Long-distance dispersal of a subadult male cougar from South Dakota to Connecticut documented with DNA evidence

摘要: We report the long-distance dispersal of a subadult male cougar ( Puma concolor ) from South Dakota to Milford, Connecticut, where it was struck and killed by vehicle. Genetic samples suggest this animal originated Black Hills while isotope analysis physical inspection revealed no evidence that had been held in captivity. detected dispersing individual at 5 locations along its route (Minnesota, 3 times Wisconsin New York) with DNA fecal or hair samples, multiple photographs citizen-run camera traps (3 1 Michigan). The > 2,450 km straight-line distance (Black Connecticut) traveled is longest documented for species. propose likely 2,700 over 2 years based on topography our confirmed records. excessive movement motivated absence female cougars route. documentation such rare biological event not only shows great potential but also highlights ability detect these movements verifiable voucher photographic Evidence collected one animal, complete data most anecdotal reports east, further confirms lack breeding population region.
