Animals that live in groups can affect their populations and ecosystems in complicated ways, so scientists need good methods to measure how many groups there are, how big they are, and how many individuals live in them. Traditional spatial capture–recapture (SCR) methods can estimate either group density or individual density, but they often give biased results for group-living species because
Ecologists use spatial capture–recapture (SCR) models to study whole animal populations and movement models to study how individual animals behave. Even though individual movement shapes population patterns, these two approaches have mostly been developed separately. Movement models usually focus only on individuals, while SCR models focus on populations but simplify how animals move. The authors argue that combining these two
