Simple mark-recapturewe assume we know it, and with distance sampling methods (Chapter 7) we assume “capture” is certain on the line or point. Depending on the application, these assumptions may be quite reasonable; when they are not, removal or mark-recapture methods can be useful. With mark-recapture methods, animals

Distance samplingection probability. Distance sampling comprises several related methods which involve measuring or estimating distances of detected animals from a line or point. The two main methods are line transect sampling and point transect sampling (sometimes called variable circular plots). Both are extension

Further building blocksed in the process determining the population state (the spatial distribution of animals, for example), this would be a reason to use model-based methods. Model-based methods can also lead to substantial improvement in precision, because some of the variation in density is “explained” by the model in

Dynamic and open population modelserage of integrated modelling for open populations requires a book in its own right. Second, the tools to fit such integrated models have only recently been developed, and more research is needed to explore their potential.
