“…Also, the ubiquitous usage of Parker's classification in academic studies in the Neotropics may be an additional reason for the continuing usage of this metric in EAs. Since its publication, this parameter has been used in many studies, as an untreated dependent variable, associated with other parameters to test the effects of fragmentation and landscape features in bird assemblages (e.g., Petit and Petit, 2003;Uezu et al, 2005;Barlow et al, 2006;Edwards 2006, Feeley et al, 2007;Hansbauer et al, 2008b;Lees and Peres, 2008;Martensen et al, 2008Martensen et al, , 2012Ferraz et al, 2012;Banks-Leite et al, 2013), as a parameter to support discussions about human disturbance effects on birds and habitat conditions (e.g., Woltmann, 2003;Oostra et al, 2008;Giacomo and Casenave, 2010;Lobo-Araújo et al, 2013) and to characterize the bird communities at a given site (e.g., Matlock Jr et al, 2002; Tejeda-Cruz Franz et al, 2010;Arendt et al, 2012;Lyra-Neves et al, 2012). However, being the most used ecological indicator in the scientific literature does not mean that it is suitable for all types of environmental assessment (Dale and Beyeler, 2001;Carignan and Villard, 2002).…”
