Estimating population size of elusive animals with DNA from hunter-collected feces: four methods for brown bears

Abstract: Noninvasive genetic methods can be used to estimate animal abundances and offer several advantages over conventional methods. Few attempts have been made, however, to evaluate the accuracy and precision of the estimates. We compared four methods of estimating population size based on fecal...

Description
Summary:Abstract: Noninvasive genetic methods can be used to estimate animal abundances and offer several advantages over conventional methods. Few attempts have been made, however, to evaluate the accuracy and precision of the estimates. We compared four methods of estimating population size based on fecal sampling. Two methods used rarefaction indices and two were based on capture-mark-recapture (CMR) estimators Palabras Clave: análisis de heces, captura-marcaje-recaptura, estimaciones de tamaño poblacional, identificación individual, MARK, rarefacción, Suecia, Ursus arctos
