Biological dinitrogen (N2) fixation sustains productivity in oligotrophic oceans and is now also thought to contribute substantially to the nitrogen supply in the warming Arctic. Here we demonstrate s...
Construction and operation of offshore wind farms can generate ecological disturbances that reshape coastal nekton habitats and affect marine biodiversity. To evaluate these effects, fixed-station sur...
At the subantarctic islands of South Georgia, albatrosses and petrels occupy a range of trophic niches, from zooplanktivore to top predator. Interspecific variation in mercury (Hg) contamination is th...
Trace elements occur naturally in the environment, but anthropogenic activities can amplify their release, increasing exposure and bioaccumulation in marine predators such as seabirds. Mercury (Hg) in...
Antarctic deep-sea ecosystems harboured unique and metabolically versatile micro-organisms that sustained key biogeochemical processes under extreme polar conditions. However, the genomic diversity an...
Global food security depends on tightly coupled international supply chains including natural gas, mineral fertilizers, and staple crops. Earlier research has examined potential consequences of disrup...
Urban populations in early modern to modern Japan depended strongly on rice and marine fish, raising the question of whether such apparently simple diets provided sufficient mineral availability in ev...
Ammonium availability may alter microbial access to persistent dissolved organic matter (DOM), but the response capacity of indigenous deep-water microbial communities remains poorly constrained. We u...
Deep-sea polymetallic nodule provinces host distinct benthic prokaryotic communities, yet viruses that regulate them remain largely unknown. Here, we established the viral genome dataset of the Clario...
Sponges, phylum Porifera, are long-lived and basal-branching metazoans that play important roles in ocean biogeochemistry and host diverse microbial communities. Siliceous sponges form a major clade o...
Under accelerating climate change and anthropogenic pressures, the global oceans face unprecedented threats from land-to-ocean contaminant discharge. Among these, herbicides are insidious but overlook...
The subseafloor biosphere is one of the largest ecosystems on Earth, hosting dense populations of microbial cells. Microbial activity is critical to the Earth's geochemical cycles of major elements su...
Exploring the natural diversity of phylogenetically distant nitrogenases is crucial for gaining new insights into the mechanism of atmospheric N2 fixation and unlocking biotechnological developments i...
Global warming and the resulting surface seawater stratification have led to dominance of small phytoplankton, driving substantial changes in planktonic ecosystem structure. This study investigates th...
Azaphilones are structurally diverse polyketides with broad bioactivities, among which chaetoviridins are distinguished by their chlorinated frameworks and anticancer potential. To expand the chemical...
The Indo-Pacific humpback dolphin (Sousa chinensis) and the Indo-Pacific finless porpoise (Neophocaena phocaenoides) are increasingly threatened by anthropogenic activity, however the relative influen...
Cold-water coral reefs host diverse microbial communities that play key roles in nutrient cycling and deep-sea productivity. Among them, methylotrophic bacteria metabolize and cycle one-carbon (C1) co...
In recent years, Marine Natural Products (MNPs) have emerged as a significant source for anticancer drug discovery, as many natural products can offer structural diversity, unique mechanisms of action...
Primary production in coastal upwelling regions has often been presumed to be supported primarily by allochthonous nutrients, but inconsistent nutrient delivery and the metabolic cost of nitrate assim...
Sulfate reduction is estimated to account for half of the organic carbon respiration in anoxic, organic-rich ocean sediments. Sulfate-reducing microorganisms (SRMs) typically oxidize simple carbon com...
