Abstract: Understanding the changes in abundance for wildlife populations across
time is critical to developing appropriate conservation strategies. These
changes may be due to environmental or biotic variables. To accommodate
seasonal effects that change from year to year into models for the size of
an open population we consider a time-varying coefficient model. We fit
this model to capture--recapture data using Jolly--Seber type estimators
and nonparametric P-spline techniques. The model is applied to a
capture--recapture data set collected on the Little Penguin
$$Eudyptula$$ $$minor$$ over a 25 year period. In this presentation I will
discuss these models and the analysis of the Little Penguin data.
