摘要: Abstract Use of genetic marks to identify individuals and generate population estimates using mark–recapture methodologies has become increasingly common. Recently, brown bear (Ursus arctos) have been made DNA isolated from hair follicles as the mark, obtaining with a barbed-wire enclosure around scent lure. While this method successfully used in low-density populations, it would be difficult use areas dense concentrations bears because high probability collecting multiple at single site during trap session. We designed evaluated single-catch snare collect late summer. hung snares, modeled after wolf (Canis lupus) neck snare, on trails along streams where congregated feed spawning salmon (Oncorhynchus spp.). During 2 years 1,000 snares were tripped 455 contained hair. determined genotypes 309 samples collected. ...
