population growth
A new class of competition models in which the population growth coefficients are represented by periodic delta-functions is designed.
      
Analysis of the available field and published data indicates a two-stage pattern of the population growth phase and a synchronous transition of wolf populations to this phase.
      
Selenium in concentrations of 0.01 and 0.5 mg/liter stimulated cell population growth, while the number of ultrastructural alterations was the same as in the control cells.
      
At a selenium concentrations of 1 mg/liter, cell population growth slightly decreased by the end of the experiment, and there was some increase in the number of cells with damaged organoids and in the number of completely destroyed cells.
      
salina, suppressing cell population growth and promoting extensive destructive changes.
      
Though there were no ultrastructural alterations in microalgal cells from medium with 0.5 mg Se/liter, we assume that they had molecular defects that could inhibit the cell population growth.
      
Analysis of Survival of the Red Fox (Vulpes vulpes L.) at the Phases of Population Growth and Decline
      
It was found that the survival rate in all age classes, including newborns, drastically increased at the phase of population growth.
      
The population growth experiments were terminated after 19 days.
      
The rate of population growth ranged from 0.002 to 0.578 for B.
      
The hybridization activity of the virus strains isolated at the phase of gypsy moth population growth was significantly higher (p >amp;lt; 0.001) than the activity of the strains isolated at the phase of population decrease.
      
Population growth can be expected when population develops on primary hosts with sufficient content of nutrients in the leaves and a certain carbohydrate to protein ratio, as well as a certain ratio of water-and alkali-soluble protein fractions.
      
The rate of reproduction (R0) decreased and, therefore, further population growth slowed down only after the initial abundance of the generation had reached a relatively high level.
      
The SNG system provides a very powerful tool for describing the kinetics of bacterial population growth.
      
During the last two decades, the area witnessed substantial increase in athropogenic pressure, mainly due to the exploitation of hydropower potential, changing landuse pattern and population growth.
      
The results obtained implies that the relationship between the technological change and population growth rate determinated by the economic structure and the parental ethies.
      
The conflicts between population growth, insufficient grain supply and stagnant economic development sharpen increasingly.
      
The evaluation of the status, rate and risk of urbanization are based on an accepted average of urban increase as 2% of population growth per year.
      
The population growth rate and the elasticity of the survival and reproduction parameters have been determined analytically.
