DOWNLOAD EBOOKAfrican elephant (Loxodonta africana) population growth in Kruger National Park (KNP) and the subsequent environmental impacts, such as decreased biodiversity, has raised conservation concerns demanding thorough understandings about elephant behavior interplay with landscape dynamics. This thesis aims to examine how African elephant movement is affected by landscape changes in KNP from a combined geographic and ecological perspective. A landscape "Availability-Suitability-Connectivity" framework was employed to systematically evaluate landscape dynamics related to elephant movement by integrating GPS tracking data, satellite imagery and habitat suitability modeling as inputs. Following this framework, the study developed an individual-based model to simulate elephant movements and resulting landscape networks under various landscape conditions. Taken together, this study highlighted appealing features of coupling geospatial technologies and ecological modeling methods to assess relationships between animal movement and landscape connectivity, to evaluate potential impacts of landscape changes, and to inform effective conservation practices.
