Longest terrestrial migrations and movements around the world

摘要: Long-distance terrestrial migrations are imperiled globally. We determined both round-trip migration distances (straight-line measurements between migratory end points) and total annual movement (sum of the successive relocations over a year) for suite large mammals that had potential long-distance movements to test which species displayed longest both. found caribou likely do exhibit on planet, but, course year, gray wolves move most. Our results were consistent with trophic-level based hypothesis predators would more than their prey. Herbivores in low productivity environments moved herbivores productive habitats. also larger members same guild less smaller members, supporting 'gastro-centric' hypothesis. A better understanding should aid conservation by helping delineate area boundaries determine priority corridors protection preserve connectivity. The magnitude we documented provide guidance scale efforts required assist planning across agency even national boundaries.
