Managing Green Infrastructures Trophic Interactions in Anthropogenic and Natural Ecosystems

摘要: The term green infrastructure addresses the spatial structure of anthropogenic, seminatural and natural areas, as well other environmental features which enable society to benefit from ecosystems’ multiple services. Focusing on two infrastructures, anthropogenic wet meadows forest successions, this thesis applies a macroecological approach based comparisons landscapes complex socialecological systems. Firstly, trophic interactions avian predation in under different management regimes southern Sweden were explored (Paper I). This study tested hypothesis that abundance predators is higher rapidly declining vs. relatively stable wader populations. Secondly, large mammals Europe’s boreal biome (paper II). hypotheses reduced numbers carnivores increased herbivores affect recruitment both ecologically economically valuable trees, intensity correlated reduction tree recruitment. results show, firstly, was abundant herbivore populations focal species. There no relationship with index intensity. To conclude, illustrates consequences disturbed tropic infrastructures (anthropogenic forests). governance thus complex, because quantity quality land cover, interactions, need be considered. confirms importance studying altered rather than single landscape or region alone. Macro-ecological studies comparing countries regions contexts, e.g., history, traditions, systems, can support development more holistic views planning infrastructures.
