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...
Benthic biogeochemical cycling, nutrient stoichiometry, and carbon and nitrogen mass balances in a eutrophic freshwater bay
Benthic biogeochemical cycling nutrient stoichiometry
2014/4/18
Green Bay, while representing only ,7% of the surface area and ,1.4% of the volume of Lake Michigan,
contains one-third of the watershed of the lake, and receives approximately one-third of the total...
High intraspecific variability in carbon and nitrogen stable isotope ratios of lake chironomid larvae
High intraspecifi c variability nitrogen stable isotope
2014/5/14
Stable isotope analyses of chironomid trophic interactions have recently indicated the potential importance of
isotopically light biogenic methane as a carbon source. Mass balance of isotope ratios s...
Effect of temperature on diatom volume, growth rate, and carbon and nitrogen content: Reconsidering some paradigms
iatom volume growth rate carbon
2014/5/30
We examined the response of diatoms to naturally experienced temperatures and tested these hypotheses: (1)
diatoms follow the rule that organism size decreases with increasing temperature; (2) diatom...
Microbial degradation of organic carbon and nitrogen on diatom aggregates
organic carbon nitrogen

The major pathways of transformation of particulate organic matter by heterotrophic bacteria are respiration and
production of new biomass. Until today only a limited number of studies have measured ...
