    Abstract Full‐pattern fitting of X‐ray powder diffraction (XRPD) data using reference materials has attracted increasing attention as a high‐throughput method to determine the contents of long‐range‐ordered (i.e., crystalline) materials in soils. We hypothesized that this XRPD method can also be used to quantify short‐range‐ordered (SRO) materials with low crystallinity, despite their much weaker and broader diffraction. To obtain soil samples with a wide range of allophane and organic matter (OM) contents, surface and subsurface soils were collected from five profiles in northern Japan. A full factorial design was used to identify the optimal combination of reference SRO materials, including allophane, OM, and phytolith, for XRPD method using full‐pattern fitting. The allophane and OM contents determined by XRPD were broadly but unexpectedly consistent with those obtained by conventional methods. In addition, the allophane and OM contents determined by XRPD showed significant positive correlations with phosphate absorption coefficient and cation exchange capacity, respectively (Spearman's rank correlation, p  < 0.001), consistent with the relationships observed by the conventional methods. These results suggest that, although accurate quantification of samples with low contents (i.e., OM < 10 wt.%) remains challenging, state‐of‐the‐art XRPD method using full‐pattern fitting alone provides a promising new approach for rapid evaluation of soil properties and functions through the quantification of both crystalline and low‐crystalline materials.

    Abstract The interaction between dissolved organic matter (DOM) and microbial communities is a critical yet understudied driver of biogeochemical cycling in aquatic ecosystems. Understanding these interactions is essential for elucidating the chemical and microbial dynamics that sustain ecosystem functionings. Here, we combined non-target ultra high-resolution mass spectrometry-based environmental metabolome analysis with microbiome analysis to conduct the first comprehensive investigation of DOM-microbe linkages in both the epilimnion and oxygenated hypolimnion of a deep freshwater lake throughout the stratification period, with Lake Biwa (Japan) as a model system. To facilitate interpretation of DOM-microbe networks, we developed an integrated compound category classification (IC3) framework for assigning molecular formulae (MFs) to specific compound categories. Using a compositional data analysis framework, we identified specific MFs and bacterial taxa that covaried in the hypolimnion, which exhibited substantially more complex networks than the epilimnion. These networks encompassed 1705 out of the 1755 common MFs, representing the majority of total peak intensities, underscoring stronger DOM-microbe coupling in deep waters. Hypolimnion specialist bacteria were associated with specific MFs and co-ocuuring taxa, providing environmental metabolomic evidence for substrate preference and potential symbiotic relations. Notably, more than three-fourths of these MFs in relative abundance were classified as recalcitrant, including lipid-, lignin-, tannin-like, and carboxyl-rich alicyclic molecules, suggesting the capability of hypolimnion specialists to use or produce these compounds. Our study offers the first high-resolution insights into DOM-microbe associations in a deep freshwater lake and establishes a framework for more efficient and robust analyses of such interactions.

    Abstract Around one-third of the world’s most carbon-rich ecosystems, mangrove forests, have already been destroyed in Thailand owing to coastal development and aquaculture. Improving these degraded areas through mangrove plantations can restore various coastal ecosystem services, including CO2 absorption and protection against wave action. This study examines the biomass of three coastal mangrove plantations (Avicennia alba) of different ages in Samut Prakarn province, Central Thailand. Our aim was to understand the forest biomass recovery during the early stages of development, particularly fine root biomass expansion. In the chronosequence of the mangrove plantations, woody biomass increased by 40% over four years from 79.7 ± 11.2 Mg C ha-1 to 111.7 ± 12.3 Mg C ha−1. Fine root biomass up to a depth of 100 cm was 4.47 ± 0.33 Mg C ha−1, 4.24 ± 0.63 Mg C ha−1, and 6.92 ± 0.32 Mg C ha−1 at 10, 12, and 14 year-old sites, respectively. Remarkably, the fine root biomass of 14-year-old site was significantly higher than those of the younger sites due to increase of the biomass at 15–30 cm and 30–50 cm depths. Our findings reveal that the biomass recovery in developing mangrove plantations exhibit rapid expansion of fine roots in deeper soil layers.

