Which has more biodiversity, the Galapagos or the sub-Antarctic island South Georgia? Surprise, surprise

ScienceDaily (May 25, 2011) — The first comprehensive study of sea creatures around the sub-Antarctic island of South Georgia reveals a region that is richer in biodiversity than even many tropical sites, such as the Galapagos Islands. The study provides an important benchmark to monitor how these species will respond to future environmental change.

Reporting recently in the online journal PLoS ONE, the team from British Antarctic Survey (BAS), funded by the British Government's Darwin Initiative and the South Georgia Heritage Trust, describe how they examined over 130 years of polar records. About 1500 species were recorded showing South Georgia and its surrounding islands to be the richest area for marine life in the Southern Ocean.

Lead author Oliver Hogg from BAS says, "The biodiversity of South Georgia exceeds that of its nearest rivals such as the Galapagos and Equador in terms of the number of species inhabiting its shores. During the breeding season it hosts the densest mass of marine mammals on Earth."
