Secondary invasion re-redefined: The distinction between invader-facilitated and invader-contingent invasions as subclasses of secondary invasion

Publications Posted on: September 26, 2018
In their recent article in Ecology and Evolution, O’Loughlin and Green (2017) set out to (1) redefine the term secondary invasion as the condition "when invader success is contingent on other invaders altering the properties of recipient ecosystems" and (2) propose a framework for accounting for this phenomenon in invasion ecology. We applaud the second objective.

Genetic variation and local adaptation at a cheatgrass (Bromus tectorum) invasion edge in western Nevada

Publications Posted on: October 03, 2011
Cheatgrass (Bromus tectorum) is an invasive weed in western North America found primarily growing at elevations less than 2200 m. We asked whether cheatgrass is capable of becoming adapted to a marginal habitat, by investigating a population at a high elevation invasion edge. We used a combination of methods, including reciprocal field transplants, controlled environment studies and molecular analysis.

Effects of picloram application on community dominants vary with initial levels of spotted knapweed (Centaurea stoebe) invasion

Publications Posted on: December 06, 2010
Broadleaf herbicides are commonly used to suppress exotic weeds with the intent of releasing native species from negative impacts of invasion. However, weed control measures can also have unintended consequences that should be considered along with intended effects.
