Scale analysis of carabids richness (Coleoptera: Carabidae) in southern South America

The southern South America presents a complex history of geomorphological and climatic events, which have modulated and fragmented the southwestern part of the Andes mostly. Given the complexity of the southern landscape, the analysis of the hierarchical components alpha-α, beta-β...

description	The southern South America presents a complex history of geomorphological and climatic events, which have modulated and fragmented the southwestern part of the Andes mostly. Given the complexity of the southern landscape, the analysis of the hierarchical components alpha-α, beta-β and gamma-γ on carabid diversity allows exploring the responses of species to spatial changes patterns according to the scales of the landscape. In order to understand how spatial scales influence the carabid diversity in southern South America, we used an approach at multiple spatial scales of multiplicative diversity partitioning. We included four spatial scales in our analysis: among 0.25° quadrats, 0.5° quadrats, provinces and biogeographic sub-regions.
