DOI: 10.1002/ece3.2785
Abstract: Abstract Modification of habitat structure due to invasive plants can alter the risk landscape for wildlife by, for example, changing the quality or availability of refuge habitat. Whether perceived risk corresponds with actual fitness outcomes,… read more here.

The importance of disturbance by fire and other abiotic and biotic factors in driving cheatgrass invasion varies based on invasion stage

DOI: 10.1007/s10530-017-1395-3
Abstract: Disturbances create fluctuations in resource availability that alter abiotic and biotic constraints. Exotic invader response may be due to multiple factors related to disturbance regimes and complex interactions between other small- and large-scale abiotic and… read more here.

DOI: 10.1007/s10530-018-1701-8
Abstract: Invasions by nonnative plants can alter the abundance of native animals, yet we know little about the mechanisms driving these changes. Shifts in vegetation characteristics resulting from nonnative plants can alter availability of food resources,… read more here.

DOI: 10.1007/s10530-021-02633-1
Abstract: Early competition between native and non-native species can greatly influence ecosystem integrity through its effect on species regeneration, which can be further modulated by environmental context. Bromus tectorum (cheatgrass , winter annual grass) has recently… read more here.

DOI: 10.1007/s10980-019-00817-8
Abstract: ContextExotic annual grasses are transforming native arid and semi-arid ecosystems globally by accelerating fire cycles that drive vegetation state changes. Cheatgrass (Bromus tectorum), a particularly widespread and aggressive exotic annual grass, is a key management target… read more here.

DOI: 10.1016/j.ecolind.2017.04.024
Abstract: Abstract The exotic annual grass Bromus tectorum (cheatgrass) dominates vast acreages of rangeland in the western USA, leading to increased fire frequency and ecosystem degradation that is often irreversible. Episodic regeneration failure (“die-off”) has been… read more here.
