Anthropogenic habitat destruction is one of the major causes of biodiversity loss, driving
species declines across the planet. The resultant human-modified landscapes are not detrimental
for all species. Some species such as small to medium-sized habitat generalist carnivores
(hereafter referred to as ‘mesocarnivores’) are able to thrive because of the exclusion of natural
enemies and anthropogenic sources of food. With the benefits of human-modified landscapes
come novel threats, such as increased exposure to hunting and introduced antagonists.
Mesocarnivores may respond to these threats with changes in space and time use, with potential
consequences for species interactions. In this dissertation, I examine how drivers of
mesocarnivore space and time use align with physical characteristics of the human-modified
landscape and associated factors, and what implications these results have for interactions
between native species. I do this using empirical work across two temperate systems (Chapters
II, III, and IV), and a simulation model (Chapter V).
