“…While studies of the structuring of natural communities have tended to focus on the role of local environmental conditions, such as disturbances, competition, and abiotic conditions [9], in recent years, spatial processes (geographic distance) have gained growing importance in the analysis of the influence of these different factors [10,11]. Countless studies have attempted to describe or account for the influence of environmental processes and/or spatial factors on the structure of dragonfly communities in various parts of the world [12,13,14,15,16,17,18], although only a relatively small number have focused explicitly on the contributions of both factors in the context of a single system [19,20]. Four notable exceptions, all from Brazil, are Juen and De Marco [4], Brasil [21], and Alves-Martins [22] with studies of adult Odonata in Amazonian streams, and the study of Mendes et al [23], who focused on larvae in streams in the Amazon–Cerrado transition zone.…”