    AbstractMangrove‐fringed estuaries are intertidal ecosystems discharging significant amounts of dissolved organic matter (DOM) into coastal oceans. DOM in these ecosystems is derived from autochthonous production, fluvial input, and mangrove porewater outwelling; however, differentiating between these sources remains challenging. Our incomplete understanding of the biogeochemical factors controlling DOM dynamics and its relationship with nutrient and trace metal cycling still hinders the formulation of elemental budgets in coastal environments. Here, we relate the DOM composition in a mangrove‐fringed estuary in North Brazil (Amazonia) to the redox conditions at the formation sites. We combined molecular DOM analyses via ultrahigh‐resolution mass spectrometry (FT‐ICR‐MS) with parallel factor analysis of excitation–emission fluorescence matrices (EEM‐PARAFAC), nutrient and redox‐sensitive trace metal analyses. During low tide, the influx of oxygen‐depleted porewater carried terrigenous DOM, inorganic nutrients, and trace metals into the mangrove‐fringed creeks. Precipitation of metal(hydr)oxides and microbial turnover controlled nutrient and trace metal dynamics in the estuary. The highest inorganic nitrogen concentrations within the upper mangrove‐fringed estuary indicated outwelling from mangrove sediments as an essential source. Phosphate concentrations were highest within the lower mangrove‐fringed estuary, where available phosphate likely exceeded precipitation with iron(hydr)oxides. We tracked the DOM transport to the coastal ocean using a novel molecular index derived from sulfidic porewater (ISuP). Outwelling of recalcitrant DOM from mangrove habitats is relevant in the context of blue carbon storage. Therefore, applying our molecular proxy (ISuP), together with trace‐metal and optical DOM analyses, is a powerful approach for differentiating contributions of diverse DOM sources in highly complex coastal ecosystems.

    Sewage sludge is generated 2.26 million Mg annually in Japan, and its dealing is one of the social problems. This study aimed to promote the application of dried sewage sludge in farmlands for recycling purposes. We composted sludge and bamboo chips in the ratios of 5 : 5, 7 : 3, and 9 : 1. Characteristics of hot water extracts during composting were analyzed approximately every week until the end of composting process (41 days) by testing inhibition of germination of Japanese mustard spinach (Brassica rapa var. perviridis) and by chemical analyses such as those using UV-vis spectroscopy and those involving dissolved organic carbon measurement. The concentration of ammonia, which is one of the strongest odor sources, decreased by about 60％ in the first 2 weeks of composting. The pH, electrical conductivity, and E2/E3 tended to decrease, whereas specific UV absorbance (SUVA254) tended to increase during composting, suggesting the progression of humification and maturation of composts. Although the 7 : 3 and 9 : 1 compost extracts demonstrated considerable germination inhibition in the early stages of composting, the inhibition was alleviated as maturation progressed to 28 days. Inhibition was not observed in the 5 : 5 compost extract, and heavy metals did not exceed the safety standard, so the compost did not exhibit harmful effects on crop growth or safety. We also performed three replicates of a field growth experiment using Tanbaguro black soybean (Glycine max) with and without addition of 50-day-old compost (5 : 5, 7 : 3, and 9 : 1). Results showed that addition of the composts significantly increased the main stem length and the number of pods (p<0.01). Soybean yield was the highest in the 9 : 1 compost addition group, although this difference was not significant. These results suggest that composting of dried sewage sludge and bamboo chips is effective in agricultural production as it recycles local resources, reduces odor, and does not inhibit germination.

    Mangrove forests are tropical forests with carbon-rich soil. Dissolved organic matter (DOM) is important for investigating the mangrove carbon cycle and ecological roles because the forests connect the river tributaries with the coast via rivers running through them. The ecological functions and turnover rate of DOM depend on its composition. Therefore, we characterized the DOM of the Fukido River in a mangrove forest by analyzing the percentage of humic substances (%HS) in DOM. Water sampling from the headwaters to the sea revealed that %HS declined going toward the sea due to mixing with low-%HS seawater and the possible selective precipitation of HS into mangrove soil. The headwaters had a higher %HS than most clear water rivers and may be an important supply of HS for mangrove and coastal areas. The sequential extraction of water-extractable organic matter from mangrove soil (sampling depth: 0–25 cm) using ultrapure water indicated a significant increase in HS concentration along with a decline in salinity. These results suggest that high salinity is responsible for the selective accumulation of HS in mangrove soil, which can be a key to elucidating the mechanism of organic matter accumulation in mangrove soils.

