In 1991 Pacific yew (Taxus brevifolia Nutt.) was reported as a new host for Phytophthora lateralis Tucker and Milbrath which is an aggressive root rot pathogen thought previously to be specific to Port-Orford-cedar. This study was designed to compare the pathogenicity of P. lateralis on the two hosts, and to...
Numerous managerial and organizational theorists have worked to
develop a set of concepts and theories that encapsulate the key elements of
leadership. Contemporary research links leadership to such matters as gender and
organizational mission or focus. The present study was undertaken in response to
a new approach to leadership theory...
Temperature profiles from boreholes on the Colorado Plateau of southeastern Utah have been examined for evidence of climate change. Because these boreholes penetrate layered sedimentary rocks with different thermal conductivities, Bullard plots (temperature versus integrated thermal resistance) are used to estimate background heat flow and surface temperature intercepts. Reduced temperatures,...

New research has identified flavonols as a class of phenolic compounds which can be manipulated by both vineyard and winery practices. These phenolic compounds are key quality components of wine, affecting sensory characteristics, wine color, and wine stability. Modification of the phenolic precursors in grapes occur during fermentation and aging...
