A U.S. National Science Foundation-funded study led by University of Hawai‘i at Mānoa researchers has revealed that diversity in Hawaiian corals is likely driven by co-evolution among t...
Daphnia pulexandDaphnia pulicariaare cyclically parthenogenetic crustaceans that are distributed widelyin North American freshwaters. Hybrids ofD. pulexandD. pulicariaare common in the wild, where pop...
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 iron-dependent cyanobacterial bioreporter (Synechococcus strain KAS101) was used in unison with size-fractionated iron content (>0.45, <0.45, <0.02 μm), and chemical characterization of iron comple...
An iron-dependent cyanobacterial bioreporter (Synechococcus strain KAS101) was used in unison with sizefractionated iron content (.0.45, ,0.45, ,0.02 mm), and chemical characterization of iron complex...
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...
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...
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...
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 (...
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...
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...
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...
We compared the speciation of Hg in two estuaries, Lavaca Bay (Texas) and the Venice Lagoon (Italy). Both are large, shallow embayments that are contaminated by direct discharges from mercury-cell chl...
The hydrophobicity and particle–water interactions of cadmium (Cd) and zinc (Zn) in an ‘‘organic-poor’’ estuary (Plym, United Kingdom) and an ‘‘organic-rich’’ estuary (Beaulieu, United Kingdom) have ...
The rich species diversity of the marine Indo-West Pacific (IWP) has been explained largely on the basis of historical observation of large-scale diversity gradients. Careful study of divergence amon...
