The Glocal Forest

摘要: Spatial ecological patterns reflect the underlying processes that shape structure of species and communities. Mechanisms like intra- inter-specific competition, dispersal host-pathogen interactions can act over a wide range scales. Yet, inference such from is challenging task. Here we call attention to quite unexpected phenomenon in extensively studied tropical forest at Barro-Colorado Island (BCI): spatial deployment (almost) all tree statistically equivalent, once distances are normalized by l0, typical distance between neighboring conspecific trees. Correlation function, cluster statistics nearest-neighbor distribution become species-independent after this rescaling. Global observables (species frequencies) local appear be interrelated. This "glocality" suggests radical interpretation recent experiments show correlation species' abundance negative feedback among conspecifics. For glocal, must govern
