Culinary Rhubarb Production in North America: History and Recent Statistics

The West Nile virus: its recent emergence in North America.

West Nile fever emerged in New York in the summer of 1999 when seven people, several horses and thousands of wild birds died. It was soon established that the human disease and the mortality of birds were related. Continued surveillance detected West Nile virus in mosquitoes, birds, horses, small mammals, bats and humans, and has shown its spread to several northeastern states. These events con...

Recent Relative Sea-level Change in Eastern North America

Eigenanalysis of tide-gauge records between 1920 and 1983 in eastern North America reveals highly variable spatial and temporal patterns of relative sea-level change. Auxiliary data from numerical modeling suggest that much of the long wavelength (thousands of km) spatial patterns of sea-level change are due to post-glacial isostatic adjustment of the land surface. Filtering the isostatic compo...

Arthropods and biofuel production systems in North America

Biomass harvest may eventually be conducted on over 100 000 000 ha of US crop and forest lands to meet federally-mandated targets for renewable biofuels. Such largescale land use changes could profoundly impact working landscapes and the arthropod communities that inhabit them. We review the literature on dedicated biofuel crops and biomass harvest from forests to look for commonalities in arth...

Industrial Hemp in North America: Production, Politics and Potential

Most of the Western World banned the cultivation of Cannabis sativa in the early 20th century because biotypes high in ∆9-tetrahydrocannabinol (THC, the principal intoxicant cannabinoid) are the source of marijuana. Nevertheless, since 1990, dozens of countries have authorized the licensed growth and processing of “industrial hemp” (cultivars with quite low levels of THC). Canada has concentrat...
