| Open AccessTowards establishing a fungal economics spectrum in soil saprobic fungi
Challenges in obtaining empirical trait data hinder the development of trait-based frameworks for soil microbes. Here, the authors analyse traits of saprobic fungal isolates from a grassland site to propose a fungal economics spectrum, suggesting a general trait framework for soil fungi.

The effectiveness of community-based land protection compared to traditional top-down protection is debated. Here, the authors show that both community-managed forests and traditional protected areas in Madagascar experienced deforestation during a political crisis but the former were especially vulnerable in the post-crisis period.

| Open AccessHidden impacts of ocean warming and acidification on biological responses of marine animals revealed through meta-analysis
Climate change effects on animals are typically measured as decreases or increases in performance, compared to controls. Because both directions can have cascading effects at the ecosystem level, this study conducts a meta-analysis testing for deviations in biological responses using absolute rather than relative changes, showing that impacts on marine animals might have been largely underestimated.

| Open AccessSystematic review of the uncertainty of coral reef futures under climate change
Global warming targets are considered inadequate to protect coral reefs, but this prognosis is based on models with similar approaches. This systematic review of studies that project coral responses to climate change found that divergent modelling methodologies had discrepancies in coral reef outcomes, and that those used for climate change syntheses may project more severe consequences than other methods.

This study shows that a multitrophic community model jointly recapitulates diel rhythms in abundances of Prochlorococcus picocyanobacteria, as well as viral infection, viral abundances and grazer abundances. Model-data integration implies that grazing predominantly controls Prochlorococcus abundances in surface waters of the North Pacific Subtropical Gyre, despite high viral densities.
