| During the year 1980, monthly observations were made on the distribution and dynamics of fish populations in two mangrove lagoons (Belle-Plaine and Manche-a-Eau). A total of 39 species was found in the two mangrove lagoons but the maximum number observed did not exceed 19 species for each sampling. The species were separated into four main groups: (1) the sedentary species which spend their whole life in the mangrove lagoons; (2) the species only represented by juvenile individuals (the greatest group); (3) the species occurring occasionally in the mangrove lagoon; (4) the species only observed during the reproduction period. Three demographic models were tested: the models of Preston, Motomura and MacArthur. Preston better fitted the population of... |

| Fish communities from two lagoon ecosystems, Ria Formosa (Portugal) and Grand Cul-de-Sac Marin (Guadeloupe), show interesting similarities of spatial and temporal organization. On the temporal scale, three community changes are observed in both systems, corresponding to massive arrivals and/or departures of migratory species. However, these migrations are more conspicuous in the Ria Formosa than in the Grand Cul-de-Sac Marin. On a spatial scale, the community structure is also largely determined by migratory species, whose abundance is a factor of homogenization. This is clearly observed in Ria Formosa, where the lagoon selection applies on a regional scale. Conversely, the community of sedentary fish identifies remarkable stations affected by chronic... |
