| In order better to understand brackish ecosystem functioning, this study deals with zooplankton spatial organization in a North-Mediterranean lagoon (etang de Thau). A statistical treatment - spatial contiguity constrained clustering - is used to divide the lagoon into several homogeneous zones with regard to zooplankton communities. Confrontation between biological and physical patterns (hydroclimatic context data together with results of a numerical simulation of hydrodynamic circulation in the lagoon) tends to show that: 1) Zooplankton community spatial patterns have a short-term significance (few days) and do not reveal any seasonal characteristic; 2) Inversion of the water flows between the lagoon and the sea plays a major role in structuring and... |

| The analysis of the community structures of a Danish fjord macrofauna and of various Mediterranean lagoons results in the same interpretation of the organization of communities which start from meroplankton, leading to the formation of disorganized communities. The biotic and abiotic lagoon environment puts these populations under stress, causing gradual organization into structured one-species communities. Such an interpretation suggests that the degree of organization is measured by the species diversity or more precisely by one species alone. Each population has to develop and adapt strategy which favors migratory behavior. When this is not possible, a waste economy develops where the speed of the generation cycles corrects the catastrophic losses... |
