Capture-Recapture Methods

摘要: Capture–recapture methods have a long history of use, but most recently received greater attention from biologists and statisticians due to their frequent application. The Petersen method, in which single mark, release recapture is made, forms the basis for many more sophisticated that exist today. basic principle inherent capture–recapture given knowledge size marked subset population, one can estimate demographic information on larger population interest. Closed models do not allow migration or mortality natality. Open these processes thus are intensely parameterized. often require specific assumptions may prove be invalid. For example, some all animals assumed equal capture probabilities occasion. Thus, realistic with weaker being developed by incorporating multiple periods, sources recoveries, improved sampling designs, age spatial structure into modelling process. In addition, combinations other survey types enhanced technology, e.g. radio telemetry, allowed additional included estimating important parameters.
