Combined effects of different CO2 levels and N sources on the diazotrophic cy...
To predict effects of climate change and possible feedbacks, it is crucial to understand the mechanisms behind CO2 responses of biogeochemically relevant phytoplankton species.... -
Diversity of ocean acidification effects on marine N2 fixers
Considering the important role of N2 fixation for primary productivity and CO2 sequestration, it is crucial to assess the response of diazotrophs to ocean acidification.... -
Impacts of groundwater discharge at Myora Springs (North Stradbroke Island, A...
Myora Springs is one of many groundwater discharge sites on North Stradbroke Island (Queensland, Australia). Here spring waters emerge from wetland forests to join Moreton Bay,... -
Direct linkage between dimethyl sulfide production and microzooplankton grazi...
Oceanic dimethyl sulfide (DMS) is the enzymatic cleavage product of the algal metabolite dimethylsulfoniopropionate (DMSP) and is the most abundant form of sulfur released into... -
Trichodesmium's strategies to alleviate phosphorus limitation in the future a...
Global warming may exacerbate inorganic nutrient limitation, including phosphorus (P), in the surface-waters of tropical oceans that are home to extensive blooms of the marine... -
Acid-base regulation in the Dungeness crab (Metacarcinus magister)
Homeostatic regulation allows organisms to secure basic physiological processes in a varying environment. To counteract fluctuations in ambient carbonate system speciation due... -
Increased feeding and nutrient excretion of adult antarctic krill, Euphausia ...
Ocean acidification has a wide-ranging potential for impacting the physiology and metabolism of zooplankton. Sufficiently elevated CO2 concentrations can alter internal... -
Seawater carbonate chemistry, biomass and metabolic rates (leucine incorporat...
Experimental results related to the effects of ocean acidification on planktonic marine microbes are still rather inconsistent and occasionally contradictory. Moreover,... -
Effect of increased pCO2 on bacterial assemblage shifts in response to glucos...
Ocean acidification may stimulate primary production through increased availability of inorganic carbon in the photic zone, which may in turn change the biogenic flux of... -
Seawater carbonate chemistry, citrate synthase (CS), cytochrome c oxidase (CO...
In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne and Gattuso, 2011) was used to compute a complete and consistent... -
Response of Nodularia spumigena to pCO2 - Part 3: Turnover of phosphorus comp...
Diazotrophic cyanobacteria often form extensive summer blooms in the Baltic Sea driving their environment into phosphate limitation. One of the main species is the heterocystous... -
Ocean acidification slows nitrogen fixation and growth in the dominant diazot...
Dissolution of anthropogenic CO(2) increases the partial pressure of CO(2) (pCO(2)) and decreases the pH of seawater. The rate of Fe uptake by the dominant N(2)-fixing... -
Experiment: Elevated CO2 levels affect the activity of nitrate reductase and ...
The concentration of CO2 in global surface ocean waters is increasing due to rising atmospheric CO2 emissions, resulting in lower pH and a lower saturation state of carbonate... -
Seawater carbonate chemistry and egg production, hatching and metabolic rates...
This study includes the first information on the combined effect of low pH and raised temperature on egg production rate (EP), hatching success (HS), excretion and respiration... -
Tolerance of juvenile Mytilus galloprovincialis to experimental seawater acid...
Coastal ocean acidification is expected to interfere with the physiology of marine bivalves. In this work, the effects of acidification on the physiology of juvenile mussels... -
Seawater carbonate chemistry and concentration boundary layers around complex...
Metabolic processes have the potential to modulate the effects of ocean acidification (OA) in nearshore macroalgal beds. We investigated whether natural mixed assemblages of the... -
