Microbes and the Dissipation of Energy and Respiration: From Cells to Ecosystems
Energy and Respiration From Cells
2015/7/22
In the year 1974, Larry Pomeroy first proposed that microbes were true movers of energy and nutrients in marine food webs (Pomeroy, 1974). This idea was later formalized as the "microbial loop" (Azam ...

Widespread variability in overnight patterns of ecosystem respiration linked to gradients in dissolved organic matter, residence time, and productivity in a global set of lakes。
Aerobic respiration and hypoxia in the Lower St. Lawrence Estuary: Stableisotope ratios of dissolved oxygen constrain oxygen sink partitioning
Aerobic respiration and hypoxia Lawrence Estuary dissolved oxygen constrain oxygen sink partitioning
2014/4/17
We measured the concentration and the stable isotope ratios of dissolved oxygen in the water column in the Estuary and Gulf of St. Lawrence to determine the relative importance of pelagic and benthic ...
Temperature effect on respiration and photosynthesis of the symbiont-bearing planktonic foraminifera Globigerinoides ruber, Orbulina universa, and Globigerinella siphonifera
respiration photosynthesis Temperature
2014/4/17
Respiration and photosynthesis of the planktonic foraminifera Globigerinoides ruber, Orbulina universa, and
Globigerinella siphonifera and their symbiotic algae were calculated from measured dissolve...
Dissolved organic matter and bacterial production and respiration in the sea-surface microlayer of the open Atlantic and the western Mediterranean Sea
Dissolved organic matter bacterial production respiration the sea-surface microlayer Atlantic the western Mediterranean Sea
2014/4/21
The sea-surface microlayer (SML) is the boundary layer between the ocean and the atmosphere. We measured bacterial production and respiration along with dissolved organic carbon (DOC), nitrogen (DON),...
Production, oxygen respiration rates, and sinking velocity of copepod fecal pellets: Direct measurements of ballasting by opal and calcite
Production oxygen respiration rates sinking velocity copepod fecal pellets Direct measurements ballasting by opal calcite
2014/4/21
Production, oxygen uptake, and sinking velocity of copepod fecal pelletsegested byTemora longicorniswere measured using a nanoflagellate (Rhodomonassp.), a diatom (Thalassiosira weissflogii), or a coc...
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...

Dissolved organic matter bacterial production respiration in the sea-surface microlayer open Atlantic western Mediterranean Sea
2014/4/18
The sea-surface microlayer (SML) is the boundary layer between the ocean and the atmosphere. We measured bacterial production and respiration along with dissolved organic carbon (DOC), nitrogen (DON),...
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 ...
Respiration, calcification, and excretion of the invasive slipper limpet, Crepidula fornicata L.: Implications for carbon, carbonate, and nitrogen fluxes in affected areas
Respiration calcification excretion invasive slipper limpet Crepidula fornicata L. Implications for carbon carbonate nitrogen fluxes
2014/5/5
We measured in situ respiration, calcification, and excretion of the slipper limpet, Crepidula fornicata L., and considered both seasonal variations and individual size, to estimate the effects of thi...
Prokaryotic respiration and production in the meso- and bathypelagic realm of the eastern and western North Atlantic basin
Prokaryotic respiration production in the meso- and bathypelagic realm eastern and western North Atlantic basin
2014/5/4
We measured prokaryotic production and respiration in the major water masses of the North Atlantic down to a depth of ~4,000 m by following the progression of the two branches of North Atlantic Deep W...
Nutrient and light availability regulate the relative contribution of autotrophs and heterotrophs to respiration in freshwater pelagic ecosystems
Nutrient light availability regulate the relative contribution
2014/4/23
In this study, two main hypotheses were addressed. (1) Bacteria contribute proportionally less than autotrophs to
ecosystem respiration as trophic status increases. This hypothesis was examined in a ...
