Population Connectivity Of The Eastern Collared Lizard Crotaphytus Collaris In Arkansas, Whitney Allison Murchison-Kastner

Graduate Theses and Dissertations

Habitat reduction and fragmentation can isolate populations and decrease genetic diversity, making them susceptible to local extirpation. Additionally, geographic barriers can further impede dispersal among populations thus reducing gene flow. Field studies suggest these factors may be responsible for the decline in Eastern Collared Lizard (Crotaphytus collaris) populations in Arkansas. To address the impacts of habitat loss and fragmentation on the Eastern Collared Lizard (C. collaris) in Arkansas, I used DNA fragment analysis to examine genetic diversity, population structure and connectivity among C. collaris populations. I do so herein by employing microsatellite data from 138 adults across 11 loci to …

Evaluating The Effects Of Temperature And Time Of Day On The Activity Of Captive Western Lowland Gorillas (Gorilla Gorilla Gorilla), Jennifer Ryan, William Volpe, Emily Mauser, Laura Dehart, Angela Perretti, Maddy Vandevere

Anthropology & Sociology Student Work

Research on captive animals reaps substantial benefits for conservation, education, and enrichment efforts. As more species become displaced in their natural habitats, it is the job of the researcher to better understand how these animals behave in captivity. To contribute to these efforts, we have been observing the activity budgets of a group of captive western lowland gorillas (Gorilla gorilla gorilla) (1 adult male, 2 subadult males, 2 adult females, 2 infant/juveniles) at the Philadelphia Zoo. Over a period of 16 non-consecutive months, we conducted 30-minute focals with 2-minute scan samples on the gorillas (54.66 hours), recording time of day, …

Pre- And Post-Partum Observations Of Signature Whistle Characteristics Of The Bottlenose Dolphin (Tursiops Truncatus), Robert Dutchen

Theses and Dissertations

This study analyzes whistle usage in an Atlantic bottlenose dolphin during birth. Findings show the mother produces two predominant whistle contours. Congruities between the whistles were compared and showed that the type 1 contour bears structural similarity to the first component of the type 2 contour, indicating combinatorial whistle construction.

Influence Of Group Change On Scent Marking In A Wild Population Of Verreaux’S Sifaka (Propithecus Verreauxi), Julia C. Dickerson

Theses and Dissertations

This study analyzed scent marking rates of wild Verreaux’s sifaka during dispersals to investigate the impact of group changes on olfactory communication. Our results indicate that scent marking is affected by changes in group structure, but other methods of communication likely play a larger role in mediating group membership changes.

Effects Of Artificial Enrichment For Captive Western Lowland Gorilla (Gorilla Gorilla Gorilla) Activity Budgets, Angela Perretti, Rebecca Chancellor

Anthropology & Sociology Student Work

The benefits of enrichment and proper husbandry protocols and their applicability in wildlife research have been important topics of zoological research. Examining activity budgets of various species throughout zoological facilities reap biological, educational and conservation benefits. We collected data on the behavioral responses of five western lowland gorillas (Gorilla gorilla gorilla) (1 adult male, 2 adult females, 2 infants/juveniles) to a novel climbing structure in the outdoor enclosure at the Philadelphia Zoo. Over a period of 53 nonconsecutive months, we conducted 30-minute focals with 2-minute scan samples on the gorillas (488 total observation hours). We recorded frequency of behaviors for …

Body States Of Asian Elephants Within And Around Protected Areas In The Salakpra Wildlife Sanctuary, Kanchanaburi, Thailand, Caitlyn Thai

Theses and Dissertations

Researchers are becoming increasingly aware that studying a species’ landscape of fear or, more broadly, their emotional states, can better inform cognitive questions about how animals navigate their environments. Vigilance behaviors are one way to determine how certain species perceive and respond to risky situations. Due to rapid environmental change, large animals such as elephants are experiencing risky encounters with humans more often than ever before. This study aims to investigate Asian elephants’ expressions of body states and how they might regulate their behavior based on perceived environmental risk or change. Specifically, we investigated the behavioral responses of Asian elephants …

085— Success Of Batesian Mimicry In The Ant-Mimicking Spider Myrmarachne Formicaria, Niaomi Vanalstine, Julia Ophals

