The need for a volume dealing with the concept of indicator
organisms became evident during a symposium on the subject,
organized by the present editors for the Southern California
Academy of Sciences. Ques tions were posed about the appropriate
uses of indicator organisms and the "rules" governing the
application of the indicator concept to particular problems. For
example, how does one distinguish true indicators from biological
anomalies? What kinds of organisms can appropriately be associated
with conditions and events at various scales in time and space? To
what extent does one species represent other species in the same
environmental setting? Can the indicator concept be applied to the
context of modern sampling and analytical technology? How can
anthropogenic perturbations be distinguished from natural
phenomena? How can unlike matrices from differing data bases with
differing scales best be matched? Such questions are especially
pertinent in today's research environment. The use of indicator
organisms, while certainly not new, is the corner stone for much
scientific research. In the past two decades, indicator organisms
have played increasingly important roles in the development and
implementation of public policy. In particular, indicator organisms
are being used to describe local environments and natural or
anthropogenic perturbations to them, although there are pitfalls
and problems associated with those usages. A growing number of
nonbiologists, including physical oceanographers, find indicator
organisms helpful, and sometimes essential, to their re search."
