A hump‐shaped density–area relationship for island lizards

We evaluated the density of Anolis lizards as a function of island area, habitat diversity, and topographic diversity on the Grenadines islands. We found a hump‐shaped density–area relationship. Density at sea level increased with island area until an island was sufficiently large to contain multiple habitat types. Beyond this area threshold, average sea level density declined with island area. Increased species interactions on larger islands may explain the density decline.
