Terrestrial mammalian species with extralimital records.

Maps of mammalian occurrence records.
Maps for 39 species of terrestrial Alaskan species with extralimital records (those occurring > 5 km beyond marginal range polygons) harvested from the Global Biodiversity Information Facility (GBIF) [34] are included here (a-am) with range polygons from the International Union for the Conservation of Nature (IUCN) [32], the Alaska Gap Analysis Project (AKGAP) [33], and those based on the minimum bounding geometry of marginal records from MacDonald and Cook [21]. Occurrence records are colored by year of collection with darker colors indicating more recent records and lighter colors indicating older records. Public lands managed by the U.S. National Park Service (green) and U.S. Fish and Wildlife Service (brown) are also shown. All maps are in the NAD83 Alaska Albers projection and have an extent of -173.304°, 51.139° to -112.673°, 67.397°, except maps of Southeast Alaska that are shown in reference to this extent (see inset).

Wind rose graphs depicting the mean distance and direction of a) all extralimital records and b) recent (post-2009) extralimital records relative to each species’ 2009 minimum convex polygon (MCP) range extent for the 5 taxonomic orders of terrestrial mammals considered (Carnivora = blue, Chiroptera = orange, Lagomorpha = purple, Rodentia = yellow, and Eulipotyphla = green).
