Two new studies examining gray wolves in California paint a complex picture of life on the state's ranching landscapes: Wolves eat cattle more than anything else, and the presence of the predators causes significant stress ...
A new international study led by researchers at the University of Oulu, Finland, shows that wolves living in different parts of the world are not anatomically identical. Their skulls differ in shape and size according to ...
Movement data from wild predator–prey encounters and controlled human catch-tag games have been combined to create realistic simulations of high-intensity movement dynamics and energetics—before being transformed into a publicly ...
A rat first frees a cagemate rat and then shares food with it. Is this animal just as empathetic as humans? In an American study from 2011, researchers observed that rats first freed their fellow rats from a cage and then ...
Throughout human ecological history, we have played a variety of roles within ecosystems around the world. In this so-called Anthropocene era, genomic innovations have given us new and powerful ways to influence the environment ...
When trying to attract and recognize potential mates, animals are known to rely on various signals, traits and behaviors. In the case of birds, these signals can typically include a wide range of sounds—such as trills, whistles, ...
