Description
Summary:1. Decreasing rate of migration in several species as a consequence of climate change and anthropic pressure, together with increasing evidence of space-use strategies intermediate between residency and complete migration, are very strong motivations to evaluate migration occurrence and features in animal populations. 2. The main goal of this paper was to perform a relative comparison between methods for identifying and characterising migration at the individual and population level on the basis of animal location data. 3. We classified 104 yearly individual trajectories from five populations of three deer species as migratory or non-migratory, by means of three methods: seasonal home range overlap, spatio-temporal separation of seasonal clusters, and the Net Squared Displacement (NSD) method. For migratory cases, we also measured timing and distance of migration and residence time on the summer range. Finally, we compared the classification in migration cases across methods and populations. 4.

The analysis showed in the paper (migration occurrence and related metrics) are based on this dataset, and others related to other population/species.The fields include: sex (sex of the individual animal), acquisition time (timestamp of GPS relocations), UTMx and UTMy coordinates (GPS relocations expressed as UTM easting/northing coordinates), gps_positions_animals_id (unique identifier of the locations), original_animal_id (animal name assigned at captures), animal_year_id (unique individual identifier in the population, and sample unit- i.e. data from one animal in one year).roedeer_bavaria_to_analyse.txtGPS locations_roedeer_NorwayGPS locations of individual roe deer in Norway.
