The Plant Genome, 2013 Two hundred sixteen barley ( L.) cultivars were selected to represent the diversity and history of European spring two-row barley breeding and to search for alleles controlling agronomic traits by association genetics.

Growth, competition and cooperation in spatial population genetics [PDF]
, 2012 We study an individual based model describing competition in space between two different alleles. Although the model is similar in spirit to classic models of spatial population genetics such as the stepping stone model, here however space is continuous ...

Bulletin of Mathematical Biology, 2016 Genetic diversity grows with the population size in most neutral evolution models. Empirical evidence of large populations with limited diversity has been proposed to be due either to genetic bottlenecks or to selection. An alternative explanation is that the limited diversity is a result of rare reproduction events.

Robust forward simulations of recurrent hitchhiking [PDF]
, 2014 Evolutionary forces shape patterns of genetic diversity within populations and contribute to phenotypic variation. In particular, recurrent positive selection has attracted significant interest in both theoretical and empirical studies.

The dynamics of alternative pathways to compensatory substitution [PDF]
, 2013 The role of epistatic interactions among loci is a central question in evolutionary biology and is increasingly relevant in the genomic age. While the population genetics of compensatory substitution have received considerable attention, most studies ...

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

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.

The look-ahead effect of phenotypic mutations [PDF]
, 2007 The evolution of complex molecular traits such as disulphide bridges often requires multiple mutations. The intermediate steps in such evolutionary trajectories are likely to be selectively neutral or deleterious.

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 ...
