Exoskeleton dissolution with mechanoreceptor damage in larval Dungeness crab related to severity of present-day ocean acidification vertical gradients

Highlights • Coastal habitats with the steepest ocean acidification gradients are most detrimental for larval Dungeness crabs. • Severe carapace dissolution was observed in larval Dungeness crabs along the US west coast. • Mechanoreceptors with important sensory and behavioral functions were destabilized. • Dissolution is negatively related to the growth,

Transcriptomic response to decreased pH in adult, larval and juvenile red king crab, Paralithodes camtschaticus, and interactive effects of pH and temperature on juveniles

Ocean warming and acidification are expected to influence the biology of the ecologically and economically important red king crab, Paralithodes camtschaticus. We investigated transcriptome responses of adult, larval and juvenile red king crab to assess sensitivity to reduced pH and elevated temperature. In adults, gill tissue (but not heart or

Quantifying the effects of nutrient enrichment and freshwater mixing on coastal ocean acidification

Jennie E. Rheuban | Scott C. Doney | Daniel C. McCorkle | Rachel W. Jakuba First published: 07 November 2019 https://doi.org/10.1029/2019JC015556 Abstract The U.S. Northeast is vulnerable to ocean and coastal acidification because of low alkalinity freshwater discharge that naturally acidifies the region, and high anthropogenic nutrient loads that lead to
