Microsatellite markers for eastern hemlock (Tsuga canadensis).

Effect of Daily Minimum Temperature on Photosynthesis in Eastern Hemlock (Tsuga canadensis L.) in Autumn and Winter

Terrain and Landform Influence on Tsuga canadensis (L.) Carrière (Eastern Hemlock) Distribution in the Southern Appalachian Mountains

We examined the relationships between hemlock distribution and abundance and terrain attributes for the Coweeta Basin in the southern Appalachian Mountains. Field measurements were combined with GIS mapping methods to develop predictive models of abundance and distribution of Tsuga canadensis (L.) Carrière (eastern hemlock) and evaluate the co-occurrence of Rhododendron maximum L. (rosebay) and...

Vertical Stratification and Co-Occurrence Patterns of the Psocoptera Community Associated with Eastern Hemlock, Tsuga canadensis (L.) Carrière, in the Southern Appalachians

Of the more than 300 species of Psocoptera described in North America, 44 species have been documented on eastern hemlock, Tsuga canadensis (L.) Carrière, in the southern Appalachians. However, the distribution and co-occurrence patterns of these species throughout the tree canopy are unknown. This study was initiated to evaluate specimen abundance, species richness and species composition amon...

Restoration of Damaged Stands : Dealing with the

Eastern hemlock (Tsuga canadensis (L.) Carr.) is an evergreen conifer that is widely dispersed in the northeastern United States. Loss of the hemlock component in the eastern forest due to the introduced hemlock woolly adelgid (Adelges tsugae) will have long-term consequences for terrestrial and aquatic ecosystems. Some of the functional attributes of hemlock (vertical structure diversity, ever...

Orientation behavior of the predator Laricobius nigrinus (Coleoptera: Derodontidae) to hemlock woolly adelgid and host tree odors in a multi-chambered olfactometer.

We studied the adult ambulatory response of the predator, Laricobius nigrinus Fender (Coleoptera: Derodontidae), to odors from its prey, Adelges tsugae Annand, the hemlock woolly adelgid, and foliage of hemlock woolly adelgid, host hemlocks (Tsuga spp.), and other conifers. Both the predator and hemlock woolly adelgid are apparently native to western North America, but the predator is being re...
