Anolis turnover

This cartoon was done for a friend who studies evolution in Anolis lizards.  The theme here is that as the climate warms in the tropics, habitat specialist species that rely on cool temperatures in the shade of the forest may be displaced by robust habitat generalist species that move into the increasingly warm shadows.  Anolis, as well as other types of lizards, have speciated by partitioning their diverse tropical environtment, and may be homogenized by climbing temperatures.  The friend for whom this cartoon was made also has a thing for tattoos, hence the ink on that bullisome lizard.
