Concentration of Rare Epiphytic Lichens Along Large Streams in a Mountainous Watershed in Oregon, U.S.A
We studied epiphytic macrolichen communities and occurrences of rare species along the transition from upland to riparian forests on a range of stream sizes (intermittent, nonfish-bearing perennial, fish-bearing but less than 5th order, and streams larger than 5th order), based on 92, 0.38 ha plots in the McKenzie River watershed of the central Cascades of Oregon. The transition from uplands hi...
متن کاملAir pollution and climate gradients in western Oregon and Washington indicated by epiphytic macrolichens.
Human activity is changing air quality and climate in the US Pacific Northwest. In a first application of non-metric multidimensional scaling to a large-scale, framework dataset, we modeled lichen community response to air quality and climate gradients at 1416 forested 0.4 ha plots. Model development balanced polluted plots across elevation, forest type and precipitation ranges to isolate pollu...
متن کاملEpiphytic macrolichen communities along regional gradients in northern Norway
Question: What are the relative influences of human impact, macroclimate, geographic location and habitat related environmental differences on species composition of boreal epiphytic macrolichen communities? Location: Troms county in northern Norway. Methods: Detrended Correspondence Analysis revealed the main gradient structure in lists of epiphytic macrolichen species from deciduous forests. ...
متن کاملFungal Hyphal Dynamics in a Western Oregon Douglas-fir Stand
Total length and biomass of fungal mycelium in the soil of a young stand of second-growth Douglas-fir in the central Oregon Coast Range were estimated over 27 months with the agar-film technique. Mycelial mass was at maximum in fall and spring and significantly lower in summer. Melanized hyphae dominated other colors, averaging 66% of monthly litter and 73.7% of soil hyphal weight. The mycorrhi...
