Climate change and biodiversity conservation in Great Plains agroecosystems

Global change and habitat fragmentation are critical issues in our society. While considerable progress has been made in these issues worldwide, the unique features of the agroecosystems in the Great Plains have not been given enough attention. In this region, croplands occupy the majority of the landscape, forming the mosaics with linear riparian zones and shelterbelts. These three elements play different roles in the maintenance of biodiversity, and their continued effectiveness under a changing climate is critical to maintaining a healthy and productive agricultural ecosystem. This article evaluates current research and discusses future directions. The goal is to provide a scientific base for future conservation biology and wildlife management.
