“…With the oxygenation of water near the sediment, aerobic conditions prevail that enable the survival of several taxa, independently of the depth and amount of organic matter in the sediment. In some coastal lagoons of Rio Grande do Sul algae of the genera Chara and Nitella have been found at depths of up to 10 m, where the low turbidity allows the penetration of light (Schäfer 1992, Albertoni et al, 2001). The permanent movement of the water column also causes the phytoplankton to reach greater depths (Schäfer et al, 2009), enabling the existence of filter feeding organisms such as Corbiculidae (Table 1).…”

Benthic macroinvertebrates are widely used in evaluations of environmental impact and recommended in biomonitoring, but little used in Brazilian lentic environments. One of the main objectives has been to explain and predict the distribution of those species according to environmental characteristics. Thus, the study aims to characterize the predominant fauna of the Lake Figueira sediment and its relationship with organic matter and depth, analyzing seasonal variation in communities and aiming to select bioindicators of the trophic state. Sampling was carried out from January 2008 to January 2009, along the lagoon fetch, with an Ekmann-Birge dredge (area 225 cm²). Taxon richness was not significantly related with depth and organic matter content, but those variables were highly correlated (r = 0.962; r² = 0.926 and p < 0.001). The constant oxygenation of the whole water column allows the occurrence of organisms, independent of depth and organic matter content. Chironomidae was the most abundant taxon and from the frequency of occurrence, abundance and clustering analysis it was possible to select Larsia sp. , Goeldichironomus maculatus, Xenochironomus sp. , Aedokritus sp. Cladopelma forcipis, Cryptochironomus brasiliensis, Nilothauma sp.1 and Caladomyia sp. C, Tanytarsus sp. , Tanytarsus rhabdomantis and Chironomus gr. salinarius as potential indicators related with the spatiotemporal faunal distribution of Lake Figueira.

“…Differences in the species composition are accompanied by differences in diet and feeding modes. The most abundant organism on tidal flats (Polychaeta) are mainly consumers of detritus, while most organisms on salt marshes (Gastropoda) consume primarily periphyton (Albertoni et al 2001).…”

Salt marshes are regarded as among the most productive coastal ecosystems, important “blue carbon” sinks and a support for benthic communities with large abundances, whose structure may be strongly influenced by salt marsh vegetation. During the last few decades, Spartina alterniflora has been colonizing bare mudflats in the Bahía Blanca estuary, and a large increase in the area covered by salt marshes has been reported. This colonization can strongly influence the structure of benthic fauna and its role in the carbon cycle. The hypothesis of this study was that the community structure and the organic carbon contained in the meio- and macrobenthos change between tidal flats and salt marshes recently colonized by S. alterniflora. Response variables studied to compare the tidal flat and salt marsh were density, biomass and production to biomass (P/B) ratio of macro- and meiobenthos. Density and biomass of Gastropoda and P/B ratio of Nematoda were higher on the salt marsh than on the tidal flat. By contrast, density and biomass of Polychaeta were higher on the tidal flat. These results suggest that the expansion of S. alterniflora marshes on tidal flats produces changes in the structure of the macro- and meiobenthos community (taxonomic composition and biomass) that have an influence on carbon cycling.

“…Depending on their origin, trace elements exist in different mineral forms and chemical compounds in different combinations with mineral and organic components of soil and sediments which may vary according to various conditions (Calmano et al, 2001) Typha domingensis which is the species that is widespread in Bauchi is considered to be among the first wetland plants to colonize areas of newly exposed wet mud, with its abundant wind dispersed seeds. It survives in the soil for a long period with buried seeds (Albertoni et al, 2005). It also germinates best in sunlight and fluctuating temperature which is typical of many wetlands that regenerates on mud lands.…”
