Researchers found Antarctic krill exhibit a daily rhythm of activity, with increased swimming at night and synchronization with seasonal variations. The internal clock helps krill adapt to extreme polar conditions.
A new study of gorillas found that friendly relationships have varying costs and benefits, depending on group size and sex. For example, female gorillas with strong social bonds tend to get ill less often, but have fewer offspring.
A study by scientists at the Smithsonian Tropical Research Institute found that juvenile fringe-lipped bats do not initially differentiate between palatable and unpalatable frogs and toads, but learn to identify toxic species through experience. As they mature, adult bats respond more strongly to palatable prey.
