High Land-Use Intensity Diminishes Stability of Forage Provision of Mountain Pastures under Future Climate Variability

摘要: Semi-natural, agriculturally used grasslands provide important ecologic and economic services, such as feed supply. In mountain regions, pastures are the dominant agricultural system face more severe climate change impacts than lowlands. Climate threatens ecosystem functions, aboveground net primary production [ANPP] its nutrient content. It is necessary to understand of land-management on ecosystems develop management practices sustainably maintain provision services under future climatic conditions. We studied effect different land-use intensities plant-soil communities by downslope translocation mesocosms along an elevation gradient in 2016, subsequent application two types (extensive vs. intensive). Communities’ response ANPP leaf carbon (C), nitrogen (N), phosphorus (P) content was quantified over years after translocation. increased with warming 2017 both intensities, but this amplified intensive management. 2018, intensively managed decreased, comparison 2017, from 35% 42%, while extensively maintained their levels. The changes coupled exceptionally dry year up 100 days drought C:N higher those ones, further potentially indicating shifts resource allocation strategies that may explain stability. Our results revealed a low resistance communities’ especially ability alter likely enables constant level extensive management, lost Thus, events leave non-sustainable farming practice, ultimately threaten montane pastures.
