Non‐invasive genetic censusing and monitoring of primate populations

摘要: Knowing the density or abundance of primate populations is essential for their conservation management and contextualizing socio-demographic behavioral observations. When direct counts animals are not possible, genetic analysis non-invasive samples collected from wildlife allows estimates population size with higher accuracy precision than possible using indirect signs. Furthermore, in contrast to traditional survey methods, prolonged periodic sampling across months years enables inference group membership, movement, dynamics, some kin relationships. Data may also be used estimate sex ratios, differences dispersal distances, detect gene flow among locations. Recent advances capture-recapture models have further improved derived samples. Simulations these methods shown that confidence interval point includes true when assumptions met, therefore this range minima maxima should emphasized monitoring studies. Innovations such as use sniffer dogs anti-poaching patrols sample collection important ensure adequate sampling, expected development efficient cost-effective genotyping by sequencing DNAs will automate speed analyses.
