“Every day I grew stronger and stronger being there”.: empowerment through land-and art-based Peer Leader retreats with Indigenous and Northern young people

open access: yesInternational Journal of Circumpolar Health, 2022
Indigenous adolescents in Canada are among those shouldering the impacts of colonialism and racism. Peer approaches and art-and-land-based programming have demonstrated promise to support empowerment and well-being, yet little is known about their ...

Genetic variation and reproductive patterns in wetland mosses suggest efficient initial colonization of disturbed sites

open access: yesEcology and Evolution, 2021
To understand colonization processes, it is critical to fully assess the role of dispersal in shaping biogeographical patterns at the gene, individual, population, and community levels.

Molecular Mechanism Underlying Derepressed Male Production in Hexaploid Persimmon

open access: yesFrontiers in Plant Science, 2020
Sex expression in plants is often flexible and contributes to the maintenance of genetic diversity within a species. In diploid persimmons (the genus Diospyros), the sexuality is controlled by the Y chromosome-encoded small-RNA gene, OGI, and its ...

Sex-biased gene expression and recent sex chromosome turnover [PDF]

open access: yesPhilosophical Transactions of the Royal Society B, 2021
Abstract Cichlids are well known for their propensity to radiate generating arrays of morphologically and ecologically diverse species in short evolutionary time. Following this rapid evolutionary pace, cichlids show high rates of sex chromosome turnover. We here studied the evolution of sex-biased gene (SBG) expression in 14 recently

Modulation of Sex Expression in Four Forms of Watermelon by Gibberellin, Ethephone and Silver Nitrate

open access: yesHorticultural Plant Journal, 2017
There has been no systematic research on the effect of plant growth regulators and silver nitrate treatments on the control of sex expression in watermelon. In this study, we tested sex expression responses of four watermelon forms (monoecism, gynoecism,

Effect of different physio-chemical factors on sex expression and fruit yield in green-house cucumber

open access: yesAdvances in Horticultural Science, 2017
Male flower expression is considered an important aim in greenhouse cucumber breeding for creating paternal lines as a base for hybrid progeny. The study was carried out to evaluate the effects of different treatments on sex expression and fruit yield of

Balancing sex chromosome expression and satisfying the sexes [PDF]

open access: yesFly, 2012
Equalizing sex chromosome expression between the sexes when they have largely differing gene content appears to be necessary, and across species, is accomplished in a variety of ways. Even in birds, where the process is less than complete, a mechanism to reduce the difference in gene dose between the sexes exists. In early development, while the dosage

Vocal Emotional Expression in Parkinson’s Disease: Roles of Sex and Emotions

open access: yesSocieties, 2023
Introduction: Parkinson’s disease (PD) commonly causes speech impairments, including difficulties in expressing emotions through voice. Method: The objective of this study was to investigate gendered vocal expressions of fear, anger, sadness, and ...
