Site factors determining epiphytic lichen distribution in a dieback-affected spruce-fir forest on Whiteface Mountain, New York: stemflow chemistry
Epiphytic lichen diversity in a dieback-affected forest of red spruce (Picea rubens Sarg.) and balsam fir (Abies balsamea (L.) Mill.) on Whiteface Mountain, New York, U.S.A., was higher on dead compared with living trees and on fir compared with spruce. Diversity differed more between living and dead spruce than between living and dead fir. Cover of all lichen species that occurred on more than...
متن کاملCommunity and population dynamics of spruce-fir forests on Whiteface Mountain, New York: recent trends, 1985-2000
We remeasured two sets of permanent plots in old-growth, spruce–fir forests on Whiteface Mountain to quantify ongoing vegetation dynamics at sites impacted by spruce decline. One set of plots was a stratified random sample of the vegetation in a subalpine watershed (Baldwin site). The other was selected to represent forest conditions in a high-elevation subset of the spruce–fir forest (Esther s...
متن کاملNitrogen availability and forest productivity along a climosequence on Whiteface Mountain, New York
We studied broadleaf and needle-leaf forests along an elevation gradient (600–1200 m) at Whiteface Mountain, New York, to determine relationships among temperature, mineral N availability, and aboveground net primary productivity (ANPP) and controls on the latter two variables. We measured net N mineralization during the growing season, annual litterfall quantity and quality, aboveground woody ...
متن کاملRestoration of a Rocky Mountain Spruce-Fir Forest: Sixth-Year Engelmann Spruce Seedling Response With or Without Tree Shelter Removal
This paper presents results following 6 growing seasons of a project designed to examine the use of tree shelters as a means to provide initial shade for planted Engelmann spruce seedlings. Seedlings were planted in 1996 on a 48-ha (119-ac) high-elevation site with different colors of tree shelters providing various degrees of shading. A control treatment, consisting of shading using debris wit...
متن کاملStomatal Frequency, Distribution, and Needle Hydrophobicity in Cloud Forest Spruce and Fir, Southern Appalachian Mountains
from UCLA and was formerly a professor at the University of Wyoming. His research focuses on the adaptations of plants living in harsh and extreme environments, with a current focus on global change impacts. Current projects include studies of the global occurrence of the alpine treelines and the impacts of episodic, extreme events (e.g. hurricanes) on barrier island ecosystems. Based on the ad...
