![]() ![]() Using mixed effects models, I test hypotheses about elephant range size in relation to sex, species, region, vegetation phenology and quantity, protected areas, human footprint and terrain (Chapter 6). What does tracking data tell us about the factors influencing elephant range size across Africa? I present a comparative analysis of elephant range area measured in West, Central, East and Southern Africa. I also identified corridors and core areas of conservation priority (Chapter 5).ĥ. The Gourma elephant's range was found to exceed those reported elsewhere in Africa and movements were correlated with patterns of rainfall and vegetation phenology. What does tracking data tell us about the movement patterns of the Sahelian elephants in Mali? I use GPS tracking to study elephants in the Gourma, Mali to understand this unique and important population. I demonstrate its performance in relation to other space-use estimators (Chapter 4).Ĥ. ![]() Can we estimate wildlife space-use from tracking data? I develop the Elliptical Time-Density model to estimate an animal's utilization distribution from tracking data where parameters are directly linked to species biology. Four algorithms identify when wildlife slow or stop moving or cross into or near to spatial objects (Chapter 3).ģ. Can we leverage real-time tracking data for management and conservation? I present a monitoring system that implements continuous analysis of elephant GPS tracking data streams to identify positional and movement-based geospatial alert conditions. I demonstrate its utility by analyzing tracking datasets collected from 247 elephants (Chapter 2).Ģ. What is an appropriate method to collect, store, disseminate, visualize and analyze elephant tracking data? I present a system (Loxobase) designed to provide an efficient and scientific basis for the treatment of wildlife tracking data. To assemble the seat rail, first retrieve the two beveled pieces of scrap that you saved earlier and position them on the jig (Photo 1). Drill and countersink the arm rail, then attach it with glue and 1-1/4 in. Using GPS tracking data, I address five research topics that contribute new information to the geospatial analysis of tracking data, to elephant movement ecology, and conservation :ġ. Put the arm rail in position, mark the opposite end, and make the opposing miter cut so the rail fits tightly. cyclotis) are important species for geospatial study given their ecological role as megaherbivores, their large home ranges which pose challenges for conservation, and the ongoing ivory crisis. African elephants (Loxodonta africana and L. ![]()
