Community distance sampling models allowing for imperfect detection and temporary emigration
Yuichi Yamaura, J. Andrew Royle
2017, Ecosphere (8) 1-15
Recent developments of community abundance models (CAMs) enable us to analyze communities subject to imperfect detection. However, existing CAMs assume spatial closure, that is, that individuals are always present in the sampling plots, which is often violated in field surveys. Violation of this assumption, such as in the presence of...
