A comprehensive multi-disciplinary synthesis just published in Environmental Reviews reveals the urgent need for further investigation and policy development to address significant environmental, social and economic impacts of invasive alien species (IAS) and climate change. "Effects of climate change on the distribution of invasive alien species in Canada: a knowledge synthesis of range change prediction in a warming world" is the collaborative effort of a team of dedicated researchers at...

A recent analysis led by ecologist Bethany Bradley at the University of Massachusetts Amherst suggests that climate change predicted for the United States will boost demand for imported drought- and heat-tolerant landscaping plants from Africa and the Middle East. This greatly increases the risk that a new wave of invasives will overrun native ecosystems in the way kudzu, Oriental bittersweet and purple loosestrife have in the past, members of the international team say. The kudzu invasion...

Invading Species Threaten Texas Gulf Coast

The Asian Tiger Prawn, an invasive species in the Gulf of Mexico that can grow nearly a foot long and threatens native wild stocks, has been found on the Texas coast. The tiger prawns, native to the western Pacific, have been spreading along the Gulf Coast since 2006 and their numbers have increased this year. Shrimpers pulled the first one from Texas waters in June. So far shrimpers harvested three in Aransas Bay, one from Sabine Lake at the Louisiana Border and one from open waters about...

In an irony of nature, invasive species can become essential to the very ecosystems threatened by their presence, according to a recent discovery that could change how scientists and governments approach the restoration of natural spaces. Princeton University researchers report this month in the journal Proceedings of the Royal Society B evidence that destructive, non-native animals that have been deservedly maligned by conservationists the world over can take on important biological roles...

Not enough ships able to flush out invasive species before they reach port Invasive species have hitchhiked to the U.S. on cargo ships for centuries, but the method U.S. regulators most rely on to keep them out is not equally effective across coasts. Ecologists from the Smithsonian Environmental Research Center have found that ports on the East Coast and the Gulf of Mexico are significantly less protected than ports on the West Coast. Invaders are frequently introduced across oceans and...

Biological invasions, i.e. the spread of introduced, non-native species, not only serve as ecological model systems, but also bring out the importance of economic activities on ecological processes. Two recent books have shown the extent and variety of the interaction of economics with invasion science and also the variety of approaches to tackling these problems. Three researchers, lead by Mark Williamson from the University of York, England, argue in the latest issue of the open access...

Cities are generally regarded as hostile for wildlife and urbanization a dramatic form of destruction of natural habitats. Still, they are far from dead zones. Their biodiversity may even exceed that of surrounding landscapes, owing to heterogeneous environments and frequent localization in naturally rich areas that historically supplied diverse resources for their human inhabitants. "This is definitely the case of the city of Prague, Czech Republic", says the lead author Prof....

Varieties of long-lived plants that have been bred to produce fewer viable seed retain the potential to be invasive, despite claims to the contrary, and regardless do not usually 'breed true,' researchers conclude Cultivars of popular ornamental woody plants that are being sold in the United States as non-invasive are probably anything but, according to an analysis by botanical researchers published in the October issue of BioScience. Tiffany M. Knight of Washington University in St....

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...
