The microbiome of the octocoral Lobophytum pauciflorum: minor differences between sexes and resilience to short-term stress

Bacteria associated with marine invertebrates are thought to have a range of important roles that benefit the host including production of compounds that may exclude pathogenic microorganisms and recycling of essential nutrients. 177 more words

1.2.1 Prokaryotes have a simple cell structure without compartmentalization

  • pro: before // karyon: nucleus
  • cells can be divided into two main groups:
    • prokaryotes, which are simple cells
    • eukaryotes, cells which are more complex…

Microbiome dynamics in early life stages of the scleractinian coral Acropora gemmifera in response to elevated pCO2

Reef-building corals are complex holobionts, harbouring diverse microorganisms that play essential roles in maintaining coral health. However, microbiome development in early life stages of corals remains poorly understood. 203 more words

Reviews and syntheses: Ice acidification, the effects of ocean acidification on sea ice microbial communities (update)

Sea ice algae, like some coastal and estuarine phytoplankton, are naturally exposed to a wider range of pH and CO2 concentrations than those in open marine seas. 350 more words

Ocean acidification experiments in large-scale mesocosms reveal similar dynamics of dissolved organic matter production and biotransformation

Dissolved organic matter (DOM) represents a major reservoir of carbon in the oceans. Environmental stressors such as ocean acidification (OA) potentially affect DOM production and degradation processes, e.g., phytoplankton exudation or microbial uptake and biotransformation of molecules. 332 more words

Alterations in microbial community composition with increasing fCO2: a mesocosm study in the eastern Baltic Sea (update)

Ocean acidification resulting from the uptake of anthropogenic carbon dioxide (CO2) by the ocean is considered a major threat to marine ecosystems. Here we examined the effects of ocean acidification on microbial community dynamics in the eastern Baltic Sea during the summer of 2012 when inorganic nitrogen and phosphorus were strongly depleted. 184 more words

Genome-wide mutation rate response to pH change in the coral reef pathogen Vibrio shilonii AK1

Recent application of mutation accumulation techniques combined with whole-genome sequencing (MA/WGS) has greatly promoted studies of spontaneous mutation. However, such explorations have rarely been conducted on marine organisms, and it is unclear how marine habitats have influenced genome stability. 187 more words
