Predators In Paradise: Ecotourism And Predator-Prey Dynamics In Monteverde, Costa Rica, Andrew Cremeans
Undergraduate Theses, Professional Papers, and Capstone Artifacts
The use of camera trap surveys is increasingly common to investigate recurring diel activity of mammals. Investigation into the temporal overlap of mammals can provide unique insights into predator-prey dynamics. Understanding this relationship is essential to effectively manage and conserve both species. Extensive research across the tropics has found that daily activities of mammals were shaped by thermoregulation and trophic location in food webs. Although broad scale studies of daily patterns of mammals have enhanced our understanding of these constraints, many study sites included were remote protected areas under strict conservation measures. Such protected areas often had full complements of …

Understanding Caribou Population Cycles, Jack R. St. John
Undergraduate Theses, Professional Papers, and Capstone Artifacts
The complex population dynamics of caribou (Rangifer tarandus) were studied to determine the patterns of their population cycles and the processes driving them. It is well established, via previous archaeological research and Indigenous knowledge, that large migrating caribou herds found in and around the tundra at northern latitudes experience population boom and busts roughly every several decades. However, the processes driving the dynamics of these cycles are relatively unknown, which makes managing caribou herds for recreational and subsistence harvests difficult. It has been hypothesized that a combination of intrinsic and extrinsic factors shape these cycles, with density-dependence, predation, …

Graduate Student Theses, Dissertations, & Professional Papers
Increasing human impacts on biodiversity highlight the global need for ecological restoration. For many wildlife species, reintroduction is necessary to re-establish populations in parts of their historic range where they have been extirpated. Reintroduction efforts are commonly used to help restore ecosystem integrity, but are often expensive, time consuming, and unsuccessful at generating self-sustaining populations. Thus, a more complete understanding of the factors affecting restoration success is important for ensuring successful outcomes and responsible stewardship. Fishers (Pekania pennanti) are one of the most commonly reintroduced carnivores in North America, but the success of such efforts is highly variable, …
