A new study challenges widely held beliefs about the impact of wolves on the Yellowstone ecosystem, pointing out methodological errors in previous research. Scientists note that the effects of wolf reintroduction have been less pronounced and more varied than previously thought.
An experiment in the Bavarian Forest showed that the scent of a lynx effectively deters deer from young trees, unlike the scent of a wolf. This confirms the important role predators play in maintaining forest ecosystems.
A new study has revealed that giant sharks emerged and took on the role of top marine predators much earlier than previously thought, successfully competing with ancient marine reptiles.
A new study has found that high-ranking baboons sleep less and more restlessly than their subordinates, sacrificing sleep quality for safety in the center of the group. Leadership in the animal kingdom is associated with chronic sleep deprivation.
