LICHENS OF PINE HILL, A PERIDOTITE OUTCROP IN EASTERN NORTH AMERICA

North-South Variation in the Response of the Pine Engraver (Coleoptera: Scolytidae) to Lanierone and lpsdienol in Eastern North America’

d J. Entomol. Sci. 38(3): 468-476 (July 2003) Abs t rac t Lindgren multiple-funnel traps were used to evaluate the response of the pine engraver, Ips phi (Say), to the pheromones lanierone and ipsdienol, in Wisconsin and in southern Appalachia (western North Carolina and northern Georgia). As in Wisconsin, the attraction of 1. pini to ipsdienol-baited traps in southern Appalachia was strongly s...

Comparative phylogeography of unglaciated eastern North America.

Regional phylogeographical studies involving co-distributed animal and plant species have been conducted for several areas, most notably for Europe and the Pacific Northwest of North America. Until recently, phylogeographical studies in unglaciated eastern North America have been largely limited to animals. As more studies emerge for diverse lineages (including plants), it seems timely to asses...

Distributions of exotic plants in eastern Asia and North America.

Although some plant traits have been linked to invasion success, the possible effects of regional factors, such as diversity, habitat suitability, and human activity are not well understood. Each of these mechanisms predicts a different pattern of distribution at the regional scale. Thus, where climate and soils are similar, predictions based on regional hypotheses for invasion success can be t...

Biogeographic synthesis of secondary succession rates in eastern North America

In the Eastern Deciduous Forest (EDF) of North America, over a century of studies of secondary succession has produced a standard descriptive model of the transition of croplands to forest, namely colonization by annual herbs, followed by dominance by perennial herbs and grasses, and subsequent stages of woody species colonization and dominance (Oosting, 1942; Keever, 1950; Bazzaz, 1963). Addit...
