CO2 in fresh waters: photosynthesis, ecology & global carbon-cycles


Prof Stephen Maberly


Abstract
Inorganic carbon is an essential resource for photosynthetic organisms but is extremely variable temporally, and spatially within and among lakes. At the same time, different photosynthetic organisms differ in the extent to which they can exploit the inorganic carbon reserves for photosynthesis, with capable species using carbon dioxide concentrating mechanisms. Finally, although lakes cover less than 4% of the global non-glaciated land surface, they are biogeochemical hotspots and an important part of the global carbon cycle. This talk will explore the variability in reserves of inorganic carbon, their possible consequences for the ecological distribution in space and time of freshwater phytoplankton and macrophytes and the processes by which lakes emit greenhouse gases to the atmosphere.



Hope to see many of you - everyone most welcome to attend!
