    Dust deposition brings iron that fuels ocean productivity, a connection impacting climate over geological time. Here the authors use sediment cores to show that in contrast to dynamics today, during the last glacial maximum westerly winds shuttled dust from Australia and South America around Antarctica and into the South Pacific.

    Tree mortality has been shown to be the dominant control on carbon storage in Amazon forests, but little is known of how and why Amazon forest trees die. Here the authors analyse a large Amazon-wide dataset, finding that fast-growing species face greater mortality risk, but that slower-growing individuals within a species are more likely to die, regardless of size.

    Fish production is predicted to decrease with anthropogenic global warming. Here the authors analyse fish fossil assemblages from 62–46 My old deep-sea sediments and instead find a positive correlation between fish production and ocean temperature over geological timescales, which a data-constrained model explains in terms of trophic transfer efficiency and primary production.

    Classical epidemiological approaches have been limited in their ability to formally test hypotheses. Here, Dellicour et al. illustrate how phylodynamic and phylogeographic analyses can be leveraged for hypothesis testing in molecular epidemiology using West Nile virus in North America as an example.

    Correlations between tree species diversity and tree abundance are well established, but the direction of the relationship is unresolved. Here the authors use path models to estimate plausible causal pathways in the diversity-abundance relationship across 23 global forests regions, finding a lack of general support for a positive diversity-abundance relationship, which is prevalent in the most productive lands on Earth only

    The factors that determine whether pathogens co-occur in a host are poorly understood, especially for plant viruses. Here the authors conduct field experiments with the plant Plantago lanceolata and its viruses, showing that viral co-occurrences are driven predominantly by environmental context and host genotype rather than viral interactions.

    The global supply chain and demand for export goods can lead to relocated emissions. Goods produced in China for foreign markets have lead to an increase of domestic non-methane volatile organic compounds emissions by 3.5 million tons in 2013 resulting in potentially an estimated 16,889 premature deaths annually.

    Solar insolation is not equally distributed on the Earth’s surface and such imbalances influence the atmospheric circulation. Here, the authors show that latitudinal insolation gradients synchronized the hydroclimate in the Northern mid-latitudes and the African and South American Monsoons throughout the Holocene.

    The pathogen Batrachochytrium dendrobatidis (BD) associated with widespread amphibian declines is present in Europe but has not consistently caused disease-induced declines in that region. Here, the authors suggest that an endemic strain of BD with low virulence may protect the hosts upon co-infection with more virulent strains.

    Eutrophication has been shown to weaken diversity-stability relationships in grasslands, but it is unclear whether the effect depends on scale. Analysing a globally distributed network of grassland sites, the authors show a positive role of beta diversity and spatial asynchrony as drivers of stability but find that nitrogen enrichment weakens the diversity-stability relationships at different spatial scales.

    Overflow water is an important part of the Atlantic Meridional Overturning Circulation, yet how it reaches the Greenland-Scotland Ridge is not fully known. Here, the authors show that the interior of the Greenland Sea gyre is the primary wintertime source of the densest portion of both Denmark Strait and Faroe Bank Channel overflows.

    Phytoplankton are biogeochemically important but the drivers of their seasonal cycles in the Southern Ocean are poorly resolved. Here the authors use seven years of ARGO float data to measure bloom initiation, decline and termination throughout the Southern Ocean, finding that bloom dynamics are especially sensitive to the coupling between cell division rates and loss processes.

    High-latitude records show large diversity losses of marine plankton, such as radiolarians, with historical climate change. Here, Trubovitz et al. present a low-latitude record spanning the last 10 million years, finding that many high-latitude radiolarians did not shift equatorward but instead went extinct.

    Many models assume a universal carbon use efficiency across forest biomes, in contrast to assumptions of other process-based models. Here the authors analyse forest production efficiency across a wide range of climates to show a positive relationship with annual temperature and precipitation, indicating that ecosystem models are overestimating forest carbon losses under warming.

    Whether or not species—when introduced to a new location—eventually become invasive has been linked to the specices’ capacity to expand its niche. However, here the authors show that the extent of niche shift is smaller in non-invasive than invasive ant species, questioning this established hypothesis.
