Delimiting the boundaries of a species invasion (with no prior info)
in 
Research Briefs | Mar 11, 2010
Research Briefs | Mar 11, 2010 When it comes to successfully controlling invasive species, managers face the critically important step of figuring out the extent of the invasion. Researchers have developed and tested an innovative approach for accomplishing this challenging task...

Creating vegetation barriers to block the spread of invasive species
in Research Briefs | Feb 23, 2010
Research Briefs | Feb 23, 2010 A new study in the journal Biological Invasions shows that land managers may be able to contain highly invasive annual plants by establishing barriers of perennial bunchgrasses to block the spread...

A method for evaluating the potential ecological impact of invasive species
in Research Briefs | Feb 19, 2010
Research Briefs | Feb 19, 2010 Researchers have developed and tested a new method for evaluating the potential ecological impact of the invasive species at a site. Their approach, called the Index of Alien Impact - is innovative for a couple of reasons...

Adverse effects: when stream restoration improves habitat for invasive fish
in Research Briefs | Feb 2, 2010
Research Briefs | Feb 2, 2010 Stream restoration is a commonly used tool for improving the habitat of threatened native fish, particularly salmonids, which have suffered recent declines due to human disturbances. However, as a new study shows, restoration efforts can create their own problems for native fish by unintentionally improving the habitat of invasive species...

Can invasive species enhance the competitve ability of native grasses?
in Research Briefs | Jan 19, 2010
Research Briefs | Jan 19, 2010 Over the past few years, restoration ecologists have made a surprising discovery - the invasion of exotic plants may enhance the competitive ability of native species. Scientists hypothesize that native plants which survive an invasion of exotic species may possess a competitive advantage against the invader which is then reinforced through evolutionary selection...

The ecological benefits of reduced stream flows
in Research Briefs | Jan 14, 2010
Research Briefs | Jan 14, 2010 In the conservation world, conventional wisdom holds that restricting the hydrology of a stream is a bad thing. However, a new article in the journal BioSciences provides a contrarian perspective...
