Some aspects in population growth rate

Some Biochemical Aspects of Growth *

The many-sided problem of growth is of perennial interest for the reason that it is a phenomenon common to lower living forms and to self-conscious individuals alike. Furthermore, it is recognized that behavior, the interplay of personalities, and questions of mental adjustment are influenced to no small degree by the changes incident to growth. It is obvious that the development of the fertili...

Metabolic rate constants: Some computational aspects

In this work we pose the question how reliable the Michaelis constant is as an enzyme kinetic parameter in situations when the MichaelisMenten equation is not a good approximation of the true substrate dynamics as it may be in the case of metabolic processes in living cells. We compare the Michaelis-Menten substrate-product kinetics with the complete substrateenzyme-product kinetics induced by ...

Population Dynamics of Metastable Growth-Rate Phenotypes

Neo-Darwinian evolution has presented a paradigm for population dynamics built on random mutations and selection with a clear separation of time-scales between single-cell mutation rates and the rate of reproduction. Laboratory experiments on evolving populations until now have concentrated on the fixation of beneficial mutations. Following the Darwinian paradigm, these experiments probed popul...

Growth rate, population entropy, and perturbation theory.

This paper is concerned with the connection between two classes of population variables: measures of population growth rate--the Malthusian parameter, the net reproduction rate, the gross reproduction rate, and the mean life expectancy; and measures of demographic heterogeneity--population entropy. It is shown that the entropy functions predict the response of the growth rate parameters to pert...
