These data were collected to evaluate if arrowweed (Pluchea sericea) individuals and genotypes collected from across a 5.3 degree Celsius temperature gradient and grown in a common greenhouse environment had different physiological and morphological responses to inundation. The objectives of the study were to assess if 1) individuals from climatically different provenances differ in their morphological and physiological phenotypes, 2) individuals from climatically different provenances differ in their response to inundation, and 3) phenotypes and inundation responses are partially controlled by genotype. These data represent measurements made on 248 plants that were grown in a greenhouse and, also in a greenhouse...

These data represent nuclear microsatellite data collected from four riparian plant species that occur in and around Grand Canyon National Park: Populus fremontii (POFR), Salix gooddingii (SAGO), Salix exigua (SAEX), and Prosopis glandulosa (PRGL). These data were collected for population genetic analysis to help inform native plant material development in Grand Canyon National Park. Leaf samples were collected at sites spanning 470 km of the Colorado River between Glen Canyon Dam and Lake Mead and in tributaries. Known revegetation areas were not sampled. We aimed to collect leaf tissue from at least 15 individuals at each sample site. If there were fewer than 15 individuals per species at a site, leaf tissue was...
