Genetic mark-recapture population estimation in black bears and issues of scale

摘要: ABSTRACT Abundance estimates for black bears (Ursus americanus) are important effective management. Recently, DNA technology has resulted in widespread use of noninvasive, genetic capture—mark—recapture (CMR) approaches to estimate populations. Few studies have compared the CMR methods other estimation methods. We used bear population at 2 study sites northern New Hampshire (Pittsburg and Milan) consecutive years. these those derived from traditional by Fish Game Department (NHFG) using hunter harvest mortality data. Density produced with were similar both years comparable In 2006, estimated number Pittsburg was 79 (95% CI = 60–98) corresponding a density 15–24 CI) bears/ 100 km2; 2007 83 67–99; 16–24 bears/100 km2). of...
