dissolved organic matter dynamics A review
2014/4/17
The biochemical composition of dissolved organic matter (DOM) strongly influences its biogeochemical role in
freshwater ecosystems, yet DOM composition measurements are not routinely incorporated int...
Bioavailability and export of dissolved organic matter from a tropical river during base- and stormflow conditions
Bioavailability base- stormflow conditions
2014/4/18
Concentrations, bioavailability, and export of dissolved organic matter (DOM), particulate organic matter
(POM), and nutrients from the Wailuku River, Hawai‘i, U.S.A., were examined under base- and s...
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...
Accumulation of prokaryotic remains during organic matter diagenesis in surface sediments off Peru
Accumulation of prokaryotic organic matter diagenesis
2014/4/18
Bacterial biomarkers (D-amino acids and muramic acid) were investigated in surface sediments (0–1 cm) at 22
stations in the Peru margin. Concentrations were used to quantitatively estimate the relati...
Organic matter diagenesis and bacterial contributions to detrital carbon and nitrogen in the Amazon River system
Organic matter diagenesis bacterial contributions
2014/4/18
Amino sugars and amino acids, including the bacterial biomarkers muramic acid and D-amino acids, were
measured to investigate the diagenetic alterations of and microbial contributions to detrital org...
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 ...
Effects of climate on organic carbon and the ratio of planktonic to benthic primary producers in a subarctic lake during the past 45 years
organic carbon benthic primary producers
2014/4/17
The effects of climatic variables on lake-water total organic carbon (TOC) concentrations and benthic and
pelagic primary producers during the past 45 yr were assessed using the sediment records of t...
