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 ...

Power and limits of selection genome scans on temporal data from a selfing population

open access: yesPeer Community Journal, 2021
Tracking genetic changes of populations through time allows a more direct study of the evolutionary processes acting on the population than a single contemporary sample.

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 ...

Mutation accumulation in a selfing population: consequences of different mutation rates between selfers and outcrossers. [PDF]

open access: yesPLoS ONE, 2012
Currently existing theories predict that because deleterious mutations accumulate at a higher rate, selfing populations suffer from more intense genetic degradation relative to outcrossing populations.

Self-medication and self-prescription [PDF]

open access: yesGaceta Médica de México, 2023
Self-medication and self-prescription are actions undertaken by patients; the former, as an element of self-care that involves over-the-counter drugs, and the latter, as a violation of the Statute of Health, since it includes drugs that can only be dispensed with a medical prescription. All the drawbacks that have been attributed to self-medication are

Selfing and Drought-Stress Strategies Under Water Deficit for Two Herbaceous Species in the South American Andes

open access: yesFrontiers in Plant Science, 2019
Angiosperms are highly diverse in their reproductive systems, including predominantly selfing, exclusive outcrossing, and mixed mating systems. Even though selfing can have negative consequences on natural populations, it has been proposed that plants ...

Assessment of the breeding system in the Algerian narrow coastal endemism Anacyclus linearilobus (Anthemideae, Asteraceae)

open access: yesAnales del Jardín Botánico de Madrid, 2022
The breeding system of Anacyclus linearilobus, an annual and endemic species restricted to dune ecosystems of the Algerian coast were assessed through the effect of self-fertilization and intra- and inter-population artificial crosses on the probability

Self-pollination by sliding pollen in Caulokaempferia coenobialis (Zingiberaceae) [PDF]

open access: yes, 2005
Caulokaempferia coenobialis (Zingiberaceae) forms dense populations on steep cliffs in shady, humid monsoon forests in south China. It produces few consecutively opening bright yellow flowers that are 3 cm long and oriented parallel to the ground.

Gene expression drives the evolution of dominance. [PDF]

open access: yes, 2018
Dominance is a fundamental concept in molecular genetics and has implications for understanding patterns of genetic variation, evolution, and complex traits.

Evolution of flowering time in a selfing annual plant: Roles of adaptation and genetic drift

open access: yesEcology and Evolution, 2022
Resurrection studies are a useful tool to measure how phenotypic traits have changed in populations through time. If these trait modifications correlate with the environmental changes that occurred during the time period, it suggests that the phenotypic ...
