Field growth comparisons of invasive alien annual and native perennial grasses in monocultures
Throughout the western United States, the invasive annual grass, medusahead (Taeniatherum caputmedusae L. Nevski), is rapidly invading grasslands once dominated by native perennial grasses, such as bluebunch wheatgrass (Pseudoroegneria spicata (Pursh) A). It is also invading grasslands dominated by less undesirable invasive annual grasses, especially cheatgrass (Bromus tectorum L.). Understandi...
متن کاملGenetic variation and local adaptation at a cheatgrass (Bromus tectorum) invasion edge in western Nevada.
Cheatgrass (Bromus tectorum) is an invasive weed in western North America found primarily growing at elevations less than 2200 m. We asked whether cheatgrass is capable of becoming adapted to a marginal habitat, by investigating a population at a high elevation invasion edge. We used a combination of methods, including reciprocal field transplants, controlled environment studies and molecular a...
متن کاملPerceptions of ranchers about medusahead (Taeniatherum caput-medusae (L.) Nevski) management on sagebrush steppe rangelands.
Medusahead (Taeniatherum caput-medusae (L.) Nevski) is an exotic annual grass invading rangelands in the western United States. Medusahead is a serious management concern because it decreases biodiversity, reduces livestock forage production, and degrades the ecological function of rangelands. Despite the obvious importance of ranchers as partners in preventing and managing medusahead in rangel...

وجود پوشش گیاهی پراکنده از ویژگیهای مناطق خشک و نیمهخشک است و در برخی موارد فضای خالی بین این گیاهان با پوستههای زیستی مانند گلسنگها، پوشیده میشود. این پوستهها در یک اکوسیستم مرتعی از جهات گوناگون اهمیت دارند و تأثیرات متعددی بر جوانهزنی و زندهمانی گیاهان آوندی میگذارند. در این تحقیق تأثیرگذاری گلسنگها بهعنوان بخش مهمی از پوستههای زیستی بر جوانهزنی گیاهان علفی غالب مراتع استپی واقع...
متن کاملNative Perennial Grasses Show Evolutionary Response to Bromus tectorum (Cheatgrass) Invasion
Invasive species can change selective pressures on native plants by altering biotic and abiotic conditions in invaded habitats. Although invasions can lead to native species extirpation, they may also induce rapid evolutionary changes in remnant native plants. We investigated whether adult plants of five native perennial grasses exhibited trait shifts consistent with evolution in response to in...
