“…The calculation of total carbon accumulation (g TC m −2 year −1 ) in the top 10 cm of the soil core was determined by multiplying the carbon density (g C cm −3 ) by the accretion rate (cm year −1 ) following Bernal and Mitsch (2008; and Bianchi et al (2013).…”

Salinity alterations will likely change the plant and environmental characteristics in coastal marshes thereby influencing soil carbon accumulation rates. Coastal Louisiana marshes have been historically classified as fresh, intermediate, brackish, or saline based on resident plant community and position along a salinity gradient. Short-term total carbon accumulation rates were assessed by collecting 10-cm deep soil cores at 24 sites located in marshes spanning the salinity gradient. Bulk density, total carbon content, and the short-term accretion rates obtained with feldspar horizon markers were measured to determine total carbon accumulation rates. Despite some significant differences in soil properties among marsh types, the mean total carbon accumulation rates among marsh types were not significantly different (mean ± std. err. of 190 ± 27 g TC m −2 year −1 ). However, regression analysis indicated that mean annual surface salinity had a significant negative relationship with total carbon accumulation rates. Based on both analyses, the coastal Louisiana total marsh area (1,433,700 ha) accumulates about 2.7 to 3.3 Tg C year −1 .Changing salinities due to increasing relative sea level or resulting from restoration activities may alter carbon accumulation rates in the short term and significantly influence the global carbon cycle.

“…This is because mangrove forests have some of the highest average C storage per land area in unmanaged terrestrial ecosystems (Doughty et al 2015, Kelleway et al 2015. As mangroves replace salt marsh vegetation, soil C may increase (Bianchi et al 2013). However, such invasions significantly change habitat structure and we know little about impacts on biotic interactions, potential lags for co-evolved species to shift, or challenges to mosquito control management (Dale et al 2013).…”

“…Despite these challenges, some freshwater wetlands may be relatively resilient to climate change (Baron et al 2002;Middleton and Souter 2016) within certain boundaries of temperature, precipitation, water level, salinity intrusion, and storm activity Bernstein et al 2007). At the same time, salinity intrusion poses specific threats to coastal freshwater wetlands because many species in these ecosystems are intolerant of salinity (Keddy 2010).…”

Part 1 of this review synthesizes recent research on status and climate vulnerability of freshwater and saltwater wetlands, and their contribution to addressing climate change (carbon cycle, adaptation, resilience). Peatlands and vegetated coastal wetlands are among the most carbon rich sinks on the planet sequestering approximately as much carbon as do global forest ecosystems. Estimates of the consequences of rising temperature on current wetland carbon storage and future carbon sequestration potential are summarized. We also demonstrate the need to prevent drying of wetlands and thawing of permafrost by disturbances and rising temperatures to protect wetland carbon stores and climate adaptation/resiliency ecosystem services. Preventing further wetland loss is found to be important in limiting future emissions to meet climate goals, but is seldom considered. In Part 2, the paper explores the policy and management realm from international to national, subnational and local levels to identify strategies and policies reflecting an integrated understanding of both wetland and climate change science. Specific recommendations are made to capture synergies between wetlands and carbon cycle management, adaptation and resiliency to further enable researchers, policy makers and practitioners to protect wetland carbon and climate adaptation/resiliency ecosystem services.

“…Áreas úmidas na região tropical são reconhecidamente importantes estocadoras de carbono (BERNAL; MITSCH, 2008;BIANCHI et al, 2013;DE LA CRUZ, 1986;NEUE et al, 1997). Apesar de ainda pouco exploradas no Bioma Cerrado, os resultados obtidos neste artigo confirmam o papel desempenhado por essafitofisionomia para a manutenção docarbono orgânico no solo.…”

We selected 4 regions of the Federal District with this kind of vegetation formation, characterized by low anthropic impact. In each one of the sampled regions, we marked a transect with 4 equidistant points and collected material at 7 different levels of depth: 0-5, 5-10, 10-20, 20-30, 30-40, 40-50 and 50-60 cm. We determined the texture, bulk density and concentration of carbon at each depth. The average carbon storage for Humid
