According to the Weed Science Society of America, weeds threaten the native vegetation growing along millions of miles of our nationâs waterways -- undermining the ability of these "riparian" areas to store and filter water and to prevent or moderate flooding. Lawrence, KS (PRWEB) December 05, 2011 This year flooding has ravaged thousands of homes and businesses in communities across the U.S. And scientists say the prevalence of invasive weeds is one of the factors that may be...

Non-chemical method matches herbicides for managing weeds Traditionally addressed through hand-weeding and/or herbicide application, controlling weeds is one of most costly operations in nursery production. Increased labor costs have made hand-weeding prohibitive as the sole method of weed control, and although herbicides may be effective and less expensive, non-target herbicide loss can be as high as 86% and can harm the environment. To address the economic and environmental impact of...

Evolutionary traps, invasive yellow starthistle´s favorable response to carbon dioxide and plant breeding for harmony between agriculture and the environment Evolutionary traps in human-dominated landscapes A study published in the September issue of Ecology looks at how human activities can diminish the usefulness of an ornamental trait, such as colorful feathers, as a signal of fitness. Cardinals, for example, need carotenoids in their diet to produce their red plumage; brilliant...

Road maintenance may accidentally spread the seeds of invasice plants, according to Penn State researchers. "The road graders that are used during these operations can act like a plow, pushing seeds along the road," said Emily Rauschert, senior project associate and applied ecologist in crop and soil sciences. "They can pick up seeds of an invasive grass and spread them several orders of magnitude further than the natural dispersal." The researchers created a computer simulation based on...
