The tip of the tail: molecular identification of seahorses for sale in apothecary shops and curio stores in California
Molecular forensics
2015/12/11
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 methylmercury cycle in Little Rock Lake during experimental acidification and recovery
The methylmercury cycle Little Rock Lake
2014/4/23
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...
Sources of nitrogen used for denitrification and nitrous oxide formation in sediments of the hypernutrified Colne, the nutrified Humber, and the oligotrophic Conwy estuaries, United Kingdom
denitrifi cation nitrous oxide
2014/4/30
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...
Photosynthesis-controlled calcification in a hypersaline microbial mat
Photosynthesis-controlled calcifi cation hypersaline microbial mat
2014/5/13
We investigated the hypothesis that sulfate reduction rather than oxygenic photosynthesis promotes calcification
in a hypersaline microbial mat by increasing the ion concentration product: ICP ...
Denitrification and hydrologic transient storage in a glacial meltwater stream, McMurdo Dry Valleys, Antarctica
Denitrifi cation hydrologic transient storage
2014/5/19
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, ...
Denitrification and anammox activity in Arctic marine sediments
Denitrifi cation anammox activity
2014/5/19
We measured rates of N2
production through anaerobic NH oxidation with NO (anammox) and denitrification 1 2

in permanently cold (from 21.78C to 48C) sediments off the east and west coasts...
Effects of drought-induced acidification on diatom communities in acid-sensitive Ontario lakes
drought-induced acidifi cation acid-sensitive Ontario lakes
2014/5/21
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...
Coupled nitrification–denitrification inautotrophic c and heterotrophic estuarine sediments: On the influence of benthic microalgae
Coupled nitrifi cation–denitrifi cation autotrophic
2014/5/20
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...
Extreme water velocities: Topographical amplification of wave-induced flow in the surf zone of rocky shores
Extreme water velocities wave-induced fl ow
2014/5/20
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...
