Meiosis is the process of copying, pairing and separating chromosomes to make reproductive cells such as eggs and sperm. Organisms that reproduce asexually use a form of cell division called mitosis to reproduce. 555 more words

Climate-driven change in a Baltic Sea summer microplanktonic community – desalination play a more important role than ocean acidification

Scenario modeling suggests that the Baltic Sea, one of the largest brackish-water bodies in the world, could expect increased precipitation (decreased salinity) and increased concentration of atmospheric CO2 over the next 100 years. 280 more words


Eutrophication accelerates carbonate dissolution under high pCO2 condition in coral reef ecosystem

Incubation experiments were carried out to determine the effect of eutrophication on carbonate dissolution under high pCO2 (partial pressure of carbon dioxide) condition in coral reef ecosystem at Sesoko Island, Okinawa, Japan. 184 more words


Effect of ocean acidification and elevated fCO2 on trace gas production by a Baltic Sea summer phytoplankton community (update)

The Baltic Sea is a unique environment as the largest body of brackish water in the world. Acidification of the surface oceans due to absorption of anthropogenic CO2 emissions is an additional stressor facing the pelagic community of the already challenging Baltic Sea. 351 more words


Enhanced CO2 concentrations change the structure of Antarctic marine microbial communities

The impacts of anthropogenic enhancement of the partial pressure of carbon dioxide (pCO2) on marine organisms remain unclear, especially in Antarctic waters, which are predicted to be amongst the earliest and most severely affected by the consequent changes in ocean chemistry. 231 more words


Multi-taxon activity profiling reveals differential microbial response to reduced seawater pH and oil pollution

There is growing concern that predicted changes to global ocean chemistry will interact with anthropogenic pollution to significantly alter marine microbial composition and function. However, knowledge of the compounding effects of climate change stressors and anthropogenic pollution is limited. 275 more words


Assessing approaches to determine the effect of ocean acidification on bacterial processes (update)

Bacterial extracellular enzymes play a significant role in the degradation of labile organic matter and nutrient availability in the open ocean. Although bacterial production and extracellular enzymes may be affected by ocean acidification, few studies to date have considered the methodology used to measure enzyme activity and bacterial processes. 148 more words
