| Benthic chambers were used to investigate fluctuations in nutrient fluxes and oxygen changes when comparing two benthic biota. Muddy sediments located under mussel-cultivation ropes were compared with a station outside the mussels' influence. Biodeposition from the mussels results in a drastic increase in the nutrient fluxes. A standard procedure is established in order to give reliable comparisons between stations and seasons: as a rule it should include six-hour periods of incubation with sampling intervals of two hours and at least four benthic chambers - preferably six - at each station. |

| Two benthic tropical environments were sampled in two different ways, raising a methodological problem: the suitability of a given sampling plan for any ecological problem. On the Ivory Coast the sampling schedule consists of transects, stations being distributed in relation to hydroclimatical conditions. In Madagascar, because of the environmental complexity, stations were arranged geographically on a grid pattern. The analysis of results suggest that the character of informations which are introduced by means of the "stratifier" (sampling plan criterion) influences the character of the results. In the authors' cases, the results appear as a distribution in terms of hydroclimatical and sedimentological conditions on the Ivory Coast and in terms of... |
