“…The sites of natural regrowth tended to have higher soil moisture, N and carbon concentrations and C:N, which all facilitate biogeochemical cycling as further evidenced by the high δ 15 N observed in the oldest area of natural regrowth. This is similar to previously observed relationships in mangroves of higher potential GHG fluxes and denitrification in areas of higher N and carbon (Hernández and Junca-Gómez, 2020;Hien et al, 2018a;Shiau et al, 2016). Soil moisture is more complex with both decreases in GHG flux (Cameron et al, 2019) and increases in CH 4 fluxes observed at higher soil moisture or water levels (Hernández and Junca-Gómez, 2020).…”

“…The downstream sampling site, Bali, is located 1 km from the mouth of the Tamsui River, and the upstream sampling site, Guandu, is located 8 km from the estuary. Kandelia obovate is the dominant vegetation, and Phragmites communis and Cyperus malaccensis are scattered along the edges of both mangrove forests [ 25 , 26 ]. Because of its geographical locations, the average salinity of Tamsui River at the time of the study was 21 psu downstream and 17 psu upstream.…”

“…In this study, we evaluated the variations in methanotrophic community compositions in two mangrove forests along the Tamsui estuary in Taiwan, which covers salinity ranges from mesohaline (5–18 psu) to polyhaline (18–30 psu) [ 25 ], and compared the results to our previous work, which was performed in a space between these two forests [ 19 ]. This study applied DNA-SIP, with the objective of determining whether there is a correlation between CH 4 oxidation kinetics and biogeographic patterns of methanotrophs in mangrove forests along a salinity gradient.…”

Niche Differentiation of Active Methane-Oxidizing Bacteria in Estuarine Mangrove Forest Soils in Taiwan

Mangrove forests are one of the important ecosystems in tropical coasts because of their high primary production, which they sustain by sequestering a substantial amount of CO2 into plant biomass. These forests often experience various levels of inundation and play an important role in CH4 emissions, but the taxonomy of methanotrophs in these systems remains poorly understood. In this study, DNA-based stable isotope probing showed significant niche differentiation in active aerobic methanotrophs in response to niche differentiation in upstream and downstream mangrove soils of the Tamsui estuary in northwestern Taiwan, in which salinity levels differ between winter and summer. Methylobacter and Methylomicrobium-like Type I methanotrophs dominated methane-oxidizing communities in the field conditions and were significantly 13C-labeled in both upstream and downstream sites, while Methylobacter were well adapted to high salinity and low temperature. The Type II methanotroph Methylocystis comprised only 10–15% of all the methane oxidizers in the upstream site but less than 5% at the downstream site under field conditions. 13C-DNA levels in Methylocystis were significantly lower than those in Type I methanotrophs, while phylogenetic analysis further revealed the presence of novel methane oxidizers that are phylogenetically distantly related to Type Ia in fresh and incubated soils at a downstream site. These results suggest that Type I methanotrophs display niche differentiation associated with environmental differences between upstream and downstream mangrove soils.

“…The e ciency of nitrate removal depends on carbon availability and quality, i.e. the chemical composition (Chen et al, 2017;Hume et al, 2002;Pulou et al, 2012;Shiau et al, 2016).…”

“…Interest in the nitrate reduction capacity of mangrove sediments has been growing and has been the subject of numerous studies conducted mainly on terrestrial mangroves (Fernandes et al, 2012a;Fernandes et al, 2016). Due to their hydromorphism and the accumulation of organic matter, mangrove sediments and soils are known to be potentially active reducing zones for nitrogen removal (Fernandes et al, 2016) used to treat nitrogen rich wastewater (Corredor and Morell, 1994;Shiau et al, 2016).…”

Mangrove sediments are generally nitrogen limited, with nitrate reduction to ammonium instead of denitrification in these sediments, resulting in nitrogen retention rather than nitrogen elimination. The goal of this work was to investigate the potential for nitrate reduction in marine mangrove sediments along a canal impacted by anthropogenic activity (Guadeloupe, West Indies) as a function of increased nitrogen load and how this would change nitrate transformation rates. In addition to that, the impact of the organic carbon load and the hydraulic retention time was assessed as factors affecting nitrate reduction rates. Potential nitrate reduction rates in the sediments along the canal, in the presence of indigenous organic carbon, ranged from 126 to 379 nmol cm‑3 h-1 generally increasing upon increasing supplied nitrate. The potential for nitrate reduction increased significantly with the addition of mangrove leaves, whereas the addition of simple, easily degradable carbon (acetate), resulted in an almost five-fold increase in nitrate reduction rates. The hydraulic retention time also had an impact on the nitrate reducing capacity due to an increased contact time between nitrate and the benthic microbial community. Marine mangrove sediments have a high potential to mitigate nitrogen pollution, mainly governed by the presence of large amounts of degradable carbon in the form of litter. The hydraulic retention time as tested experimentally that can be extrapolated to the time of inundation of the mangrove sediments may increase the potential for nitrate reduction. Whereas the sediments are daily exposed to a small tidal effect, increased water retention could increase the nitrogen elimination potential in these mangrove sediments.