    海洋や湖沼などの水中には有機物が何十万種類も溶けていて、これらは総じて溶存有機物と呼ばれています。水圏生態系の微生物はこの溶存有機物を食べて生活しているため、溶存有機物の分子レベルの複雑多様性は微生物から始まる水圏生態系を下支えしています。私は、溶存有機物の多様性の実態や多様化プロセスを明らかにすることで、水圏生態系の現状把握や健康診断ができると考えています。

    海洋によるCO2吸収速度を正しく見積もり、その将来変動を予測するには、難分解な非生物態有機炭素プールの挙動を知る必要がある。本研究では、海洋微生物が生成する超難分解な腐植様蛍光性溶存有機物(FDOM)を対象とする。FDOMの蛍光強度を炭素濃度に換算可能な式を世界で初めて開発する。広域観測および数値モデルと組み合わせることで、全海洋のFDOM生成フラックスを定量化し、温暖化に伴うその変動を予測する。

    海草藻場や塩性湿地等の浅海域植生帯の堆積物は、植生帯の一次生産に由来する有機炭素の大規模な貯留の場となっており、地球規模の二酸化炭素吸収源として注目されているが、堆積物中に炭素が貯留されるための条件となる有機炭素の難分解化のメカニズムに関しては十分な理解が得られていない。本研究課題では、潜在的な重要性にもかかわらず研究が立ち後れている硫黄サイクルとの相互作用の観点に特に注目して浅海域植生帯の堆積物における有機炭素貯留のメカニズムの解明を目指し、１，沿岸植生帯堆積物の実地調査、２．有機炭素長期貯留の数値モデル、３．免疫学的検出手法の開発という３つの方面から研究に取り組んでいる。 初年度の2022年度はまず堆積物中での非生物学的な加硫反応による有機物難分解化への寄与を定量的に明らかにするために、東京大学大気海洋研究所において有機態硫黄を分離精製するための試料処理ラインを構築するとともに、既設の質量分析設備を改良して硫黄安定同位体比の高精度測定を可能にする作業を行い、アーカイブ試料に適用して性能確認と再現性の検証を行った。一方、堆積物中の硫黄の酸化還元反応と有機物との相互作用を記述する鉛直一次元の数理モデルの開発に着手し、亜熱帯海草藻場（石垣島吹通川河口域）をモデルシステムとして、モデルに必要となる基礎的な現場データの収集を進めた。また並行して、有機硫黄化合物に対する免疫学的検出（サンドイッチELISA）を行うために必要となる設備の整備を進め、そのための基質として、現場で堆積物中に観察されるものと同様の有機硫黄化合物を実験室内で人為的に生成させる方法の検討を行った。

    地球上で最もCarbon-richな生態系であるマングローブ林は、同時に最も脆弱な生態系でもあり、その保全は地球温暖化緩和のための重要な戦略である。タイ王国では、エビ養殖のために多くのマングローブ林が破壊されてきたが、近年になって、生産性の低下に伴って古い養殖池の放 棄が見られるようになり、マングローブ林植林が進められている。このような荒廃地での生態系炭素貯留量の回復は、その保全と同等の温暖化緩和のための低コストオプションになり得るが、まだ研究例は少ない。本研究の目的は、タイ王国でのマングローブ植林が、生態系炭素貯留量(特に土壌有機炭素)の蓄積に与える効果を評価して、蓄積した有機物の起源を明らかにする事でてある。また、日本とタイの若手研究者の交流を通して、マングローブ林の土壌有機炭素動態についての国際的な研究の活性化を目指す。本年度は、海外での調査許可申請と、許可を取得後に実際の植林地での測量や土壌サンプリングのための調査を3月の乾季に予定していた。しかしタイへの入国がCovid-19の影響で難しく、許可証の取得が不可能となり、これらの仕事は次年度に延期にせざるを得なかった。したがって、本年度は、カウンターパートであるチュラロンコン大学のSasitorn准教授と、メールやZOOMなどで許可申請のための申請書のやりとり、および実際の現地調査のための打ち合わせなどを行なった。また、土壌の比重分画による細根分離のための予備的な実験などを行なった。

