We suggest a possible correlation between the ionization events caused by the background neutron radiation and the experimental data on mutations with damage in the DNA repair mechanism, coming from the Long Term Evolution Experiment in E. Coli populations.
B cell receptor sequences diversify through mutations introduced by purpose-built cellular machinery. A recent paper has concluded that a templated mutagenesis process is a major contributor to somatic hypermutation, and therefore immunoglobulin dive
We provide quantitative estimates on the size and the structure of the epistatic space defined in the main article, Dynamical Correlations in the escape strategy of Influenza A virus, EPL 101 68003.
A tragedy of the commons (TOC) occurs when individuals acting in their own self-interest deplete commonly-held resources, leading to a worse outcome than had they cooperated. Over time, the depletion of resources can change incentives for subsequent
The stabilizing effects of local enrichment are revisited. Diffusively coupled host-parasitoid and predator-prey metapopulations are shown to admit a stable fixed point, limit cycle or stable torus with a rich bifurcation structure. A linear toy mode
Mediterranean ecosystems such as those found in California, Central Chile, Southern Europe, and Southwest Australia host numerous, diverse, fire-adapted micro-ecosystems. These micro-ecosystems are as diverse as mountainous conifer to desert-like cha
