Bering Sea study finds prey density more important to predators than biomass
Date:1/3/2013

d kittiwakes at St. Paul, St. George and Bogoslof Islands. The birds would capture local prey to feed their chicks during the day, but make numerous long flights at night to gorge on energy-rich, deep-water prey before returning to their nests to feed their chicks.

"It is a trade-off strategy," said Benoit-Bird, a 2010 recipient of a MacArthur Fellowship. "They feed themselves in one place and nourish their offspring from another."

This concept of prey "patchiness" can change rapidly, the researchers noted. Pollock aggregated only when the number of individuals in an area reached a certain threshold; below that threshold, they swam as individuals.

"If the population is sufficiently diffuse, the pollock don't aggregate and that could spell trouble for species that prey upon them," Heppell said. "A 10 percent shift in the number of fish could change how the entire stock behaves and have a major impact on the birds, seals and other predators."
