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 کاملProduction of Ice Nucleation Deficient (Ice-) Mutants of the Epiphytic Strains of Erwinia herbicola
To mutate the Ice Nucleation Active (INA) gene in Erwinia herbicola strains, Tn-5 transposon carried by Psup2021 plasmid was used. This plasmid was transferred to the bacterial cells by electroporation. Electrotransformation was carried out for 2.5 ms at 1800 v and 1 mm distance between the electrodes. Polymerase chain reaction was used for determination of presence or loss of INA gene, using a...
