“…Based on searches of herbarium records (http://bryophyteportal.org/portal/) and state checklists (Brinda et al. ), one species that emerged from the soil bank, Riccia cavernosa , was not previously known within at least 250 km of the study area. Propagule contaminants were not detected in sterile controls during the germination assays.…”

“…The ability of bryophyte soil banks to sustain regional species pools is demonstrated by the occurrence in soil of Riccia cavernosa , a liverwort for which the nearest previous report was ~250 km distant (at the western fringes of the Mojave Desert in California) and which had previously been reported from the state of Nevada only once (Brinda et al. ). The presence of cryptic species suggests that soil banks act as diversity reservoirs with hidden contributions to regional species pools.…”

Questions As changing wildfire regimes modify North American deserts, can fires of greater severity and frequency negatively impact the recovery of native bryophyte communities, which are not adapted to such disturbances? Does post‐fire recovery result from the survival of existing surface plants, dormant propagules in sub‐surface soil banks (dispersal in time) or aerial immigration into burned sites (dispersal in space)? Do wildfires negatively affect the survival of propagules in bryophyte soil banks? Location Continental arid shrublands, Mojave Desert, southwestern US. Methods We characterized bryophyte communities along a post‐fire chronosequence spanning three decades across sites where fires had different severities, ages and potential fuels. Three community profiles (surface, soil and aerial) were surveyed with a combination of on‐site surveys and emergence germination techniques. We tested for differences in beta diversity, species composition and richness with PERMDISP, PERMANOVA and linear mixed models, respectively. Results Burn severity was associated with differences in beta diversity, species composition and richness, while burn age was associated only with different composition and richness. No effect of potential fuel availability was found. More variation in composition was explained by significant differences among profiles than by other fire attributes. Species richness (but not beta diversity) was higher in soil profiles than in aerial spore rain or existing surface communities. Soils from the oldest and least severe burns had a greater number of species than soils from recent and more severe burns. Conclusions Bryophyte soil banks are common elements of desert soils that facilitate post‐disturbance recovery of communities, but soil banks are themselves threatened by the intensifying frequency and severity of wildfires in North American deserts. Recovery of desert bryophyte communities seems to begin (but not necessarily conclude) within 30 yr after wildfires. In the near future, communities may become perturbed from historical patterns as contemporary fire regimes undergo extensive changes.

“…Several living collections were sought through MO (Missouri Botanical Garden, St. Louis, Missouri, USA); however, all of these proved to be older collections and would not revive in culture. Two localities for the species are known from the state of Nevada (Brinda et al, 2007), and one of these populations was used in the current study, vouchered as follows: Stark s.n ., 30 Nov 2004 (UNLV), resampled May 2011, USA, Nevada, Clark County, River Mountains, 6.4 km northeast of downtown Henderson, 36°04’N, 114°55’W, Township 22S, Range 63E, Section 2, 638 m a.s.l. (site vegetation described in Stark, 2005).…”

For the first time, a desert moss is shown to exhibit an ecological strategy of desiccation tolerance that is inducible, challenging the assumption that arid-land bryophytes rely exclusively on constitutive protection. Results indicate that previous considerations defining a slow-dry event in bryophytes need reevaluation, and that the ecological strategy of inducible desiccation tolerance is probably more common than currently understood among terrestrial bryophytes.

“…The most recent published checklist of Nevada bryophytes listed 310 taxa (Brinda et al 2007). Other species new to science occurring in Nevada have subsequently been published (Greven 2010;Medina et al 2011;Spence and Shevock 2012).…”

“…Field collecting and inventory efforts continue to document new taxa for the Nevada bryoflora (Shevock et al 2005;Spence et al 2006). Many of the species reported herein have been reviewed, examined, or determined by persons involved in the bryophyte volumes of the Flora of North America Project (FNA 2007(FNA , 2014 (Brinda et al 2007). This species is likely to remain a very rare species in Nevada although it is widespread in fens in the Californian portion of the Sierra Nevada.…”
