Advances in Human Ecology : JAI Press Inc. : 9780762302574 : 22 Sep 1997 : This is the sixth volume in a series designed to publish theoretical, empirical and review papers on scientific human ecology. Human ecology is interpreted to include structural and functional changes in human social organization and sociocultural systems as these changes may be affected by, interdependent with, or identical to changes in ecosystemic, evolutionary or ethological processes, factors or mechanisms. Three degrees of scope are included in this interpretation: the adaptation of sociocultural forces to bioecological forces; the interactions, two-way adaptations, between sociocultural and bioecological forces; and the integration, or unified interactions, of sociocultural with bioecological forces.
