“…One of most common management practices to reduce the sanitary degradation in Brazilian lagoons is the increase of water exchange with the sea by artificial sandbar openings (Suzuki et al 1998, Suzuki et al 2002, Ferreira & Freire 2009, Cezar et al 2015. However, sandbar openings have also resulted in ecological (Crippa et al 2013, Lanés et al 2015 and even sanitary degradation (Bozelli et al 2009, Lopes & Bozelli 2014 whose direct and indirect effects can be alleviated or exacerbated through interactive effects with dynamic environmental drivers. This study used long-term data from two Neotropical lacustrine freshwater systems (Batata Lake, an Amazonian floodplain lake and Imboassica lagoon, an Atlantic coastal lagoon by increasing salinity and reducing the water volume (Fernandes & Esteves 2003).…”

The present study investigated the intra-ecosystem variability of nutrient enrichment (nitrogen -N- and phosphorus -P-), density of faecal coliforms (i.e., as a proxy of sanitary conditions), and ecological responses of the zooplankton community structure in a tropical urban coastal lagoon, following eutrophication, changes in rainfall, and episodic sandbar openings. Surface waters were monthly taken over 14 years (1992-2005) within the long-term monitoring program ECOlagoas from two sampling stations at the Imboassica lagoon (Northern of the Rio de Janeiro State, Brazil): near a domestic wastewater channel (SEWAGE station), and at the limit to the sea (SANDBAR station). Changes in faecal coliforms and nutrient concentration reduced water quality due to untreated sewage inputs, which was intensified by artificial sandbar openings mainly under low rainfall, such as observed in February 2001. Indeed, a greater depth and subsequent volume of water of the Imboassica lagoon during the acidification period (i.e., attributed to the increased rainfall, and lower frequency of sandbar openings) contributed to dilute the faecal coliform only in the SANDBAR station. In turn, the zooplankton community structure showed that episodic sandbar openings promoted the loss of their functional features derived from a reduction and replacement of species over time, even in the period of lower frequency of sandbar opening and dilution of nutrient concentrations. Our findings indicate that sandbar openings are not the best management practice when facing coastal eutrophication, once it may cause harmful effects on sanitary conditions and ecological community related to zooplankton, mainly in periods of decline in rainfall.

“…The macrobenthos is a particularly important part of the biocenosis in coastal wetlands because these organisms play a key role in transferring energy and materials within the food web (Covich et al 2004;Dauvin et al, 2006). Due to its ecological importance, obvious presence, high sensitivity to disturbance, and direct contact with sediments, the macrobenthos of coastal ecosystems is widely used as a tool to detect the environmental impacts of pollution and other consequences of reclamation activity (Buschbaum et al, 2012;Li et al, 2016), and has therefore been used to support ecologically sustainable marine management (e.g., Borja et al, 2000;Naser, 2011;Crippa et al, 2013;Nishijima et al, 2015).…”

Human activities such as seashore reclamation can have profound negative impacts on the macrobenthos of coastal wetlands. Using the Yellow River Delta as a case study, we conducted a thorough search of the literature to create a synthesis about the effects of reclamation processes. We found 31 publications that met our selection criteria, and we summarized their data to systematically quantify the impacts of reclamation on the dominant species, biomass, abundance, and biodiversity indices. We found that the dominant species changed remarkably, from Mollusca in the 1980s to Polychaeta, Crustacea, and Insecta (indicating a transition from a marine to a terrestrial environment) after 2000. The number of macrobenthos species in the community decreased by more than half from the 1980s to the 2010s and the effect sizes in the 2000s and 2010s both differed significantly from 0 (p < 0.01; t-test). Both the biomass and the abundance of the macrobenthos decreased significantly in the 2000s (p < 0.05 and p < 0.01, respectively; t-test), but not in the 2010s. The Margalef, Shannon-Wiener, and Pielou biodiversity indices did not differ significantly among four periods (from 1985 to 2015) or among the various reclamation activities. The number of species and biomass have decreased significantly under the comprehensive influence of seashore reclamation activities. Under individual reclamation activities, the number of species and their biomass decreased slightly but not significantly. The results of this research improve our understanding of the relationships among reclamation activities and the resulting changes in the macrobenthos community, thereby improving our ability to sustainably use these wetlands. We have prepared a suggested list of criteria to help future seashore reclamation researchers increase the quantity and quality of the data available to support future meta-analyses.

“…The ichthyofauna along the saline gradient of the Lagoa do Peixe is represented by limnetic, marine and estuarinerelated species (Loebmann and Vieira, 2005); however, the richness, composition and temporal dynamics of the ichthyofauna in the floodplain ponds are unknown. Recent studies show that the artificial sandbar opening of Lagoa do Peixe influences plant, invertebrate and tadpole communities in the floodplain ponds (Crippa et al, 2013;Rolon et al, 2013;Moreira et al, 2014), knowledge of which is crucial for the management of natural resources in the Lagoa do Peixe National Park, a unique Ramsar wetlands site of international importance in southern Brazil.…”

Summary Two hypotheses were tested: that the artificial sandbar opening decreases the richness, diversity and abundance of fishes and alters the fish composition in floodplain ponds; that the salinity variations influence fish richness, diversity, abundance, as well as composition. Results suggest that artificial sandbar openings did not reduce the richness or diversity of freshwater fishes in southern Brazil floodplain ponds. Nevertheless, this process causes an increase in salinity, which determines significant differences in species composition between natural and managed areas. In this sense, the artificial sandbar opening must be considered with caution, since the area of study is one of the most important conservation units in wetland systems of southern Brazil.
