Prions, which cause chronic wasting disease and other transmissible spongiform encephalopathies in ungulates, can remain active in soils for years. The reproductive age of ungulate populations is well within the residence time of prions in the soil. Reproduction and mortality in disease-free wildlife populations is regulated by density-dependent mechanisms, which also underlie the concept of carrying capacity. Here, we present a model of a susceptible deer population with density-dependent… CONTINUE READING
