Food supply confers calcifiers resistance to ocean acidification
Invasion of ocean surface waters by anthropogenic CO2 emitted to the atmosphere is expected to reduce surface seawater pH to 7.8 by the end of this century compromising marine calcifiers. A broad range of biological and mineralogical mechanisms allow marine calcifiers to cope with ocean acidification, however these mechanisms are energetically demanding which affect other biological processes (...
متن کاملEffects of ocean-acidification-induced morphological changes on larval swimming and feeding.
Reduction in global ocean pH due to the uptake of increased atmospheric CO(2) is expected to negatively affect calcifying organisms, including the planktonic larval stages of many marine invertebrates. Planktonic larvae play crucial roles in the benthic-pelagic life cycle of marine organisms by connecting and sustaining existing populations and colonizing new habitats. Calcified larvae are typi...
متن کاملLarval development of the barnacle Amphibalanus improvisus responds variably but robustly to near-future ocean acidification
Increasing atmospheric CO2 decreases seawater pH in a phenomenon known as ocean acidification. In two separate experiments we found that larval development of the barnacle Amphibalanus (Balanus) improvisuswas not significantly affected by the level of reduced pH that has been projected for the next 150 years. After 3 and 6 days of incubation, we found no consistent effects of reduced pHondevelo...
متن کاملBiomarker response of climate change-induced ocean acidification and hypercapnia studies on brachyurian crab Portunus pelagicus
A laboratory level microcosm analysis of the impacts of ocean acidification on the environmental stress biomarkers in Portunus pelagicus (Linneaus 1758)exposed to a series of pH regimes expected in the year 2100 (pH 7.5 and 7.0) and leakage from a sub-seabed carbon dioxide storage site (pH 6.5 - 5.5) was carried out. Levels of the antioxidant enzyme catalase, the phase II detoxificatio...
متن کاملDigestion in sea urchin larvae impaired under ocean acidification
Larval stages are considered as the weakest link when a species is exposed to challenging environmental changes1,2. Reduced rates of growth and development in larval stages of calcifying invertebrates in response to ocean acidification might be caused by energetic limitations3. So far no information exists on how ocean acidification affects digestive processes in marine larval stages. Here we r...
