Climate change boosts cyanobacteria

Nature Reviews Microbiology volume 16, pages 122–123 (2018)Cite this article

Subjects

To study the effects of climate change, Ullah et al. set up 12 mesocosms that each harboured three different marine habitats — rocky reefs, seagrass and open sand — and exposed them to increased temperatures, acidification due to increased CO2 or both over 6 months. Temperature and CO2 were set at levels that are predicted to be reached at the end of this century if greenhouse gas emissions continue at current rates. All habitats and organisms used in the mesocosms were collected off the Australian Gulf St Vincent and ranged from phytoplankton and microzooplankton to crustaceans and large fish, and the mesocosms were provided with unfiltered sea water.

∼80% of the energy flow from primary production was diverted to detritus at the bottom of the food web