GREAT Day Posters

Myrmarachne formicaria (Salticidae) is an ant-mimicking spider which arrived in North America fairly recently, first noted in Ohio in 2001. It is important to understand how M. formicaria will impact other species as it spreads throughout North America. The goal of this study was to assess the success of Batesian mimicry used by the ant-mimicking spider in avoiding predation when in a staged encounter with another salticid spider. Myrmarachne formicaria mimic ants in the movement of their forelegs to resemble ant antennae, as well as bob their abdomen. The predator spiders were placed in a small petri dish with either …

Conspecific Aggression Of Invasive Crayfish, P. Clarkii, In Response To Chemical Cues, Elyse Vetter, Elise Dearment, Audrey Fontes, Gary Bucciarelli, Lee Kats

Seaver College Research And Scholarly Achievement Symposium

Red Swamp Crayfish, Procambarus clarkii, have caused vast damage to the stream ecosystem of the Santa Monica Mountains, following their invasive introduction. Through their extensive eating habits, high levels of aggression, and responsiveness to environmental stimuli, P. clarkii have a tremendous impact on the success of native species in the Santa Monica Mountains. With exposure to chemical cues, crayfish are able to perceive threats and react accordingly. To determine the extent of such chemoreception, pairs of P. clarkii were tested in the laboratory for conspecific aggression in the presence of native newt, native frog, and conspecific alarm cues. The …

The Effects Of Symbiote Ostracods On Invasive Crayfish Behavior, Audrey Fontes, Elyse Vetter, Gary Bucciarelli, Lee Kats

Seaver College Research And Scholarly Achievement Symposium

Invasive crayfish, Procambarus clarkii, are known to negatively impact the biodiversity of Santa Monica Mountain streams. Small symbiotes, ostracods, live on Procambarus clarkii in some local streams. However, their effect on the behaviour of invasive crayfish is unknown. We used an aqueous chlorobutanol solution to remove ostracods from crayfish. We paired control crayfish with those that had ostracods removed and scored aggressive interactions. Crayfish without ostracods were found to be significantly more aggressive towards crayfish with ostracods. When we compared feeding behavior, we found that crayfish without ostracods consumed food more quickly than control crayfish. We again subjected crayfish …

Ecology Of Patas Monkey (Erythrocebus Patas) In Buffer Zone Ranges, Old Oyo National Park, Nigeria, Shafiu Kilishi Halidu, Olaoluwa Ayodeji Adebayo, Jude Chikezie, Azeez Olalekan Ibrahim, Olushola Emmanuel Adedeji

Journal of Bioresource Management

The buffer zones of Nigerian protected areas are poorly managed. Patas monkey (Erythrocebus patas) was studied in fact owing to its dearth of information on its ecology and existence in South-West Nigeria National Park. Therefore, it was necessary to examine E. patas spatial distribution and population structure in the Old Oyo National Park buffer zone ranges, situated in South-West Nigeria and as well know its dietary uptake alongside delineating its various activities. Observations were positioned on direct census methods. A total of 60 individuals of E. patas (23 female, 21 male, and 16 young individuals) were sighted within …

Kleptoparasitic Hawk-Dove Games, Isabella H. Evans-Riester, Chasity T. Kay, Karina L. Ortiz-Suarez, Jan Rychtář, Dewey Taylor

Spora: A Journal of Biomathematics

The Hawk-Dove game is a classical game-theoretical model of potentially aggressive animal conflicts. In this paper, we apply game theory to a population of foraging animals that may engage in stealing food from one another. We assume that the population is composed of two types of individuals, Hawks and Doves. Hawks try to escalate encounters into aggressive contests while Doves engage in non-aggressive displays between themselves or concede to aggressive Hawks. The fitness of each type depends upon various natural parameters, such as food density, the mean handling time of a food item, as well as the mean times of …

Anticipation Induces Polarized Collective Motion In Attraction Based Models, Daniel Strömbom, Alice Antia

Northeast Journal of Complex Systems (NEJCS)

Moving animal groups are prime examples of natural complex systems. In most models of such systems each individual updates its heading based on the current positions and headings of its neighbors. However, recently, a number of models where the heading update instead is based on the future anticipated positions/headings of the neighbors have been published. Collectively these studies have established that including anticipation may have drastically different effects in different models. In particular, anticipation inhibits polarization in alignment-based models and in one alignment-free model, but promotes polarization in another alignment-free model. Indicating that our understanding of how anticipation affects the …

