IAI-Data-CRN_012_Yahdjian_drought: Drought effects on ecosystem functioning in a semiarid grass-shrub steppe South of Argentina

Entry ID: IAIDIS744

[ Update this Record ]

Summary

Abstract: We studied drought effects on ecosystem functioning in a semiarid
grass-shrub steppe South of Argentina. We designed a 2-year rainfall
