Ain’t Nothing like Family—Female Brown Bears Share Their Home Range with Relatives
Sociality in animal populations is a continuum, and interactions between conspecifics are meaningful for all vertebrates. Ignorance of social structures can lead to misunderstanding their ecology and, consequently, to unsuccessful species management. Here, we combined genetic and spatial data on rad...

Sociality in animal populations is a continuum, and interactions between conspecifics are meaningful for all vertebrates.