    2023年度は、2022年度に完成させたFDOMセンサー（腐植物質様蛍光溶存有機物センサー）によって水深プロファイルの観測と2023年9月から12月今津沖中央（水深89m地点）の水深85mで長期係留観測を行った。水深プロファイル観測では、現場環境の湖底付近において溶存酸素濃度の影響により実験室に持ち帰った湖水試料を蛍光分光光度計で測定した蛍光特性と異なる結果となった。低酸素化した湖底環境で腐植物質様蛍光強度が高くなる傾向を示し、腐植物質の構造に豊富に含まれるキノン骨格のアントラキノン、セミキノン及びヒドロキノンの平衡がヒドロキノンに傾いたためと推測された。この時、塩濃度、温度の変化もなかった。 キノン骨格の溶存酸素量及び酸化還元雰囲気の変化による平衡移動にともなう構造変換では、過酸化水素が生成されることが知られている。我々は、2010年以降に確認されるようになった琵琶湖深層水域における貧酸素水鬼の湖内流による移動の際、過酸化水素が継続的に生成されている可能性を推測した。そこで、琵琶湖の底質から抽出したフミン酸を蒸留水に分散させ、過酸化水素から生成するヒドロキシラジカルをトラップするテレフタル酸ナトリウムをフミン酸分散溶液に添加し、冷暗所で酸素パージと窒素パージとを繰り返す操作を行った。各操作後の試料をろ過し、蛍光検出ＨＰＬＣ法でヒドロキシテレフタル酸濃度を測定した。その結果、窒素パージの後に大きくヒドロキシテレフタル酸濃度が増加した。また、酸素パージの後でもヒドロキシテレフタル酸濃度は増加した。このことから貧酸素水塊の移動に伴って過酸化水素とそれから誘導されるヒドロキシラジカルが湖底で生成されていることを示唆する結果を得ることができた。

    メインの調査地である石垣島吹通川マングローブ林においては，予定していた調査および研究を滞りなく実施し，研究成果は前年度と合わせ6本の論文として既に公表済みであり，さらに2本が投稿中である．比較研究としてタイ王国トラート川河口のマングローブ林の土壌調査を行い，その結果も現在執筆中である．さらに，予定にはなかった奄美大島のマングローブ林においても調査を行うことができ，次の研究に向けた計画を練るうえで貴重な情報を得ることができた．2年間という短い特別研究員としての期間を十分に活用し，大きな成果を得ることができたと考えている．
    採択課題のメインはマングローブ林内土壌への土壌有機物の貯留メカニズムの解明であった．前年度の結果と合わせ，高塩濃度による河川中の溶存有機物の沈殿および土壌中の土壌有機物の凝集・固定化が効いていることを見出し，国際誌に発表した．さらに，塩濃度が高い環境で土壌有機物が固定化されるということは，逆に塩濃度が低下すると土壌有機物が固定化状態から解放され，マングローブ林土壌から沿岸海域へと溶存有機物として流出することを示唆する．そこで，当該マングローブ林内を流れる吹通川において2年間の溶存有機物濃度のモニタリング調査をおこなった．その結果，台風由来の大雨による淡水の流入が土壌の塩濃度を低下させ，通常時の数倍濃度の溶存有機物が流出することを発見した．このことはマングローブ林における高塩濃度による土壌有機物の固定化は決して安定したメカニズムではなく，淡水―海水の相対寄与によってダイナミックに変わりうることを示している．これは河川による淡水の流入と潮汐による海水の流入があるマングローブ林に特異な現象であり，今後のさらなる研究が必要である．
