Significance of bacteriophages for controlling bacterioplankton growth in a mesotrophic lake.
Bacterium-specific viruses have attracted much interest in aquatic microbial ecology because they have been shown to be about 10 times more abundant than planktonic bacteria. So far most of the studies of interactions of planktonic bacteria and viruses have been done in marine environments, and very little is known about these interactions in lakes. Therefore, we studied phage proliferation in ...
متن کاملBloom of filamentous bacteria in a mesotrophic lake: identity and potential controlling mechanism.
Ephemeral blooms of filamentous bacteria are a common phenomenon in the water column of oligo- to mesotrophic lakes. It is assumed that the appearance of such morphotypes is favored by selective predation of bacterivorous protists and that filter-feeding zooplankton plays a major role in suppressing these bacteria. The phylogenetic affiliation of the important bloom-forming filamentous bacteria...
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 کاملthe significance of conjunction as a cohesive device in teaching writing
the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
15 صفحه اولBacterioplankton in Lake Michigan : Dynamics , controls , and significance to carbon flux
Lake Michigan bacterial production, based on [3H-methyl]thymidine (TdR) incorporation and empirically determined conversion factors (5-25 x lo9 cells nmol-I), decreased with distance from shore (2 x over 30 km), was higher at night (1.4 x -2.2 x), and decreased with depth (w 10 x over 100 m). TdR-based growth rates were consistent with independent antibioticand dilution-based estimates. Populat...
