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...
Interspecies differences in calcium content and requirement in four freshwater cladocerans explained by biokinetic parameters
Interspecies differences in calcium content in four freshwater cladocerans explained biokinetic parameters
2014/4/17
We tested the hypothesis that cladocerans with higher calcium (Ca) content are more susceptible to Ca limitation by conducting life table experiments using four cladoceran species with contrasting Ca ...
Diel variations in the photosynthetic parameters of Prochlorococcus strain PCC 9511: Combined effects of light and cell cycle
Diel variations photosynthetic parameters Prochlorococcus strain PCC 9511 light and cell cycle
2014/5/9
We examined the mechanisms related to the diel variations in the parameters of the relationship between the rate of carbon fixation of phytoplankton and irradiance (P vs. E curve). Our goal was to und...
Phytoplankton primary production and photosynthetic parameters in reservoirs along a gradient of watershed land use
Phytoplankton primary production photosynthetic parameters reservoirs along a gradient watershed land use
2014/5/20
We investigated how watershed land use (a gradient of agricultural vs. forested land) relates to phytoplankton primary production (PPr) and photosynthetic parameters in 12 reservoirs in Ohio and exami...
Measurement of photosynthetic parameters in benthic organisms in situ using a SCUBA-based fast repetition rate fluorometer
photosynthetic parameters benthic organisms SCUBA-based fast repetition rate fluorometry
2014/6/17
Benthic photoautotrophic organisms significantly contribute to the productivity of shallow tropical coastal ecosystems. However, measurements of photosynthetic light use and dissipation in benthic org...
