Details of the lifestyle of mink, which escaped from fur farms and now live wild in the UK, have been revealed through analysis of their whiskers. Research led by the University of Exeter reveals more about the diet of this invasive species and provides a clue to its whereabouts. There are now plans to use the findings to eradicate it from environments where it can be devastating to native species. http://www.physorg.com/news180784602.html Biology Wed, 23 Dec 2009 10:10:04 EST news180784602 Five giant non-native snake species would pose high risks to the health of ecosystems in the United States should they become established here, according to a U.S. Geological Survey report released today. http://www.physorg.com/news174665310.html Biology Tue, 13 Oct 2009 16:00:02 EST news174665310 The first experiences with exotic species in the Basque Country, and alternative to Pinus radiata, were undertaken in 1957, concretely in Laukiz, Lezama and Alonsotegui (Muro, 1975) where the eucalyptus, amongst other forest species, was introduced. The expansion of rapid growth plantations such as those of eucalyptus came about in order to meet the needs of the growing paper pulp industry. Blights and diseases arose as one of the main threats to the plantations based on non-native species (Wingfield, 2003; Old et al., 2003). http://www.physorg.com/news173354886.html Biology Mon, 28 Sep 2009 11:30:03 EST news173354886 In the late 1920s, people intentionally introduced birds known as Japanese white-eyes into Hawaiian agricultural lands and gardens for purposes of bug control. Now, that decision has come back to bite us. A recent increase in the numbers of white-eyes that live in old-growth forests is leaving native bird species with too little to eat, according to a report published online on September 17th in Current Biology. The findings show that introduced species can alter whole communities in significant ways and cause visible harm to the birds that manage to survive. http://www.physorg.com/news172409454.html Biology Thu, 17 Sep 2009 12:32:00 EST news172409454 (AP) -- A year after they launched a nationwide search for dwindling native ladybugs, New York researchers are breeding colonies of them from insects found by citizen scientists in Oregon and Colorado. http://www.physorg.com/news171307054.html Biology Fri, 04 Sep 2009 18:18:01 EST news171307054 (PhysOrg.com) -- The rainbow smelt, an invasive fish that threatens native species such as walleye and perch, may soon be feeling the heat -- literally. http://www.physorg.com/news168190094.html Space & Earth Thu, 30 Jul 2009 16:40:01 EST news168190094 (AP) -- Imported insects have been deployed as foot soldiers in the fight against invasive bugs and plants that cause billions of dollars in damage each year. But some of those imports are proving to be pests themselves that upset the balance of nature and threaten native species. http://www.physorg.com/news167407763.html Biology Tue, 21 Jul 2009 15:20:02 EST news167407763 (AP) -- Two years after an invasive mussel was first discovered at Lake Mead, the population has firmly established itself and gone on a breeding binge, with numbers soaring into the trillions. http://www.physorg.com/news167163370.html Biology Sat, 18 Jul 2009 19:40:01 EST news167163370 (AP) -- One by one, seven slithering Burmese pythons were dumped into a snake pit surrounded by 400 feet of reinforced fence at the Savannah River Ecology Lab in South Carolina. http://www.physorg.com/news165079638.html Biology Wed, 24 Jun 2009 21:00:01 EST news165079638 When the sun rides low on the horizon and winter chills wrap us all in down and fleece, global trade brings blueberries from South America, oranges from Israel. But trade in exotic goods also comes with significant local economic costs, explains Charles Perrings, professor of environmental economics at Arizona State University. http://www.physorg.com/news153832653.html Space & Earth Sat, 14 Feb 2009 11:19:16 EST news153832653 (PhysOrg.com) -- Keeping water vole and mink populations apart is vital if efforts to reintroduce water voles, one of Britain`s most endangered mammals, are to be successful. http://www.physorg.com/news150728581.html Biology Fri, 09 Jan 2009 13:03:01 EST news150728581 Damming of the Colorado River over the last century, alongside introduction of game fish species, has led to an extensive decline in numbers of native fish whilst introduced species have flourished. Scientists have found that physical changes which occur to a river when it is dammed have had an adverse effect only on native fish, due to differences in their life histories. http://www.physorg.com/news134899161.html Space & Earth Thu, 10 Jul 2008 08:59:21 EST news134899161
