Arboreal locomotion: Movement adapted to climbing and traveling through trees or other elevated structures. Black rats readily climb trees, cables, and building frameworks.
South Asia: The region of Asia comprising the Indian subcontinent and nearby countries. Genetic and historical evidence places important early black rat populations in this region.
Zoonosis: An infectious disease that can pass naturally between animals and humans. Black rats can carry pathogens that threaten people and domestic animals.
Seabird conservation: The protection and recovery of seabirds and the habitats they depend on. Black rats prey on eggs and chicks, threatening seabirds on nesting islands.
