Scientists from Oregon State University and Portland State University develop the transcriptome and other genetic resources of an invasive plant, Brachypodium sylvaticum, for extensive research on plant adaptation In order to build and maintain cells, DNA is copied into ribonucleic acid (RNA) molecules, also called transcripts. Transcripts are often like a recipe for making proteins, and a collection of all the transcripts in a cell is called a transcriptome. Pankaj Jaiswal, Assistant...

Plant Biodiversity Protects Ecosystems From Human Perils
2013-02-07 08:59:14

April Flowers for redOrbit.com - Your Universe Online A new study led by integrative biologists at the University of Guelph warns of the perils inherent in an ecosystem breakdown. The findings of the study, which appeared as the cover story in today´s issue of the journal Nature, suggest that resource managers and farmers should not rely on single crop monocultures, no matter how stable they may appear to be. The team suggests instead that farmers should cultivate the growth of more...

Biocontrol Research Discovers New Cryptic Species On Brazilian Peppertree In Florida

Pensoft Publishers Dr Michael Pogue, a Research Entomologist in the ARS Systematic Entomology Laboratory, at the Smithsonian Institution, Washington, DC, was sent a series of moth specimens from Bahia, Brazil, for identification. The insects were under consideration as a possible biocontrol agent for the invasive Brazilian peppertree in Florida. 'The species was initially identified as a common species, but when comparisons were made, it became evident that there were multiple species...

Effect Of Invasive Plants On Species Richness Depends On Scale

Washington University in St. Louis In Missouri forests, dense thickets of invasive honeysuckle decrease the light available to other plants, hog the attention of pollinators, and offer nutrient-stingy berries to migrating birds. They even release toxins to make it less likely native plants will germinate near them. Why, then, are recent popular science articles recommending a recalibration of the traditional no-tolerance attitude toward non-native species, suggesting that we´ve...

Ecologists at the University of Toronto and the Swiss Federal Institute of Technology Zurich (ETH Zurich) have found that, given time, invading exotic plants will likely eliminate native plants growing in the wild despite recent reports to the contrary. A study published in Proceedings of the National Academy of Sciences (PNAS) reports that recent statements that invasive plants are not problematic are often based on incomplete information, with insufficient time having passed to observe...

Invasive Grass May Be Contributing To Extreme Wildfires
2012-12-06 13:33:34

April Flowers for redOrbit.com - Your Universe Online An international team of scientists comprised of members from Penn State, UMass Amherst, UC Santa Barbara (UCSB) and University College London has revealed that an invasive grass species may be one reason that fires are bigger and more frequent in certain regions of the western U.S. Using satellite imagery, the team identified cheatgrass — a plant species accidentally introduced by western settlers during the 1800s...

Invasive Species Abound In The River Thames
2012-10-10 05:02:07

Alan McStravick for redOrbit.com - Your Universe Online A new study out of the U.K. points out what many ecosystems of the world have already known. In this new study, scientists from the Queen Mary, University of London, claim that almost 100 non-native freshwater species have successfully invaded the River Thames, making it one of the world´s most highly invaded freshwater systems. Published in the journal Biological Invasions over the weekend, scientists suggest that previous...

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...
