My colleagues and I have examined these questions in several contexts. Our work suggested that bird diversity responds to loss of forest cover much less than the composition of bird assemblages. My colleagues and I do similar broad-scale work examining variability among aquatic systems. For example, it is well known that algal biomass depends strongly on nutrient availability. Recent theory suggests that predators should also strongly affect prey abundance.
Stocking makes no difference.
