This text contains the papers of a meeting on American isopods, the only crustacean group with representatives in all terrestrial ecosystems. It deals with two main subjects: the effects of stressful conditions on the individual animal; and distribution and selection of microhabitat.

This work provides a guide to current research in barnacle evolution. Topics covered include: chemical signals in barnacles; larval settlement; naupliar evidence for cirripede taxonomy and phylogeny; and South American patterns of barnacle distribution.
