| specimen-based modeling, stopping rules, and the extinction of the ivory-billed woodpecker. | assessing species survival status is an essential component of conservation programs. we devised a new statistical method for estimating the probability of species persistence from the temporal sequence of collection dates of museum specimens. to complement this approach, we developed quantitative stopping rules for terminating the search for missing or allegedly extinct species. these stopping rules are based on survey data for counts of co-occurring species that are encountered in the search f ... | 2012 | 21797923 |
