A key prediction made by theories of density‐dependent competition is that resource overlap should increase the intensity of competition. By extension, we can predict that competition should lead to density‐dependent natural selection. I studied natural selection on limb length and body size in a total of seven populations of Anolis sagrei over 3 years in the Bahamas. Experimental manipulations of population density on small off‐shore cays revealed that the strength of natural selection on body… Expand
