Observational Study Of Two Ex Situ North American River Otters (Lontra Canadensis), Julia Rifenberg
Observational Study Of Two Ex Situ North American River Otters (Lontra Canadensis), Julia Rifenberg
The Pegasus Review: UCF Undergraduate Research Journal
Zoos enable the ability to study how captive conditions impact the behaviors of animals. In this study, I observed two North American river otters housed at the Central Florida Zoo to evaluate behavioral changes after the male had been removed from the female for a month-long medical examination. The aim of this study was to 1) determine if mating behaviors were still occurring between the two river otters following the male’s removal and 2) to assess the welfare of the male and female river otters in captivity by observing their interactions and individual behaviors. Observed behaviors were compared to documented …
Effects Of Artificial Enrichment On Western Lowland Gorilla (Gorilla Gorilla Gorilla) Activity Budgets, Angela Perretti
Effects Of Artificial Enrichment On Western Lowland Gorilla (Gorilla Gorilla Gorilla) Activity Budgets, Angela Perretti
West Chester University Master’s Theses
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 the frequency of …
Dominance Or Leverage? An Analysis Of Female Power In Captive Varecia, Jessie E. Birckelbaw
Dominance Or Leverage? An Analysis Of Female Power In Captive Varecia, Jessie E. Birckelbaw
Graduate Research Theses & Dissertations
Lemurs are unusual in that, unlike in most other primates, females have more power than males. This is evident by females receiving priority access to foods and preferred spaces, and frequent grooming. Rebecca Lewis provided a framework to analyze the basis of female power that distinguishes between true dominance and leverage. Dominance is defined as the physical ability to overpower an individual, whereas leverage is the ability to influence others based on intangible resources, such as social currency like grooming or the potential for mating. This study aimed to investigate female power in the critically endangered ruffed lemurs (genus Varecia). …
