Invasive plant outcompeted by its native ancestors
Invasive alien species are one of the greatest threats to global biodiversity. Part of their success may be due to rapid evolutionary changes when invaders adapt to the novel conditions in their invaded habitats. Invasive plants, in particular, are believed to double-profit from a loss of their natural enemies and subsequent evolution of less... view more... (2004-03-18)
Gardeners urged to help stop spread of invasive plants
Invasive alien plants are causing havoc in our natural landscape, but gardeners can play a key part in stopping their spread. That`s the view of Imperial College Wye which will be exhibiting at this year`s Chelsea Flower Show, opening 20 May. The College stand (LL23) will outline the threat caused by alien or non-native plants introduced... view more... (2002-05-09)
Invasives threaten salmon in Pacific Northwest
Many native fishes in the Pacific Northwest are threatened or endangered, notably salmonids, and hundreds of millions of dollars are expended annually on researching their populations and on amelioration efforts. view more (2009-03-02)
Biological invasions can begin with just 1 insect
A new study by York University biologists Amro Zayed and Laurence Packer has shown that a lone insect can initiate a biological invasion. view more (2007-09-12)
Attack of the invasive garden ants
An ant that is native to Eurasia is threatening to become the latest in a procession of species to invade Europe, as a result of inadvertent human introduction. Research published in the online open access journal BMC Biology demonstrates that the invasive garden ant, Lasius neglectus, which is a threat to native species, may already be more... view more...

Woody and aquatic plants pose greatest invasive threat to China
Although China currently has fewer invasive woody plants than the United States, China's potential for invasion by nonnative trees and shrubs is high, according to an article in the May 2008 issue of BioScience. view more (2008-05-01)
Scientist Names Top Five Invasive Plants Threatening Southern Forests in 2009
U.S. Forest Service Southern Research Station (SRS) Ecologist Jim Miller, Ph.D., one of the foremost authorities on nonnative plants in the South, today identified the invasive plant species he believes pose the biggest threats to southern forest ecosystems in 2009. view more (2009-01-13)
Reservoirs may accelerate the spread of invasive aquatic species, researchers say
Just as disturbance makes a landscape susceptible to invasion by alien plant species, the construction of reservoirs around the globe could be contributing to the accelerating spread of exotic aquatic species. view more (2005-05-31)
National assessment done on potential invasive snail and slug pests in US
A collaborative team led by a University of Hawai'i at Manoa researcher has published the first-ever assessment of snail and slug species that are of potential threat to the nation's agriculture industry and the environment, should they ever be introduced in the U.S. view more (2009-07-31)
Climate change opens new avenue for spread of invasive plants
Plants that range northward because of climate change may be better at defending themselves against local enemies than native plants. view more (2008-11-20)
Will Europe at last unite to combat thousands of alien invaders?
Europe's borders have been breached by thousands of plants and animal species from other parts of the world: from the American mink to the New Zealand flatworm. The invaders feed on, hybridise with, parasitise and out-compete native species. view more (2009-04-06)
Alien plants attack using 'resource conservation' as weapon, researchers say
One of the most serious and least understood threats to the world's ecosystems is the problem of invasive species-exotic plants, animals and other organisms that are brought into habitats and subsequently spread at a rapid rate, often replacing native species and reducing biodiversity. view more (2007-05-02)
1-YEAR OUTCOMES AFTER INVASIVE VS NON-INVASIVE HEART-DISEASE TREATMENT (P 9)
Previously, the Fast Revascularisation during Instability in Coronary Artery Disease (FRISC) II investigators showed that the drug dalteparin lowered the risk of death, myocardial infarction, and need for revascularisation in patients with unstable coronary artery disease. The question was raised, however, of whether myocardial infarction was a... view more... (2000-06-28)
Smithsonian identifies invasive crab species in Panama Canal expansion area

For the first time it is now possible to get a comprehensive overview of which alien species are present in Europe, their impacts and consequences for the environment and society. view more (2008-11-21)
Sea Grant warns of dumping seafood
In its latest outreach campaign, MIT Sea Grant has developed an educational pamphlet to encourage people not to release or dump live and fresh seafood and seafood waste into the wild. view more (2006-06-22)
Invasive plants prefer disturbance in exotic regions over home regions
One of the most invasive exotics in the western United States, the yellow starthistle, is successful both at "invasion" in non-native areas and "colonization" in native ones. view more (2006-07-27)
Nitrogen research shows how some plants invade, take over others
Biologists know that when plants battle for space, often the actual battle is for getting the nitrogen. view more (2009-07-07)
