The global distribution and climate resilience of marine heterotrophic prokaryotes
11 pages, 4 figures, supplementary information https://doi.org/10.1038/s41467-024-50635-z.-- Data availability: Raw prokaryotic abundance, cell carbon, specific-production rates and growth efficiency data used in this study are available here: https://doi.org/10.5281/zenodo.12741063. Heterotrophic bacterial and archaeal abundance were obtained from three published studies9,26,27, while cell-specific carbon data (previously unpublished) were obtained from the Malaspina-2010 expedition28. Specific-production rate data were compiled from the Malaspina-201028 (previously unpublished in the form used here, but can be derived from data published in ref. 39), Hotmix87 (previously unpublished) and Latitud51 expeditions, the Blanes Bay Microbial Observatory (previously unpublished; http://bbmo.icm.csic.es/) and the Western Arctic and Ross Sea50. Finally, prokaryotic growth efficiency data were compiled and published previously by Carol Robinson34. Global, depth-resolved predictions of prokaryotic abundance, cell carbon, biomass and metabolic activity generated in this study are available here: https://doi.org/10.5281/zenodo.12541052. Environmental data used to generate these predictions were obtained from World Ocean Atlas 2018 and MODIS-Aqua (for chlorophyll a only), and is also available here: https://doi.org/10.5281/zenodo.12741063. For the climate change projections, environmental inputs were sourced from four climate models from CMIP6 (Methods). Climate model data are available from the Earth System Grid Federation here: https://esgf-data.dkrz.de/projects/esgf-dkrz/).

Yet, there is limited understanding about how prokaryotes vary across global environmental gradients, and how their global abundance and metabolic activity (production and respiration) may be affected by climate change. Using global datasets of prokaryotic abundance, cell carbon and metabolic activity we reveal that mean prokaryotic biomass varies by just under 3-fold across the global surface ocean, while total prokaryotic metabolic activity increases by more than one order of magnitude from polar to tropical coastal and upwelling regions. Under climate change, global prokaryotic biomass in surface waters is projected to decline ~1.5% per °C of warming, while prokaryotic respiration will increase ~3.5% ( ~ 0.85 Pg C yr−1). The rate of prokaryotic biomass decline is one-third that of zooplankton and fish, while the rate of increase in prokaryotic respiration is double. This suggests that future, warmer oceans could be increasingly dominated by prokaryotes, diverting a growing proportion of primary production into microbial food webs and away from higher trophic levels as well as reducing the capacity of the deep ocean to sequester carbon, all else being equal With the institutional support of the ‘Severo Ochoa Centre of Excellence’ accreditation (CEX2019-000928-S) Peer reviewed 2024-10-04T10:57:48Z 2024-10-04T10:57:48Z 2024-08 artículo http://purl.org/coar/resource_type/c_6501 Nature Communications 15: 6943 (2024) CEX2019-000928-S http://hdl.handle.net/10261/369115 10.1038/s41467-024-50635-z 2041-1723 http://dx.doi.org/10.13039/501100011033 en Publisher's version https://doi.org/10.1038/s41467-024-50635-z Sí open Nature Publishing Group |
