Introduced rats on Guafo Island (Chile) and their potential impact on Sooty Shearwater Puffinus griseus.

摘要: vulnerable to introduced predators. Sooty Shearwater (Puffinus griseus) form large breeding colonies in southern islands of Chile, South America. However, there are not studies determining the threat degree this seabird associated kind This article reports presence rats largest colony sooty shearwater world (Isla Guafo, Chile), discussing potential impact generated by over seabirds. Introduction Seabirds that inhabit and breed on highly predation mammals such as (Rattus rattus, R. norvegicus exulans) (Jones et al. 2008), mice (Mus musculus) (Wanless 2007) feral cats (Felis catus) (Imber 1975). The is particularly acute lack any native mammalian predators and, a consequence, seabirds have limited or non antipredatory strategies (Dulloo 2002).
