Living in transparent lakes: Low food P:C ratio decreases antioxidant response to ultraviolet radiation in Daphnia
Living in transparent lakes Low food P:C ratio decreases antioxidant response ultraviolet radiation in Daphnia
2014/4/21
We experimentally tested the effect of food quality (phosphorus [P] : carbon [C] ratio) on the response of antioxidant enzymes to ultraviolet radiation (UVR) in Daphnia commutata fed with Chlamydomona...
Long-term photochemical and microbial decomposition of wetland-derived dissolved organic matter with alteration of13 C:12C mass ratio
photochemical microbial decomposition wetland-derived dissolved organic matter alteration of13 C:12C mass ratio
2014/4/18
We investigated the long-term photochemical and microbial decomposition of biologically recalcitrant humiclike dissolved organic matter (DOM) leached from a vascular wetland plant, the common rush (Ju...

Phylogenetic diversity in cadmium : phosphorus ratio regulation by marine phytoplankton
Phylogenetic diversity cadmium phosphorus ratio regulation marine phytoplankton
2014/4/22
We examined the effect of irradiance and growth rate on cadmium : phosphorus ratio in five species of phytoplankton representing four different phylogenetic groups to determine the relative importance...
Investigation of the optical backscattering to scattering ratio of marine particles in relation to their biogeochemical composition in the eastern English Channel and southern North Sea
Investigation of the optical backscattering scattering ratio of marine particles relation to their biogeochemical composition eastern English Channel and southern North Sea
2014/4/23
The variability of the backscattering to scattering ratio of marine particles, bbp : bp, is examined from in situ measurements performed during the spring and early summer of 2004 in the eastern Engli...
Effects of the depth to coral height ratio on drag coefficients for unidirectional flow over coral
Effects of the depth coral height ratio drag coefficients unidirectional flow over coral
2014/5/4
We investigated the effects of the ratio of water depth (H) to coral height (h) on the drag coefficient (Cd) for unidirectional flow over the coral species Porites compressa. Cd, measured in a laborat...
Effects of dissolved carbon dioxide, zinc, and manganese on the cadmium to phosphorus ratio in natural phytoplankton assemblages
Effects of dissolved carbon dioxide, zinc, and manganese the cadmium to phosphorus ratio natural phytoplankton assemblages
2014/5/9
We report the results of a field study, in productive waters off California, of the factors that control the particulate cadmium (Cd) : phosphorus (P) composition of natural assemblages of marine phyt...
Effect of iron limitation on the cadmium to phosphorus ratio of natural phytoplankton assemblages from the Southern Ocean
iron limitation cadmium to phosphorus ratio natural phytoplankton assemblages Southern Ocean
2014/5/20
There is considerable interest in the biogeochemical cycling of cadmium (Cd) and phosphate (PO4) in surface waters, driven in part by the ongoing development of a paleonutrient proxy that utilizes Cd ...
The influence of food quality (P:C ratio) on RNA:DNA ratio and somatic growth rate of Daphnia
The influence of food quality P:C ratio RNA:DNA ratio somatic growth rate of Daphnia
2014/5/26
Growth experiments with juvenile Daphnia galeata were performed to investigate how fast their RNA:DNA ratio responds to changes in food quality, the relationship between RNA:DNA ratio and somatic grow...
Non-Redfield C:N ratio of transparent exopolymeric particles in the northwestern Mediterranean Sea
Non-Redfield C:N ratio transparent exopolymer particles northwestern Mediterranean Sea
2014/6/10
The stoichiometric model of Redfield, which describes the elemental composition of marine organic matter, is generally used to link the production of new organic matter to the uptake of nitrate. The R...
