Epiphytic bryophyte and lichen transplant niches along an elevational gradient in Pacific Northwest coniferous forests

Abstract

Premise of the studyThere is a lack of knowledge about the ability of individual species to grow successfully outside of their realized niche. The present study aims to investigate two epiphytic bryophyte and two epiphytic lichen species in their fundamental and realized niches in the Pacific Northwest coniferous forest at low, mid and high elevations.MethodsTwo lowland epiphytic bryophyte species (Frullania nisquallensis, Neckera douglasii) and one lowland epiphytic lichen species (Usnea longissima) were transplanted to mid and high elevation sites. One high elevation epiphytic lichen species (Hypogymnia rugosa) was transplanted to mid and low elevation sites.Key resultsThe fundamental and realized niches of F. nisquallensis and U. longissima are close and that they can both successfully survive outside of their realized niches. Concerning N. douglasii, dispersal limitations could shape its distribution along elevation and local microclimate conditions could be important for its vitality.ConclusionsCertain bryophyte and lichen species can survive outside of their realized niches, information that can contribute to building knowledge about species niches along elevational gradients. Future studies should focus on cryptogam species interactions in a changing climate.This article is protected by copyright. All rights reserved.

Ecological niche and interspecific relationship of dominant bryophyte communities in stone walls of cities at different elevations, Guizhou, China

“…Previous studies have revealed the significant impact of ecological niches on altitude gradients on the abundance and richness of tree epiphytes [17] . Furthermore, there are distinct differences in the ecological niche of bryophytes across various altitude gradients, enabling them to survive in diverse environments [20] . Gaining insights into the ecological requirements and relationships of dominant bryophyte species along altitudinal gradients during resource utilization is crucial for the effective management and restoration of urban ecosystems.…”
