Question

and contrast the terms dispersion and dispersal. 4.What is an ideal free distribution and under what conditions can it be established? 5. Southern European songbird, the blue tit, breeds in two habitats that differ greatly in quality. In deciduous oak forests, blue tits produce so many young that their populations have the potential ofgrowing at the astronomical rate of 10% annually.
