Grid-Based Home-Range Analysis and Radial Space-Use Profiles

Tools for estimating and exploring animal home ranges from geographical locations using regular spatial grids of square or hexagonal cells; see Ford and Krumme (1979) . The package includes grid-based home-range estimation across different cell sizes, analyses of the relationship between grid-cell size and home-range area and spatial connectivity, and rarefaction analyses to evaluate how home-range estimates change with increasing numbers of locations. It also introduces a novel radial approach for characterizing the internal organization of space use by quantifying how space-use intensity changes with increasing distance from the centre toward the periphery of the home range.
