Hi, The problem of estimating a utilization distribution for a group of animals, based on movement trajectories from each individual is a complex one. Differences in the duration and frequency of locations of individual tracks from multiple animals should be accounted for when calculating such a "population" UD. It's an effort issue. For example: multiple tracks, all regular time series, but all tracks have widely different durations. Questions to address are: can the track from an animal that was observed for a very short time have the same weight as those from another that was observed for 10 times as long? Similarly, can the track of an animal intensively using an area that no other animal uses have the same weight as the rest when calculating a UD for all?
I'm having a hard time finding answers to these questions in the literature, so am wondering if users in the list have any recommendations. Thanks. -- Seb _______________________________________________ AniMov mailing list [email protected] http://lists.faunalia.it/cgi-bin/mailman/listinfo/animov
