Variation in seed dispersal along an elevational gradient in Great Smoky Mountains National Park
Seed dispersal by ants is ecologically important and geographically widespread as 20–50% of all herbaceous species in eastern deciduous forests are dispersed by ants, but we know little about how or why such interactions vary geographically. In this paper, we examined variation in seed dispersal by ants along an extensive elevational gradient (256–2025 m) in the Great Smoky Mountains National P...
متن کاملImpacts of climatic and atmospheric changes on carbon dynamics in the Great Smoky Mountains National Park.
We used the Dynamic Land Ecosystem Model (DLEM) to estimate carbon (C) storage and to analyze the impacts of environmental changes on C dynamics from 1971 to 2001 in Great Smoky Mountain National Park (GRSM). Our simulation results indicate that forests in GRSM have a C density as high as 15.9kgm(-2), about twice the regional average. Total carbon storage in GRSM in 2001 was 62.2Tg (T=10(12)), ...
متن کاملA Multivariate Analysis of Forest Communities in the Western Great Smoky Mountains National Park
An integrated sequence of multivariate techniques was applied to the vegetation of the western Great Smoky Mountains National Park. Included in the sequence were hierarchial classification, detrended correspondence analysis and multiple discriminant analysis. Based on the importance of landform in previous research, a system of topographical quantification was developed and also used in the cla...
متن کاملCercophora rubrotuberculata sp. nov., a new pyrenomycete from the Great Smoky Mountains National Park.
An interesting wood-inhabiting pyrenomycete was discovered while collecting for the All Taxa Biodiversity Inventory currently being conducted in the Great Smoky Mountains National Park. This species is unique in possessing superficial ascomata with reddish tubercles and ascospores that develop an apical swollen brown cell and a long, basal hyaline cell. Because these ascospore characters fit th...
