Hitchhiking to speciation. [PDF]

PLoS Biology, 2013
The modern evolutionary synthesis codified the idea that species exist as distinct entities because intrinsic reproductive barriers prevent them from merging together. Understanding the origin of species therefore requires understanding the evolution and

The clarifying role of time series data in the population genetics of HIV

bioRxiv, 2018
HIV can evolve remarkably quickly in response to anti-retroviral therapies and the immune system. This evolution stymies treatment effectiveness and prevents the development of an HIV vaccine.

Fixation dynamics of beneficial alleles in prokaryotic polyploid chromosomes and plasmids

bioRxiv, 2022
Theoretical population genetics has been mostly developed for sexually reproducing diploid and for monoploid (haploid) organisms, focusing on eukaryotes.

Technologically modified genes in natural populations [PDF]

, 1993
Current theories of evolutionary and ecological genetics cannot be used for general statements on risk assessment of gene technology. In a simplifying model, the genes which are transferred from artificial populations are treated like mutations in the ...

Genotype by random environmental interactions gives an advantage to non-favored minor alleles

Scientific Reports, 2017
Fixation probability, the probability that the frequency of a newly arising mutation in a population will eventually reach unity, is a fundamental quantity in evolutionary genetics.

Simulating population genetics of pathogen vectors in changing landscapes: guidelines and application with Triatoma brasiliensis. [PDF]

PLoS Neglected Tropical Diseases, 2014
BACKGROUND:Understanding the mechanisms that influence the population dynamics and spatial genetic structure of the vectors of pathogens infecting humans is a central issue in tropical epidemiology.

Fixation of genetic variation and optimization of gene expression: The speed of evolution in isolated lizard populations undergoing Reverse Island Syndrome

PLOS ONE, 2019
The ecological theory of island biogeography suggests that mainland populations should be more genetically divergent from those on large and distant islands rather than from those on small and close islets. Some island populations do not evolve in a linear way, but the process of divergence occurs more rapidly because they undergo a series of ...

Population and evolutionary genetics of the PAH locus to uncover overdominance and adaptive mechanisms in phenylketonuria: Results from a multiethnic study

EBioMedicine, 2020
Background Phenylketonuria (PKU) is the most common inborn error of amino acid metabolism in Europe. The reasons underlying the high prevalence of heterozygous carriers are not clearly understood.

Impact of barriers on Cyrno‐Sardinian endemisms: A comparative study of population genetics and phylogeography within taxa of Centranthus sect. Nervosae (Caprifoliaceae)

Plant biology
This study explores the impact of geographic barriers on the distribution and survival of Mediterranean endemic species, focusing on Centranthus sect. Nervosae, a tetraploid species complex found in Corsica and Sardinia.
