“…This may directly or indirectly enhance food availability to the shrimps in younger stands. Indeed, Morrisey et al (2003) showed that numbers of faunal taxa were higher in younger stands, and numbers of individuals of several taxa were also higher at these sites.…”

Mangrove swamps are key ecosystems along the Vietnam coast. Although mangrove litter is thought to represent an important input of organic matter and nutrients to the coastal aquatic systems, the factors determining the quality and size of this litter flux have not been studied so far. We monitored leaf, stipule, twig, and reproductive litter monthly in monocultures of Rhizophora apiculata mangrove forests of 7, 11, 17 and 24 years old in the Camau province, Mekong Delta, Vietnam. Litter traps were used to measure litter fall production from June 2001 till May 2002. Total litter fall was in the range of 8.86-14.16 t DW ha À1 year À1 . Leaves were the main component, and represented 70% of litter fall production in all stands. Total litter fall was lower in the older stands but the amount of reproductive litter was significantly higher in these stands (17 and 24 years). Biomass of leaf litter was highest between the end of the wet season and the beginning of the dry season. Phosphorus and nitrogen levels in leaf litter were significantly higher in younger than in older stands. Overall, our study indicated that young stands produced the highest input of litter and particularly of nitrogen and phosphorus to the surrounding aquatic system. Consequently, these stands contribute significantly to the fisheries.

“…This rich biodiversity and the ecological importance of estuarian ecosystems are favoured by their proximity with the sea that furnishes marine species through tidal inundations and mangroves trees (Zabi and Le Loeuf, 1993;Akin et al, 2003;Alfaro, 2006;Leonardo and Bemvenuti, 2006;Lee, 2008). Mangroves and seagrass habitats in estuarine systems provide more structures for potential invertebrates to settle on (Davis et al, 2001;Morrisey et al, 2002;Ellis et al, 2004;Alfaro, 2006).…”

The macroinvertebrate, assemblage investigated were collected in eight seasonal samplings from July 2007 through June 2009. A total of 4,179 individual macroinvertebrates were gathered, comprising 182 taxa belonging to 25 orders and 114 families. The most predominant groups were Molluscs and Crustacean which make up 71.11% of the taxonomic richness observed. Annelids and Insects were the second most predominant. This restricted biodiversity is based on a limited number of species such as Tympanotonus fuscatus radula, Pachymelania aurita, Neritina glabrata, Corbula sp., Clibanarius spp., Grandidierella africana, Nereis sp. and Chironomus sp.. Site typology based on environmental parameters reveals five assemblages in which no significant difference exists. The community is controlled by a salinity gradient but is also probably affected by hydrologic factors and human economic activities.

“…However, coastal ecosystems often form a mosaic of interlinked habitats that should not be considered in isolation. Each habitat has its own characteristics and hosts particular benthic assemblages [3]- [5]. Nevertheless, coastal habitats are threatened by anthropogenic stressors, including coastal development and habitat degradation [6]- [9].…”

The present study analyses the spatio-temporal variability of the macrozoobenthos from the intertidal zone of the Kneiss Islands (Gulf of Gabès, Tunisia). Samples were collected once from 34 stations, while seasonal variations were studied by sampling four times at 12 stations over the period 2013-2014. A total of 159 macrobenthos taxa associated with intertidal Zostera noltei beds are identified from the 34 stations, with a taxonomic dominance of crustaceans (32%), molluscs (29%) and annelids (27%). Abundance varies from 9244 to 36,844 ind·m −2 with a mean value of 14,346 ind·m −2 . Analysis of the trophic structure shows that the majority of stations are strongly represented by carnivores (41%), followed by the non-selective deposit feeders (16%). Cluster analysis and multidimensional scaling allow identification of three main benthic assemblages based on species abundance, corresponding to different sediment types and organic matter contents. The seasonal variability in abundance, diversity and community structure is mainly due to spring and summer recruitment. The biotic indices (i.e. AMBI, BO2A and BENTIX) show that the intertidal area of Kneiss Islands exhibits a good ecological status.
