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)
UGA study reveals ecosystem-level consequences of frog extinctions
Streams that once sang with the croaks, chirps and ribbits of dozens of frog species have gone silent. They're victims of a fungus that's decimating amphibian populations worldwide. view more (2008-10-17)
Unlocking genome of world's worst insect pest
Scientists from CSIRO and the University of Melbourne in Australia, and the Baylor College of Medicine in Houston, Texas, are on the brink of a discovery which will facilitate the development of new, safe, more sustainable ways of controlling the world's worst agricultural insect pest - the moth, Helicoverpa armigera. view more (2008-06-18)
Can we keep the cap on transgene escape?
Molecular strategies are being developed to impede the escape of transgenes from transgenic crops into wild relatives, which might become invasive upon acquiring transgenic traits such as resistance to pests or herbicides. For example, to impede escape through pollen, a transgene could be inserted into chloroplast DNA, which in many crops is... view more... (2004-02-24)
Smithsonian scientists find evidence that could rewrite Hawaii's botanical history
Scientists at the Smithsonian Institution have discovered data that suggests one of Hawaii's most dominant plants, Metrosideros, has been a resident of the islands far longer than previously believed. view more (2008-04-16)
Insurgental Biological Warfare Against Gipsy Moth
Specialists of the Institute of Taxonomy and Ecology of Animals (Siberian Branch, Russian Academy of Sciences) investigate peculiarities of struggle against Asian populations of Gipsy moth - one of the most widespread and economically significant forest pests. The methods applied in the North America and Europe do not work with Asian populations... view more... (2005-04-29)
Predetermined winners and losers in the Ice Age extinction game
The Quaternary ice ages caused severe decimation of the European tree flora. Of the diverse pre-Ice Age tree flora only a minority of the genera are still widespread in Europe. Most of the remainder have been lost altogether from the European flora and now only occurs in Asia and/or North America, although some persist as relicts in southern... view more... (2003-07-02)
Why eating less can help the environment
An estimated 19 percent of total energy used in the USA is taken up in the production and supply of food. Currently, this mostly comes from non-renewable energy sources which are in short supply. view more (2008-07-24)
New paper examines dams' effects on California salmon
Spring-run Chinook salmon and other fish in the rivers of California's Central Valley could be harmed by more water-storage dams, according to researchers at Duke University and the National Oceanic and Atmospheric Administration. view more (2007-09-25)
MSU study: Girls have harder time than boys adjusting in language-learning environment
Girls who don't share a common language may have more difficulty adjusting socially than boys, according to surprising new Michigan State University research looking at language acquisition among young children. view more (2008-10-07)
AIDS discovered in wild chimpanzees
Although the AIDS virus (HIV-1) entered the human population through chimpanzees, scientists have long believed that chimpanzees don't develop AIDS. view more (2009-07-23)
New CU-Boulder study shows diversity decreases chances of parasitic disease
A new University of Colorado at Boulder study showing that American toads who pal around with gray tree frogs reduce their chances of parasitic infections known to cause limb malformations has strong implications for the benefits of biodiversity on emerging wildlife diseases. view more (2008-10-22)
Habitat loss and reserve network selection
What is the minimum combination of areas needed to protect at least one population of every species in a region? - This is a problem commonly addressed when aiming at cost-effective reserve networks. However, because the stress on reserve cost, the properties of the reserve-network for species persistence are often overlooked, typically resulting... view more... (2003-07-02)
Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)
Populations of several European passerines that winter south of the Sahara have undergone a marked decline. The causes of negative population trends are largely unknown, but ecological conditions during winter in Africa may have carry-over effects during northward spring migration and reproduction. In the January issue of Ecology Letters, Saino,... view more... (2003-12-10)
Princeton-led team finds secret ingredient for the health of tropical rainforests
A team of researchers led by Princeton University scientists has found for the first time that tropical rainforests, a vital part of the Earth's ecosystem, rely on the rare trace element molybdenum to capture the nitrogen fertilizer needed to support their wildly productive growth. view more (2008-12-10)
Migratory bird struggles with climate – pied flycatchers lay their eggs too late
They try very hard, but pied flycatchers are not able to adapt sufficiently to the climate change in Western Europe. Dutch ecologists state this in Nature's issue of May 17 2001. Spring in Western Europe warmed up during the past 20 years and became increasingly ‘early’. However, the migratory flycatchers are still arriving at the same... view more... (2001-05-15)
Ecological communities suffer dramatic changes when non-native species are introduced by humans!
Ecological communities suffer dramatic changes when non-native species are introduced by humans. Such introductions have been documented in hundreds of locations and appear to be common in marine and island habitats. One of the best-studied cases of a species that suddenly appeared in the New England intertidal, and subsequently spread rapidly... view more... (2002-07-11)
Size does matter when choosing a mate
The difference in size between males and females of the same species is all down to the battle for a mate, according to a study of shorebirds published by British scientists today (August 9 2004). The findings, published in the Proceedings of the National Academy of Sciences, are the first explanation for a rule identified over forty years ago by... view more... (2004-08-09)
Abandoned farmlands are key to sustainable bioenergy
Biofuels can be a sustainable part of the world's energy future, especially if bioenergy agriculture is developed on currently abandoned or degraded agricultural lands, report scientists from the Carnegie Institution and Stanford University. view more (2008-06-24)
Iowa State professor's research shows Midwest forests losing diversity, complexity
Forests in the nation's Upper Midwest have changed greatly since the time of the early settlers. And more changes may be coming. view more (2007-10-17)
