Invasive species on the march: variable rates of spread set current limits to predictability
Whether for introduced muskrats in Europe or oak trees in the United Kingdom, zebra mussels in United States lakes or agricultural pests around the world, scientists have tried to find new ways of controlling invasive species by learning how these animals and plants take over in new environs.   view more (2009-09-18)

Invasive Grass May Impede Forest Regeneration
The nonnative invasive grass Microstegium vimineum may hinder the regeneration of woody species in southern forests.   view more (2007-04-10)

Farmed salmon could become an invasive species in forest streams
Ever since the Norwegians expanded commercial farming of salmon in the 1960s, the industry has continued to rapidly grow worldwide.   view more (2007-03-09)

Invasive species alter habitat to their benefit
When scientists study habitats that alien species have invaded, they usually find predictable patterns. The diversity of native species declines, and changes occur in natural processes such as nutrient cycling, wildfire frequency and the movement of water through the system.   view more (2006-08-10)

Species detectives track unseen evolution
New species are evading detection using a foolproof disguise - their own unchanged appearance. Research published in the online open access journal, BMC Evolutionary Biology, suggests that the phenomenon of different animal species not being visually distinct despite other significant genetic differences is widespread in the animal kingdom.   view more (2007-07-19)

Ecologists give evidence to climate change inquiry
The UK should use its presidency of the G8 and EU to move forward international action to analyse future risks due to climate change and develop and implement evidence-based adaptation strategies for coping with the immediate impacts of climate change, the British Ecological Society has urged. Giving evidence to the House of Commons Environment,... view more... (2004-12-08)

Invasive species harms native hardwoods by killing soil fungus
An invasive weed that has spread across much of the U.S. harms native maples, ashes, and other hardwood trees by releasing chemicals harmful to a soil fungus the trees depend on for growth and survival.   view more (2006-04-26)

Invasive species threaten critical habitats, oyster among victims
A study of oyster reefs in a once-pristine California coastal estuary found them devastated by invasive Atlantic Coast crabs and snails, providing new evidence of the consequences when human activities move species beyond their natural borders.   view more (2009-07-20)

Queen's marine biologist investigates aliens beneath the waves
Queen's University Belfast is appealing for help from the public in looking at ways to detect and stop the spread of marine aliens.   view more (2008-06-17)

Northwestern United States could face more tamarisk invasion by century's end
If the future warming trends that scientists have projected are realized, one of the country's most aggressive exotic plants will have the potential to invade more U.S. land area, according to a new study published in the current issue of the journal Invasive Plant Science and Management.   view more (2009-09-16)

Not 1, but 2 kinds of males found in the invasive round goby
Scientists have found the existence of two types of males of a fiercely invasive fish spreading through the Great Lakes, which may provide answers as to how they rapidly reproduce.   view more (2009-06-16)

Microbial stowaways: Are ships spreading disease?
Ships are inadvertently carrying trillions of stowaways in the water held in their ballast tanks. When the water is pumped out, invasive species could be released into new environments. Disease-causing microbes could also be released, posing a risk to public health, according to an article in the May issue of Microbiology Today.   view more (2008-05-29)

Protein predicts development of invasive breast cancer in women with DCIS, Penn study shows
Women with ductal carcinoma in situ (DCIS) who exhibit an overexpression of the protein HER2/neu have a six-fold increase in risk of invasive breast cancer.   view more (2009-05-22)

Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)
The biodiversity of a community can affect its functional properties, such as its productiveness or its ability to resist invasion by exotic species. Many grass species host fungi in their leaves that can render them more resistant to herbivory, drought, and competition. In a forthcoming issue of Ecology Letters, Rudgers, Koslow and Clay... view more... (2003-12-10)

Introduced marine species get larger in the invaded region
The transport of species outside their native region through human activities has often had a dramatic impact on the ecosystems into which these species are introduced and on the surrounding economies. The consequences of introduction for the introduced species itself, including changes in body size and shape, are less recognized. Prior studies of... view more... (2003-08-13)

All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon species. In the June issue of Ecology Letters, Smith... view more... (2003-05-22)

Mussels evolve quickly to defend against invasive crabs
Scientists at the University of New Hampshire (UNH) have found that invasive crab species may precipitate evolutionary change in blue mussels in as little as 15 years.   view more (2006-08-11)

Disease opened door to invading species in California
Plant and animal diseases can play a major and poorly appreciated role in allowing the invasion of exotic species, which in turn often threatens biodiversity, ecological function and the world economy, researchers say in a new report.   view more (2007-03-13)

Study predicts when invasive species can travel more readily by air
Global airlines be forewarned: June 2010 could be a busy month for invasive plants, insects and animals seeking free rides to distant lands.   view more (2009-02-26)
