Germination and early growth of Ailanthus and tulip poplar in three levels of forest disturbance
Increasing rates of forest disturbance may provide greater opportunity for invasion of nonnative species, thereby altering the successional trajectory of native plant communities. In the easternExpand

Seed dispersal of the non-native invasive tree Ailanthus altissima into contrasting environments
Ailanthus altissima has a long history of invasion in urban areas and is currently spreading into suburban and rural areas in the eastern U.S. The objectives of our study were to (1) determineExpand

Seasonal Trends in Separability of Leaf Reflectance Spectra for Ailanthus altissima and Four Other Tree Species
The separability of Ailanthus altissima (tree of heaven) from four native species was investigated using spectral reflectance measurements (350 to 2,500 nm) of leaves collected from 13 May through 24Expand

Seed-bank characteristics in mixed-mesophytic forest clearcuts and edges: Does "edge effect" extend to the seed bank?
Little is known about the seed banks of mixed-mesophytic forest clearcuts or their associated forest edges. Seed banks were described and compared to better understand how seed density, speciesExpand

Spatial patterns of female Ailanthus altissima across an urban-to-rural land use gradient
Ailanthus altissima is an invasive, dioecious deciduous tree common at the interface between urban and rural areas in the mid-Atlantic region, U.S.A. To examine spatial patterns of abundance andExpand

Eupatorium rugosum (Asteraceae) flowering as an indicator of edge effect from clearcutting in mixed-mesophytic forest
Abstract We analyzed flowering of white snakeroot (Eupatorium rugosum) as an indicator of edge effect from recent silvicultural clearcutting in mixed-mesophytic forest in northcentral West Virginia.Expand
