Inorganic nutrient limitation of oceanic bacterioplankton
Although it is commonly accepted that dissolved organic carbon (DOC) of algal origin limits bacterial growth in pelagic systems, there arc relatively few empirical studies documenting this effect. Depending on site and season, both organic and inorganic nutrients can limit the growth of freshwater bacteria. By contrast, inorganic nutrients have only recently been implicated as potentially growt...
متن کاملUncoupling of bacterioplankton and phytoplankton production in fresh waters is affected by inorganic nutrient limitation.
Pelagic bacterial production is often positively correlated, or coupled, with primary production through utilization of autotrophically produced dissolved organic carbon. Recent studies indicate that inorganic N or P can directly limit both bacterial and phytoplanktonic growth. Our mesocosm experiments, with whole communities from mesotrophic Calder Lake, test whether this apparent bacterial-al...
متن کاملProcesses and patterns of oceanic nutrient limitation
1 The biomass of all living organisms consists of around 30 of the 92 naturally occurring elements (Fig. 1a and Supplementary Table S1)1,2. All organisms must obtain chemical forms of these essential elements, termed nutrients, from their external environment. The key role that nutrients play in controlling upper-ocean productivity has long been recognized3–5. Research over recent decades, howe...
متن کاملNutrient limitation of bacterioplankton growth in Lake Dillon, Colorado
Bacterioplankton biomass, production, and growth rate were measured over a 2-yr period in Lake Dillon, a mesotrophic Colorado reservoir. In addition, a multivariate statistical analysis and nutrient addition experiments were used to analyze the regulation of bacterioplankton growth in situ. Biomass ranged between 170 (winter) and 2,200 mg C m-* (summer); production ranged from 10 (winter) to 62...
متن کاملNutrient co-limitation of primary producer communities.
Synergistic interactions between multiple limiting resources are common, highlighting the importance of co-limitation as a constraint on primary production. Our concept of resource limitation has shifted over the past two decades from an earlier paradigm of single-resource limitation towards concepts of co-limitation by multiple resources, which are predicted by various theories. Herein, we sum...
