Nutrition and income from molluscs today imply vulnerability to ocean acidification tomorrow
TLDR
This study examines the possible implications of ocean acidification on mollusc harvests worldwide by examining present production, consumption and export and by relating those data to present and future surface ocean chemistry forecast by a coupled climate-ocean model.
To brood or not to brood: Are marine invertebrates that protect their offspring more resilient to ocean acidification?
TLDR
These findings are the first to formally validate the hypothesis that species with life history strategies linked to parental care are more protected in an acidifying ocean compared to their relatives employing broadcast spawning and pelagic larval development.
Interpretation and design of ocean acidification experiments in upwelling systems in the context of carbonate chemistry co-variation with temperature and oxygen

Host-associated microbiomes drive structure and function of marine ecosystems
TLDR
Advances in research will help predict responses of species, communities, and ecosystems to stressors driven by human activity and inform future management strategies, and outline research priorities to strengthen current knowledge of host–microbiome interactions.
Oxygen‐mediated plasticity confers hypoxia tolerance in a corallivorous polychaete
TLDR
Exposure to low DO resulted in worms regenerating significantly larger gills compared to worms under normoxia, which indicates that oxygen‐mediated plasticity in both gill morphology and physiology may confer tolerance to increasingly frequent and severe hypoxia in one important coral predator associated with reef decline.
Multi-stressor Extremes Found on a Tropical Coral Reef Impair Performance
TLDR
A strong relationship between high temperatures, low dissolved oxygen (DO), and low pH in and around a tropical bay is documented and results show that short, 2 h exposures to the temperature and DO extremes that are already experienced periodically by these animals have measurable detrimental effects on their performance.
An in situ assessment of local adaptation in a calcifying polychaete from a shallow CO 2 vent system
TLDR
The data suggest that, for Simplaria and possibly other calcifiers, neither local adaptations nor sufficient phenotypic plasticity levels appear to suffice in order to compensate for the negative impacts of OA on long‐term survival.
Hypoxia from depth shocks shallow tropical reef animals
Rapid ecosystem-scale consequences of acute deoxygenation on a Caribbean coral reef
TLDR
The decoupling of ecological trajectories among these major functional groups following an acute event emphasizes the need to incorporate deoxygenation as an emerging stressor into coral reef research and management plans to combat escalating threats to reef persistence.
