Desiccation-tolerance in bryophytes: a review
Abstract Desiccation-tolerance (DT), the ability to lose virtually all free intracellular water and then recover normal function upon rehydration, is one of the most remarkable features of
Sex expression, skewed sex ratios, and microhabitat distribution in the dioecious desert moss Syntrichia caninervis (Pottiaceae).
It is hypothesized that mixed-sex populations are rare because of factors relating to male rarity and that the differential cost of sex expression reduces the clonal growth capacity of male individuals.
Sex Expression, Plant Size, and Spatial Segregation of the Sexes Across a Stress Gradient in the Desert Moss Syntrichia caninervis
It is hypothesized that males are less stress tolerant than females and that this condition may be an outgrowth of the sexes allocating differential resources to sexual reproduction.
Age and sex-specific rates of leaf regeneration in the Mojave Desert moss Syntrichia caninervis.
The extremely skewed female-biased sex ratio in the desert moss Syntrichia caninervis was investigated by assessing the regeneration capacity of detached leaves, and the more rapid proliferation of shoots by female leaf regenerants may help to explain the rarity of males in this species.
The cost of realized sexual reproduction: assessing patterns of reproductive allocation and sporophyte abortion in a desert moss.
The desert moss Syntrichia caninervis exhibits one of the most skewed sex ratios in the plant kingdom, with female individuals far outnumbering male individuals, and the cost of sex hypothesis, which predicts that the sex which is most expensive should be the rarer sex, is supported.
Do the Sexes of the Desert Moss Syntrichia caninervis Differ in Desiccation Tolerance? A Leaf Regeneration Assay
It is concluded that the leaf regeneration assay works well as a response variable for desiccation tolerance (DT) studies and that sex‐based DT, at least with respect to responses to rapid drying cycles in the lab, while not indicated in Syntrichia, may yet operate under field conditions.
Evidence of drought-induced stress on biotic crust moss in the Mojave Desert
It is concluded that this chlorosis phenomenon is indicative of physiological stress presently occurring in the Mojave Desert, and is likely due to exposure to a higher than normal frequency of light rain events, which serve to partially hydrate moss patches that then rapidly desiccate.
Sex expression and growth rates in natural populations of the desert soil crustal moss Syntrichia caninervis
The slow growth rates, low rates of sex expression, absence of male plants, and absence of sexual reproduction in this crustal species may help explain why re-establishment of mosses on desert soils can take decades.
Sex ratios and the shy male hypothesis in the moss Bryum argenteum (Bryaceae)
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.
