A new strategy for diagnostic model assessment in capture-recapture [PDF]

open access: yes, 2016
Common to both diagnostic tests used in capture–recapture and score tests is the idea that starting from a simple base model it is possible to interrogate data to determine whether more complex parameter structures will be supported.

Annual survival estimation of migratory songbirds confounded by incomplete breeding site-fidelity: study designs that may help [PDF]

open access: yesAnimal Biodiversity and Conservation, 2004
Many species of bird exhibit varying degrees of site–fidelity to the previous year’s territory or breeding area, a phenomenon we refer to as incomplete breeding site–fidelity. If the territory they occupy is located beyond the bounds of the study area or
