The formation of aggregates in coral reef waters under elevated concentrations of dissolved inorganic and organic carbon: A mesocosm approach

The transformation of dissolved organic carbon (DOC) to particulate organic carbon is the major mechanism through which large sinking organic particles are formed in aquatic systems. 273 more words


Modeling the role of pH on Baltic Sea cyanobacteria

We simulate pH-dependent growth of cyanobacteria with an ecosystem model for the central Baltic Sea. Four model components—a life cycle model of cyanobacteria, a biogeochemical model, a carbonate chemistry model and a water column model—are coupled via the framework for aquatic biogeochemical models. 110 more words


The Cell

Cells are the smallest unit of life that can replicate independently, and are often called the “building blocks of life”. The study of cells is called cell biology. 871 more words


Seagrass biofilm communities at a naturally CO2-rich vent

Seagrass meadows are a crucial component of tropical marine reef ecosystems. Seagrass plants are colonized by a multitude of epiphytic organisms that contribute to broadening the ecological role of seagrasses. 184 more words


The effect of CO2 and temperature change on phytoplankton and benthic algae - a mesocosm study

By the end of this century, the expected atmospheric CO2 concentration will reach 800~1000 ppm. Phytoplankton and benthic algae are the primary production in the ocean, but the effects of CO2 and temperature on the algae is inconclusive. 159 more words


Metagenomics reveals planktonic bacterial community shifts across a natural CO2 gradient in the Mediterranean Sea

Bacterial communities at a CO2 vent (pH 6.7) were compared with those at control (pH 8.0) and transition sites (pH 7.6) using 16S rRNA metagenomics. … 68 more words


Warming and acidification promote cyanobacterial dominance in turf algal assemblages

As marine ecosystems are predicted to be facing increases in both temperature and CO2 levels, resulting in increased acidity, scientific research is attempting to predict the effect that the altered environmental conditions will have on species, communities and, ultimately, ecosystems. 233 more words
