Parasites play a role in mediating invasion success by affecting host fitness and altering interactions between resident and invasive species. The brown anole (Anolis sagrei) is a highly invasive lizard native to the Caribbean that has spread into the southeastern United States, causing displacement and habitat shifts in its native congener, the green anole (Anolis carolinensis), where their ranges overlap.
The brown anole (Anolis sagrei)
We will examine whether co-occurring green and brown anoles are differentially parasitized, and if so, whether these differences correlate with variation in genes linked to parasite resistance. This study will help us gain a better understanding of how parasitism can influence range expansion in invasive species.
