Latest Invasive species Stories
The Weed Science Society of America discusses the upcoming National Invasive Species Awareness Week (February 23-28) and identifies ways individuals can prevent the spread of invasive plants.
Some introduced (i.e. non-native) plants become abundant, threaten species richness and the well-functioning of ecosystems, the economy, or health (plant invasion).
In 1859 an Australian farmer named Thomas Austin released 24 grey rabbits from Europe into the wild because it "could do little harm and might provide a touch of home, in addition to a spot of hunting."

Plants in extreme desert environments develop effective strategies to compete for the area’s limited resources, according to new research out of the University of Arizona, published in the American Journal of Botany.
A University of Iowa researcher has discovered that a “Goldilocks” effect applies to the reproductive output of a tiny New Zealand snail—considered a troublesome species in many countries—that may one day help environmentalists control their spread.
The global market for ballast water treatment equipment was valued at nearly $1.4 billion in 2012 and is expected to reach $2.1 billion in 2013.
Among the most impressive ecological findings of the past 25 years is the ability of invasive plants to radically change ecosystem function.
Scientists unlock mysteries of invasive species by studying English sparrows which have spread to Kenya.
University of Toronto research has found that purple loosestrife – an invasive species that competes with native plants for light and nutrients and can degrade habitats for wildlife – has evolved extremely rapidly, flowering about three weeks earlier as it has spread to northern Ontario.
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...
