Why do polar bears approach human infrastructure? The answer is more complex than we thought
Polar bears are intensely curious animals. That curiosity often brings them into contact with people and can put both species at risk from one another.
Animal behavior is the scientific study of the observable actions, interactions, and behavioral patterns of animals, typically investigated within ethology, behavioral ecology, and comparative psychology. It encompasses mechanisms (proximate causes such as neural, hormonal, and genetic control), development (ontogeny and learning), function (adaptive value in survival and reproductive success), and evolution (phylogenetic history and divergence among taxa). Research on animal behavior quantifies activities such as foraging, mating systems, parental care, communication, social organization, and antipredator strategies, often integrating experimental, observational, and modeling approaches to understand how behavior emerges from organism–environment interactions and contributes to fitness and ecological dynamics.

Diving is physiologically challenging for marine animals. Long and deep dives can trigger "anaerobic" (oxygen-less) metabolism in organs other than the heart and brain that causes lactic acid to accumulate. Even though diving ...

Birds sing the most about an hour before dawn, when the air is at its stillest. Theoretically, this enables sounds to travel farther, making song up to 20 times more effective than if sung at midday.
