Genetically informed seed transfer zones for Pleuraphis jamesii, Sphaeralcea parvifolia, and Sporobolus cryptandrus across the Colorado Plateau and adjacent regions
These data were compiled to provide seed transfer and native plant materials development guidance to managers and practitioners across the Colorado Plateau and in adjacent regions. This data release contains empirical seed transfer zones derived from molecular genetic data for Pleuraphis jamesii (syn. Hilaria jamesii), Sphaeralcea parvifolia, and Sporobolus cryptandrus. Pleuraphis jamesii and Sphaeralcea parvifolia show distinct population structure (i.e., genetic differentiation) across their ranges ; as such, seed transfer zones reflect both patterns of genetic differentiation and information on each species' unique adaptations to climatic gradients. Sporobolus cryptandrus did not display discrete population structure...
A general suite of fungal endophytes dominate the roots of two dominant grasses in a semiarid grassland
Although research has shown that root associated fungi (RAF) are necessary for plant success in harsh environments, few studies have examined RAF community variability between different plant species coexisting in arid habitats. We compared the diversity and composition of the fungal communities colonizing dominant and important forage grasses, Bouteloua gracilis and Sporobolus cryptandrus, inhabiting the Sevilleta National Wildlife Refuge, a semiarid grassland in New Mexico. A third sympatric plant, Yucca glauca (Agavaceae), also was analyzed. ITS rDNA from roots, collected and amplified in 2007, yielded 447 fungal sequences. Sequences obtained from all three species suggest that grasses share a core group of RAF...
As restoration needs for natural landscapes grow due to higher frequency and/or intensity disturbances, pressure from invasive species, and impacts resulting from changing climates, considerable time and resources are being invested to guide the development and deployment of native plant materials (NPMs). Across lower elevations of the Colorado Plateau, a region composed primarily of public land where arid conditions make restoration especially challenging, NPM coordination has been spearheaded the Bureau of Land Management’s Colorado Plateau Native Plant Program (CPNPP) since 2009. To help CPNPP achieve its vision of healthy and resilient native plant communities, the Southwest Biological Science Center (SBSC)...
