Popular recent theory contends that the traits of species are "neutral" or unimportant to coexistence, yet abundant experimental evidence suggests that multiple species are able to coexist on the same limiting resource precisely because they differ in key traits, such as body size, diet, and resource demand. This book presents a new theory of coexistence that incorporates two important aspects of biodiversity in nature--scale and spatial variation in the supply of limiting resources. Introducing an innovative model that uses fractal geometry to describe the complex physical structure of nature, Mark Ritchie shows how species traits, particularly body size, lead to spatial patterns of resource use that allow species to coexist. He explains how this criterion for coexistence can be converted into a "rule" for how many species can be "packed" into an environment given the supply of resources and their spatial variability. He then demonstrates how this rule can be used to predict a range of patterns in ecological communities, such as body-size distributions, species-abundance distributions, and species-area relations. Ritchie illustrates how the predictions closely match data from many real communities, including those of mammalian herbivores, grasshoppers, dung beetles, and birds. This book offers a compelling alternative to "neutral" theory in community ecology, one that helps us better understand patterns of biodiversity across the Earth. 410 0$aMonographs in population biology. 606 $aEcological heterogeneity 606 $aBiodiversity 606 $aBiotic communities 606 $aAnimal population density 615 0$aEcological heterogeneity. 615 0$aBiodiversity. 615 0$aBiotic communities. 615 0$aAnimal population density. 676 $a577 686 $aWI 2100$2rvk 700 $aRitchie$b Mark E.$f1960-$01649331 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910821065103321 996 $aScale, heterogeneity, and the structure and diversity of ecological communities$93998018 997 $aUNINA
