Integrating Black Bear Behavior, Spatial Ecology, And Population Dynamics In A Human-Dominated Landscape: Implications For Management, Jarod D. Raithel
Integrating Black Bear Behavior, Spatial Ecology, And Population Dynamics In A Human-Dominated Landscape: Implications For Management, Jarod D. Raithel
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The American black bear (Ursus americanus) has made a robust recovery within the human-dominated, social-ecological systems characterizing the Mid-Atlantic United
States. For example, in northwestern New Jersey (NJ), USA, black bear abundance increased from an estimated 450-500 in 1996 to 3200-3400 in 2010. Bear recovery
coincided with increasing human populations, coupled with shifting settlement patterns toward sprawling suburban communities. Consequently, conflicts have rapidly proliferated over the past three decades and resulted in >1400 incidents of verified property damage, >400 livestock kills, >250 pet attacks and/or kills, seven human attacks and one human fatality since 2001. The New Jersey …
The Evolution Of Fear Ecology: A Fruit Fly (Drosophila Melanogaster) Perspective, Itachi Mills
The Evolution Of Fear Ecology: A Fruit Fly (Drosophila Melanogaster) Perspective, Itachi Mills
Theses
Several mechanisms underlie how evolutionary lineages respond to predation pressures or predation risk. Further mechanisms link evolutionary predation responses to how animals forage, or find mates. However, gaps remain in our understanding about how predation and foraging interact in an evolutionary context.
In my first chapter, I elaborate on how predation and foraging relate in to one another in ecological, evolutionary and behavioral contexts. I start out with an overview of fear ecology. Then, I outline how trade-offs influence the evolution of morphological, chemical and behavioral responses to predation. I further elaborate on how these trade-offs influence reproduction. Finally, I …
Does Genotype Correlate With Phenotype? Evaluating Ruffed Lemur (Varecia Spp.) Color Vision Using Subject Mediated Automatic Remote Testing Apparatus (Smarta), Raymond Vagell
Theses and Dissertations
Ruffed lemur (Varecia spp.) color vision research was conducted using a multidisciplinary approach: psychophysics, genetic analysis, technology, and animal training. The behavioral manifestation of Varecia spp. trichromacy was shown using a touchscreen apparatus (SMARTA). Trichromats performed better than dichromats when discriminating red from green (G2 = 78.10, p < 0.001).
The Behavior And Ecology Of Cursorial Predators And Dangerous Prey: Integrating Behavioral Mechanisms With Population-Level Patterns In Large Mammal Systems, Aimee Tallian
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Driving into Yellowstone National Park for the first time is a moving experience. Gazing over the sweeping landscapes, seeing a geyser erupt 80 feet into the air, and having your first ‘wildlife encounter’, whether that be a 2 ton bull bison aggressively wallowing on his dirt mound, snorting and kicking up dust, or watching a pack of 6 wolves move through a valley off in the distance, pausing to howl in search of their companions. Yellowstone staff wishes to manage our park in a way that preserves these remarkable experiences. In order to effectively manage this dynamic ecosystem, it is …
