Studies in Yellowstone Park have shown that ravens search for food by remembering locations where wolves have hunted successfully, rather than by following the predators themselves. These birds create mental maps of the area and deliberately return to promising spots.
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.
The study found that even minor earthquakes can temporarily increase the resources available to underground microbes by altering the chemical composition of aquifers. This discovery offers new insights into how life can survive deep within the Earth and potentially on other planets.
