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)
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)
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)
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)
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)
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)
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)
Predicting the perfect predator
Garlic mustard has become an invasive species in temperate forests across the United States, choking out native plants on forest floors and threatening ecosystem diversity. view more (2008-02-14)
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 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)
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)
Over time, an invasive plant loses its toxic edge
Like most invasive plants introduced to the U.S. from Europe and other places, garlic mustard first found it easy to dominate the natives. A new study indicates that eventually, however, its primary weapon - a fungus-killing toxin injected into the soil - becomes less potent. view more (2009-09-01)
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)
Changing climate may make 'super weed' even more powerful
Researchers at the University of Delaware have discovered a new reason why the tall, tasseled reed Phragmites australis is one of the most invasive plants in the United States. view more (2009-06-04)
Elevated CO2 in atmosphere weakens defenses of soybeans to herbivores
In research to be presented at the annual meeting of the American Society of Plant Biologists in Chicago (July 7-11, 2007), scientists will show that elevated CO2 may negatively impact the relationship between some plants and insects. view more (2007-07-09)
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)
Biocontrol Insect Exacerbates Invasive Weed
Biocontrol agents, such as insects, are often released outside of their native ranges to control invasive plants. But scientists in Montana have found that through complex community interactions among deer mice, native plants and seeds, the presence of an introduced fly may exacerbate the effects of the invasive plant it was meant to control. view more (2008-09-04)
New markers of climate change
A new way to monitor the effects of climate change on rainforests is being investigated at Cambridge University. Researchers are using biomarkers in the shape of epiphytes ('air-plants' which grow on other plants) to find out how their photosynthesis and water evaporation have been affected by climate change over the last 50 years. view more (2005-07-13)
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)
Milk cures plant disease
Research at Harper Adams University College has shown how spraying wheat plants with milk can help to cure mildew disease. South American research showed four years ago that milk could help in the fight against mildew disease on squash plants, and milk is used to treat this disease by some organic gardeners, as well as by grape vine growers in... view more...
