Botswana’S Elephant-Back Safari Industry – Stress-Response In Working African Elephants And Analysis Of Their Post-Release Movements, Tanya Lama
Masters Theses
Understanding how African elephants (Loxodonta africana) respond to human interactions in ecotourism operations is critical to safeguarding animal and human welfare and sustaining wildlife ecotourism activities. We investigated the stress response of elephants to a variety of tourist activities over a 15-month period at Abu Camp in northern Botswana. We compared fecal glucocorticoid metabolite (FGM) concentrations across three elephant groups, including: eight elephants in an elephant-tourism operation (Abu herd), three elephants previously reintroduced back into the wild from the Abu herd, and wild elephants. There were no differences in FGM concentrations between the three groups of elephants. The highest observed …
Habitat Use And Seasonal Movement Patterns Of Four-Toed Salamanders (Hemidactylium Scutatum) In Massachusetts, Kimberly O. Vitale
Habitat Use And Seasonal Movement Patterns Of Four-Toed Salamanders (Hemidactylium Scutatum) In Massachusetts, Kimberly O. Vitale
Masters Theses 1911 - February 2014
Understanding the movement phenology of the four-toed salamander (Hemidactylium scutatum) is essential to guide management practices. I examined the relationship between environmental variables and the directionality, timing, and magnitude of four-toed salamander movements at two locations in eastern Massachusetts. Four-toed salamanders move from upland habitats to wetland areas in early spring and move away from wetlands in late spring. Adult movements increased with more precipitation and less moon light. Juvenile movements were similarly affected, and in addition they were more likely to move when temperatures were warm and days long. My results can be used to implement management …
Status, Movements, And Habitat Use Of Moose In Massachusetts, David W. Wattles
Status, Movements, And Habitat Use Of Moose In Massachusetts, David W. Wattles
Masters Theses 1911 - February 2014
Moose (Alces alces) have been re-established in much of the historic range in the northeastern United States. Recently the southern edge of the species ranges has been extended southward into southern New England and northern New York from established populations in northern New England. The southern expansion raised questions as to the ability of this northern species to cope with higher temperatures, areas densely populated by humans, and different forest types further south. In light of these recent developments, we conducted a literature search on moose in the northeastern United States and distributed a questionnaire and conducted phone …
