Uptake of salmon-derived nitrogen by mosses and liverworts in coastal British Columbia
Throughout forested watersheds bordering the North Pacific, anadromous salmon (Oncorhynchus spp. ) are transferred into coastal forests by numerous predators and scavengers with remnants providing an important nutrient subsidy to riparian zones. The contribution of these nutrients to mosses and liverworts, which are the dominant ground cover of coastal forests, has not been investigated. We exa...
متن کاملShort-term effects of timber harvest and forest edges on ground-layer mosses and liverworts
Limited information exists on the effects of forest management practices on bryophytes, despite their importance to forest ecosystems. We examined short-term responses of ground-layer bryophytes to logging disturbance and creation of edges in mature Pseudotsuga forests of western Washington (USA). The abundance and richness of species were measured in four 1-ha forest aggregates (patches of int...
متن کاملA Proposal to Collect Bryophytes (mosses, Liverworts, and Hornworts) from the Jasper Ridge Biological Preserve
Bryophytes are the first lands plants that include three distinct lineages: mosses, liverworts, and hornworts. They differ primarily from the flowering plants by lacking roots, flowers, seeds, and a defined system of tissues for transporting fluids throughout the plant. Bryophytes reproduce not by seeds, but rather, single-celled spores. Many bryophytes can also form new plants by vegetative me...
متن کاملDeciphering the Evolution and Development of the Cuticle by Studying Lipid Transfer Proteins in Mosses and Liverworts
When plants conquered land, they developed specialized organs, tissues, and cells in order to survive in this new and harsh terrestrial environment. New cell polymers such as the hydrophobic lipid-based polyesters cutin, suberin, and sporopollenin were also developed for protection against water loss, radiation, and other potentially harmful abiotic factors. Cutin and waxes are the main compone...
متن کاملWorld checklist of hornworts and liverworts.
A working checklist of accepted taxa worldwide is vital in achieving the goal of developing an online flora of all known plants by 2020 as part of the Global Strategy for Plant Conservation. We here present the first-ever worldwide checklist for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) that includes 7486 species in 398 genera representing 92 families from the two phyla. The...
