Emergence of biodiversity in microbial populations
It is well known that food stress resulting from density-dependent factors affects the mutation rate and hence promotes diversity. It is also known that in bacterial cultures the quality and composition of the growing media conditions the emergence of different spatial patterns. We would like to address the following question: how will the different spatial regions with well defined geometrical...

متن کاملEvolutionary Forces Influencing Variation among Populations of Pinus sylvestris
The evolutionary forces influencing genetic differentiation among populations are identified. Natural selection, random genetic drift, and mutations promote differentiation while phenotypic plasticity and gene flow delay or prevent differentiation. Evolution is a dynamic force which leads to instability and absence of any perfection in the adaptive process. Natural selection acts mainly on phen...
متن کاملEco-evolutionary feedbacks can rescue cooperation in microbial populations
Bacterial populations whose growth depends on the cooperative production of public goods are usually threatened by the rise of cheaters that do not contribute but just consume the common resource. Minimizing cheater invasions appears then as a necessary mechanism to maintain these populations. However, that invasions result instead in the persistence of cooperation is a prospect that has yet re...
متن کاملEvolutionary consequences of intra-patient phage predation on microbial populations
The impact of phage predation on bacterial pathogens in the context of human disease is not currently appreciated. Here, we show that predatory interactions of a phage with an important environmentally transmitted pathogen, Vibrio cholerae, can modulate the evolutionary trajectory of this pathogen during the natural course of infection within individual patients. We analyzed geographically and ...
