Comparative Modeling of Coevolution in Communities of Unicellular Organisms: Adaptability and Biodiversity

Abstract

We propose an original program "Evolutionary constructor" that is capable of computationally efficient modeling of both population-genetic and ecological problems, combining these directions in one model of required detail level. We also present results of comparative modeling of stability, adaptability and biodiversity dynamics in populations of unicellular haploid organisms which form symbiotic ecosystems. The advantages and disadvantages of two evolutionary strategies of biota formation -a few generalists' taxa-based biota formation and biodiversity-based biota formation -are discussed.

Evolution, Biodiversity and Ecology in Microbial Communities: Mathematical Modeling and Simulation with the “Haploid Evolutionary Constructor” Software Tool

“…The beneficial mutations in such prokaryotic communities often extend the lifetime of the community significantly. The compensatory systems are more stable in continuously varying conditions from the viewpoint of preserving and growing biomass, while the non-compensatory systems are more stable when it comes to conserving biodiversity [54]. In this way, both strategies have their evolutionary advantages and disadvantages.…”

“…In this case there are several allelic variants for some (or for all) genes. The detail description of the modeling of genetic polymorphism via so called genetic spectra arithmetics was published in our previous studies [19]. Population-environment interactions are realized via metabolites transport in-/outside cells ( Fig.…”

“…The set of distribution for all genes variants (alleles) in a population is called "generalized population genome". Its further evolution is described with the use of so called genetic spectra arithmetics [19]. The user can also set up the general metabolism parameters of a population (mean utilization/ synthesis rates), death and flow parameters etc.…”

“…It may lead to the origin of a novel population [19]; ⎯ loss of gene(s) in some cell(s) of a population (also may lead to the origin of a novel population);…”

“…Simple synthesis strategy, previously described in our studies [19], is exampled in the file "SynthesisStrategySimple.cpp".…”
