A limited understanding of how hydrologically driven oxygen (O₂) variability affects microbial CH₄ cycling in diverse wetlands makes wetland CH₄ emissions uncertain. Transient O₂ exposure significantly stimulated anoxic CH₄ production in incubations of <i>Sphagnum</i> peat from a temperate bog by enriching for polyphenol oxidizers and polysaccharide degraders, enhancing substrate flow toward methanogenesis under subsequent anoxic conditions. To assess whether shifts in soil microbiome structure and function operate similarly across wetland types, here we examined the sensitivity of different wetland soils to transient oxygenation. In slurry incubations of <i>Sphagnum</i> peat from a minerotrophic fen, and sediments from a freshwater marsh and saltmarsh, we examined temporal shifts in microbiomes coupled with geochemical characterization of slurries and incubation headspaces. Oxygenation did not affect microbiome structure and anoxic CH₄ production in mineral-rich fen-origin peat and freshwater marsh soils. Key taxa linked to O₂-stimulated CH₄ production in the bog-origin peat were notably rare in the fen-origin peat, supporting microbiome structure as a primary determinant of wetland response to O₂ shifts. In contrast to freshwater wetland experiments, saltmarsh geochemistry-particularly pH-and microbiome structure were persistently and significantly altered postoxygenation, albeit with no significant impact on greenhouse gas emissions. These divergent responses suggest wetlands may be differentially resistant to O₂ fluctuations. With climate change driving greater O₂ variability in wetlands, our results inform mechanisms of wetland resistance and highlight microbiome structure as a potential resiliency biomarker.</p>","PeriodicalId":73516,"journal":{"name":"ISME communications","volume":"5 1","pages":"ycaf063"},"PeriodicalIF":5.1,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12075768/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082631","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, hosts may choose to allocate resources to regulate and recruit appropriate microbes. In doing so, hosts may incur an energetic cost and, in turn, these costs can affect host fitness. It remains unclear how hosts have evolved to balance the costs of expending resources to manage their microbiomes against the benefits that might accrue by doing so. To address this question, we extend a previously developed agent-based computational model of host-microbiome evolution by incorporating a resource provisioning process, to determine how hosts have evolved to balance the costs and benefits of expending resources to manage their microbiomes. Our results indicate that resource provisioning will evolve when hosts provide a high percentage of microbes to their offspring and contribute a low percentage of their microbiome to the environment. In contrast, resource provisioning will not evolve when hosts contribute a high percentage of their microbiome to the environment. This is because hosts that do not provide resources to acquire microbes can nonetheless still acquire microbes from the environmental contributions of hosts that do provide such resources. Since resource provisioning incurs a fitness cost to the host, over evolutionary time, resource provisioning will not be favored. Our results also show that hosts are less likely to provide resources to acquire beneficial microbes if hosts can obtain a high proportion of these microbes from the environment.</p>","PeriodicalId":73516,"journal":{"name":"ISME communications","volume":"5 1","pages":"ycaf059"},"PeriodicalIF":6.1,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12291540/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144735894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we integrated the core taxa identification with robust simulation modeling to reveal key environmental factors influencing the three core trophic groups (autotroph, heterotroph, and mixotroph), with a particular focus on mixoplankton. Temporally, core mixoplankton exhibited a higher relative proportion in spring and winter in contrast to core heterotrophs and a more uniform spatial distribution pattern. While seasonal patterns were observed in the environmental responses of the trophic groups, temperature, dissolved oxygen (DO), and nitrate (NO₃-N) were identified as the key drivers affecting the core mixoplankton by random forest. Furthermore, through univariate regression and generalized additive mixed model (GAMM), we captured the niche preferences of core mixoplankton across three stressors gradients and characterized the coupled additive or antagonistic effects. Notably, the potential optimal threshold for core mixoplankton was a high level of NO₃-N (0.64 mg/L), lower temperature (18.6°C), and DO (3.5 mg/L), which contrasted with the results obtained from single-factor regression analyses. Specifically, GAMM indicated that the preferred niche shifted upward for NO₃-N and downward for DO when three drivers were included simultaneously, while temperature remained constant.

By carrying out a manipulative mesocosm experiment with a 4°C increase, warming led to a significant decrease in the proportions of PUFA and Long-chain PUFA (LC-PUFA, >20 C) in periphyton from 13.32% to 9.90% and from 3.05% to 2.18%, respectively.

The rhizosphere was sampled at four sites, which captured a complete tillage erosion gradient from extremely eroded to depositional soils. The gene abundances characteristic of microbial N cycle guilds were assessed via metagenomics. The eroded sites showed the lowest plant productivity and soil mineral N availability, which was associated with an enrichment of <i>glnA</i> in the rhizosphere. Genes associated with dissimilatory nitrate-to-ammonium reducers and diazotrophy prevailed in the eroded soil profiles. The strongest correlations of the biomasses of rye plants along the catena with N cycle functions were observed for <i>norBC</i>. Thus, tillage erosion as a legacy of agricultural management aligns with substantial differences in rhizosphere microbiome functionality in N cycling.
