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...
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...
Effects of warming on benthic communities in a boreal lake: Implications of climate change
Effects of warming benthic communities boreal lake: Implications climate change
2014/5/13
We experimentally warmed a series of shallow enclosures by 4.5°C and measured responses of the epilithon (biofilm on rocky surfaces) and invertebrates. Maximum rates of net photosynthesis increased by...
Biological and photochemical production of dissolved gaseous mercury in a boreal lake
Biological and photochemical production dissolved gaseous mercury boreal lake
2014/5/19
We used in situ experiments and measured depth profiles of dissolved gaseous mercury (DGM) to investigate the relative contribution of photochemical versus biological processes on the production of DG...
