Opportunity for selection in southern elephant seals ( Mirounga leonina): the effect of spatial scale of analysis
Abstract The opportunity for selection, I , calculated as the variance in relative fitness, sets an upper limit to the amount of adaptive change that selection may produce. Therefore, it is a potentially valuable, and frequently used, measure of the potential of action of phenotypic selection. Altho...
