Demongeot Jacques and Demetrius Lloyd. ? Natural selection and demographic drift : an empirical study of France (1860-1965). One of the central issues in demography concerns evaluating the effects of endogenous (socio-cultural and genetic) and exogenous (wars, epidemics,...) factors on temporal...

Demetrius Lloyd. Demography, Growth Rate and Entropy. The formal theory of thermodynamics is closely similar to the theory of stable populations. A close examination of this analogy shows that the concept of 'entropy' used in statistical mechanics to describe the number of possible states of a...

This article introduces the concept of network entropy as a characteristic measure of network topology. We provide computational and analytical support for the hypothesis that network entropy is a quantitative measure of robustness. We formulate an evolutionary model based on entropy as a...

This article is concerned with the characterization of invasion exponents in biological networks defined by a population of replicating elements: molecules, cells, higher organisms. We show that the outcome of competition between an invader and a resident population is a stochastic process,...

This article proposes a mechanism to explain allometric relations between basal metabolic rate and the body size of organisms. The model postulates that energy transduction in biological organisms is constrained by two classes of dynamical processes: The first process has its origin in quantum...
