Joint Analysis of Live and Dead Encounters of Marked Animals
نویسندگان
چکیده
Recently developed methods for analyzing mark–recapture data allow simultaneous modeling of information from a variety of animal encounters. Incorporating this extra information in an analysis requires use of a more complicated model but can lead to improved precision of estimates. An important aspect of such joint models is that movement of animals to and from the banding site can be incorporated. This allows relaxation of a restrictive assumption made about animal movement in the Cormack-Jolly-Seber model. We review the theory behind joint analysis of mark–recapture data and illustrate application of the models using data from mallard ducks (Anas platyrhynchos), paradise shelducks (Tadorna variegata), and common goldeneye ducks (Bucephala clangula).