Journal of Bioresource Management

This study was focused on the ecology and behavior of the White-headed Duck (Oxyura leucocephala) at Garaet Hadj Tahar (Guerbes-Sanhadja, North East of Algeria). Sampling was carried out during two wintering seasons (2017-2018 and 2018-2019). High number of this duck was recorded in 2018/19 (350 individuals). We observed two Oxyura population, the first sedentary, and the second, hosted the Garaet during the wintering season. Diurnal time budget was dominated by the comfort activities the sleeping with a rate of 39.13%. Following by swimming (37.76%), feeding (17.59%) grooming (4.58%), courtship ritual (0.56%) and flying (0.38%). The feeding of white-headed …

Sex-Specific Variation Of Social Play In Wild Immature Tibetan Macaques, Macaca Thibetana, Tong Wang, Xi Wang, Paul A. Garber, Bing-Hua Sun, Lixing Sun, Dong-Po Xia, Jin-Hua Li

Biology Faculty Scholarship

Theories proposed to explain social play have centered on its function in establishing social relationships critical for adulthood, its function in developing motor skills needed to survive, and promoting cognitive development and social learning. In this study, we compared variations in social play among infant and juvenile male and female Macaca thibetana. Given that this species is characterized by female philopatry and male dispersal, we hypothesized that immature females use social play as a mechanism to develop bonds that persist through adulthood whereas immature males use play to develop social skills needed to successfully enter new groups. The results indicated …

Effects Of Hierarchical Steepness On Grooming Patterns In Female Tibetan Macaques (Macaca Thibetana), Dong-Po Xia, Xi Wang, Paul A. Garber, Bing-Hua Sun, Lori K. Sheeran, Lixing Sun, Jin-Hua Li

Anthropology and Museum Studies Faculty Scholarship

Hierarchical steepness, defined as status asymmetries among conspecifics living in the same group, is not only used as a main characteristic of animal social relationships, but also represents the degree of discrepancy between supply and demand within the framework of biological market theory. During September and December 2011, we studied hierarchical steepness by comparing variation in grooming patterns in two groups of Tibetan macaques (Macaca thibetana), a primate species characterized by a linear dominance hierarchy. Using a focal sampling method, we collected behavioral data from two provisioned, free-ranging groups (YA1 and YA2) at Mt. Huangshan, China. We found …

Sexual Interference Behaviors In Male Adult And Subadult Tibetan Macaques (Macaca Thibetana), Kui-Hai Pang, Amanda K. Rowe, Lori K. Sheeran, Dong-Po Xia, Lixing Sun, Jin-Hua Li

Anthropology and Museum Studies Faculty Scholarship

Male nonhuman primate sexual interference, which includes copulation interruption and copulation harassment, has been related to reproductive success, but its significance has been challenging to test. Copulation interruption results in the termination of a copulation before ejaculation, whereas copulation harassment does not. We conducted this study using the all-occurrence behavior sampling method on sexual interference behaviors of seven adult and four subadult male Tibetan macaques (Macaca thibetana) in mating and non-mating seasons at Mt. Huangshan, China, from August 2016 to May 2017. Our results showed that males’ individual proportion of copulation interruption and harassment was higher during the mating season …

Natural And Experimental Noise Affects Acoustic Communication In Songbirds, Veronica Arlene Reed

Master's Theses

Background noise is ubiquitous and can impair acoustic communication and influence signaling behavior in animals. Despite evidence demonstrating myriad effects of anthropogenic noise on animal communication, precisely how natural background noise influences communication and behavior remains unclear. Yet, natural sources of background noise, such as rushing rivers or crashing ocean surf, share similar power spectra to sources of anthropogenic noise and can occur at high amplitudes, potentially masking acoustic signals.

To investigate the effects of water-generated noise on songbird behavior, we experimentally broadcast landscape-level playbacks of ocean surf and river noise in coastal California, USA, and riparian habitat in Idaho, …

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 …

Behavioral Analysis Of The Cryptoprocta Ferox In An Ex-Situ Condition, Emilie Alfonso

The Pegasus Review: UCF Undergraduate Research Journal

Fossas (Cryptoprocta ferox) are the top, endemic predators of Madagascar. Their populations are dwindling and are reported as “Vulnerable” by IUCN. In an effort to combat this, zoological facilities have placed the species on a captive breeding program. This study focuses on concerns one of those zoos had about their captive C. ferox. The purpose of this study was to collect activity budgets on the C. ferox to determine if there is a change in behavior due to construction occurring around the C. ferox’s habitat, analyze behavior changes during estrus, determine any behavior changes, as well …
