Energy requirements make Antarctic fur seal pups vulnerable to climate change
Date:3/21/2012

also important in determining a pup's energy throughput, including the pup's size and condition at birth and environmental factors like weather.

"If climate change models are correct and the Antarctic Peninsula gets windier and wetter weather, this may influence how much energy is available for growth," McDonald said. "Changes in prey availability and climate may lead pups to conserve energy by sacrificing the development of foraging skill or to wean at a lower mass or body condition, resulting in negative impacts on the ability to transition successfully to nutritional independence."

McDonald hopes the research will lead to better predictions about how a changing environment may ultimately affect young seals and seal populations.
