Abstract excerpt
UNLABELLED: PREMISE OF THE STUDY: Phenotypes of two Andropogon gerardii subspecies, big bluestem and sand bluestem, vary throughout the prairie ecosystem of North America. This study sought to determine the role of genetics and environment in driving adaptive variation of leaf structure in big bluestem and sand bluestem. • METHODS: Four populations of big bluestem and one population of sand bluestem were planted...
