A genome‐wide investigation of the worldwide invader Sargassum muticum shows high success albeit (almost) no genetic diversity [PDF]

open access: yesEvolutionary Applications, 2020
Twenty years of genetic studies of marine invaders have shown that successful invaders are often characterized by native and introduced populations displaying similar levels of genetic diversity.

Hybridization generates a hopeful monster: a hermaphroditic selfing cichlid [PDF]

open access: yesRoyal Society Open Science, 2016
Compared with other phylogenetic groups, self-fertilization (selfing) is exceedingly rare in vertebrates and is known to occur only in one small clade of fishes.

Long-term balancing selection drives evolution of immunity genes in Capsella [PDF]

open access: yeseLife, 2019
Genetic drift is expected to remove polymorphism from populations over long periods of time, with the rate of polymorphism loss being accelerated when species experience strong reductions in population size.

Propensity for selfing varies within a population of hermaphroditic snails: coexistence of selfers, outcrossers and mixed-mating individuals

open access: yesRoyal Society Open Science, 2023
To understand mating-system evolution in self-compatible hermaphrodites, variation in selfing rates is highly relevant. Empirical studies are rarely designed to capture variation between individuals, instead often comparing species and populations.

Phenotypic Selection in Halenia elliptica D. Don (Gentianaceae), an Alpine Biennial with Mixed Mating System

open access: yesPlants, 2022
The transition from outcrossing to selfing is a common evolutionary trend in flowering plants, and floral traits change significantly with the evolution of selfing.

Self-Fertilization, Inbreeding, and Yield in Alfalfa Seed Production

open access: yesFrontiers in Plant Science, 2021
Selfing (self-pollination) is the ultimate form of inbreeding, or mating among close relatives. Selfing can create yield loss when inbreeding depression, defined as a lower survival and reproduction of inbred relative to outbred progeny, is present.

Evolution of the Selfing Syndrome in Arabis alpina (Brassicaceae). [PDF]

open access: yesPLoS ONE, 2015
The transition from cross-fertilisation (outcrossing) to self-fertilisation (selfing) frequently coincides with changes towards a floral morphology that optimises self-pollination, the selfing syndrome.

Joint inference of evolutionary transitions to self-fertilization and demographic history using whole-genome sequences

open access: yeseLife, 2023
The evolution from outcrossing to selfing occurred recently across the eukaryote tree of life in plants, animals, fungi, and algae. Despite short-term advantages, selfing is hypothetically an evolutionary dead-end reproductive strategy.

Mating system of Datura inoxia: association between selfing rates and herkogamy within populations [PDF]

open access: yesPeerJ, 2021
Plant mating system determines, to a great extent, the demographic and genetic properties of populations, hence their potential for adaptive evolution. Variation in plant mating system has been documented between phylogenetically related species as well ...

Mating system and speciation I: Accumulation of genetic incompatibilities in allopatry.

open access: yesPLoS Genetics, 2022
Self-fertilisation is widespread among hermaphroditic species across the tree of life. Selfing has many consequences on the genetic diversity and the evolutionary dynamics of populations, which may in turn affect macroevolutionary processes such as ...
