Consequences of ignoring group association in spatial capture-recapture analysis
Richard Bischof, Pierre Dupont, Cyril Milleret, Joseph Chipperfield, J. Andrew Royle
2020, Wildlife Biology (2020)
Many models in population ecology, including spatial capture–recapture (SCR) models, assume that individuals are distributed and detected independently of one another. In reality, this is rarely the case – both antagonistic and gregarious relationships lead to non-independent spatial configurations, with territorial exclusion at one end of the spectrum and group-living...
