Effect of altitude on the genetic structure of an Alpine grass, Poa hiemata.

abstract：BACKGROUND AND AIMS:Recent biodiversity research has focused on ecosystem processes, but less is known about responses of populations of individual plant species to changing community diversity and implications of genetic variation within species. To address these issues, effects of plant community diversity on the per...
