Fragile freshwater ecosystems have acted as important sentinels for global environmental change. A detailed understanding of the implications of global change in aquatic ecosystems relies on indicator...
A photosynthetic strategy for coping in a high-light, low-nutrient environment
A photosynthetic strategy in a high-light low-nutrient environment
2014/4/21
Phytoplankton in high-light, low-nutrient ocean environments are challenged with maintaining high photosynthetic efficiency and simultaneously preventing photodamage that results from low levels of el...
Coccolithophore bloom size variation in response to the regional environment of the subarctic North Atlantic
Coccolithophore bloom regional environment subarctic North Atlantic
2014/5/5
Several environmental/physical variables derived from satellite and in situ data sets were used to understand the variability of coccolithophore abundance in the subarctic North Atlantic. The 7-yr (19...
The FeL model of iron acquisition: Nondissociative reduction of ferric complexes in the marine environment
The FeL model of iron acquisition Nondissociative reduction ferric complexes marine environment
2014/5/4
Recently there has been recognition of the importance of reductive processes in the acquisition of iron by microorganisms in marine environments with Fe(III) reduction induced by either membrane-bound...
