BTW, I was just browsing JSTOR and saw this:
Life history, habitat saturation and the evolution of fecundity and survival altruism. S. Lion and S. Gandon, Evolution, v. 64 n. 6 (2010), pp. 1594-1606. If you would like to, I could relate the substance (it is a tiny bit inconvenient for me to do right now, or I would have.)
