|
|
The role of calcification in carbonate compensation pp894 - 900 Bernard P. Boudreau, Jack J. Middelburg & Yiming Luo doi:10.1038/s41561-018-0259-5 Changes in calcification of marine organisms must be considered to explain the deepening of carbonate accumulation during ocean recovery from acidification events. According to a literature synthesis and modelling, dissolution of sedimentary carbonate is not sufficient to explain observations. |

|
|
Formation of metre-scale bladed roughness on Europa's surface by ablation of ice pp901 - 904 Daniel E. J. Hobley, Jeffrey M. Moore, Alan D. Howard & Orkan M. Umurhan doi:10.1038/s41561-018-0235-0 Sublimation rates of water ice in equatorial regions of Jupiter's moon Europa are sufficient to sculpt bladed terrain that would pose a hazard to a potential lander mission. |

|
|
O2 solubility in Martian near-surface environments and implications for aerobic life pp905 - 909 Vlada Stamenkovic, Lewis M. Ward, Michael Mischna & Woodward W. Fischer doi:10.1038/s41561-018-0243-0 Despite little O2 in the Martian atmosphere, concentrations of dissolved O2 in near-surface brines on Mars may be sufficient to support aerobic life, according to solubility calculations. |
|
|
|
Persistent polar ocean warming in a strategically geoengineered climate pp910 - 914 John T. Fasullo, Simone Tilmes, Jadwiga H. Richter, Ben Kravitz, Douglas G. MacMartin et al. doi:10.1038/s41561-018-0249-7 Changes in the water cycle arising from a strategic geoengineering approach alter the ocean circulation and structure, according to an ensemble of simulations with an Earth System Model. |

Global patterns in wood carbon concentration across the world's trees and forests pp915 - 920 Adam R. Martin, Mahendra Doraisami & Sean C. Thomas doi:10.1038/s41561-018-0246-x Large variability of wood carbon fractions in different trees can lead to an error of up to 8.9% in carbon estimates for forests, according to an analysis of wood carbon data across global forested biomes. |
|
|
|
Low buffering capacity and slow recovery of anthropogenic phosphorus pollution in watersheds pp921 - 925 J. -O. Goyette, E. M. Bennett & R. Maranger doi:10.1038/s41561-018-0238-x Watersheds have a low buffering capacity for phosphorus inputs, and their recovery from phosphorus pollution can take over 2,000 years, according to an analysis of phosphorus data from a large North American river. |
|
|
|
Recent global decline in endorheic basin water storages pp926 - 932 Jida Wang, Chunqiao Song, John T. Reager, Fangfang Yao, James S. Famiglietti et al. doi:10.1038/s41561-018-0265-7 Hydrologically landlocked basins worldwide have experienced widespread decline in water storage over the past decade. |
|
|
|
Climatic and volcanic forcing of tropical belt northern boundary over the past 800 years pp933 - 938 R. Alfaro-Sánchez, H. Nguyen, S. Klesse, A. Hudson, S. Belmecheri et al. doi:10.1038/s41561-018-0242-1 Climate variability and volcanic forcing both influenced the latitudinal migration of the tropical belt over the past 800?years, according to an analysis of tree-ring widths in the Northern Hemisphere. |

|
Anthropogenic modification of vegetated landscapes in southern China from 6,000 years ago pp939 - 943 Zhongjing Cheng, Chengyu Weng, Stephan Steinke & Mahyar Mohtadi doi:10.1038/s41561-018-0250-1 Human land use changed the evolution of vegetation in southern China 6,000 years ago, according to analyses of a high-resolution marine pollen record. |

|
|
Rapid incision of the Mekong River in the middle Miocene linked to monsoonal precipitation pp944 - 948 Junsheng Nie, Gregory Ruetenik, Kerry Gallagher, Gregory Hoke, Carmala N. Garzione et al. doi:10.1038/s41561-018-0244-z Incision of the Mekong River that occurred after the uplift of the Tibetan Plateau may have been driven by a period of high monsoon precipitation, as suggested by age data from river bedrock samples and stream profile modelling. |

|
|
Systemic swings in end-Permian climate from Siberian Traps carbon and sulfur outgassing pp949 - 954 Benjamin A. Black, Ryan R. Neely, Jean-François Lamarque, Linda T. Elkins-Tanton, Jeffrey T. Kiehl et al. doi:10.1038/s41561-018-0261-y Carbon and sulfur release from the Siberian Traps igneous province caused climate swings during the end-Permian mass extinction, according to coupled global climate simulations. |

|
Deep embrittlement and complete rupture of the lithosphere during the Mw 8.2 Tehuantepec earthquake pp955 - 960 Diego Melgar, Angel Ruiz-Angulo, Emmanuel Soliman Garcia, Marina Manea, Vlad. C. Manea et al. doi:10.1038/s41561-018-0229-y Geophysical observations of the 2017 Tehuantepec earthquake suggest that oceanic lithosphere can sustain brittle behaviour and rupture in an earthquake at greater depths than previously assumed. |

|
|
Basal continental mantle lithosphere displaced by flat-slab subduction pp961 - 964 Gary J. Axen, Jolante W. van Wijk & Claire A. Currie doi:10.1038/s41561-018-0263-9 Continental mantle lithosphere is scraped from the base of the overriding plate by the underlying oceanic slab during flat subduction, according to numerical thermal–mechanical models. |
