Self-fertilization in mosses: a comparison of heterozygote deficiency between species with combined versus separate sexes
TLDR
These data provide the first analysis of heterozygote deficiency and selfing among haploid-dominant species with breeding system variation, and the results with respect to the consequences of inbreeding depression and the evolution of breeding systems are discussed. Expand
GENDER‐SPECIFIC SELECTION DURING EARLY LIFE HISTORY STAGES IN THE DIOECIOUS GRASS DISTICHLIS SPICATA
TLDR
This study is the first to document environment-dependent differential seed germination and seedling mortality between males and females in a dioecious plant species and suggests that, in habitats with female majorities, gender-specific bias in seedling survivorship, rather than seed Germination, is a causal factor in the underlying sex-ratio bias. Expand
Sex-specific volatile compounds influence microarthropod-mediated fertilization of moss
TLDR
The results indicate the presence of a scent-based ‘plant–pollinator-like’ relationship that has evolved between two of Earth’s most ancient terrestrial lineages, mosses and microarthropods. Expand
Sex ratios and the shy male hypothesis in the moss Bryum argenteum (Bryaceae)
TLDR
It is proposed that factors between spore germination and adult maturation, including clonal dynamics, are causing the female-biased population and within-clump sex ratio imbalance of B. argenteum. Expand
Sporophytic inbreeding depression in mosses occurs in a species with separate sexes but not in a species with combined sexes.
TLDR
Examination of sporophytic traits of moss species with contrasting breeding systems provides evidence that, despite haploid dominance, inbreeding depression can be expressed at the diploid stage in mosses and may have implications for the evolution and maintenance of combined versus separate sexes in Mosses. Expand
Sex-specific variation in the interaction between Distichlis spicata (Poaceae) and mycorrhizal fungi.
TLDR
The results suggest that D. spicata males and females interact with mycorrhizal fungi differently, and the implications for the role of this sex-specific symbiotic interaction in the maintenance of the within-population sex ratio bias of D. Spicata are discussed. Expand
Moving to mate: the evolution of separate and combined sexes in multicellular organisms
TLDR
It is found that changes in adult mate‐search efficiency are significantly correlated with changes in breeding system, and this result is robust to uncertainties in the phylogenies. Expand
'Haldane's Sieve' in a metapopulation: sifting through plant reproductive polymorphisms.
TLDR
It is suggested that a process similar to Haldane's Sieve will act on migrants into subpopulations of a metapopulation, and that the repeated action of Haldanes Sieve on alleles maintained by frequency-dependent selection is expected to bias their frequency distribution in favour of dominant alleles. Expand
Inter-sexual competition in a dioecious grass
TLDR
This work examined whether reciprocally transplanted male and female seedlings of Distichlis spicata, a dioecious grass species that exhibits extreme SSS, differed in their responses to microhabitats and competition treatments. Expand
Passive warming reduces stress and shifts reproductive effort in the Antarctic moss, Polytrichastrum alpinum
TLDR
Results from this study of mosses under passive warming imply that in ice-free moss-dominated regions, continued climate warming will probably have profound impacts on moss biology and colonization along the Western Antarctic Peninsula. Expand
