Cleome lutea and Machaeranthera canescens seed transfer zones and distribution on the Colorado Plateau, US
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 Cleome lutea (syn. Peritoma lutea) and Machaeranthera canescens (syn. Dieteria canescens). These species 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. These shapefile data may support successful restoration outcomes if, for example, seed transfer follows...
Effective population size and genetic structure of a Piute ground squirrel (Spermophilus mollis) population
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...
Abstract: Accelerating climate change and other cumulative stressors create an urgent need to understand the influence of environmental variation and landscape features on the connectivity and vulnerability of freshwater species. Here, we introduce a novel modeling framework for aquatic systems that integrates spatially-explicit, individual-based, demographic and genetic (demogenetic) assessments with environmental variables. To show its potential utility, we simulated a hypothetical network of 19 migratory riverine populations (e.g., salmonids) using a riverscape connectivity and demogenetic model (CDFISH). We assessed how stream resistance to movement -- a function of water temperature, fluvial distance, and...
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)...
Allozymic genetic structure and natural habitat fragmentation: Data for five species of Amazonian forest birds
Genetic data from Red-cockaded woodpeckers (Dryobates borealis) used to assess changes in population genetic differentiation and diversity over the past century throughout the southeastern United States
These data include nuclear microsatellite data and mitochondrial DNA sequences (mtDNA) for specimens of Red-cockaded woodpeckers collected from three time points: 1881-1969 (mtDNA only), 1992-1994, and 2010-2014. Additional information regarding individual identifiers, population assignment, regional assignment, and eco-regional assignment are included as are longitude/latitude coordinates for populations.
