| 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... |

| The fish assemblages of two artificial reef systems of the south coast of Algarve (Portugal) are presented, and a comparative study is made of their species richness variation according to their location off the Ria Formosa lagoon. Each system consists of a protection reef and an exploitation reef. Gillnets, traps, longline and visual census were used as sampling techniques. Both reefs showed similar species richness, in each case higher than that of Ria Formosa. No significant differences of species richness were found between the reef systems (p = 0.1). However, the exploitation reefs showed a significant difference of species richness, that was more evident when accumulated species richness was used to compare them (p = 0.01). |
