Variability in the phytoplankton community of Kavaratti reef ecosystem (northern Indian Ocean) during peak and waning periods of El Niño 2016

El Niño, an interannual climate event characterized by elevated oceanic temperature, is a prime threat for coral reef ecosystems worldwide, owing to their thermal threshold sensitivity. 235 more words

Nutrient co-limited Trichodesmium as nitrogen source or sink in a future ocean

Nitrogen-fixing (N2) cyanobacteria provide bioavailable nitrogen to vast ocean regions but are in turn limited by iron (Fe) and/or phosphorus (P), which may force them to employ alternative nitrogen acquisition strategies. 175 more words

Microbiota - Some history - part 1

Let’s go back in time a little bit. Microbiology is quite a recent science, indeed studying the invisible is quite difficult without any technology. The microscope already shed light on this invisible world, thanks to Antonie van Leeuwenhoek in 1676. 496 more words

Paper out: Are pangenomes adaptive or not?

I have been interested in bacterial pan genomes for some time: apart from acquiring mutations in genes shared between strains, bacteria are able to pick up genes (via several Lateral Gene Transfer processes), duplicate genes and also lose genes. 208 more words

Diversity and stability of coral endolithic microbial communities at a naturally high pCO2 reef

The health and functioning of reef-building corals is dependent on a balanced association with prokaryotic and eukaryotic microbes. The coral skeleton harbours numerous endolithic microbes, but their diversity, ecological roles and responses to environmental stress, including ocean acidification (OA), are not well characterized. 239 more words

Effects of the interaction of ocean acidification, solar radiation, and warming on biogenic dimethylated sulfur compounds cycling in the Changjiang River Estuary

Ocean acidification (OA) affects marine primary productivity and community structure, and therefore may influence the biogeochemical cycles of volatile biogenic dimethyl sulfide (DMS) and its precursor dimethylsulfoniopropionate (DMSP) and photochemical oxidation product dimethyl sulfoxide (DMSO). 246 more words
