This is the second model for the AMNH DecodeNYC course. Populations are now held stable for mice and deer, but infection with Lyme-causing spirochetes is tracked. Ticks have a digestion period between bites. Ticks reproduce after 3 feedings, but all bites are considered equivalent.
I edited this and added pesticides to some of the deer to test this approach to decreasing the cases of lyme disease.
