Mesophotic corals in Hawaii maintain autotrophy to survive low-light conditions: Stable isotope dataset
<p>In mesophotic coral ecosystems, reef-building corals and their photosynthetic symbionts can survive with less than 1% of surface irradiance. How depth-specialist corals rely upon autotrophically and heterotrophically-derived energy sources across the mesophotic zone remains unclear. We analyzed the stable carbon (δ<sup>13</sup>C) and nitrogen (δ<sup>15</sup>N) isotope values of a <em>Leptoseris </em>community from the ʻAuʻau Channel, Maui, Hawaiʻi (65-125 m) including four coral host species living symbiotically with three algal haplotypes. We characterized the isotope values of hosts and symbionts across species and depth to compare trophic strategies. Symbiont δ<sup>13</sup>C was consistently 0.5‰ higher than host δ<sup>13</sup>C at all depths. Mean colony host and symbiont δ<sup>15</sup>N differed by up to 3.7‰ at shallow depths and converged at deeper depths. These results suggest that both heterotrophy and autotrophy remained integral to colony survival across depth. The increasing similarity between host and symbiont δ<sup>15</sup>N at deeper depths suggests that nitrogen is more efficiently shared between mesophotic coral hosts and their algal symbionts to sustain autotrophy. Isotopic trends across depth did not generally vary by host species or algal haplotype, suggesting that photosynthesis remains essential to <em>Leptoseris </em>survival and growth despite low light availability in the mesophotic zone.</p>

Microbial autotrophy explains large-scale soil CO2 fixation
<p><span>Microbial communities play critical roles in fixing carbon from the atmosphere and fixing it in the soils. However, the large-scale variations and drivers of these microbial communities remain poorly understood. Here, we conducted a </span><span>large-scale</span><span> survey across China and found that soil autotrophic organisms are critical for explaining CO2 fluxes from the atmosphere to soils. In particular, we showed that large-scale variations in CO2 fixation rates are highly correlated to those in autotrophic bacteria and phototrophic protists. Paddy soils, supporting a larger proportion of obligate bacterial and protist autotrophs, display four-fold of CO2 fixation rates over upland and forest soils. Precipitation and pH, together with key ecological clusters of autotrophic microbes, also played important roles in controlling CO2 fixation. Our work provides a novel quantification on the contribution of terrestrial autotrophic microbes to soil CO2 fixation processes at a </span><span>large </span><span>scale, with implications for global carbon regulation under climate change.</span></p>
