“…The annual emissions of CO 2 found in this study are in line with those previously reported for floodplain wetlands (10.91 ± 0.54 Mg CO 2 -C ha −1 yr −1 ) (Batson et al, 2015), coastal plain wetlands (11.29 Mg CO 2 -C ha −1 yr −1 ) (Morse et al, 2012) and occasionally (9.7 Mg CO 2 -C ha −1 yr −1 ) or frequently flooded (13 Mg CO 2 -C ha −1 yr −1 ) riparian forests (Jacinthe, 2015). Our results are also in part agreement with other investigations on comparable ecosystems that examined the impact of flooding on GHGs (Morse et al, 2012;Jacinthe, 2015;Kim et al, 2015;Marín-Muñiz et al, 2015). Jacinthe (2015) reported that CO 2 fluxes during summer were larger from a riparian forest affected by floods in winter and spring than from a flood protected area.…”

“…Peak CO 2 fluxes (above 75 mg CO 2 -C m −2 h −2 ) were recorded during periods B and D when water depths less than 9 cm were coupled with soil temperatures above 11 • C. No major variations in CO 2 fluxes were observed when water depths exceeded 12 cm. Other studies have shown a significant relationship between N 2 O fluxes and water depth in riparian woodlands (Mander et al, 2015;Marín-Muñiz et al, 2015), but no such correlation was found in this study (Sect. 3.4).…”

“…3.4) for both sites, suggests soil redox potential had minimal influence on the emissions of either gas. This contrasts with the finding of Marín-Muñiz et al (2015), who identified redox potential and water level as the main factors controlling GHG emissions in coastal freshwater wetlands. The redox potential of the two sites was different and the highest CO 2 emissions occurred at 220-362 and 145-259 mv at the SFS and LFS, respectively.…”

“…Similarly, many previous studies have reported higher N 2 O emissions in flood-affected wetlands across a wide range of redox potentials (−100 to 430 mv) (Yu et al, 2001;Wlodarczyk et al, 2003;Morse et al, 2012). Marín-Muñiz et al (2015) found an optimum range of 100-360 mv for the reduction of nitrate to N 2 O from a coastal wetland, whereas Morse et al (2012) reported values of 89 and 5.3 mv from rarely and intermittently flooded areas, respectively, as the conditions conducive for N 2 O production.…”

Abstract. Given their increasing trend in Europe, an understanding of the role that flooding events play in carbon (C) and nitrogen (N) cycling and greenhouse gas (GHG) emissions will be important for improved assessments of local and regional GHG budgets. This study presents the results of an analysis of the CO 2 and N 2 O fluxes from a coastal grassland ecosystem affected by episodic flooding that was of either a relatively short (SFS) or long (LFS) duration. Compared to the SFS, the annual CO 2 and N 2 O emissions were 1.4 and 1.3 times higher at the LFS, respectively. Mean CO 2 emissions during the period of standing water were 144 ± 18.18 and 111 ± 9.51 mg CO 2 -C m −2 h −1 , respectively, for the LFS and SFS sites. During the growing season, when there was no standing water, the CO 2 emissions were significantly larger from the LFS (244 ± 24.88 mg CO 2 -C m −2 h −1 ) than the SFS (183 ± 14.90 mg CO 2 -C m −2 h −1 ). Fluxes of N 2 O ranged from −0.37 to 0.65 mg N 2 O-N m −2 h −1 at the LFS and from −0.50 to 0.55 mg N 2 O-N m −2 h −1 at the SFS, with the larger emissions associated with the presence of standing water at the LFS but during the growing season at the SFS. Overall, soil temperature and moisture were identified as the main drivers of the seasonal changes in CO 2 fluxes, but neither adequately explained the variations in N 2 O fluxes. Analysis of total C, N, microbial biomass and Q 10 values indicated that the higher CO 2 emissions from the LFS were linked to the flooding-associated influx of nutrients and alterations in soil microbial populations. These results demonstrate that annual CO 2 and N 2 O emissions can be higher in longer-term flooded sites that receive significant amounts of nutrients, although this may depend on the restriction of diffusional limitations due to the presence of standing water to periods of the year when the potential for gaseous emissions are low.

“…Furthermore, the use of the river as a recreational area is a common activity in the community, so the wastewater inlet river denotes a focus of infection. The climate of the coastal plain of the Gulf of Mexico-a region that includes the community where the mesocosms are-has three periods comprising of: rainy season from July to October; cold front with strong winds and rain between November until February; and dry periods between March until June [18,19]. Weather in the region is tropical with an annual precipitation of 947.1 mm, and annual average temperature of 24.5 • C (26.1, 26.6, 25.2, and 20.3 • C in spring, summer, autumn, and winter, respectively).…”

Improving water quality is a relevant environmental aspect, and using constructed wetlands (CWs) is a sustainable option for this; both porous material filled cells and plants that collectively remove contaminants must be readily available and inexpensive. This study evaluated CWs and their functionality by comparing two ornamental plants (Spathiphyllum wallisii and Hedychium coronarium) planted in experimental mesocosm units filled with layers of porous river rock, tepezil, and soil, or in mesocosms with layers of porous river rock, and tepezil, without the presence of soil. The findings during the experiments (180 days), showed that the removal of pollutants (chemical oxygen demand (COD), total solids suspended (TSS), nitrogen as ammonium (N-NH 4 ), as nitrate (N-NO 3 ), and phosphate (P-PO 4 ) was 20-50% higher in mesocosms with vegetation that in the absence of this, and those mesocosms with the soil layer between 33-45% favored removal of P-PO 4 . Differences regarding of vegetation removal were only observed for N-NH 4 , being 25-45% higher in CWs with H. coronarium, compared with S. wallisii. Both species are suitable for using in CWs, for its functionality as phytoremediation, and aesthetic advantages could generate interest for wastewater treatment in rural communities, parks, schools or in domiciliary levels like floral flower boxes in the backyard. The study also revealed that a soil layer in CWs is necessary to increase the removal of P-PO 4 , an ion hardly eliminated in water treatment.

Coastal wetland restoration is an important activity to achieve greenhouse gas (GHG) reduction targets, improve water quality, and reach the Sustainable Development Goals. However, many uncertainties remain in connection with achieving, measuring, and reporting success from coastal wetland restoration.We measured levels of carbon (C) abatement and nitrogen (N) removal potential of restored coastal wetlands in subtropical Queensland, Australia. The site was originally a supratidal forest composed of Melaleuca spp. that was cleared and drained in the 1990s for sugarcane production. In 2010, tidal inundation was reinstated, and a mosaic of coastal vegetation (saltmarshes, mangroves, and supratidal forests) emerged. We measured soil GHG fluxes (CH 4 , N 2 O, CO 2 ) and sequestration of organic C in the trees and soil to estimate the net C abatement associated with the reference, converted, and restored sites. To assess the influence of restoration on water quality improvement, we measured denitrification and soil N accumulation. We calculated C abatement of 18.5 Mg CO 2Àeq ha À1 year À1 when sugarcane land transitioned to supratidal forests, 11.0 Mg CO 2Àeq ha À1 year À1 when the land transitioned to mangroves, and 6.2 Mg CO 2Àeq ha À1 year À1 when the land transitioned to saltmarshes. The C abatement was due to tree growth, soil accumulation, and reduced N 2 O emissions due to the cessation of fertilization. Carbon abatement was still positive, even accounting for CH 4 emissions, which increased in the wetlands due to flooding and N 2 O production due to enhanced levels of denitrification.Coastal wetland restoration in this subtropical setting effectively reduces CO 2 emissions while providing additional cobenefits, notably water quality improvement.
