Reduction of a metapopulation genetic model to an effective one island model [PDF]

, 2018
We explore a model of metapopulation genetics which is based on a more ecologically motivated approach than is frequently used in population genetics. The size of the population is regulated by competition between individuals, rather than by artificially

Neutral genomic signatures of host-parasite coevolution

BMC Evolutionary Biology, 2019
Background Coevolution is a selective process of reciprocal adaptation in hosts and parasites or in mutualistic symbionts. Classic population genetics theory predicts the signatures of selection at the interacting loci of both species, but not the ...

Population genetics of forest trees.

Silva Fennica, 1982
The publication comprises proceedings of a conference held in Helsinki in 1981. Forest tree populations are investigated for population genetic structure, mating systems, mechanisms of genetic adaptation and ecological adaptation.

Genetic draft, selective interference, and population genetics of rapid adaptation [PDF]

, 2013
To learn about the past from a sample of genomic sequences, one needs to understand how evolutionary processes shape genetic diversity. Most population genetic inference is based on frameworks assuming adaptive evolution is rare.

Population genetics in compressible flows

, 2011
We study competition between two biological species advected by a compressible velocity field. Individuals are treated as discrete Lagrangian particles that reproduce or die in a density-dependent fashion.

Imputation Estimators Partially Correct for Model Misspecification [PDF]

, 2010
Inference problems with incomplete observations often aim at estimating population properties of unobserved quantities. One simple way to accomplish this estimation is to impute the unobserved quantities of interest at the individual level and then take ...

Population genetics models of local ancestry

, 2012
Migrations have played an important role in shaping the genetic diversity of human populations. Understanding genomic data thus requires careful modeling of historical gene flow.

Exploring the effects of ecological parameters on the spatial structure of genetic tree sequences

Peer Community Journal
Geographic space is a fundamental dimension of evolutionary change, determining how individuals disperse and interact with each other. Consequently, space has an important influence on the structure of genealogies and the distribution of genetic variants

Epistatic regulation of growth in Atlantic salmon revealed: a QTL study performed on the domesticated-wild interface

BMC Genetics, 2020
Background Quantitative traits are typically considered to be under additive genetic control. Although there are indications that non-additive factors have the potential to contribute to trait variation, experimental demonstration remains scarce.

Little evidence of inbreeding depression for birth mass, survival and growth in Antarctic fur seal pups

Scientific Reports
Inbreeding depression, the loss of offspring fitness due to consanguineous mating, is generally detrimental for individual performance and population viability.
