摘要：Several studies confirm that biodiversity loss endangers ecosystem services (ES) supplyand human well-being. A better understanding of biodiversity–ES relationships andeffects of biodiversity loss on ES supply is needed. The objective was to determinerelationships between potential biodiversity and three ES in Patagonia where cattleranching under silvopastoral use occurs. We used grids of potential biodiversity (plantspecies richness) and three ES, provisioning (cattle stocking rate), regulating (CO2 sequestration) and cultural (geo-tagged digital-images). Potential biodiversity was negativelyrelated to provisioning, but no significant relations were detected with regulating andcultural. These relations showed regional differences related to forest landscape distribution. High values of regulating were found in southern areas being coincident with highpotential biodiversity. Opposite trends (negative relationship with biodiversity) wasobserved for provisioning in eastern and western regions where provisioning decreasefrom N-S. Results suggest that provisioning do not overlap spatially with the higher valuesof potential biodiversity maps, which is an advantage for land use planning when conservation and management requirements must be combined. Our results are the firstcontribution for Patagonia to underpin scientific and institutional efforts to connectbiodiversity conservation with ES maintenance. However, further studies must beaddressed including more ES and regions.
