Invasive plant species have long had a reputation as being bad for a new ecosystem when they are introduced. Stan Harpole, assistant professor of ecology, evolution and organismal biology at Iowa State University, is founding organizer of a team of more than 70 researchers working at 65 sites worldwide that tested that assumption. They wanted to know if it is true that problematic invasive species often spread widely in their new habitats because they don't encounter predators or diseases...

Conservation and fishing groups are calling on the federal government to improve outdated laws and prevent the next invasion WASHINGTON, Feb. 28, 2011 /PRNewswire-USNewswire/ -- Asian carp were allowed into this country under a law governing animal imports that was passed in 1900, and which has remained unchanged, despite a drastically different global trade reality. As two species of Asian carp, bighead and silver, knock at the door of the Great Lakes, conservation and fishing groups are...

Non-native insects and diseases can spread by traveling on wood packaging and other untreated wood ARLINGTON, Va., Feb. 18, 2011 /PRNewswire-USNewswire/ -- A collaboration of diverse interests aimed at addressing the threat of non-native insects and diseases is urging the United States Department of Agriculture (USDA) to subject wood packaging material from Canada to the same requirements other countries must follow for this material before it can enter the country. Currently, the...

As yet another invasive animal becomes established, environmental groups call on the federal government to screen the trade of imported animals and prevent the next problem invasion WASHINGTON, Feb. 14, 2011 /PRNewswire-USNewswire/ -- A large, non-native lizard called the black and white tegu has become established in Florida. Like the Burmese python, one of the state's most well-known invasive animals, the lizard is pushing out many of Florida's native animals, including some threatened...

A team of scientists has discovered that human-introduced, invasive species of plants can have positive ecological effects. Tomás Carlo, an assistant professor of biology at Penn State University, and Jason Gleditsch, a graduate student in the Department of Biology, have studied how invasive fruiting plants affect ecosystems and how those effects, contrary to prevailing ideas, sometimes can be beneficial to an ecological community. The team's research, which will be published in the...

Invasive plant species present a serious environmental, economic and social problem worldwide as their abundance can lead to lost native biodiversity and ecosystem functions, such as nutrient cycling. Despite substantial research, little is known about why some species can dominate new habitats over native plants that technically should have the advantage. A common but rarely tested assumption is that these plants are more abundant in introduced versus native communities, because they are...

Collapse of Earth's marine life 378 to 375 million years ago holds key An influx of invasive species can stop the dominant natural process of new species formation and trigger mass extinction events, according to research results published Dec. 29 in the journal PLoS ONE. The study of the collapse of Earth's marine life 378 to 375 million years ago suggests that the planet's current ecosystems, which are struggling with biodiversity loss, could meet a similar fate. Although Earth has...

Animals and plants introduced from foreign habitats may not seem harmful and can coexist with native species for decades, according to a European study published Monday. Species that are taken away from their natural predators and placed elsewhere can disrupt native species in their new habitats, and scientists say the problem is already costing Europe $16 billion per year. The study, published in the US Proceedings of the National Academy of Sciences, which is likely to hold true for other...

While Asian carp, gypsy moths and zebra mussels hog invasive-species headlines, many invisible invaders are altering ecosystems and flourishing outside of the limelight. A study by Elena Litchman, Michigan State University associate professor of ecology, sheds light on why invasive microbial invaders shouldn't be overlooked or underestimated. "Invasive microbes have many of the same traits as their larger, 'macro' counterparts and have the potential to significantly impact terrestrial and...

The Pacific Oyster (Crassostrea gigas), is the native oyster of the Pacific coast of Korea, Japan and China. It has been introduced to North America, especially in Puget Sound, Washington, and to the Australian states of Tasmania and South Australia. It is an important commercial harvest in all of these places, as well as New Zealand where the Pacific oyster has replaced the native rock oyster, Crassostrea glomerata, as the main commercial species. The Pacific oyster is an invasive species...
