<
2014/4/17
Daphnia pulexandDaphnia pulicariaare cyclically parthenogenetic crustaceans that are distributed widelyin North American freshwaters. Hybrids ofD. pulexandD. pulicariaare common in the wild, where pop...
Effect of Ocean Acidification on the Speciation of Metals in Seawater
Air carbon dioxide water pH value water calcium animals biological process
<
2015/7/6
Increasing atmospheric CO2 over the next 200 years will cause the pH of ocean waters to decrease further. Many recent studies have examined the effect of decreasing pH on calcifying organisms in ocean...
An evaluation of iron bioavailability and speciation in western Lake Superior with the use of combined physical, chemical, and biological assessment

2014/4/22
A chemical equilibrium model was used to predict the solution speciation of dissolved mercury (Hg) in the stratified water column of Offatts Bayou, a subestuary in Galveston Bay, Texas, which undergoe...

<
2014/4/22
The physicochemical speciation of dissolved iron (Fe) across natural dissolved Fe gradients in the oceanic
and shelf domains of the southeastern Bering Sea was examined in surface and subsurface samp...
Distribution and redox speciation of dissolved iron on the European continental margin
Distribution redox speciation dissolved iron the European continental margin
<
2014/4/21
To investigate the biogeochemistry of iron in the waters of the European continental margin, we determined the dissolved iron distribution and redox speciation in filtered (<0.2 μm) open-ocean and she...
Photo-oxidation of dissolved organic matter in river water and its effect on trace element speciation
Photo-oxidation dissolved organic matter in river water trace element speciation
<
2014/5/4
To investigate the effect of photodegradation of fluvial dissolved organic matter (DOM) on dissolved trace element distributions, we performed a 3-week incubation of water from the lower Pearl River (...
Evolutionary animation: How do molecular phylogenies compare to Mayr’s reconstruction of speciation patterns in the sea?
Evolutionary animation molecular phylogenies
<
2015/12/16
ernst Mayr used the geography of closely related species in various
stages of increasing divergence to ‘‘animate’’ the process of geographic, or allopatric, speciation. This approach was applied to a...
Lead and copper speciation in remote mountain lakes

2014/5/9
We determined the chemical speciation of lead and copper in remote mountain and high-latitude lakes at different times of the year, providing background data for regions in Europe least affected by an...

<
2014/5/19
Organic sulfhydryl compounds, or thiols, are ligands that strongly complex class B metals such as Hg and methylmercury (MeHg). We determined the concentration profiles of five low-molecular-weight thi...
A comparison of the speciation and fate of mercury in two contaminated coastal marine ecosystems: The Venice Lagoon (Italy) and Lavaca Bay (Texas)
speciation and fate mercury in two contaminated coastal marine ecosystems Venice Lagoon (Italy) Lavaca Bay (Texas)
