bromus tectorum การใช้

• The frequency of wildfire is increasing as the habitat is invaded by cheatgrass ( " Bromus tectorum " ).
• Invasive species of plants have been introduced to the habitat, including " Bromus tectorum ", a competitive grass.
• Cheatgrass ( " Bromus tectorum " ) is also an important introduced plant species that increases fire risk in this ecosystem.
• Burrow densities were highly variable in mixed exotic annual communities, and negatively correlated with cheatgrass ( " Bromus tectorum " ).
• An example of an invasive species in the area of the Beaver Creek Fire is cheat grass, " Bromus tectorum ".
• All sites were dominated by Russian-olive with cheatgrass ( " Bromus tectorum " ) comprising a substantial portion of the understory.
• Changes in fire regimens are another form of facilitation . " Bromus tectorum ", originally from Eurasia, is highly fire-adapted.
• Threats to the species include roads, off-road vehicles, introduced species, particularly " Bromus tectorum ", and fire suppression.
• Therefore, the presence of biological soil crusts may slow the establishment of invasive plant species such as cheatgrass ( " Bromus tectorum " ).
• Cheatgrass ( " Bromus tectorum " ) is a particularly troublesome weed across much of western North America ( from southern British Columbia to California .)
• Invasive species, such as " Lygodium microphyllum " and " Bromus tectorum ", can grow rapidly in areas that were damaged by fires.
• Threats to the species include road development, which cuts through the habitat and also facilitates the spread of introduced species of plants such as " Bromus tectorum ".
• In Kashmir, the seeds of a species of " Eragrostis " was particularly dominant in their diet while those in the US favoured " Bromus tectorum ".
• Other threats include highway maintenance, introduced species of plants such as cheat grass ( " Bromus tectorum " ), herbicides, rock climbing, motor vehicle emissions, and global warming.
• Fire also increases the spread of introduced species of plants such as cheatgrass ( " Bromus tectorum " ), and the cover of cheatgrass then increases the likelihood and severity of fire.
• Habitat disturbance can have long-lasting effects on the environment . " Bromus tectorum " is a vigorous grass from Europe which has been introduced to the United States where it has become invasive.
• Also, the landscape has been taken over by introduced species of plants, such as " Bromus tectorum ", cheatgrass, a change which has been intensified by cattle grazing in the area.
• The fungus has been collected in California, Idaho, Montana, Oregon and Washington . " M . snyderi ", identified as phylogenetic species " Mel "-12, has been shown to colonize the non-native species " Bromus tectorum " ( cheatgrass ) as an endophyte.
• "Morchella sextelata ", identified as phylogenetic species " Mel-6 ", has been shown to colonize the non-native species " Bromus tectorum " ( cheatgrass ) as an endophyte, increasing the overall growth of the grass, as well as the abundance of seeds and their tolerance to extreme heat ( ).
• In southeastern Idaho, big sagebrush / crested wheatgrass ( " Agropyron cristatum " ) range, most Ord's kangaroo rat captures occurred on disturbed sites or areas of sparse cover : Russian thistle ( " Salsola kali " ), cheatgrass ( " Bromus tectorum " ), and green rabbitbrush ( " Chrysothamnus viscidiflorus " ), followed by disturbed areas seeded to crested wheatgrass, then undisturbed big sagebrush.
