To brood or not to brood: Are marine invertebrates that protect their offspring more resilient to ocean acidification?

Anthropogenic atmospheric carbon dioxide (CO2) is being absorbed by seawater resulting in increasingly acidic oceans, a process known as ocean acidification (OA). OA is thought to have largely deleterious effects on marine invertebrates, primarily impacting early life stages and consequently, their recruitment and species’ survival. Show More Summary

Reviews and Syntheses: Ocean acidification and its potential impacts on marine ecosystems

Ocean acidification, a complex phenomenon that lowers seawater pH, is the net outcome of several contributions. They include the dissolution of increasing atmospheric CO2 that adds up with dissolved inorganic carbon (dissolved CO2, H2CO3, HCO3?, and CO32?) generated upon mineralization of primary producers (PP) and dissolved organic matter (DOM).

Deducing acidification rates based on short-term time series

We show that, statistically, the simple linear regression (SLR)-determined rate of temporal change in seawater pH (?pH), the so-called acidification rate, can be expressed as a linear combination of a constant (the estimated rate ofShow More Summary

Acid dulls the senses: impaired locomotion and foraging performance in a marine mollusc

The possible impacts of ocean acidification have gained substantial attention for their potential to alter physiological functioning of marine organisms. Less recognized are the present impacts of estuarine acidification, a widespread form of coastal acidification caused by terrestrial runoff and coastal current dynamics. Show More Summary

A fundamental paradigm for coral reef carbonate sediment dissolution

The long-term success of coral reefs depends on a positive balance of calcium carbonate production exceeding dissolution, erosion, and material export. As a result of ocean acidification, coral reefs could transition from net accretion to net erosion owing to decreasing rates of calcification and increasing rates of chemical dissolution and bioerosion. Here, I present a […]

Framework of barrier reefs threatened by ocean acidification

To date, studies of ocean acidification (OA) on coral reefs have focused on organisms rather than communities, and the few community effects that have been addressed have focused on shallow back reef habitats. The effects of OA on outer barrier reefs, which are the most striking of coral reef habitats and are functionally and physically […]

Persistence of positive carryover effects in the oyster, Saccostrea glomerata, following transgenerational exposure to ocean acidification

Ocean acidification (OA) is predicted to have widespread implications for marine organisms, yet the capacity for species to acclimate or adapt over this century remains unknown. Recent transgenerational studies have shown that for some marine species, exposure of adults to OA can facilitate positive carryover effects to their larval and juvenile offspring that help them […]

Functional properties of hemoglobin during the adaptation of fish to low environmental pH

  The dependence of the resistance of fish to acidification on the functional properties of hemoglobin has been studied in 21 species (nine families) of freshwater, marine, and anadromous fish. A direct correlation between the fish tolerance to low pH and the value of the Bohr effect has been revealed for the first time. On […]

Ocean acidification threatens shellfish hatcheries (text & audio)

New research paints an unsettling picture of the future of shellfish in coastal Alaska. The effects of ocean acidification are worsening and could mean the end of hatcheries in the next 25 years if costly mitigation efforts aren’t put in place. Two-thousand forty – that’s the year put forward by researchers in the ongoing study. “It […]

LEMONSEA – Association de lutte contre l’acidification des océans (in French)

LEMONSEA est une association dont l’objet est de sensibiliser le grand public aux enjeux soulevés par l’acidification des océans. Plus précisément, elle a vocation à: créer des outils pédagogiques innovants en vue de favoriser la vulgarisation scientifique sur les enjeux liés à l’acidification des océans; contribuer à la diffusion des savoirs en partageant du contenu […]
