‘Video-scats’: combining camera trapping and non-invasive genotyping to assess individual identity and hybrid status in gray wolf

摘要: Motion-activated video cameras and non-invasive genetic sampling are tools commonly used to obtain relevant information on wild populations of rare or elusive carnivores while minimizing disturbance. The two approaches usually implemented separately, but they occasionally integrated at a population level, mostly in order estimate size. Here we show the advantages combining camera trapping genotyping an individual monitored Italian wolf affected by introgression from domestic dogs. After 24 defecation events recorded traps located marking sites, samples (‘video-scats’) were collected determine individuals' identity based analysis sex markers, 11 autosomal microsatellites, Y-chromosome microsatellites control region mitochondrial DNA. Genetic data for 19 successfully genotyped scat combined with morphological behavioural traits observed videos compared ...
