Is the growth of temperate forest trees enhanced along an ambient nitrogen deposition gradient?
The extent to which atmospheric N deposition is enhancing primary production and CO2 sequestration along the ambient N deposition gradients found within many regional temperate forest ecosystems remains unknown. We used tree diameter measurements from 1984 and 2004, allometric equations, and estimates of wet N deposition from 32 permanent plots located along an ambient N deposition gradient in ...
متن کاملImpact of Atmospheric Nitrogen Deposition on Carbon Storage Pathways along a Nitrogen Deposition Gradient in Coastal Sage Scrub Soils
Recent studies suggest that nitrogen can have significant effects on microbial activity and carbon storage by causing shifts in fungal:bacterial activity such that bacterial degradation pathways become dominant under high nitrogen conditions. If true, changes in fungal:bacterial (F:B) ratios could have a major impact on carbon storage in urban pollution affected soils that receive high amounts ...
متن کاملDramatic changes in ectomycorrhizal community composition, root tip abundance and mycelial production along a stand-scale nitrogen deposition gradient.
• Nitrogen (N) availability is known to influence ectomycorrhizal fungal components, such as fungal community composition, biomass of root tips and production of mycelia, but effects have never been demonstrated within the same forest. • We measured concurrently the abundance of ectomycorrhizal root tips and the production of external mycelia, and explored the changes in the ectomycorrhizal com...
متن کاملVARIATION IN LEAF MORPHOLOGY OF PARROTIA PERSICA ALONG AN ELEVATIONAL GRADIENT IN EASTERN MAZANDARAN PROVINCE (N. IRAN)
In order to investigate the variation within and among populations of Parrotia persica C.A. Meyer based on leaf morphological traits, three populations were selected from Behshar area, in the east of Mazandaran Province. The populations selected along a transect in different altitudes of 182, 340, 540 meter above the sea level, respectively. In each population, 10 trees were selected and some l...
متن کاملNonlinear root-derived carbon sequestration across a gradient of nitrogen and phosphorous deposition in experimental mesocosms
Enhanced sequestration of plant-carbon (C) inputs to soil may mitigate rising atmospheric carbon dioxide (CO2) concentrations and related climate change but how this sequestration will respond to anthropogenic nitrogen (N) and phosphorous (P) deposition is uncertain. We couple isotope, soil C fractionation and mesocosm techniques to assess the sequestration of plant-C inputs, and their partitio...
