| Open AccessA fish cartel for Africa
Englander and Costello note that African coastal waters are among the world’s most biologically rich, but African countries earn much less than their peers from selling access to foreign fishers. They find forming a “fish cartel" would increase African fish biomass by 16% and profits by 23%.

| Open AccessMelting and defect transitions in FeO up to pressures of Earth’s core-mantle boundary
Multi-technique synchrotron measurements support the viability of solid FeO-rich structures at Earth’s mantle base. An order-disorder transition identified in the iron defect structure of FeO may lead to unique physical properties in the region.

| Open AccessEnhanced subglacial discharge from Antarctica during meltwater pulse 1A
This study presents seawater uranium isotope records based on deep-sea corals from the Drake Passage to track subglacial discharge from the Antarctic Ice Sheet, demonstrating a causal link between enhanced subglacial discharge, retreat of the ice sheet, and the rapid rise in sea levels.

| Open AccessReconciling Southern Ocean fronts equatorward migration with minor Antarctic ice volume change during Miocene cooling
Hou et al. propose, based on dinocysts, clumped isotopes and ice sheet modelling, that during Miocene cooling, the Antarctic ice sheet progressively lowered in height while expanding seawards, to maintain a relatively stable volume.

| Open AccessClimate change beliefs and their correlates in Latin America
The authors map beliefs in climate change and their correlates in Latin America. The study shows skepticism over the existence and anthropogenic origins of climate change to be limited, but identifies a high number of skeptics around the severity of its consequences. Results also show individualistic worldviews to be the most powerful driver of climate change beliefs in the region.

| Open AccessShort-term acidification promotes diverse iron acquisition and conservation mechanisms in upwelling-associated phytoplankton
Coastal upwelling regions are among the most productive marine ecosystems but may be threatened by amplified ocean acidification. Here the authors show from community to molecular levels that phytoplankton in an upwelling region respond to short-term acidification exposure with iron uptake pathways and strategies that reduce cellular iron demand.

| Open AccessCoupled carbon and nitrogen cycling regulates the cnidarian–algal symbiosis
Photosymbioses enable efficient nutrient recycling between heterotrophic and phototrophic organisms. This study shows that nutrient cycling in a cnidarian-algal symbiosis is regulated through resource competition between symbiotic partners. Mutualistic interactions can therefore emerge from mutual exploitation in nutrient–exchange symbioses.
