Microorganisms drive much of the marine nitrogen (N) cycle, which jointly controls primary production in global ocean. However, our understanding microbial communities driving ocean N cycle remains fragmented. Focusing on "who is doing what, where, and how?", this study draws a clear picture describing biogeography N-cycling by utilizing

Ocean microbial communities strongly influence the biogeochemistry, food webs, and climate of our planet. Despite recent advances in understanding their taxonomic genomic compositions, little is known about how transcriptomes vary globally. Here, we present a dataset 187 metatranscriptomes 370 metagenomes from 126 globally distributed sampling stations establish resource 47 million genes to study community-level across depth layers pole-to-pole. We examine gene expression changes community turnover as underlying mechanisms shaping along these axes environmental variation show individual contributions differ for multiple biogeochemically relevant processes. Furthermore, find relative contribution be significantly lower polar than non-polar waters hypothesize that regions, alterations activity response ocean warming will driven more by organismal composition regulatory mechanisms.Video AbstracteyJraWQiOiI4ZjUxYWNhY2IzYjhiNjNlNzFlYmIzYWFmYTU5NmZmYyIsImFsZyI6IlJTMjU2In0.eyJzdWIiOiI2ZDM3MTU3MTVlOWRjMjIwNjk3YmVlYTM4ZTFiYzA2NSIsImtpZCI6IjhmNTFhY2FjYjNiOGI2M2U3MWViYjNhYWZhNTk2ZmZjIiwiZXhwIjoxNjc5MzU4ODUzfQ.fR9n_CSDtj4NFNODQlYoh6-2hFK0eZLlkic_Tn2t6PReywCIRha7nJWNHEIa6TAVQq9D_kITAxjm7S04fAMziv-PQlBSfhL_LHBkD71WD64HFYZ-ET_4opJHSoEHKaf5frPuEEoZv_5n0WnuOl5fQlTHFURvD5f3GdcDiLnsUTIg_dKdeGl-KyXt6o9o5RDkcPiKgsNJkKAnw6nl263TvlMFG4WAW-wiQqbPBJCkmfoVvfMl1-qv6OMGso0eg7aFpbom6dqhlEZ4b4nBub03i9BEPccL7pf0G8bCICA2lqQB4j1ryqeK_zPImWClizV4XTOzLn7V-1MnIxPTsevMrg(mp4, (132.7 MB) Download video

The future response of marine ecosystem diversity to continued anthropogenic forcing is poorly constrained. Phytoplankton are a diverse set organisms that form the base ecosystem. Currently, ocean biogeochemistry and models used for climate change projections typically include only 2-3 phytoplankton types are, therefore, too simple adequately assess potential changes in plankton community structure. Here, we analyse complex model with 35 evaluate composition, turnover size structure over 21st century. We find rate becomes faster during this century, is, increasingly unstable change. Combined alterations diversity, our results imply loss ecological resilience likely knock-on effects on productivity functioning environment.

Abstract Background The ocean microbiota modulates global biogeochemical cycles and changes in its configuration may have large-scale consequences. Yet, the underlying ecological mechanisms structuring it are unclear. Here, we investigate how fundamental ( selection , dispersal drift ) shape smallest members of tropical subtropical surface-ocean microbiota: prokaryotes minute eukaryotes (picoeukaryotes). Furthermore, agents exerting abiotic on this assemblage as well spatial patterns emerging from action mechanisms. To explore this, analysed composition prokaryotic picoeukaryotic communities using DNA-sequence data (16S- 18S-rRNA genes) collected during circumglobal expeditions Malaspina - 2010 TARA Oceans . Results We found that two main components microbiota, picoeukaryotes, appear to be structured by different Picoeukaryotic were predominantly dispersal-limitation, while counterparts appeared shaped combined drift. Temperature-driven a major factor, out few selected factors, influencing species co-occurrence networks but not indicating association contribute understand structure response selection. Other measured variables seemed limited selective effects community ocean. Picoeukaryotes displayed higher differentiation between distance decay when compared prokaryotes, consistent with scenario limitation former after considering environmental heterogeneity. Lastly, random dynamics or more important role than counterparts. Conclusions differential seems cause contrasting biogeography, ocean, among surface plankton, picoeukaryotes.

Bacteria are essential parts of ecosystems and the most diverse organisms on planet. Yet, we still do not know which habitats support highest diversity bacteria across multiple scales. We analyzed alpha-, beta-, gamma-diversity bacterial assemblages using 11,680 samples compiled by Earth Microbiome Project. found that soils contained richness within a single sample (alpha-diversity), but sediment displayed gamma-diversity. Sediment, biofilms/mats, inland water exhibited variation in community composition among geographic locations (beta-diversity). Within soils, agricultural lands, hot deserts, grasslands, shrublands richness, while forests, cold tundra biomes consistently harbored fewer species. Surprisingly, encompassed similar levels beta-diversity as other soil biomes. These patterns were robust to alpha- beta- metrics used taxonomic binning approach. Overall, results idea spatial environmental heterogeneity is an important driver diversity.

Marine phytoplankton and zooplankton form the basis of ocean's food-web, yet impacts climate change on their biodiversity are poorly understood. Here, we use an ensemble species distribution models for a total 336 524 to determine present future habitat suitability patterns. For end this century, under high emission scenario, find overall increase in plankton richness driven by ocean warming, poleward shift species' distributions at median speed 35 km/decade. Phytoplankton is projected more than 16% over most regions except Arctic Ocean. In contrast, slightly decline tropics, but strongly temperate subpolar latitudes. these latitudes, nearly 40% assemblages replaced shifting species. This implies that threatens contribution communities plankton-mediated ecosystem services such as biological carbon sequestration.

Protists are the dominant eukaryotes in biosphere where they play key functional roles. While protists have been studied for over a century, it is high-throughput sequencing of molecular markers from environmental samples — approach metabarcoding that has revealed just how diverse, and abundant, these small organisms are. Metabarcoding now routine to survey diversity, so data rapidly accumulated multitude environments at different sampling scales. This mass provided unprecedented opportunities study taxonomic diversity protists, this organised space time. Here, we use as common thread discuss state knowledge protist research, technical considerations important insights gained on patterns processes might structured diversity. In addition insights, conclude verge an exciting added dimension thanks maturation long-read sequencing, robust eco-evolutionary framework within reach.
