The boundary for the Wyoming Basins Ecoregional Assessment (WBEA) was largely determined by the co-occurrence of some of the largest tracts of intact sagebrush (Artemisia spp.) remaining in the western United States with areas of increasing resource extraction. The WBEA area includes two ecoregions in their entirety, Wyoming Basins and Utah-Wyoming Rocky Mountains, and portions of two others (S...

Invasive plants have tremendous potential to enrich native food webs by subsidizing net primary productivity. Here, we explored how a potential food subsidy, seeds produced by the aggressive invader cheatgrass (Bromus tectorum), is utilized by an important guild of native consumers--granivorous small mammals--in the Great Basin Desert, USA. In a series of field experiments we examined 1) how ch...

Many exotic annual grasses are believed to increase wildfire frequency to the detriment of native vegetation by increasing fine fuels and thus, creating a grass-fire cycle. However, information on differences in fuel characteristics between invaded and non-invaded plant communities is lacking, or is basedmainly on speculation and anecdotal evidence. We compared fuel biomass, cover, continuity a...

UNLABELLED Fire, herbivory and their interaction influence plant community dynamics. However, little is known about the influence of prefire herbivory on postfire plant community response, particularly long-term resistance to postfire exotic plant invasion in areas that historically experienced limited large herbivore pressure and infrequent, periodic fires.We investigated the long-term postfir...

Abstract Winter annual grass species such as jointed goatgrass ( Aegilops cylindrica Host), downy brome Bromus tectorum L.), and feral rye Secale cereale L.) negatively affect winter wheat Triticum aestivum yields. To generate a novel in‐crop selective herbicide trait for control, mutagenesis was used to multiple lines resistant the acetyl co‐A carboxylase (ACCase) inhibitor quizalofop p‐ethyl ...
