The Behaviors Of A Captive Father-Daughter Pair Of Ateles Geoffroyi Geoffroyi, Felicia Gordian
The Behaviors Of A Captive Father-Daughter Pair Of Ateles Geoffroyi Geoffroyi, Felicia Gordian
The Pegasus Review: UCF Undergraduate Research Journal
The Central Florida Zoo and Botanical Gardens intends to introduce new members to the black-handed spider monkeys (Ateles geoffroyi geoffroyi) enclosure. The behavioral analysis of captive animals within their human-made zoo environments is pertinent information for zookeepers before such an introduction can be made. To contribute to that goal, this study observed the behaviors of a father-daughter pair of black-handed spider monkeys. This study observed their vocalizations, habitat utilization, enrichment utilization, conspecific interactions, and interactions with humans to better understand how they interact with their environment as well as their group dynamics. This behavioral baseline can then be utilized to …
Behavioral Analysis Of The Cryptoprocta Ferox In An Ex-Situ Condition, Emilie Alfonso
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 …
Testing For Indirect Benefits Of Polyandry In The Florida Green Turtle, Christopher Long
Testing For Indirect Benefits Of Polyandry In The Florida Green Turtle, Christopher Long
Electronic Theses and Dissertations
Behavioral studies in the green turtle (Chelonia mydas) have indicated that promiscuous mating is commonplace. Though it has been shown that there is much variation in the rate of polyandry (females mating with multiple males), the drivers behind polyandry in this species are unknown. It has been speculated, but never demonstrated, that indirect benefits (fitness benefits resulting from offspring genetic diversity) play a role. However, previous tests of this hypothesis have limited scope of inference due to lack of environmental control. In this thesis, I attempted to study the indirect benefits of polyandry in Archie Carr National Wildlife Refuge (ACNWR) …
Tree Calls Of Three Treefrogs (Hyla Femoralis, H. Gratiosa, And H. Squirella): Analysis Of Environmental, Behavioral, And Acoustic Characteristics, Kristine Schad
Electronic Theses and Dissertations
Male frogs typically call near water at dusk to attract females for breeding. During the breeding season, male treefrogs also emit diurnal "tree calls" or "rain calls" from the tops of trees. Very little is known about tree calls, although many treefrogs use them. Tree calls may be used to attract females, deter males or be triggered by weather conditions favorable for breeding: high temperature and relative humidity, and a drop in barometric pressure. As dusk approaches, male treefrogs continue tree calls from lower in the trees, and if conditions are favorable, jump to the ground and travel to a …
Dispersal Behavior Of Mosquitofish (Gambusia Holbrooki), Shireen Alemadi
Dispersal Behavior Of Mosquitofish (Gambusia Holbrooki), Shireen Alemadi
Electronic Theses and Dissertations
Mosquitofish (Gambusia holbrooki) are native to the southeastern United States but invasive elsewhere, and are dominant predators in many ecosystems that they inhabit. Information on dispersal behavior will help better understand and predict mosquitofish metapopulation dynamics and invasions. I experimentally tested dispersal behavior of individual mosquitofish under a range of laboratory conditions relevant to field situations. Preliminary experiments showed that gender, lighting conditions, hunger and acclimation time did not significantly affect net dispersal rate. Power analysis based on this preliminary experiment determined that 6 replicate fish were sufficient for each subsequent experiment; I used 24 fish, and each fish was …
Monitoring A Potentially Stressful Situation In Captive Western Lowland Gorillas (Gorilla Gorilla Gorilla) Through Analysis Of Behavior And Urinary Cortisol, Douglas Skurski
Electronic Theses and Dissertations
The concept of quantifying animal welfare has received much discussion, in various industries such as agriculture, laboratory, and zoological facilities. Behavioral, physical, and physiological indicators of welfare have previously been used to assess animal welfare; each having advantages and disadvantages, ranging from the practicality of data collection, to the validity of the data and how it is interpreted. Concurrent assessment of multiple measures is a more robust way to examine animal welfare, which utilizes the advantages of each measure, and provides additional information on which to base conclusions and animal care management decisions. This study used measures of behavior and …
The Effects Of Ecotourism On Polar Bear Behavior, Gillian Eckhardt
The Effects Of Ecotourism On Polar Bear Behavior, Gillian Eckhardt
Electronic Theses and Dissertations
Polar bears spend the majority of their lives on the sea ice, where they gain access to seals and mates. In western Hudson Bay, the sea ice melts for three to four months in the summer, and polar bears there are forced onto land. These bears live on their fat reserves for the duration of the iceless period, until temperatures get colder in the fall and freeze up begins. The aggregation of polar bears near Churchill, Manitoba during the ice free period has led to a thriving tourist industry, with a large influx of tourists visiting Churchill in the fall …
