• Description:
  1. A long-standing goal in ecology is to describe an animal’s home range or utilization density (UD) without complete knowledge of the animal’s movement. There are a number of methods available to calculate a UD from telemetry data, but the most com- mon methods limit the UD to cover areas where the animal was observed during track-ing, and do not account for preferential use of different habitats (resource selection). 2. The limiting distribution of a continuous-time Markov chain (CTMC) matches the intuitive understanding of a UD for an animal following a CTMC movement model. By modelling continuous-time movement through discrete-gridded space we can infer environmental effects on animal movement and then predict a UD over the
