Millions of seahorses a year are traded internationally, with many eventually sold at retail shops as curios, as aquarium pets, and especially for use in traditional medicine. The entire genus is now...
The cycle of waterborne methylmercury (meHg) in Little Rock Lake is characterized by a period of accumulation during summertime (when the lake is warm and open to the atmosphere) and a period of decl...
Rates of denitrification and nitrous oxide (N2 O) formation, and the sources of N2 and N2 O, were examined by the isotope-pairing technique in three U.K. estuaries (Colne, Humber, Conwy), wh...
We investigated the hypothesis that sulfate reduction rather than oxygenic photosynthesis promotes calcication in a hypersaline microbial mat by increasing the ion concentration product: ICP ...
In extreme environments, retention of nutrients within stream ecosystems contributes to the persistence of aquatic biota and continuity of ecosystem function. In the McMurdo Dry Valleys, Antarctica, ...
We measured rates of N2 production through anaerobic NH oxidation with NO (anammox) and denitrification 1 2 4 2 in permanently cold (from 21.78C to 48C) sediments off the east and west coasts...
Chemical recovery of many acidified lakes in North America has been delayed or reversed as a result of interactions between climatic variability (alterations between drought and nondrought perio...
Field data obtained from 18 European estuaries using the isotope pairing technique were analyzed for trends in relationship between activity of benthic microalgae and coupled nitrification–deni...
Water velocities as high as 25 m s21 have been recorded in the surf zone of wave-swept rocky shores—velocities more than twice the phase speed of the breaking waves with which they are associated. H...
