Global climate change scenarios predict an increase in air and ocean temperatures, storm intensity, storm surge and inundation of low-lying coastal areas and small islands. Projections of changing oceanographic conditions and inundation are at levels that could affect seabird populations including those of the black-footed albatross (Phoebastria nigripes; BFAL). The resilience of BFAL populations in the face of more frequent extreme weather events and nesting habitat loss is therefore a critical issue for wildlife managers. Colony establishment behavior and dispersal biology are poorly understood for BFAL. Despite this uncertainty, management decisions to safeguard BFAL breeding populations in the face of climate...

Conservation of oceanic island species presents many ecological and logistical challenges. The Northwestern Hawaiian Islands (NWHI) include 300,000 km2 of ocean waters and 10 groups of sub-tropical islands and atolls of high conservation value. Designated as Papahanaumokuakea Marine National Monument, the islands provide habitat for four endangered species of terrestrial birds. Despite their protected status, many of these species are faced with the ongoing threat of extinction due to stochastic catastrophes such as disease, invasive mammal introductions, tsunamis, and hurricanes. A longer term threat to NWHI species is sea level rise associated with global climate change. On a 50-year time scale, many low-lying...
