Seawater carbonate chemistry and photosynthetic performance and N2 fixation in the marine cyanobacterium Trichodesmium ...
Effects of changed levels of dissolved O2 and CO2 on marine primary producers are of general concern with respect to ecological effects of ongoing ocean deoxygenation and acidification as well as upwelled seawaters. We investigated the response of the diazotroph Trichodesmium erythraeum IMS 101 afte...
