Thermal buffering by tidally generated internal bores on the shallows of a remote coral atoll
Abstract Coral reefs are being degraded globally, largely due to coral bleaching from rising ocean temperatures. Internal bores, generated by nonlinear internal waves, can help mitigate this stress by delivering cooler, nutrient‐rich water to shallow reefs (

Large methane oxidation across an oxygen gradient in Baltic Sea deep waters
Abstract Robust estimations of methane (CH4) oxidation in marginal seas remain elusive, making CH4 budgets particularly uncertain. Here, we investigate the CH4 benthic source and bottom layer oxidation across the entire Baltic Sea using concentration and stable isotope (δ13C‐CH4) profiles along…

A matter of salt: Global assessment of the effect of salt ionic composition as a driver of aquatic bacterial diversity
Abstract While the influence of salinity on microbial diversity is well documented in marine and brackish ecosystems, the impact of different dissolved inorganic ion types remains largely unexplored. In this study, we assessed how ionic composition shapes planktonic bacterial community structure in…

Projecting biomass declines in the St Helena marine protected area food web due to climate change
Abstract Understanding marine ecosystem responses to climate change is crucial for developing ecosystem‐based adaptation strategies. We applied the StrathE2E model to assess climate change impacts on the food web of the St Helena marine protected area (SHMPA). The model was parameterized using two…

Drastic suppression of benthic nitrogen fixation by restructuring diazotrophic communities following tidal wetland conversion to aquaculture ponds
Abstract Tidal wetland reclamation is a widespread anthropogenic disturbance that alters sediment biogeochemistry; however, its impacts on biological nitrogen fixation (BNF) and diazotrophic communities remain poorly understood. Here, we integrated 15N isotope labeling, metagenomic sequencing, and…

Transient shifts in Bering Sea shelf phytoplankton size structure in response to wind‐induced mixing
Abstract Phytoplankton community size structure is a key attribute that influences pelagic trophic energy transfer and the vertical flux of organic matter to benthic food webs. To capture the ephemeral scale of phytoplankton population size spectra we developed an approach, combining long‐term…

Parasite infection shapes the pathobiome and behavior of marine zooplankton
Abstract When assessing the total impact of disease in a host, it is important to consider not only the disease‐carrying agent but also all symbionts, as they affect and are affected by the course of disease. This concept of a pathobiome is increasingly recognized in disease ecology, but is not…

Revisiting the latitudinal cline of catadromy in Japanese eels
Abstract Partial migration of organisms, in which only a subset of a population migrates, plays an important role in life‐history strategies and population resilience in many taxa, yet the mechanisms shaping it under changing environments need further investigation. Otolith element profiles of…

Rooted macrophytes reduce sediment CH4 storage and net production: An experimental approach using a novel scanning method
Abstract Methane (CH4) emissions from freshwater ecosystems are significant but rarely quantified in vegetated zones. We assessed the influence of five macrophyte species that root in the sediment differing in growth form and root biomass on CH4 emissions and sediment gas storage. Using a novel…

Nitric oxide supersaturation in the surface waters of the oligotrophic Atlantic Ocean
Abstract Atmospheric nitric oxide (NO) is a pollutant and climate‐relevant trace gas. Dissolved NO accumulates in the surface ocean and therefore the ocean is a natural source of atmospheric NO. It is generally assumed that NO in the surface ocean is produced photochemically from nitrite (NO2−)…

Coupling air–water CO2 flux and primary production dynamics under hydrologic variability in a large urban estuary
Abstract Estuaries are critical for land‐ocean carbon exchange, but coupling mechanisms between air–sea CO2 fluxes (FCO2) and phytoplankton gross primary productivity (GPP) remain poorly understood. This study used high‐frequency underway monitoring in the Lingdingyang Estuary to resolve…

Pigment evidence of phytoplankton community shifts driven by rapid changes in the western Arctic Ocean, 2008–2018
Abstract Rapid warming in the Arctic have influenced the ecological and biogeochemical systems in the Arctic Ocean, particularly the phytoplankton community that plays a fundamental role in food webs and carbon cycle. Our 10‐yr study found an abrupt change in the phytoplankton community in the…

The cycling of glycine betaine and homarine in marine microbial communities: Quantitative flux measurements and the role of competitive uptake inhibition
Abstract The flux of carbon through the labile dissolved organic matter (DOM) pool supports marine microbial communities and represents the fate of approximately half of marine net primary production (NPP). However, the behavior of individual chemical structures that make up labile DOM remain…

Wave‐driven transport controls bacterioplankton community differentiation among coral reef habitats
Abstract The existence of highly productive coral reefs within oligotrophic gyres is in part due to intensive recycling of macronutrients and organic matter by microbes. Therefore, characterizing reef bacterioplankton communities is key for understanding reef metabolism and biogeochemical…

Clumped isotopes as fingerprints of microbial methane production pathways in marine sediments
Abstract Microbial methanogenesis in marine sediments produces significant amounts of methane from various substrates; however, identifying the active pathways in situ remains challenging. While the bulk and clumped isotopic signatures of methane from different pathways have been studied in pure…

Oceanographic heterogeneity facilitates gelatinous zooplankton niche space and diversity
Abstract Gelatinous zooplankton serve diverse ecological roles in shelf food webs—from grazers to predators. However, their spatial niches are poorly resolved, especially at detailed taxonomic levels, due to conventional techniques that are unable to measure distributions at fine spatial scales…

Ship waves induce methane ebullition in the littoral zone of a large lake
Abstract Methane (CH4) ebullition is a major emission pathway in lakes. However, ebullition remains difficult to assess, and data from large lakes are scarce. This study investigates ebullition in the littoral zone of a large lake, demonstrating that ship waves, even after traveling long distances…

Phosphate limitation threshold for phosphonate utilization and methane production by carbon–phosphorus lyase in Stutzerimonas frequens
Abstract The surface ocean is an important source of methane to the atmosphere, contributing 4% of natural global production. The degradation of methylphosphonate (MPn) is a key methane production pathway in the aerobic euphotic zone. Methylphosphonate is an important component of dissolved organic…

Imprint of Indian Ocean Dipole on nitrous oxide dynamics
Abstract The northern Indian Ocean is a hotspot of nitrous oxide (N2O) emissions, with strong seasonal monsoons and interannual Indian Ocean Dipole (IOD) variability. We examine the IOD influence on N2O seasonality using a regional ocean model covering 1981–2020, with a focus on the coastal ocean…

Rhythms of lysis: Viral regulation of prokaryotic turnover across diel cycles
Abstract Diel rhythms structure microbial activity in the ocean, yet the role of viral lysis in driving short‐term community dynamics remains poorly understood. Here, we combined dilution experiments, high‐resolution microbiome sampling and extracellular ribosome sequencing to investigate diel…
