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

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.

Fire effects on the cheatgrass seed bank pathogen Pyrenophora semeniperda

The generalist fungal pathogen Pyrenophora semeniperda occurs primarily in cheatgrass (Bromus tectorum) seed banks, where it causes high mortality. We investigated the relationship between this pathogen and its cheatgrass host in the context of fire, asking whether burning would facilitate host escape from the pathogen or increase host vulnerability.
