Big brothers boss around little brothers. In nature, a dominant male chimpanzee fights off would-be intruders. Even fish and octopi interact within social hierarchies.
These pecking orders have been studied within the behavioral ecology world for almost 100 years. How individuals interact can affect access to food and mates even survival and insights into those behaviors can lead to better management of threatened and endangered populations.

MeowTalk can tell cat owners if their pet is communicating one of nine categories such as being defensive or mating call after they upload its meow. It combines the technology behind Amazon Alexa and Google’s voice assistant and years of cat communication research. The most difficult part, Sanchez says, was simply making the app run at scale for the more than two million phones that downloaded it in t
