Indigenous Corn Propagation Project

The primary constituency of the Dream of Wild Health is the American Indian community in the Upper Midwest, including both the urban Indian community in the Twin Cities of Minneapolis and St. Paul and the reservation communities in the region. Dream of Wild Health had rare heirloom corn seeds that needed propagation. In April of 2006, Dream of Wild Health entrusted Professor Bud Markhart in University of Minnesota's Department of Horticultural Science with nine varieties of indigenous corn seed. In May of 2006 Karin Kettering photographed the supplied seed and sampled a portion of each variety along with a control organic sweet corn from Seed Savers Inc. Many varieties were successfully propagated.Prepared in partnership with Peta Wakan Tipi by the Community Assistantship Program (CAP), administered by the Center for Urban and Regional Affairs (CURA) at the University of Minnesota

Salinity tolerance ecophysiology of Equisetum giganteum in South America: a study of 11 sites providing a natural gradient of salinity stress

In river valleys of the world's driest desert (The Atacama of South America) large stands of giant horsetail (Equisetum giganteum) are found to tolerate soil water salinity up to at least half that of seawater. The roots selectively exclude Na and take-up K in response to salinity while stomatal conductances and photochemical efficiency of Photosystem II remain unaffected
