Whither Fresh Waters and Their Biota?

Abstract

The subject of ‘Whither Freshwater Biota?’ implies a general and directional change in freshwater fauna and flora which is not wholly favourable and which might need checking. It also lends itself to a number of interpretations, although I prefer to consider it to refer to the effect of human activities not only on freshwater biota but also on the aquatic environments with which they are associated and which support them. It is accordingly relevant to examine these activities as causes and agents of change, and to consider the impact which they make in our particular context.
