Assessing the Potential Impacts to Riparian Ecosystems Resulting from Hemlock Mortality in Great Smoky Mountains National Park
Hemlock Woolly Adelgid (Adelges tsugae) is spreading across forests in eastern North America, causing mortality of eastern hemlock (Tsuga canadensis [L.] Carr.) and Carolina hemlock (Tsuga caroliniana Engelm.). The loss of hemlock from riparian forests in Great Smoky Mountains National Park (GSMNP) may result in significant physical, chemical, and biological alterations to stream environments. ...
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 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...
متن کاملSeedling insensitivity to ozone for three conifer species native to Great Smoky Mountains National Park.
Field symptoms typical of ozone injury have been observed on several conifer species in Great Smoky Mountains National Park, and tropospheric ozone levels in the Park can be high, suggesting that ozone may be causing growth impairment of these plants. The objective of this research was to test the ozone sensitivity of selected conifer species under controlled exposure conditions. Seedlings of t...
