Contribution of mycosporine-like amino acids and colored dissolved and particulate matter to sea ice optical properties and ultraviolet attenuation
amino acids colored dissolved
2010/4/16
In the Baltic Sea ice, the spectral absorption coefficients for particulate matter (PM) were about two times
higher at ultraviolet wavelengths than at photosynthetically available radiation (PAR) wav...
Major bacterial contribution to the ocean reservoir of detrital organic carbon and nitrogen
bacterial contribution the ocean reservoir detrital organic carbon nitrogen
2008/4/21
Bacterial biomarkers (D-amino acids and muramic acid) were measured in various organic matter size fractions collected in the North Pacific and North Atlantic, and they were used to quantitatively est...

Bacterial endosymbionts in Asellus aquaticus (Isopoda) and Gammarus pulex (Amphipoda), and their contribution to digestion
Bacterial endosymbionts Asellus aquaticus Gammarus pulex contribution to digestion
2003/5/22
We demonstrate for the first time the presence of bacterial endosymbionts in the midgut glands (hepatopancreas) of the freshwater detritivore Asellus aquaticus (Isopoda), whereas the hepatopancreas of...

Phytoplankton contribution sestonic mass elemental ratios in lakes zooplankton nutrition
2003/5/20
Phytoplankton carbon and particulate organic carbon (POC), nitrogen (PON), and phosphorus (POP) (POC :PON: POP) were analyzed in 109 temperate lakes covering a wide span in productivity and other key ...
Contribution of entrainment and vertical plumes to the winter cascading of cold shelf waters in a deep lake
Contribution of entrainment vertical plumes the winter cascading cold shelf waters deep lake
2002/3/26
Observations made from vertical moorings of thermistors and current meters are used to analyze the relative contribution of the entrainment of overlying water and the cold plumes convecting from the s...
Colony formation in Scenedesmus: No contribution of urea in induction by a lipophilic Daphnia exudate
Colony formation in Scenedesmus No contribution of urea in induction a lipophilic Daphnia exudate
2001/6/10
The common green alga Scenedesmus may respond morphologically to numerous environmental factors. The formation of colonies in Scenedesmus resulting from exposure to grazer (Daphnia) excreta is of part...
Whole-stream metabolism in two montane streams: Contribution of the hyporheic zone
Whole-stream metabolism two montane streams Contribution of the hyporheic zone
2001/5/9
We used whole-stream and benthic chamber methods to measure rates of metabolism and determine the contribution of the hyporheic zone to ecosystem respiration (R) in two streams with differing surface-...
