Stemming from chemical, toxicological, and physiological studies begun in the latter part of the 19th century and applied widely in the first six decades of this century, microcosm technology has come to depend heavily on advanced analytical

Each of these is contingent on the ecosystem into which the chemical is introduced; therefore none can be resolved adequately without a perspective that considers the ecosystem and its interactions with the introduced chemicals. Yet, a

Given a solid understanding of ecosystem exposure-response-recovery relationships and their uncertainties, we might reasonably balance risks to

In the study of single species we seek to understand how toxic substances affect the physiological function of individuals, and how toxic substances might affect the demography of the population. In essence, we wish to predict whether
