Meta-analysis reveals negative yet variable effects of ocean acidification on marine organisms

Response to technical comment on `meta-analysis reveals negative yet variable effects of ocean acidification on marine organisms'.

It has been proposed that crustaceans should be excluded from a comparison of biological responses to ocean acidification among organisms with different calcium carbonate (CaCO3 ) forms in their calcified structures. We re-analysed our data without crustaceans and found high variation in organismal responses within CaCO3 categories. We conclude that the CaCO3 polymorph alone does not predict se...

Meta-analysis reveals complex marine biological responses to the interactive effects of ocean acidification and warming

Ocean acidification and warming are considered two of the greatest threats to marine biodiversity, yet the combined effect of these stressors on marine organisms remains largely unclear. Using a meta-analytical approach, we assessed the biological responses of marine organisms to the effects of ocean acidification and warming in isolation and combination. As expected biological responses varied...

Meta-analysis reveals taxon- and life stage-dependent effects of ocean acidification on marine calcifier feeding performance

Using functional genomics to explore the effects of ocean acidification on calcifying marine organisms

As the research community attempts to forecast the effects of ocean acidification on marine ecosystems, a critical element is a clear understanding of the effects of ocean acidification on an individual organism’s physiology. This article explores how the use of genomics-based tools that measure gene expression — DNA microarrays and quantitative PCR — can assist in this effort and reveal aspect...

Early detection of ocean acidification effects on marine calcification

[1] Ocean acidification is likely to impact calcification rates in many pelagic organisms, which may in turn cause significant changes in marine ecosystem structure. We examine effects of changes in marine CaCO3 production on total alkalinity (TA) in the ocean using the global biogeochemical ocean model HAMOCC. We test a variety of future calcification scenarios because experimental studies wit...
