IAI-Data-CRN_012_Covalschi_hs: Regional and local controls of vegetation spatial-heterogeneity in the Patagonian steppe

The objective of this study was to determine regional and local controls of vegetation spatial-heterogeneity in the Patagonian steppe. We considered two possible factors, rainfall and ovine herbivory. We analyzed vegetation cover along gradients of herbivory and rainfall. Data were obtained for project CRN12 (The Role of Biodiversity and Climate in the Functioning of Ecosystems: A Comparative Study or Grasslands, Savannas, and Forests), wich has Dr. Osvaldo E. Sala as PI.
