| 요약 | The global expansion of human activity has had profound consequences for wildlife. Research has documented the effects of widespread habitat destruction and defaunation on species and ecosystems, but the more subtle pathways through which humans alter the natural world have largely escaped quantification. Much like apex predators, humans can instill strong fear in wild animals, which may adjust their activity to avoid contact with humans. In this dissertation, my collaborators and I examine pathways through which human disturbance, predation risk, and environmental heterogeneity influence animal behavior and distribution. We review the literature and synthesize theory to develop a novel framework for studying landscapes of fear, and we apply this framework in a global meta-analysis and field studies from California and Mozambique to understand how large mammals perceive and respond to spatial and temporal patterns of risk from humans and carnivores. We consider links between risk and response in complex systems with multiple predators or multiple prey species, and we explore ecology of fear dynamics in the context of seasonality, human disturbance, and restoration. Together, this work integrates disciplines of behavioral ecology, community ecology, and landscape ecology, applying predator-prey theory to understand the role of humans in ecological communities. By elucidating behavioral pathways linking human disturbance to wildlife community dynamics, this research contributes to our understanding of wildlife ecology in human-dominated landscapes and highlights mechanisms for human-wildlife coexistence. |
