Abstract

Better integration of knowledge from ecological,social and economic science is necessary to advance the understanding and modelling of socio-ecological systems.Tomodelecosystemintegrity(EI)and ecosystem services(ES)atthelandscapescale,assessmentmatricesarecommonlyused.Thesematrices assign capacitiestoprovidedifferentservicestodifferentlandcovertypes.Werevisedsuchanexisting matrix andexaminedtheregionalheterogeneityinEIandESprovisioninEuropeandsearchedforspatial gradients intheirprovisiontoelucidatetheirsuitabilityforlarge-scaleEIandESmappinginEurope. Overall, 28sitesbelongingtotheLong-TermEcologicalResearchnetworkinEuropeparticipatedinthis study, coveringalongitudinalgradientfromSpaintoBulgariaandalatitudinalgradientfromItalyto Sweden.
