Capture—recapture of white-tailed deer using DNA from fecal pellet groups

摘要: Traditional methods for estimating white-tailed deer population size and density are affected by behavioral biases, poor detection in densely forested areas, invalid techniques effective trapping area. We evaluated a noninvasive method of capture—recapture Odocoileus virginianus estimation using DNA extracted from fecal pellets as an individual marker gender determination, coupled with spatial function to estimate (spatially explicit capture—recapture, SECR). collected pellet groups 11 22 January 2010 at randomly selected sites within 1-km2 area located on Arnold Air Force Base Coffee Franklin counties, Tennessee. searched 703 10-m radius plots 352 pellet-group samples 197 over five two-day sampling intervals. Using only the freshest we recorded 140 captures 33 different animals (15M:18F). Male female densities were 1.9 (SE = 0.8) 3.8 1.3) km-2, or to...
