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

Royal 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.

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

Evolutionary 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.

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

eLife, 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

Royal 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.

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

Frontiers 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.

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

Plants, 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.

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

PLoS 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.

Discovery of mating in the major African livestock pathogen Trypanosoma congolense [PDF]

, 2009
The protozoan parasite, Trypanosoma congolense, is one of the most economically important pathogens of livestock in Africa and, through its impact on cattle health and productivity, has a significant effect on human health and well being.

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

eLife, 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.

Self-isolation

Journal of Mathematical Economics, 2021
We analyze the spread of an infectious disease in a population when individuals strategically choose how much time to interact with others. Individuals are either of the severe type or of the asymptomatic type. Only severe types have symptoms when they are infected, and the asymptomatic types can be contagious without knowing it.
