The NATO Advanced Research Workshop on "Behavioural Adaptation to
Intertidal Life" held in Castiglioncello, Italy (May, 1987) was attended
by 50 participants, most of whom presented requested lectures. It was
perhaps the first time that specialists of various animal groups, from
cnidarians to birds, were able to meet and discuss the importance of
behavioural adaptation to this peculiar, sometimes very harsh
environment. But the taxonomic barrier is not the only one which the
meeting attemped to over- come. Lately, the research on intertidal
biology has spread from pure taxonomy and static analysis of community
structure to such dynamic aspects as intra- and interspecific
relationships, and physiological mechanisms aimed at avoiding stress and
exploitation of limited-resources. This increasing interest stems not
only from an inclination for this particular ecological system and some
of its typical inhabitants, but also from the realization that rocky and
sandy shore communities are suitable models for testing and improving
some global theories of evolutionary biology, behavioural ecology and
sociobiology. The number of eco-physiological and eco-ethological
problems emerging from the study of intertidal animals is fascinatingly
large and a complete understanding of this environment cannot be reached
using a strictly "reductionistic" or a pure "holistic" approach.
