Ocean acidification (OA), a consequence of increased global carbon dioxide (CO2) emissions, is considered a major threat to marine ecosystems. Its effects on bacterioplankton activity, diversity and community composition have received considerable attention. However, the direct impact of OA on heterotrophic bacterioplankton is often masked by the significant response of phytoplankton due to the close […]
In many scientific studies, the underlying data-generating process is unknown and multiple statistical models are considered to describe it. For example, in a factorial experiment we might consider models involving just main effects, as well as those that include interactions. Model-averaging is a commonly-used statistical technique to allow for model uncertainty in parameter estimation. In […]
The Ulva prolifera green tides in the Yellow Sea, China, which have been occurring since 2007 are a serious environmental problem attracting worldwide attention. Despite extensive research, the outbreak mechanisms have not been fully understood. Comprehensive analysis of anthropogenic and natural biotic and abiotic factors reveals that human activities, regional physicochemical conditions and algal physiological characteristics as […]
Highlights Stimulation of the primary production and calcification of corallines by grazing Different response of maerl between winter and summer conditions High vulnerability of corallines to ocean acidification in the presence of grazers Abstract Coralline algae are expected to be adversely impacted by ocean acidification and warming. Most research on these algae has involved experiments […]
We compare physiological responses of the crustacean copepod Calanus pacificus and pelagic pteropod mollusk Limacina helicina to ocean temperatures and pH by measuring biomarkers of oxidative stress, antioxidant defences, and the activity of the respiratory electron transport system in organisms collected on the 2016 West Coast Ocean Acidification cruise in the California Current System. Copepods […]
40%: The increase in atmospheric carbon dioxide (CO2) levels since the start of the industrial revolution.
