Positive effects of native shrubs on Bromus tectorum demography

Ecology, 2010
There is increasing recognition that overall interactions among plant species are often the net result of both positive and negative effects. However, the positive influence of other plants has rarely been examined using detailed demographic methods, which are useful for partitioning net effects at the population level into positive and/or negative ...

High Phenotypic and Molecular Variation in Downy Brome (Bromus tectorum)

Invasive Plant Science and Management, 2008
Abstract The invasive grass Bromus tectorum (cheatgrass, downy brome) has extensive ecological breadth in its introduced range, and is increasing in abundance at high elevations. As a predominantly selfing species with high potential population growth rates, it is a likely candidate for having general-purpose genotypes that facilitate its invasion into

Ecological genetics of Bromus tectorum

Oecologia, 1991
By incorporating demographic analyses of fitness components (e.g., survival and reproduction) within a reciprocal sowing design, we tested for 3 consecutive years whether local adaptation has occurred in the alien grass Bromus tectorum (cheatgrass) within 7 habitats along an environmental gradient from arid steppe to subalpine forest in the ...

Biotic filtering of endophytic fungal communities in Bromus tectorum

Oecologia, 2019
The assembly of horizontally transmitted endophytic fungi within plant tissues may be affected by "biotic filtering". In other words, only particular endophytic fungal taxa from the available inoculum pool may be able to colonize a given plant species.

Bromus tectorum cover mapping and fire risk

International Journal of Wildland Fire, 2006
Fire risk in western North America has increased with increasing cover of Bromus tectorum, an invasive alien annual grass. The relationship between B. tectorum cover and fire risk was determined in a historically burned Artemisia tridentata-Poa secunda shrub–steppe community where B. tectorum cover ranged from 5 to 75%.

The Demography of Bromus Tectorum: Variation in Time and Space

The Journal of Ecology, 1983
(1) Amplitude in the variation of recruitment, survivorship and fecundity was examined for the introduced annual grass Bromus tectorum in three habitat types in eastern Washington (U.S.A.) for three consecutive generations. A total of 18 143 individuals in populations varying from 364 to 5322 members per site were mapped repeatedly from emergence to ...
