Understanding interactions between ecosystem services (ES) is a high priority in ES research. Two types of interaction are commonly defined: (1) tradeoffs, in which one service increases while another one decreases in time or space; (2) synergies, in which both services either increase or decrease. Most studies on ES use statistical analysis and descriptive methods to assess ES spatial or temporal correlation. Recently, a new framework for ES interactions based on ecological-economic production possibilities frontier (EEPPF) has been developed, which relies on the production theory branch of microeconomics. Applied to natural capital, this framework consider s different levels of ES produced across a broad range of management actions and landscape configurations and describes graphically the nature and intensity of ES interactions by determining the production frontier (i.e. the set of Pareto-optimal values for pairs of ES). This study aims to estimate empirically EEPPF between multiple ES in the Volcanica Central-Talamanca Biological Corridor, Costa Rica, and to discuss the EEPPF framework complementarity with statistical approaches. InVEST software was used to model ES production for carbon storage (C), water yield, sediment retention, nitrogen retention (n) and phosphorus retention (p). Agricultural production (pa) was represented by its economic value. Spatial concordance and temporal covariation between ES were analyzed using statistical correlations (modified t-test) for four observed land-uses (LU) over time. EEPPF curves were constructed using a set of 32 contrasting LU scenarios generated, considering slope and altitude constraints for some LU and assuming different LU proportions and distributions (either random or clustered). EEPPF analysis showed tradeoffs between C and other ES, and between pa and nutrient retention (nand p). The shape of EEPPF curves illustrated the intensity of tradeoffs. The nature and intensity of interactions between C and other ES
