If the invasive tropical species go dormant during cold weather, they certainly become easier prey. I wonder at what temperatures they are killed outright?
Not sure, I’m always amazed at the range of the Alligator, N. Carolina, Arkansas, Oklahoma, Texas, it does get cold.
I don’t know at what temp they go belly up, but you certainly do see more big snakes during the winter. When the sun comes up and heats up the sandy paths or dirt roads, the snakes will stretch out to warm up and catch some rays. Makes them obvious to spot, and they’re awfully sluggish.
