Iron and copper limitations differently affect growth rates and photosynthetic and physiological parameters of the marine diatom Pseudo-nitzschia delicatissima
Iron and copper limitations differently affect growth rates photosynthetic and physiological parameters marine diatom Pseudo-nitzschia delicatissima
2014/4/2
In ～ 50% of the ocean, iron (Fe) limits phytoplankton growth, including that of the diatom Pseudo-nitzschia. Fe-limited Pseudo-nitzschia spp. may produce the potent neurotoxin domoic acid (DA) to acce...

CO2 the photosynthetic physiology phytoplankton the Gulf of Alaska
2014/4/16
In the high-nutrient, low-chlorophyll waters of the Gulf of Alaska, microcosm manipulation experiments were used to assess the effect of CO2 on growth and primary production under iron-limited and iro...
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...
Carbon dioxide fixation in the dark by photosynthetic bacteria in sulfide-rich stratified lakes with oxic–anoxic interfaces

We measured in situ photosynthesis of benthic microbial mats at various depths in Lake Hoare, a permanently ice-covered lake of the McMurdo Dry Valleys, Antarctica, using oxygen (O2) microelectrodes. ...
Late summer community composition and abundance of photosynthetic picoeukaryotes in Norwegian and Barents seas
Late summer community composition abundance of photosynthetic picoeukaryotes Norwegian and Barents seas
2014/5/13
We investigated marine picoeukaryotic diversity (cells <3 μm) in samples collected in late summer 2002 at the boundary between the Norwegian, Greenland, and Barents Seas. The two main Arctic and Atlan...
