European Shrimp Win Predatory Battles With An American Invader
2013-10-11 12:24:02

Pensoft Publishers A shrimp from America has been invading Europe's rivers and lakes for several decades, but something seems to be preventing this colonist from becoming numerous and problematic, like so many other invaders - such as the Californian grey squirrel and American crayfish. Could the resident European shrimp have something to do with this? Jaimie Dick and his colleagues mapped the occurrence of the interloper and found it only existed where native shrimp were absent or...

Human Life Span Linked To Endangered Species

April Flowers for redOrbit.com - Your Universe Online A new study from the University of California, Davis reveals that as human life expectancy increases, so does the number of endangered and invasive bird and mammal species. The research team examined a combination of 15 social and ecological variables, ranging from tourism and per capita gross domestic product to water stress and political stability, then analyzed the correlations with invasive and endangered birds and mammals, which are...

Brett Smith for redOrbit.com - Your Universe Online A new study from researchers at Ohio State University tells the story of an invasion and domination that took place around 450 million years ago in North America. During the Ordovician period, a dramatic ecological shift occurred near what are now the Appalachian Mountains, as represented in the fossil record. In the study, which was published recently in the journal PLOS ONE, Ohio State paleontologists provide evidence of significant...

Invasive Ladybugs Use Biological Warfare On Native Species

Brett Smith for redOrbit.com - Your Universe Online German researchers have uncovered another cautionary tale about the importation of a species that quickly becomes an invasive threat. Introduced to Europe and North America for the purpose of controlling pesky greenhouse aphids, the Asian lady beetle escaped into the ecosystem and quickly dominated the local ladybug population. According to a new report in the journal Science, the aggressive ladybug´s dominance is being assisted...

Globalization, with its ever increasing demand for cargo transport, has inadvertently opened the flood gates for a new, silent invasion. New research has mapped the most detailed forecast to date for importing potentially harmful invasive species with the ballast water of cargo ships. Scientists from the Universities of Bristol, UK, and Oldenburg, Germany, have examined ship traffic data and biological records to assess the risk of future invasions. Their research is published in the...

Marsh Crabs Show Ecological Benefits Of Invasive Species
2013-04-04 10:17:30

Alan McStravick for redOrbit.com - Your Universe Online The marsh systems around Cape Cod have been eroding at a rapid rate in the past few decades. As redOrbit reported in January, researchers from Brown University were able to find a cause and effect relationship between human interaction with the ecosystem and the rapid increase in the native purple crab population. As their research detailed, human manipulation of the region via recreational overfishing and the creation of drainage...

New initiatives have transformed how we gather and consolidate information about harmful invaders. Scientists with the Weed Science Society of America (WSSA) say it is important to use that information to take effective action before an infestation spreads. LAWRENCE, Kansas (PRWEB) March 26, 2013 Over the past decade, dozens of “early detection, rapid response” initiatives have been launched by states to keep invasive species from devastating natural habitats and damaging our...

American bullfrogs are native to eastern North America but have been transported by people to many other parts of the globe, and other parts of North America, where they have readily established populations and become an invasive alien menace to native ecosystems. In the largest study of its kind to date, the stomach contents of over 5,000 invasive alien American bullfrogs from 60 lakes and ponds on southern Vancouver Island were examined to identify the native and exotic animals that they...

Scientists Raise Concerns Over Tsunami Debris Carrying Invasive Species
2013-03-10 08:25:22

redOrbit Staff & Wire Reports - Your Universe Online Two years after the earthquake and tsunami that devastated Japan, researchers in the US and Canada are concerned about the possible damage that could be caused by invasive species that have found their way to North America on debris resulting from the 2011 disaster. According to UPI, experts in the northwest US and Canada are having difficulty determining whether or not marine life washing ashore on the debris will be a threat to...

The Pacific Oyster (Crassostrea gigas), is the native oyster of the Pacific coast of Korea, Japan and China. It has been introduced to North America, especially in Puget Sound, Washington, and to the Australian states of Tasmania and South Australia. It is an important commercial harvest in all of these places, as well as New Zealand where the Pacific oyster has replaced the native rock oyster, Crassostrea glomerata, as the main commercial species. The Pacific oyster is an invasive species...
