to refine the concepts of vigilance, fear, and risk. I discuss these refinements, which in the end will prove useful to assess further the relationship between vigilance …

Portable Electric Fencing For Bear Deterrence And Conservation, Tom S. Smith, Bryan Hopkins, John Gookin, Samantha Thompson
Human–Wildlife Interactions
Although bear-inflicted (Ursus spp.) human fatalities are rare in North America, human injuries, property damage, and bear mortalities occur wherever bears and humans commingle. We investigated the efficacy of portable electric fencing systems for bear deterrence under a variety of environmental conditions in the lab and field. Our results showed that the bear deterrent systems we evaluated were effective in protecting humans, their food, and property from bears >99% of the time. Herein, we discuss the benefits of using electric fencing, reasons why fences sometimes fail, and provide guidance regarding the most effective implementation of the systems we evaluated. …

Motivations And Satisfaction Of North Dakota Deer Hunters During A Temporal Decline In Deer Populations, Kristen E. Black, William F. Jensen, Robert Newman, Jason R. Boulanger
Human–Wildlife Interactions
Achieving state wildlife agency biological goals for deer (Odocoileus spp.) management may often conflict with hunter desires. Concomitantly, better information is needed to optimize agency deer herd management goals with hunters’ social goals. In 2016, we surveyed 3,000 North Dakota, USA, resident deer hunters using a self-administered mail survey to gain a better understanding of motivations, satisfaction, and hunter demographics that may be used to inform hunter recruitment and retention (HRR) efforts during a period of reduced statewide deer populations. With deer-gun license availability strictly limited, we explored the possibility that some gun hunters may have been engaging …

New Records Of Pelagic Fauna From The Turkish Waters, Sedat Ozan Güreşen, Onur Gönülal
Turkish Journal of Zoology
In this work, three pelagic species have been recorded in the Northern Aegean Sea. The species were collected from depths between 500 and 800 m from 5 stations in summer 2016. While Euphausia krohnii is first recorded from the Turkish coast of the Aegean Sea, Allosergestes sargassi and Flaccisagitta hexaptera are reported for the first time from the Turkish seas. The results of the current study will contribute to the knowledge on the deep-water pelagic fauna of the Northern Aegean Sea.

N Integrative Description Of A Population Of Mesobiotus Radiatus(Pilato, Binda & Catanzaro, 1991) From Kenya, Daniel Stec, Milena Roszkowska, Lukasz Kaczmarek, Lukasz Michalczyk
Turkish Journal of Zoology
In a moss sample collected from Mount Kulal in Kenya, a new population of Mesobiotus radiatus was found. Given that the original description of M. radiatus was based solely on the morphology observed by light microscopy and measurements based mostly on a single individual, here we describe the new population by means of integrative taxonomy and a large sample size. We provide an integrative description comprising a comprehensive set of morphometric and morphological data from light and scanning microscopy as well as nucleotide sequences of three nuclear fragments (18S rRNA, 28S rRNA, ITS-2) and one mitochondrial fragment (COI). Mesobiotus radiatus …

Changes Of Hypothalamic-Pituitary-Testicular Axis In Male Rats During Cognitive Impairment, Patteera Wititsuwankul
Chulalongkorn University Theses and Dissertations (Chula ETD)
From the previous reports denoting that hypothalamus regulating reproductive function via hypothalamic-pituitary-testicular (HPT) axis, and hippocampus controlling learning and memory capacity can synthesize reproductive hormones, and that cognitive impairment particularly occurs during reproductive senescence, it leads to the following research questions; i) which system first enters the aging stage and ii) how the changes are related. Male rats at the ages of 4, 6, 8, 10 and 12 months old were subjected for this study. Blood samples were collected for serum testosterone (T) and luteinizing hormone (LH) assays by enzyme-linked immunosorbent assay (ELISA) techniques. Testes, seminal vesicle, prostate gland and …

Arthropod Diets In Chihuahuan Desert Snakes, Victor Manuel Parga
Open Access Theses & Dissertations
Over the past century, studies in herpetology regarding snake diets have been commonly focused on those species that feed or specialize in vertebrate prey items. For those that feed primarily on invertebrates however, little work has been done in determining diet specializations and comparing diets within a community of species. This Thesis focuses on small species of snakes that feed primarily on arthropods in a Chihuahuan Desert community, and will investigate if these are diet generalists or specialists. To this end, stomach contents were examined from preserved specimens of the following species: Rena humilis and Rena dissecta (Leptotyphlopidae), Gyalopion canum …

Birds And Vegetation Structure Of Isolated Juniper And Oak Communities In The Trans-Pecos Chihuahuan Desert., Kayla Garza
Open Access Theses & Dissertations
Birds of the Trans-Pecos region are historically understudied, with most literature covering birds of desert grasslands and scrub in New Mexico and Northern Mexico. A multitude of vegetation communities within the Chihuahuan Desert have also been neglected due to this gap in the research, for reasons including lack of access to public or preserve land in West Texas, and rough terrain. Indio Mountains Research Station (IMRS), is located 42-km southwest of Van Horn, Texas and encompasses many different vegetation communities, including juniper-oak habitats of arroyo and canyon systems. The purpose of this study was to document the bird species utilizing …

Expanded knowledge on an animal’s individual behavior would be useful in reintroduction programs for endangered species around the globe. Currently, reintroduction program criteria focus primarily on physical characteristics such as age, sex, and overall health for the selection of candidates. However, behavioral deficiencies have been found in captive populations, producing adverse effects on reintroduction program success. The giant panda (Ailuropoda melanoleuca) is a species that would benefit from understanding the impact of behavior on reintroduction success. This study focused on the relationship of behavior with kinship, birth weight and age. No significant correlation was found between birth weight …

Dolphins are frequently described as curious animals; however, there have been few systematic investigations of how dolphins behave when they are curious and the extent to which individual differences in curiosity exist in dolphins. Previous research has described individual differences in dolphins’ frequency of interactions with environmental enrichment as well as quantifying curiosity-related traits of dolphins via personality assessments, though behavioral observation and trait rating components have not been part of the same study. The present study describes two different experiments designed to elicit curiosity in 15 bottlenose (Tursiops truncatus) and 6 rough-toothed (Steno bredanensis) dolphins. …
