An appealing, promising, and problematic function of ecology is its advanced­ ity, either conceptual and observational. expanding acknowledgment of the significance of scale testifies to the moving concentration in huge components of ecology. within the rush to discover difficulties of scale, one other normal point of ecolog­ ical platforms has been given much less consciousness. This point, both very important, is heterogeneity. Its significance lies within the ubiquity of heterogeneity as a characteristic of ecological structures and within the variety of questions it increases­ inquiries to which solutions should not on hand. what's heterogeneity? Does it vary from complexity? What dimensions desire be thought of to judge heterogeneity ade­ quately? Can heterogeneity be measured at a number of scales? Is heterogeneity aside of association of ecological structures? How does it swap in time and house? What are the reasons of heterogeneity and explanations of its swap? This quantity makes an attempt to respond to those questions. it really is dedicated to iden­ tification of the which means, diversity of purposes, difficulties, and methodol­ ogy linked to the learn of heterogeneity.
