“…Hypnum cupressiforme and Polytrichum formosum) were not present in the diaspore bank. The absence of Polytrichum formosum is a surprising result, because it was fairly abundantly present in several previous studies Jonsson, 1993;Iglesias et al, 2015).…”

“…Comparative studies between forest-floor bryophytes and diaspore banks in forests are also sparse Jonsson, 1993;Rydgren & Hestmark, 1997;Hebrard, 2001;Rydgren et al, 2004;Szű cs, 2013;Iglesias et al, 2015). Our investigation aimed to explore the environmental drivers of the diversity and composition of the bryophyte diaspore bank of temperate mixed forests, and to compare it with the forest-floor bryophyte assemblage.…”

Species richness, composition and abundance of the bryophyte diaspore bank of Central European temperate mixed forests were compared with the forest-floor bryophyte assemblage. The impact of environmental variables and anthropogenic disturbances, including tree species composition, stand structure, microclimate, light conditions, soil and litter properties, management history, and landscape properties, potentially influencing bryophyte diaspore bank assemblages were explored. Thirty-four, 70-100 years old mixed stands with differing tree species composition were examined in the Ő rség National Park, Western Hungary. The diaspore bank was studied by soil collection and cultivation, and data were analysed by multivariate methods. Contrary to the forest-floor bryophyte assemblage, where substrate availability, tree species composition and stand structure were the most influential environmental variables, the composition and abundance of the diaspore bank was mainly affected by site conditions (microclimate, litter and soil properties). Species richness of the bryophyte diaspore bank was lower than that of the forest-floor bryophyte assemblage. Short-lived mosses (colonists, short-lived shuttles) were dominant in the diaspore bank, as opposed to the forest-floor bryophyte community, where perennial mosses dominated. In the studied forests, the importance of the bryophyte diaspore bank was relatively low in the regeneration and maintenance of the forest-floor bryophyte vegetation.

“…Species composition of bryophytes often differs between the diaspore bank and above-ground assemblages (Rydgren and Hestmark 1997). Typically, colonist species dominate in the diaspore bank, while perennial species dominate the aboveground community (During and ter Horst 1983;Eckstein 2006;Iglesias et al 2015;Jonsson 1993;Kövendi-Jakó et al 2016;Ross-Davis and Frego 2004). However, due to a scarcity of diaspore bank studies, the generality of the differences between diaspore bank vs. above-ground is not well understood.…”

Purpose Soil diaspore banks of bryophytes are poorly known in tundra grasslands, yet can be important for the maintenance of local bryophyte assemblages. We examined the effects of fertilization and grazing exclusion on above-ground bryophyte assemblages and soil diaspore banks in a tundra grassland. Methods We collected soil diaspore samples and recorded the cover of above-ground bryophytes from a full-factorial experiment with NPK fertilization and grazing exclusion treatments (a Nutrient Network site in NW Finland). Soil diaspore samples were germinated on trays in a greenhouse. We analyzed the compositions of diaspore bank assemblages and of above-ground assemblages and assessed their responses to the experimental treatments. Results The diaspore bank contained c. 50% of taxa found in above-ground assemblages; 26 bryophyte taxa germinated from the diaspore bank, while 40 taxa were found in the above-ground assemblages. These communities had distinct species compositions: the diaspore bank was dominated by Pohlia nutans, while above-ground assemblages were dominated by several species. NPK fertilization and grazing exclusion had negative effects on bryophyte richness and cover in above-ground assemblages, and weaker effects on these responses in the diaspore bank. Conclusion Soil diaspore banks comprise about half of the bryophyte taxa encountered in above-ground assemblages. Bryophyte diaspore banks are more buffered against nutrient enrichment and grazing exclusion than above-ground assemblages, suggesting that diaspore banks may enhance persistence and recovery of local bryophyte assemblages from environmental changes.

“…Cryptogams have no particular fire-adapted survival strategies and rely on airborne spores or propagules to disperse to new habitat (e.g., Flø andHågvar 2013, Nascimbene et al 2017). The bank of bryophyte diaspores in the soil, originating from fallout or in situ production, represents a source of latent propagules awaiting suitable conditions for germination and growth (Biggs and Wit-tkuhn 2006, Iglesias et al 2015, Glime 2017. Although bryophyte diaspores in the soil may survive fire , the extent of this strategy in eucalypt forest is unknown.…”
