Emperor penguins threatened by Antarctic sea ice loss
Date:6/20/2012

ents a major collaboration between biologists and climate scientists to assess the potential impacts of climate change on a much-studied species.

Published this week in the journal Global Change Biology, the study was funded in part by the National Science Foundation, NCAR's sponsor. Other funders include WHOI; the French National Agency for Research (ANR) program on biodiversity; the ANR REMIGE program (Behavioral and Demographic Responses of Indian Ocean Marine Top Predators to Global Environmental Changes); the Zone Research Workshop for the Antarctic and Subantarctic Environment (ZATA); the Paul Emilie Victor Institute (IPEV); Alexander von Humboldt Foundation; Marie-Curie European Fellowship; and the U.S. Cooperative Institute for Research in Environmental Sciences visiting fellowship.

-----Vulnerable emperors of the ice -----

At nearly four feet tall, emperors are the largest species of penguin. They are vulnerable to changes in sea ice, where they breed and raise their young almost exclusively. If that ice breaks up and disappears early in the breeding season, massive breeding failure may occur, Jenouvrier says.

Disappearing sea ice may also affect the penguins' food sources. They feed primarily on fish, squid, and krill, a shrimplike animal that feeds on zooplankton and phytoplankton that grow on the underside of ice. If the ice goes, Jenouvrier says, so too will the plankton, causing a ripple effect through the food web that may starve the various species that penguins rely on as prey.

To project how the extent of sea ice in the region will change this century, Holland and another co-author, Julienne Stroeve, a sea ice specialist from the National Snow and Ice Data Center, evaluated 20 of the world's leading computer-based climate models. They selected the five models that most closely reproduced changes in actual Antarctic sea ice cover during the 20th century.
