February 2012: Twelve per cent of marine species surveyed in the Gulf of California, the coasts of Panama and Costa Rica and the five offshore oceanic islands and archipelagos in the tropical eastern Pacific are threatened with extinction, according to a study by IUCN (International Union for Conservation of Nature). Main threats to the region's marine flora and fauna include overfishing, habitat loss and increasing impacts from the El Nino Southern Oscillation.
Released this week, the study is the first IUCN Red List of Threatened Species assessment available for all known species of marine shore-fish, marine mammals, sea turtles, sea birds, corals, mangroves and seagrasses in a major marine biogeographic region.
Drastic declines for many speciesThe analysis identifies specific geographic zones where conservation efforts are needed most, including around the mouth of the Gulf of California and the coastlines of Panama and Costa Rica , while also identifying the nature and location of the greatest dangers to marine life.
‘Understanding species vulnerability to major threats is paramount for determining how species and marine environments are likely to respond to one or more simultaneous threats,' says Beth Polidoro, lead author of the study.
