Elevated CO2 levels predicted to occur by the end of the century can affect the physiology and behaviour of marine fishes. For one important survival mechanism, the response to chemical alarm cues from conspecifics, substantial among-individual variation in the extent of behavioural impairment when exposed to elevated CO2 has been observed in previous studies. Whole […]
The high-latitude oceans are key areas of carbon and heat exchange between the atmosphere and the ocean. As such, they are a focus of both modern oceanographic and palaeoclimate research. However, most palaeoclimate proxies that could provide a long-term perspective are based on calcareous organisms, such as foraminifera, that are scarce or entirely absent in […]
Highlights •Cbln11 mRNA is mainly expressed in the olfactory rosettes and in the gills of European sea bass. •Cbln11 mRNA expression is localized in the non-sensory epithelium of the olfactory rosettes. •Long term exposure to ocean acidification induces a stimulation of cbln11 mRNA expression in the olfactory rosette of European sea bass. •Ocean acidification-induced stimulation of cbln11 […]
Highlights •Elevated CO2 enhanced conchocelis growth regardless of light intensity. •Elevated CO2 enhanced thallus growth at high light but reduced it at low light. •Elevated CO2 did not affect conchocelis respiration rate at either light intensity. •Elevated CO2 increased thallus respiration rate at each light intensity. Abstract Increasing CO2 levels in the surface water of oceans are expected to decrease […]
Highlights •Combined occurrence of hypoxia, acidification and nutrients increased biofilm bacterial diversity and richness •Elevated nutrients, and depleted oxygen and pH levels resulted in different bacterial community composition •Higher abundance of Flavobacteriales, Epsilonproteobacteria and Vibrionales, but less Oceanospirillales and Alteromonadales •Suggests the identities of bacterial groups affected under the ocean trend of pollution, deoxygenation and […]
