“…As predicted by previous studies (Ross‐Davis & Frego ; Caners, Macdonald & Belland ; Kövendi‐Jakó et al . ), there was little similarity between the extant and propagule rain communities. Colonist and acrocarp species occurred more in the propagule rain, while the extant community was dominated by perennial and pleurocarp species.…”

So close and yet so far away: long‐distance dispersal events govern bryophyte metacommunity reassembly

Summary Metapopulation dynamics have been used to explain bryophyte dispersal patterns and they predict that population abundances vary with the spatial distribution of habitat and with species traits. However, results from stand and landscape studies are contradictory as both distance‐dependent and distance‐independent patterns have been found. These studies have typically included only a few species, which limits interspecies comparison. It is the time to investigate bryophyte dispersal at the metacommunity scale. We studied bryophyte dispersal patterns in a system made up of burned matrices containing unburned residual forest patches. The importance of short‐ versus long‐distance dispersal was examined by comparing extant and propagule rain communities in residual forest patches of three fire sites using both species and life strategies. Extant and propagule rain communities were distinct. Several propagule rain species, of all life strategies, did not originate from the closest extant community, suggesting that regional dispersal events are important, following the inverse isolation hypothesis. Temporal, spatial and structural characteristics of the environment had a greater influence on dispersal than distance, which only influenced similarity patterns at the regional scale, highlighting the importance of propagule source attributes for the conservation of bryophyte metacommunities. Synthesis. Long‐distance dispersal may be the rule and not the exception in bryophyte metacommunities. Therefore, bryophyte metacommunity dynamics depend on several dispersal scales, and residual forest patches can contribute both to local and regional diaspore clouds. Species’ environmental tolerance during establishment and their ability to produce copious amounts of spores may be more important filters in bryophyte metacommunity dynamics than dispersal distance.

The influence of the community composition along with their cover explains the low abundance of species and asexual propagules found within the debris captured, but also how similar the captured propagules are to the communities detected within the boreal forest stands.…”

Asexual propagules produced by mosses and lichens may help to maintain their community composition in boreal forests. Understanding the factors affecting the deposition of asexual propagules and their link with the community composition may reveal how the community is maintained. The goal of this study was to understand how weather, the community of lichens and mosses, the dominant tree species in a stand, substrata, and tree aspect influenced and were linked to the deposition of asexual propagules (quantity, size, and type) in boreal forests. Species richness and cover were assessed for the substrata within the tree stands. Traps attached to trees and the ground (substrata) in balsam fir‐, white spruce‐, and poplar‐dominated stands were used to capture asexual propagules. Species and quantity of trapped asexual propagules were linked to the species richness and cover of the extant community. Propagules captured were dominated by lichen thallus fragments and were smaller and in higher quantities during colder times of the year, and in higher quantities and smaller sizes mostly on trees of conifer stands. Moss propagules were captured in low quantities compared to lichen propagules, on the forest floor, but mostly during warmer times of the year. The dispersal of mosses and lichen asexual propagules helps to maintain and is linked to their community in boreal forests. The linkage between asexual propagule deposition and the community (richness and abundance) was observed among lichen and moss communities on poplar trees, conifer trees, or the forest floor of boreal forest stands.

“…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.
