Spatial scales of habitat selection decisions: implications for telemetry-based movement modeling
Movement influences a myriad of ecological processes operating at multiple spatial and temporal scales. Yet our understanding of animal movement is limited by the resolution of data that can be obtained from individuals. Traditional approaches implicitly assume that movement decisions are made at th...

Movement influences a myriad of ecological processes operating at multiple spatial and temporal scales.
