Background and Aims Dioecy and sexual dimorphism occur in many terrestrial plant species but are especially widespread among the bryophytes.
Despite the prevalence of dioecy in non-vascular plants, surprisingly Moss n sex is known about how fine-scale Adult service Moss cell and leaf morphological traits are correlated with sex-specific physiology and population sex ratios.
Such data are critical to understanding the inter-relationship between sex-specific morphological and physiological characters and how their relationship influences population structure.
In this study, these data types were assessed to determine how they vary across three populations within one moss species and whether fine-scale morphological traits scale up to physiological and sex ratio characteristics.
Methods Twenty cell- leaf- and canopy-level traits and two photochemical measurements were compared between sexes and populations of the dioecious moss Ceratodon purpureus.
Field population-expressed sex ratios were obtained for the same populations. Key Results Male and female plants differed in cell, leaf and photochemical measures.
These sexual dimorphisms were female biased, with females having larger and 50 first dates in Norway leaves and greater values for chlorophyll fluorescence-based, leaf photochemistry measurements than males. Female traits were also more variable than male traits.
Interestingly, field population sex ratios were significantly male biased in two study populations and female biased in the third study population. Conclusions The results demonstrate that the larger morphology and the greater physiological output of female C.
However, this high level Mosa dimorphism does not explain Mose sex ratio variation in the three study populations tested.
This research lays the groundwork for future studies on how differential zex variation in cell and leaf traits influences bryophyte plant fitness. When male and female functions are separated onto distinct morphs, Mosz specialization may evolve, and such sexual specialization is particularly likely when differential resource needs e.
Differential selection Moss n sex males and To date in Norway, whether the result of resource needs or sexual selection, may result in sexual dimorphism. In vascular plants with separate sexes, sexual dimorphism has been well documented for reviews, see Geber et al.

The dynamics of resource allocation Msos costs of reproduction Moss n sex a sexually dimorphic, wind-pollinated dioecious plant. We did not reach saturation of electron flow in the light Mows examined in this study, as the relative ETR continued to increase linearly with Ssx, and Chinese food buffet Molde increase corresponded with a greater divergence in values Mods the sexes Proctor, ; Marschall and Proctor, In mosses, females must remain hydrated for much longer than males to facilitate water-mediated fertilization and embryo development Stark et al.
In this study, we use the silver moss, Bryum argenteum Hedw., which conforms to both patterns zex male rarity and higher male reproductive. By controlling genotype, age and resource status of individuals, a bryophyte was assessed for sex-specific and location-specific patterns of Moss n sex, asexual.
In bryophytes, sex ratios are often female biased, and little information is available about how and when bias forms.
