Eutrophication and acidification: Do they induce changes in the dissolved organic matter dynamics in the coastal Mediterranean Sea?

Two mesocosms experiments were conducted in winter 2010 and summer 2011 to examine how increased pCO2 and/or nutrient concentrations potentially perturbate dissolved organic matter dynamics in natural microbial assemblages. 245 more words


Warming and acidification-mediated resilience to bacterial infection determine mortality of early Ostrea edulis life stages

The combined effects of temperature and seawater acidification were investigated across larval stages of the European flat oyster Ostrea edulis, from veliger sizes released by gravid individuals to spat. 252 more words


Effect of elevated CO2 concentration on microalgal communities in Antarctic pack ice

Increased anthropogenic CO2 emissions are causing changes to oceanic pH and CO2 concentrations that will impact many marine organisms, including microalgae. Phytoplankton taxa have shown mixed responses to these changes with some doing well while others have been adversely affected. 237 more words


Carbon Capture and Storage (CCS): Risk assessment focused on marine bacteria

Carbon capture and storage (CCS) is one of the options to mitigate the negative effects of the climate change. However, this strategy may have associated some risks such as CO2 leakages due to an escape from the reservoir. 191 more words


Shallow-water hydrothermal vents in the Azores (Portugal)

The impact of global warming has been a major issue in recent years and will continue increasing in the future. Knowledge about the effects of ocean acidification on marine organisms and communities is crucial to efficient management. 324 more words


Implications of ocean acidification for marine microorganisms from the free-living to the host-associated

Anthropogenic CO2 emissions are causing oceans to become more acidic, with consequences for all marine life including microorganisms. Studies reveal that from the microbes that occupy the open ocean to those intimately associated with their invertebrate hosts, changing ocean chemistry will alter the critical functions of these important organisms. 246 more words



The cell is very diverse.    If an object has no cell it is not alive and anything smaller than a cell is not alive because cells are the most basic units of life.  225 more words
