Citation Context ...ng data are spatially representative, and measures of biodiversity should be constructed so that they are not biased when detectability of species within survey plots is imperfect. Distance sampling (=-=Buckland et al., 2001-=-, 2004) is ideally suited for monitoring a number of species. It provides a rigorous framework for survey design (Buckland et al., 2001:228-323; Strindberg et al., 2004), and explicitly models detecta... |

This heterogeneity can be modelled over all distances (=-=Laake and Borchers, 2004-=-), or we can assume ‘point independence’ (Laake, 1999; Laake and Borchers, 2004), or both (Borchers et al., 2006).

Monte Carlo confidence intervals

(Show Context)
Citation Context .... A simple but robust method of estimating confidence limits is to order the bootstrap estimates of the parameter, and extract the appropriate percentiles from the ordered list as approximate limits (=-=Buckland, 1984-=-). If bootstrap resamples are constrained so that each resample has the correct number of edge squares of each type (see Fig. 3), then total effort will not vary across resamples. However, this strate... |

However, for a single realization of the design, especially if the number of strips sampled is small or if the objects’ spatial pattern is markedly aggregated, it may prove beneficial to ... |
