Dissolved organic molecule coming either from the degradation of dead organisms or from the excreta of living organisms (plankton).

Amphibious wooded area mainly consisting of mangrove trees found in muddy sediments of tropical coastlines.

Coefficient reflecting the degree of diversity of a community. The expression of the diversity index is based on two parameters: the number of species and number of individuals per species. There are many indexes but the most commonly used is that of Shannon and Weaver (1949). It expresses the relative importance of the number of abundant species in a given environment. Thus, the greater the proportion of rare species and that of abundant species smaller, the greater the diversity

Summarizes the numbers of a species in a population found in all samples collected in this population.

All planktonic organisms consisting of fish eggs and larvae.
