Ecology of West Nile Virus in North America

The introduction, dispersal and establishment of West Nile virus in North America were reviewed, focusing on factors that may have enhanced receptivity and enabled the invasion process. The overwintering persistence of this tropical virus within temperate latitudes was unexpected, but was key in the transition from invasion to endemic establishment. The cascade of temporal events allowing spora...

Ecology and management of the soybean aphid in North America.

The soybean aphid, Aphis glycines Matsumura, has become the single most important arthropod pest of soybeans in North America. Native to Asia, this invasive species was first discovered in North America in July 2000 and has rapidly spread throughout the northcentral United States, much of southeastern Canada, and the northeastern United States. In response, important elements of the ecology of ...

Fire and Avian Ecology in North America: Process Influencing Pattern

We summarize the fi ndings from 10 subsequent chapters that collectively review fi re and avian ecology across 40 North American ecosystems. We highlight patterns and future research topics that recur among the chapters. Vegetation types with long fi re-return intervals, such as boreal forests of Canada, forests at high elevations, and those in the humid Pacifi c Northwest, have experienced the...

Late Glacial Landscape Ecology in Central North America

The transition from full glacial to interglacial conditions along the southern margin of the Laurentide ice sheet resulted in dramatic changes in landscapes and biotic habitats. Strata and landforms resulting from the Wisconsin Episode of glaciations in the area directly west of Lake Superior indicate a context for late Pleistocene biota (including human populations) connected to ice margins, p...
