Iron reducing bacteria play an essential role in Feammox. Rotational tillage reduced the microbial diversity of the iron-reducing bacteria, but it increased the abundance of iron-reducing bacteria at the genus level, and the dominate iron-reducing bacteria responsible for the Feammox process were <em>Anaeromyxobacter</em> and <em>Geobacter</em>.

Researches on tropical river systems frequently focused on continents and peninsulas, while little research has been conducted in tropical islands. In the present study, we conducted field surveys in a Pacific volcanic island, Pohnpei, Micronesia, and determined the substance composition of river waters (major ions, trace metals, nutrients, etc.) to quantify terrestrial material loading and biogeochemical influence on the surrounding oceans. In Pohnpei, total dissolved solutes were observed to be 71.4 mg/L; the NH<sub>4</sub><sup>+</sup>, NO<sub>3</sub><sup>−</sup>, PO<sub>4</sub><sup>−</sup>, and SiO<sub>3</sub><sup>2-</sup> concentrations were 0.46, 3.9, 0.52, 221.7 μmol/L, respectively; and NO<sub>2</sub><sup>−</sup> was lower than the detection limit (0.14 μmol/L). The trace metals concentrations of rivers in Pohnpei Island were much lower than records in tropical rivers of the world. The variation in concentration levels of major ions and nutrients among rivers was relatively limited. A similar pattern was observed in the distribution of Al and V. Trace elements, including As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Se, Sr, U and Zn in rivers were most enriched in Urban Area (human activity dominated region), compared with the Mixing Area (Multiple effect region) to Natural Area (natural weathering region). Exchangeable trace metals concentrations from suspended particulate matter (SPM) were lower than in dissolved state in river waters, while water-soluble, while acid-soluble metals concentrations in the sediment were much higher than in dissolved state in rivers. In our results, trace metals in Pohnpei rivers may mainly be influenced by domestic sewage and agricultural activity—these data can be used in biogeochemical models to estimate the contribution of domestic sewage. Furthermore, we have quantified the land-derived input of trace metals from tropical volcanic islands in Pacific (TVIP) into the surrounding oceans. Though the land area of TVIP only accounts for 0.1 % of global land area, the terrigenous inputs of some trace metals from TVIP account for approximately 1 %—and even more than 2 % of those in global riverine flux. Therefore, the nutrients and trace metals inputs from TVIP would be significant for the cycle of biogenic elements in the receiving ocean.</p></div>","PeriodicalId":51110,"journal":{"name":"Limnologica","volume":"101 ","pages":"Article 126087"},"PeriodicalIF":1.7,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43616603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One way to explain the stimulating effect of browning is to assume that <em>G. semen</em> combines photosynthesis with osmotrophy, the ability to utilize DOM as source of nutrients or energy. The present work tested this idea on a nearly unialgal <em>G. semen</em> bloom. Continuous vertical profiling found that each night, <em>G. semen</em> moved into the oxic-anoxic interface or the anoxic hypolimnion, i.e., into places where redox processes can give access to DOM via dissolution of ferric oxide-organic matter complexes. In the hypolimnion, conditions were right for a build-up of DOM, which, however, never happened. Optical analyses of hypolimnetic DOM indicated that the build-up was prevented by the removal of terrestrially derived DOM, which was correlated with <em>G. semen</em>. During the daytime, <em>G. semen</em> migrated into the epilimnion. Here, net oxygen production was near zero, indicating that <em>G. semen</em> combined photosynthesis with heterotrophic nutrition. Optical analyses of epilimnetic DOM hinted at the utilization of terrestrially derived DOM. Taken together, the above findings provide circumstantial evidence for <em>G. semen</em> combining photosynthesis with osmotrophy in nature. The proposed utilization of terrestrially derived DOM suggests that lake browning may favor <em>G. semen</em> by improving the access to DOM that the alga can utilize. Browning may also benefit <em>G. semen</em> by promoting summer anoxia that causes a reductive release of DOM from complexes with ferric oxides, improving the alga’s access to DOM.</p></div>","PeriodicalId":51110,"journal":{"name":"Limnologica","volume":"101 ","pages":"Article 126097"},"PeriodicalIF":1.7,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43951192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Relationships among catchment characteristics, habitat characteristics, and invertebrate assemblages were analyzed to elucidate the importance of land use and water quality in determining invertebrate assemblages. The analyses, using generalized linear models, showed that the relative area of urban land use of the catchment was strongly and positively related to the nutrient concentration of stream water and negatively related to the taxonomic richness of whole invertebrate assemblages and intolerant taxa. Furthermore, the richness metrics were low in streams with high nutrient concentrations, particularly PO<sub>4</sub>-P. The biplot of nonmetric multidimensional scaling showed that there was a gradient in community structure along the tolerance to water pollution that occurred in urban streams. These results collectively suggest that urban land use, not agricultural use, seemed to be a predominant factor causing nutrient enrichment in stream water and low invertebrate diversity through the exclusion of intolerant taxa in Indonesian streams whose catchments are exposed to rapid urbanization. We suggest that the impact of agricultural wastewater on stream water quality is concealed by the strong impact of urbanization when we consider that farming methods are, in general, not intensive in Indonesia, and that advanced wastewater treatment systems have not been widely introduced.
