In a general context of climate change, researchers have revealed the impact of ocean cycles, such as the Pacific decadal oscillation and El Niño, on the survival of the Nazca booby. Their research shows for the first time that long cycles directly affect the survival of adult populations.
For decades, researchers have thought that access to food determined the brood size of birds. Now, biologists have discovered a completely new explanation: the body temperature of small birds can increase by more than 4°C to exceed 45°C when they are feeding their young. Larger broods would require more work, resulting in even higher body […]
