Hydrogen peroxide dynamics in an agricultural headwater stream: Evidence for significant nonphotochemical production
Hydrogen peroxide dynamics nonphotochemical production
2014/4/2
Hydrogen peroxide (H2O2
) plays key roles in aquatic systems, including metal redox cycling and degradation
of organic matter into bioavailable forms. Abiotic photoproduction, via photo-oxidation of...
Many Caribbean coral reefs have either stopped growing or are on the threshold of starting to erode with potential impacts to people, according to research from The University of Queensland (UQ).
Experimental evidence of a low-oxygen refuge for large zooplankton
Experimental evidence a low-oxygen refuge large zooplankton
2014/4/4
We tested the hypothesis that hypoxic zones in the metalimnion and hypolimnion of lakes can provide a refuge against fish predation for large zooplankton. Experiments were run in a large indoor mesoco...
