Latest Invasive species Stories
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.
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.
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.
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.
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.
Cities are generally regarded as hostile for wildlife and urbanization a dramatic form of destruction of natural habitats.
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.
Researchers have found that a species invasion that starts at the upstream edge of its range may have a major advantage over downstream competitors, at least in environments with a strong prevailing direction of water or wind currents.
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.
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...
