Full Open Population Capture-Recapture Models with Individual Covariates [PDF]
, 2010 Traditional analyses of capture-recapture data are based on likelihood functions that explicitly integrate out all missing data. We use a complete data likelihood (CDL) to show how a wide range of capture-recapture models can be easily fitted using ...

An 11-digit identification system for individual Nile crocodiles using natural markings
Koedoe: African Protected Area Conservation and Science, 2016 Research and conservation of wild crocodiles and husbandry of captive crocodiles requires the reliable identification of individuals. We present a method using the individual colour markings on the first 10 single-crest scutes on the tails of Nile ...

Towards the mother-of-all-models: customised construction of the mark-recapture likelihood function [PDF]
Animal Biodiversity and Conservation, 2004 With a proliferation of mark–recapture models and studies collecting mark–recapture data, software and analysis methods are being continually revised. We consider the construction of the likelihood for a general model that incorporates all the features ...

Isolation by distance in a population of a small land snail Trochoidea geyeri : evidence from direct and indirect methods [PDF]
, 2006 Population structure was estimated in a continuous population of a small land snail (Trochoidea geyeri). Mark-recapture experiments and randomly amplified polymorphic DNA analyses indicate that the population structure can be described by the isolation ...

An evaluation of population indices for northern bobwhite
Wildlife Society Bulletin, 2019 Northern bobwhite (Colinus virginianus) populations are monitored using 2 general approaches—population indices and abundance estimators. Due to their convenient sampling designs, indices are commonly used by land managers and researchers to predict or ...
