Andrew S. Norton, Duane R. Diefenbach, Christopher S. Rosenberry, Bret D. Wallingford
2013, Journal of Wildlife Management (77) 606-615
Although monitoring population trends is an essential component of game species management, wildlife managers rarely have complete counts of abundance. Often, they rely on population models to monitor population trends. As imperfect representations of real-world populations, models must be rigorously evaluated to be applied appropriately. Previous research has evaluated population...
