Recent models for mark-recapture and mark-resighting data.

摘要: A topic of current interest in the analysis capture-recapture data is development models that allow biologically meaningful constraints on survival and capture rates. Of particular are which a function environmental variables. Thus, an important recent paper, Clobert Lebreton (1985) described from resighting marked birds, where was modelled as winter temperature. have, however, developed their methodology (including necessary computer routines) context samples only (thus assuming no losses capture), whereas with appropriate interpretation formulae methods can be applied to recapture frequently include capture. The purpose this note indicate modifications needed make Clobert-Lebreton applicable data. Also, prevent future duplication effort, relationships between have been separately for noted. Procedures et al. based model estimating time-specific sighting rates data, proposed by Cormack (1964). year after Cormack's appeared, Jolly (1965) Seber what now called Jolly-Seber (and population size) allowing possibility physical may result loss some animals. With view achieving parsimony improving estimator precision, parallel efforts since specialized original cases and/or (resighting) assumed constant. Sandland Kirkwood (1981) describe reduced-parameter versions (1964) model, (1982) Brownie, Hines, Nichols (1986) analogous model. corresponding programs, program (Clobert al., 1985; Lebreton, 1985) permits greatest flexibility modelling [For other somewhat efforts, not immediately relevant discussion here, see e.g., Crosbie Manly (1985).] differ new releases viewed uninformative constants former, random variables (providing information about latter. yield equivalent obtaining estimates rates, but lead different interpretations expectations variance (Seber, 1982; Brownie 1986). When there capture, fact produce identical point interval 1982, pp. 214-215; Robson, 1983). Reduced-parameter models, same assumptions should numerically
