Home-range size across grid-cell sizes

Grid-based home-range estimates depend on the spatial resolution of the grid. Here we examine how the estimated home-range size changes as grid-cell area increases.

library(gridHR)

hr_cell_size(
  gibbons,
  min = 50,
  max = 10000,
  interval = 500,
  cell_shape = "hex",
  title = "Grid-based home-range of gibbons across hexagonal cell areas"
)

The figure shows that home-range size stabilizes at approximately 0.5 ha (5,000 square meters) hexagonal cell area, suggesting that larger cells provide little additional change in the estimated home-range size.
