| The comparison of new and historic census counts of pygoscelid penguins and other seabird populations on Petermann Island (65°10'S, 64°10'W) and neighboring islands shows several trends consistent with theories of climate-mediated change in the Antarctic Peninsula. Long-term data on the number of gentoo nests on Petermann Island show that their abundance has increased about 30 times from beginning of the 20th century, 3–4 times from 1970–80, and has doubled since 1990. In contrast, the abundance of Adélie penguin nests on Petermann Island diminished about four times since 1970 and two times since 1997. The newly discovered gentoo penguin rookeries on Moot Point, the Yalour Islands, Galindez Island and Cape Tuxen represent the southernmost locations where... |
