With each other In addition they present that comparable analyses can advise research at distinct scales of environmental heterogeneity, from ecological option of habitat to behavioral choice of eating plan. Issues of scale were being before long framed in express spatial types, specially by Levin 1992, who credits the robust impact of MacArthur.
