Bears are known for being devoted and protective of their baby cubs, but research from the University of New Hampshire shows that they may also play a significant role in shielding gray fox from predators like coyotes, who compete with the fox for food and space. The research is one of the first studies to show how black bears provide a buffer to allow other, smaller carnivores to safely co-exist.
Many animals feign death to try to escape their predators, with some individuals in prey species remaining motionless, if in danger, for extended lengths of time.
Grassroots knowledge from indigenous people can help to map and monitor ecological changes and improve scientific studies, according to Rutgers-led research. The study, published in the Journal of Applied Ecology, shows the importance of indigenous and local knowledge for monitoring ecosystem changes and managing ecosystems. The team collected more than 300 indicators developed by indigenous people to monitor ecosystem change, and most revealed negative trends, such as increased invasive species or changes in the health of wild animals. Such local knowledge influences decisions about where and how to hunt, benefits ecosystem management and is important for scientific monitoring at a global scale.
Aerial drone footage provides the first evidence of adult blacktip sharks using shallow waters as a refuge from a huge predator – the great hammerhead. Before this study, documentation of adult sharks swimming in shallower waters to avoid predation did not exist. Unmanned aerial vehicles enable scientists to unobtrusively observe behaviors in the wild, providing insight into seldom-seen predator-prey interactions. When it comes to sharks, this “hammerhead” time video proves you “can’t touch this.”
