A genecological approach was used to explore genetic variation for survival in Artemisia tridentata (big sagebrush). Artemisia tridentata is a widespread and foundational shrub species in western North America. This species has become extremely fragmented, to the detriment of dependent wildlife, and efforts to restore it are now a land manage-ment priority. Common- garden experiments were established at three sites with seed-lings from 55 source- populations. Populations included each of the three predominant subspecies, and cytotype variations. Survival was monitored for 5 years to assess dif-ferences in survival between gardens and populations. We found evidence of adap-tive genetic variation for survival. Survival...

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...

Ecological genetics,
The use of molecular techniques for the assessment of familial relationships among social species of mammals has become relatively commonplace. However, some species represent poor candidates for such studies due to naturally low levels of genetic diversity, leading to unacceptably large standard errors associated with estimates of relatedness. Here, we report on a preliminary study of genetic diversity within two populations of a social species of ground squirrel, Gunnison's prairie dog (Cynomys gunnisoni) using DNA fingerprinting. We observed low levels of diversity in the form of large mean coefficients of genetic similarity among individuals occupying the same population. Overall similarity, determined from...

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...
