An experimental test of climate change effects in northern lakes: Increasing allochthonous organic matter and warming alters autumn primary production
ClimateChange lakes production GPP cDOM
2021/7/26
Climate changes are predicted to influence gross primary production (GPP) of lakes directly through warming and indirectly through increased loads of allochthonous coloured dissolved organic matter (c...
Evidence of Shock Metamorphism Effects in Allochthonous Breccia Deposits from the Colônia Crater, São Paulo, Brazil
Colô nia Crater Polymictic Allochthonous Breccia Shock Metamorphism Effects
2013/3/11
The 3.6 km-diameter Colonia impact crater, centred at 2352'03"S and 4642'27"W, lies 40 km to the south-west of the São Paulo city. The structure was formed on the crystalline basement rocks and d...

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 ...

Linking allochthonous dissolved organic matter boreal lake sediment carbon sequestration The role of light-mediated flocculation
2014/4/21
We measured flocculation of dissolved organic carbon (DOC) in the water from a humic lake (DOC = 14.9 mg C L-1) and from an adjacent mire (DOC = 25.7 mg C L-1), in in situ enclosure experiments with d...
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...
