    Ecosystems have long been shaped by phosphorus limitation. We need to better understand how natural and human-caused shifts in the phosphorus cycle disrupt the Earth system.

  • Q&A |

    Nature Geoscience spoke with Dr Shlomit Sharoni, an ocean biogeochemist at Massachusetts Institute of Technology, and Dr Kelly Andersen, a tropical ecologist at Nanyang Technological University about the interplay between phosphorous cycling and the ecosystems they study.

    From Dutch painters to ocean sediments, Caroline Slomp discusses the role vivianite plays in the distribution of phosphorus, an essential nutrient for life.

    A review of aqueous phosphorus availability on the Earth’s early surface suggests a range of phosphorus sources supplied the prebiotic Earth, but that phosphorus availability declined as life evolved and altered geochemical cycling.

    Projections of forest aboveground carbon storage potential in the United States show divergent results across different modelling approaches due to uncertainties in the estimated impact of climate risks, according to a comparison of modelling results.

    A field-based study of 4.5 years of whole-soil warming reveals that warming stimulates loss of structurally complex organic carbon at the same rate as that for bulk organic carbon in subsoil.

    Structurally complex polymeric compounds, such as pyrogenic carbon, that have been previously considered long-term carbon sinks in soils can rapidly be lost by decomposition at warmer temperatures, according to 4.5 years of whole-soil warming experiments.

    Iron input into the ocean is a key control on mineral–organic preservation, and therefore the accumulation of oxygen in Earth’s atmosphere, according to a theoretical model and supported by proxy records for iron phases and cycling.

    Some coastal marshes may have a hard time building soil elevation under future climate conditions, although this may reduce methane emissions, according to four years of field manipulation of warming and elevated CO2 in a coastal wetland.

    Widespread injection of deep water from the Barents Sea into the Nansen Basin makes a substantial contribution to carbon sequestration in the Arctic Ocean, and feeds the deep sea community.

    Marine phytoplankton both follow and actively influence the environment they inhabit. Unpacking the complex ecological and biogeochemical roles of these tiny organisms can help reveal the workings of the Earth system.

    The biological processes that control the release of carbon stored in land are dependent on water availability. A global analysis of temperature sensitivity reveals how hydrometeorological processes modulate the response of land carbon turnover to temperature.

    Mediation by iron minerals in the non-biological production of nitrous and nitric oxides may have driven the nitrogen cycle in the Archean ocean. This system may also have shaped the function and composition of the early marine ecosystem.

    Anthropogenic nitrogen deposition is known to affect forest soil respiration, but it remains unclear how soil respiration responds to nitrogen deposition over time. Monitoring of CO2 emissions over 9–13 years of nitrogen-addition treatments in three tropical forests in southern China reveals a three-phase pattern of soil respiration.

    Enhanced formation of clay in marine sediments in the lead up to the end-Permian mass extinction likely pulled the Earth back into a hot, high-CO2 state similar to that of the Precambrian.

    Cellular modelling and geochemical analyses reveal that a dominant group of phytoplankton changed their carbonate production as atmospheric CO2 levels declined from peak levels in the warm early Eocene, hinting at a positive feedback in the global carbon cycle.

    Modelling of the effect of reservoirs on the climate through time (1900 to 2060) revealed that although carbon emissions peaked in 1987, reservoir-induced radiative forcing will continue to rise for the next decades. Over time, reservoir emissions are shifting from carbon dioxide to methane-dominated pathways, on which knowledge is largely lacking.

    Bruce Fouke explores the biomineralization of calcium oxalate and apatite kidney stones and the opportunities that lie at the intersection of geology, biology and medicine; a transdisciplinary effort traced back some 350 years.

    The colonization of Earth landmasses by vascular plants around 430 million years ago substantially impacted erosion and sediment transport mechanisms. This left behind fingerprints in magmatic rocks, linking the evolution of Earth’s biosphere with its internal processes.
