Self-isolation

open access: yesJournal 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.

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.

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-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 ...

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.

The limits of mean-field heterozygosity estimates under spatial extension in simulated plant populations [PDF]

open access: yes, 2012
Computational models of evolutionary processes are increasingly required to incorporate multiple and diverse sources of data. A popular feature to include in population genetics models is spatial extension, which reflects more accurately natural ...

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 ...

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.

Potential inbreeding in a small population of a mass flowering species, Xanthorrhoea johnsonii (Xanthorrhoaceae): is your mother my father? [PDF]

open access: yes, 2012
Xanthorrhoea johnsonii is a long lived slow growing perennial understorey species, that produces a large quantity of passively dispersed seed every 3-5 years. Reproductive maturity is not reached until 20-30 years of age.
