The fluctuating resource hypothesis explains invasibility, but not exotic advantage following disturbance

Publications Posted on: September 26, 2018
Invasibility is a key indicator of community susceptibility to changes in structure and function. The fluctuating resource hypothesis (FRH) postulates that invasibility is an emergent community property, a manifestation of multiple processes that cannot be reliably predicted by individual community attributes like diversity or productivity.

Effects of resource availability and propagule supply on native species recruitment in sagebrush ecosystems invaded by Bormus tectorum

Publications Posted on: September 13, 2010
Resource availability and propagule supply are major factors influencing establishment and persistence of both native and invasive species. Increased soil nitrogen (N) availability and high propagule inputs contribute to the ability of annual invasive grasses to dominate disturbed ecosystems. Nitrogen reduction through carbon (C) additions can potentially immobilize soil N and reduce the competitiveness of annual invasive grasses.

What makes Great Basin sagebrush ecosystems invasible by Bromus tectorum?

Publications Posted on: July 06, 2007
Ecosystem susceptibility to invasion by nonnative species is poorly understood, but evidence is increasing that spatial and temporal variability in resources has large-scale effects.
