Fig. 5. Diagram of Canonical Correspondence Analysis (CCA) relating 29 fish species (blue letters), 11 environmental variables (black vectors), and 9 sampling sites each in first-order forest streams (solid green circles) and deforested stream reaches (open red circles) in the Upper Xingu River Basin. Species that had only one (singletons), two (doubletons), or three individuals collected were included in the analysis but are not displayed for improved visualization. Environmental variable marked with * was the strongest predictor of fish assemblage's structure. FBOM = fine benthic organic matter; CBOM = coarse benthic organic matter; Ami = Aequidens michaeli; Amu = Astyanax multidens; Api = Apistogramma sp.; Bra = Brachyglanis sp.; Cro = Crenicichla rosemariae; Etr = Eigenmannia trilineata; Gro = Gymnorhamphichthys rondoni; Gca = Gymnotus cf. carapo; Hac = Hisonotus acuen; Hel = Helogenes marmoratus; Hle = Hypopygus lepturus; Hlo = Hyphessobrycon loweae; Hma = Hoplias malabaricus; Hmu = Hyphessobrycon mutabilis; Hsp = Hyphessobrycon sp.; Hun = Hoplerythrinus unitaeniatus; Mme = Melanorivulus megaroni; Mco = Moenkhausia collettii; Mph = Moenkhausia phaeonota; Pam = Pamphorichthys sp.; Pau = Pyrrhulina australis.
