Detection and persistence of environmental DNA from an invasive, terrestrial mammal.

摘要: Invasive Sus scrofa, a species commonly referred to as wild pig or feral swine, is destructive invasive with rapidly expanding distribution across the United States. We used artificial wallows and small waterers determine minimum amount of time needed for eDNA accumulate in water source detectable level. removed from tested detection over course 2 weeks understand persistence. show that our method sensitive enough detect very low quantities shed by terrestrial mammal has limited interaction water. Our experiments suggest number individuals shedding into system can affect persistence eDNA. Use an technique benefit management efforts providing finding even numbers may be elusive using other methods.
