Duke study examines evolutionary consequences of bluebird aggression

...nt itself is always changing," as fires, pests and weather remake western bluebirds' surroundings. Consequently, the link between behavior and settlement patterns is dynamic and ever-changing. "This study does suggest that behavior can play a leading role in evolutionary processes," Duckworth said. She plans...

Same species responds differently to same warming, depending on location

...e, Gilman and her co-authors show that even if the weather warms the air and water the same amounts in one area as another, the actual effect on mussel body temperatures can vary because of local climate. For example, in Washington, air temperature appears to be more important in driving mussel temperature w...
