In this age of elevated primary and utilized learn on biodiversity, no unmarried quantity was once as but dedicated to a few of the temporal and spatial elements of aquatic biodiversity. the current booklet is released in honour of Professor Henri Dumont (Ghent, Belgium) on the party of his retirement as Editor-in-Chief of Hydrobiologia. the amount offers a range of contributions on aquatic biodiversity, written by means of colleagues from the editorial board, fellow editors of aquatic journals and previous scholars and collaborators. Contributions take care of a large spectrum of subject matters regarding aquatic biodiversity and canopy fields equivalent to real- and palaeolimnology, taxonomy, and basic and utilized limnology. Even reconnaissance chapters on administration and cultural effect of water our bodies are integrated. The booklet combines state of the art contributions in aquatic sciences.

Example text

The public and decision makers were informed through popular books such as the 'Si lent Spring' from Rachel Carson (1964) about the consequences of large-scale use of DDT and other insecticides. The so-called DDT "syndrom" (Provost, 1972) had positive consequences for biodiversity: it limited the use of pesticides and stimulated impact and environmental hazard assessments. It also re-inforced the regulation about the use of pesticides. , in press). g. g. , 1987). In 1974, the OCP, a 20-years onchocerciasis control campaign, was initiated at the request of seven West African countries .

The biomonitoring approach designed to evaluate the environmental effects of ocr activities was also the first, longest, and largest scale biomonitoring programme ever conducted in the tropics. Throughout the programme, the selection of insect- icides that were efficient against the vector but not too toxic for the non-target fauna was a permanent concern of OCP-biologists . In this review article, we describe the role biodiversity has played in OCP, and how our understanding of the ecology of West African freshwaters (mainly rivers) was improved through research conducted during OCP.

The vector control operations consisted of using insecticides to treat the breeding sites of rivers where larval stages of the S. damnos um complex develop. The great advantage of larviciding was that it attacked the vector at a stage where it is concentrated in a very small area (fast flowing parts of rapids in large rivers). In comparison, the adult black fly population cannot be controlled because of their dispersal and the wide variety of their resting places. The development of the aquatic stage from egg to pupae is around one week; hence, insecticides were applied weekly.
