Germination and early growth of Ailanthus and tulip poplar in three levels of forest disturbance

• Nathan L. Kota, Rick E. Landenberger, James B. McGraw
• Biological Invasions
• 2006

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 eastern… (More)

Seed dispersal of the non-native invasive tree Ailanthus altissima into contrasting environments

• Rick E. Landenberger, Nathan L. Kota, James B. McGraw
• Plant Ecology
• 2006

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) determine… (More)

Image restoration based on multiscale relationships of image structures

• Tomas Brandtberg, James B. McGraw, Timothy A. Warner, Rick E. Landenberger
• IEEE Trans. Geoscience and Remote Sensing
• 2003

Aerial photographs sometimes suffer from artifacts caused by vignetting effects and changing topographic sun–canopy–sensor geometry. In this paper, we present an empirical image restoration method… (More)

Spatial patterns of female Ailanthus altissima across an urban-to-rural land use gradient
