  2. Granivory and Granivores in Native Grasslands and Agropyron Cristatum Stands in the Northern Great Plains

    Radtke, Troy MarkFaculty of Graduate Studies and Research, University of Regina2012

    Agropyron cristatum (crested wheatgrass) is a management concern in the northern Great Plains because of the low plant biodiversity and high stability in A. cristatum stands. Small consumers have the potential to contribute to A. cristatum invasion and stability through granivory and herbivory. …
