There is an urgent need for countries to transition their national food and land-use systems toward food and nutritional security, climate stability, and environmental integrity. How can countries satisfy their demands while jointly delivering the required transformative change to achieve global sustainability targets? Here, we present a collaborative approach developed with the FABLE—Food, Agriculture, Biodiversity, Land, and...
Metabolic relationships of uncultured bacteria associated with the microalgae GambierdiscusNARA Subscribed
Summary Microbial communities inhabit algae cell surfaces and produce a variety of compounds that can impact the fitness of the host. These interactions have been studied via culturing, single‐gene diversity and metagenomic read survey methods that are limited by culturing biases and fragmented genetic characterizations. Higher‐resolution frameworks are needed to resolve the physiological interactions within these algal–bacter...
Aim A considerable proportion of the global savanna biome has been mis‐classified as forest, especially in Asia. However, the structure and responses of dominant tree species to fire can help to clarify this ambiguity. Here, we examine demographic structure and fire responses of four dominant tree species in a deciduous dipterocarp forest ( DDF ) of the continental Southeast Asia. We examine whether fire creates a tree‐recruit...
Genomic evidence for distinct carbon substrate preferences and ecological niches of B athyarchaeota in estuarine sedimentsNARA Subscribed
Summary Investigations of the biogeochemical roles of benthic A rchaea in marine sediments are hampered by the scarcity of cultured representatives. In order to determine their metabolic capacity, we reconstructed the genomic content of four widespread uncultured benthic Archaea recovered from estuary sediments at 48% to 95% completeness. Four genomic bins were found to belong to different subgroups of the former Miscellaneous...
A continent‐wide study reveals clear relationships between regional abiotic conditions and post‐dispersal seed predationNARA Subscribed
Aim Large‐scale patterns linking energy availability, biological productivity and diversity form a central focus of ecology. Despite evidence that the activity and abundance of animals may be limited by climatic variables associated with regional biological productivity (e.g. mean annual precipitation and annual actual evapotranspiration), it is unclear whether plant–granivore interactions are themselves influenced by these cl...
Novel hydrocarbon monooxygenase genes in the metatranscriptome of a natural deep‐sea hydrocarbon plumeNARA Subscribed
Summary Particulate membrane‐associated hydrocarbon monooxygenases ( pHMOs ) are critical components of the aerobic degradation pathway for low molecular weight hydrocarbons, including the potent greenhouse gas methane. Here, we analysed pHMO gene diversity in metagenomes and metatranscriptomes of hydrocarbon‐rich hydrothermal plumes in the G uaymas B asin ( GB ) and nearby background waters in the deep G ulf of C alifornia. S...
Terrestrial biosphere model performance for inter‐annual variability of land‐atmosphere CO 2 exchangeNARA Subscribed
Interannual variability in biosphere‐atmosphere exchange of CO 2 is driven by a diverse range of biotic and abiotic factors. Replicating this variability thus represents the ‘acid test’ for terrestrial biosphere models. Although such models are commonly used to project responses to both normal and anomalous variability in climate, they are rarely tested explicitly against inter‐annual variability in observations. Herein, using...
Summary We characterized the diversity of sulphate‐reducing bacteria (SRB) associated with South African gold mine boreholes and deep aquifer systems in Washington State, USA. Sterile cartridges filled with crushed country rock were installed on two hydrologically isolated and chemically distinct sites at depths of 3.2 and 2.7 km below the land surface (kmbls) to allow development of biofilms. Enrichments of sulphate‐reducing...
Microbiological, molecular biological and stable isotopic evidence for nitrogen fixation in the open waters of Lake MichiganNARA Subscribed
We have used a combination of microbiological, molecular biological and stable isotope methods to relate specific microbial populations to elemental cycling at an offshore site in Lake Michigan. Several lines of evidence suggest that atmospheric N 2 may be a significant source of nitrogen to the lake. Particulate organic nitrogen (PON) at ≈ 10–15 m depth in July and October had a δ 15 N of 0.5–1.5‰. These values closely reflec...
