Reliability of noninvasive genetic census of otters compared to field censuses

Conservation and management actions are often highly dependent on accurate estimations of population sizes. However, these estimates are difficult to obtain for elusive and rare species. We compared two census methods for Eurasian otter: snow tracking and noninvasive genetic census based on the genotyping of faecal samples. With the noninvasive genetic census we detected the presence of almost twice as many otters as with snow tracking (23 and 10-15, respectively), and mark-recapture estimates based on the genetic census indicated that the real number of otters could be even higher. Our results indicate that snow tracking tends to underestimate the number of individuals and also that it is more susceptible to subjective assessment. We compared the strengths and weaknesses of the two methods.

“…The wolverine was haplotype "A" (Wilson et al 2000), a genetic group that occurs throughout the Rocky Mountains, Alaska, and Canada (USFS 2008). A gender test (Hedmark et al 2004) revealed that the animal was a male. Thus, although researchers were able to determine that the animal was not a native California wolverine, its exact origins and means of arrival in California remain unknown.…”

“…The technique involves the extraction of DNA from materials like faeces, shed hair, feathers, urine and sloughed skin (Höss et al 1992; Kohn and Wayne 1997;Goossens et al 1998;Segelbacher 2002;Fernando et al 2003). The methodology has been increasingly applied to a wide variety of species (Taberlet et al 1997;Reed et al 1997;Kohn et al 1999;Ernest et al 2000;Garnier et al 2001;Eggert et al 2003;Goossens et al 2003;Hedmark et al 2004;Vidya and Sukumar 2005;Smith et al 2006;Bhagavatula and Singh 2006). Studies on the genetic diversity of tigers have focused on mitochondrial DNA (Zhang et al 2006a), and microsatellites (Zhang et al 2006b;Xu et al 2005;Williamson et al 2002).…”
