Electronic Theses and Dissertations
Environmental degradation is the legacy of the Anthropocene era and maintaining ecosystem health is a major challenge for managers globally. Restoration ecology aims to improve ecosystem health through reintroduction and rehabilitation of important native species to maintain or increase biodiversity and achieve stable and resilient communities. Non-native species may affect reintroduction efforts through interactions in time and space. This dissertation proposes that understanding the spatio-temporal ecology of two species along with their energy demands and growth (i.e., bioenergetics), would provide key clues for untangling the complexities of species interactions and further the knowledge on influences of non-native species on native …

Our ability to identify and understand the relationships and distributions of organisms in nature is key to exploring the rich tapestry of life seen on Earth. The term "niche" describes how animals partition resources in space and time, shaped by behavioural choices and environmental conditions. Iterations of niche over time have focused on different aspects of a species' ecological characteristics, from Grinnell’s initial study of songbird distribution (‘spatial niche’) in 1917 to Elton’s description of functional attributes shaping trophic position (‘trophic niche’). The fusion of these niche definitions formed Hutchinson’s n-dimensional niche hypervolume. The coexistence of …
