Staff Perceptions Of Responsibility And Implementation Of Cognitive Enrichment For Non-Human Primates In Zoo Settings, Ember Nevada Toth
Staff Perceptions Of Responsibility And Implementation Of Cognitive Enrichment For Non-Human Primates In Zoo Settings, Ember Nevada Toth
All Master's Theses
In zoos, caregivers have considered enrichment as vital for their animal collections’ physical health and development. Since primate species are endangered and continue to decline in numbers in their natural habitat, zoos are steadily becoming the only places we can view and learn about them. In today’s zoos, cognitive enrichment—which falls into overlapping categories of enrichment and does not yet have a universally accepted definition—is either absent or inconsistently offered. Providing challenges to stimulate cognitive well-being has been found to influence the overall welfare of captive primates. Cognitive enrichment is considered very important according to zookeeper surveys but is not …
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 …
Captive Chimpanzees' (Pan Troglodytes) Night-Time Enrichment Selection And Use, Katherine M. Mcdonald
Captive Chimpanzees' (Pan Troglodytes) Night-Time Enrichment Selection And Use, Katherine M. Mcdonald
All Master's Theses
Captive chimpanzees (Pan troglodytes) engage with enrichment objects extensively during the daytime, yet relatively little is known regarding their use of available enrichment at night. This study examined night-time enrichment use in three adult chimpanzees at the Chimpanzee and Human Communication Institute. Every evening, the chimpanzees received a variety of enrichment objects. The objects belonged to one of nine categories. Night-vision video cameras recorded the chimpanzees’ night-time behaviors every Monday through Thursday from July 9 to August 9, 2012 (Carner et al., 2013). The present study used a focal animal, instantaneous sampling method (Martin & Bateson, 2007) to …
Effects Of Visitors And Enrichments On Behavior Of Captive Red Wolves’ (Canis Rufus) At The Great Plains Zoo, Sioux Falls, South Dakota, Kylee S. Shotkoski
Effects Of Visitors And Enrichments On Behavior Of Captive Red Wolves’ (Canis Rufus) At The Great Plains Zoo, Sioux Falls, South Dakota, Kylee S. Shotkoski
Electronic Theses and Dissertations
Red wolves (Canis rufus) are the first animals to maintain a wild population from captive, released individuals. A captive breeding program for red wolves was started before complete extirpation, and 4 breeding pairs were released in Alligator River National Wildlife Refuge (North Carolina) in 1987 and a small wild population still exists there. Currently, there are several captive breeding facilities for red wolves within the Species Survival Plan (SSP) program. The Great Plains Zoo in Sioux Falls, South Dakota participates in the SSP program. My study was initiated to create a natural history background and evaluate interaction between …
Chimpanzee (Pan Troglodytes) Responses To Visitors Using Chimpanzee-Friendly Behaviors, Daniella Bismanovsky
Chimpanzee (Pan Troglodytes) Responses To Visitors Using Chimpanzee-Friendly Behaviors, Daniella Bismanovsky
All Master's Theses
Many studies suggest that zoo visitors are a cause of stress among animals; among primates, visitor presence can lead to an increase in aggressive displays, time spent non-visible to the public, and a decrease in overall activity. This study tested the effectiveness of using species-specific behaviors among a group of captive chimpanzees. There were 2 conditions: a control, and an experimental condition in which visitors were asked to adopt a stooped posture or lean on the railing, and show a chimpanzee play face. The visitors stooped their posture, sat, and leaned on the railing significantly more in the experimental condition …
