Water Use Efficiency by Switchgrass Compared to a Native Grass or a Native Grass Alfalfa Mixture

Grass-herbivore interactions altered by strains of a native endophyte.

Many plants support symbiotic microbes, such as endophytic fungi, that can alter interactions with herbivores. Most endophyte research has focused on agronomically important species, with less known about the ecological roles of native endophytes in native plants. In particular, whether genetic variation among endophyte symbionts affects herbivores of plant hosts remains unresolved for most nat...

Diversity of Nitrogen-Fixing Bacteria Associated with Switchgrass in the Native Tall-Grass

Potential selection in native grass populations by exotic invasion.

Ecological impacts of invasive plant species are well documented, but the genetic response of native species to invasive dominance has been often overlooked. Invasive plants can drastically alter site conditions where they reach dominance, potentially exerting novel selective pressures on persistent native plant populations. Do native plant populations in old exotic invasions show evidence of s...

Promoting Native Vegetation and Diversity in Exotic Annual Grass Infestations

Exotic plant invasions are especially problematic because reestablishment of native perennial vegetation is rarely successful. It may be more appropriate to treat exotic plant infestations that still have some remaining native vegetation. We evaluated this restoration strategy by measuring the effects of spring burning, fall burning, fall applied imazapic, spring burning with fall applied imaza...

evaluation of practical usability in two iranian native grass species

nowadays, establishment and maintenance of turfgrasses due to high water requirements was faced with serious doubts. hence, screening of drought resistance native grasses, and introduces them as turfgrass is not only effective in reduction of water usage but can also preserve plant gene pools of the country. in the present experiment, wheat grass and bromus as two native grasses were compared w...
