Preventing self-fertilization: Insights from Ziziphus species [PDF]

open access: yesFrontiers in Plant Science, 2023
The fitness of self-progeny individuals is inferior to that of their outcrossed counterparts, resulting in a reduction in a plant population’s ability to survive and reproduce.

Evolutionary consequences of self-fertilization in plants. [PDF]

open access: yesProc Biol Sci, 2013
The transition from outcrossing to self-fertilization is one of the most common evolutionary changes in plants, yet only about 10–15% of flowering plants are predominantly selfing. To explain this phenomenon, Stebbins proposed that selfing may be an ‘evolutionary dead end’.

Inference of past demography, dormancy and self-fertilization rates from whole genome sequence data. [PDF]

open access: yesPLoS Genet, 2020
Several methods based on the Sequential Markovian Coalescent (SMC) have been developed to use full genome sequence data to uncover population demographic history, which is of interest in its own right and a key requirement to generate a null model for ...

Purging due to self-fertilization does not prevent accumulation of expansion load

open access: yesbioRxiv, 2022
Species range expansions are a common demographic history presenting populations with multiple evolutionary challenges. It is not yet fully understood if self-fertilization, which is often observed at species range edges, may create an evolutionary ...

Does the evolution of self-fertilization rescue populations or increase the risk of extinction? [PDF]

open access: yesAnn Bot, 2019
Background and Aims As a major evolutionary transition in seed plants, the evolution of plant mating systems has been much debated in evolutionary ecology. Over the last 10 years, well-established patterns of evolution have emerged.

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.

Inbreeding depression under mixed outcrossing, self-fertilization and sib-mating. [PDF]

open access: yesBMC Evol Biol, 2016
Biparental inbreeding, mating between two relatives, occurs at a low frequency in many natural plant populations, which also often have substantial rates of self-fertilization.

Assortative mating and self-fertilization differ in their contributions to reinforcement, cascade speciation, and diversification. [PDF]

open access: yesCurr Zool, 2016
Cascade speciation and reinforcement can evolve rapidly when traits are pleiotropic and act as both signal/cue in nonrandom mating. Here, we examine the contribution of two key traits—assortative mating and self-fertilization—to reinforcement and (by ...

The sex lives of ctenophores: the influence of light, body size, and self-fertilization on the reproductive output of the sea walnut, Mnemiopsis leidyi [PDF]

open access: yesPeerJ, 2016
Ctenophores (comb jellies) are emerging as important animals for investigating fundamental questions across numerous branches of biology (e.g., evodevo, neuroscience and biogeography).

Reproductive assurance drives transitions to self-fertilization in experimental Caenorhabditis elegans [PDF]

open access: yesBMC Biology, 2014
Evolutionary transitions from outcrossing between individuals to selfing are partly responsible for the great diversity of animal and plant reproduction systems.
