Constrained microbial processing of allochthonous organic carbon in boreal lake sediments
Constrained microbial processing allochthonous organic carbon boreal lake sediments
2014/4/2
We investigated sediment bacterial metabolism in eight lakes with different inputs of allochthonous and autochthonous organic carbon in south-central Sweden. Sediment bacterial production, mineralizat...
Aging of allochthonous organic carbon regulates bacterial production in unproductive boreal lakes
allochthonous organic carbo production in unproductive
2014/4/18
We calculated average aquatic dissolved organic carbon (DOC) age (the time span from soil discharge to
observation) in water from the inlets and outlets of two unproductive Swedish lakes at different...
Autochthonous and allochthonous contributions to mesozooplankton diet in a tidal river and estuary: Integrating carbon isotope and fatty acid constraints
Autochthonous allochthonous contributions
2014/4/17
We examined the carbon sources used by bacteria and mesozooplankton in the Scheldt River and estuary
(Belgium, The Netherlands) using a combined stable isotope and fatty acid composition approach. Wa...
Microbially induced flocculation of allochthonous dissolved organic carbon in lakes
Microbially induced allochthonous dissolved organic carbon
2014/4/17
The flocculation of allochthonous dissolved organic carbon (DOC) in lakes was investigated in a series of
laboratory experiments. Flocculation was enhanced by increased temperatures, and addition of ...
Winter respiration of allochthonous and autochthonous organic carbon ina subarctic clear-water lake
Winter respiration allochthonous autochthonous organic carbon subarctic clear-water lake
2014/4/21
We studied a small subarctic lake to assess the magnitude of winter respiration and the organic carbon (OC) source for this respiration. The concentration and stable isotopic composition (d13 C) of di...
Linking allochthonous dissolved organic matter and boreal lake sedimentcarbon sequestration: The role of light-mediated flocculation
allochthonous dissolved organic matter boreal lake sedimentcarbon sequestration light-mediated flocculation
2014/4/18
We measured flocculation of dissolved organic carbon (DOC) in the water from a humic lake (DOC5 14.9 mg C L21) and from an adjacent mire (DOC 525.7 mg C L21), in in situ enclosure experiments with dif...
Respiration of allochthonous organic carbon in unproductive forest lakes determined by the Keeling plot method
Respiration of allochthonous organic carbon unproductive forest lakes determined the Keeling plot method
2014/4/23
We carried out short-term (2 d) experiments in nine unproductive lakes in northern Sweden in order to investigate organic carbon sources supporting lake water respiration. Surface water was incubated ...
Archaea in particle-rich waters of the Beaufort Shelf and Franklin Bay, Canadian Arctic: Clues to an allochthonous origin?
particle-rich waters Beaufort Shelf Franklin Bay
2014/4/23
We used 49,6-diamidino-2-phenylindole (DAPI) staining and fluorescent in situ hybridization to examine total bacterioplankton and archaeal distributions in surface waters and in deeper nepheloid...
Autochthonous versus allochthonous carbon sources to bacteria: Results from whole-lake 13C addition experiments
Autochthonous allochthonous carbon sources bacteria whole-lake 13C
2014/5/14
Organic substrates for pelagic bacteria are derived from dissolved organic carbon (DOC) in the water column. DOC is a heterogeneous mixture of molecules, some of which are imported from the watershed ...
Control of zooplankton dependence on allochthonous organic carbon in humic and clear-water lakes in northern Sweden
zooplankton dependence allochthonous organic carbon
2014/5/20
We compared the stable carbon isotopic composition (d
13
C) of crustacean zooplankton with that of potential
carbon sources in 15 lakes in northern Sweden with different dissolved organic carbon (D...
Whole-lake mineralization of allochthonous and autochthonous organic carbon in a large humic lake (Ortrasket, N. Sweden)
Whole-lake mineralization allochthonous and autochthonous organic carbon a large humic lake
2014/6/10
Organic carbon mineralization was studied in a large humic lake (Lake Ortrasket) in northern Sweden during a well-defined summer stratification period following high water flow during snowmelt. Severa...
