Sentence examples for concentration abundance from inspiring English sources

We hypothesize that yeast communities should be determined by two different sets of parameters: (i) alterations in the floral habitat itself, such as nectar concentration, abundance, and sugar composition, and (ii) the yeast transfer conditions as a result of different flower visitor assemblages.

Equation 1 shows the change in abundance of a mutant in a chemostat (or turbidostat) as a function of time: (1) d X d t = μ X - D X Where X denotes hemizygote concentration (abundance in terms of number of cells, in arbitrary units) in the chemostat, t denotes time, μ denotes the growth rate of the mutant and D is the dilution rate, which is equal to the average growth rate of the population.

To this end we compiled data from our previous studies (2, 13− 17) and a study from the literature (12) to obtain a representative database comprising seven PCB-contaminated freshwater and marine sediments exhibiting a wide range of PCB concentrations, abundance of native BC, and other physicochemical characteristics.
