Fig. 4 in Organization of fish assemblages in blackwater Atlantic Forest streams
Fig. 4. RDA ordination biplot of the first and second RDA axes based on fish biomass (g.m-2) of 31 blackwater mesohabitats. Vector lines in bold type indicate the relationship of the environmental variables to the ordination axis; the line's length is proportional to its relative significance. For species codes, see Tab. 3.

Fig. 5 in Effects of deforestation on headwater stream fish assemblages in the Upper Xingu River Basin, Southeastern Amazonia
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.

Fig. 4. NMDS diagram of the taxonomic structure of fish assemblages in forest (n=9; green solid circles and polygon) and deforested (n=9; red open circles and polygon) stream reaches in the Upper Xingu River Basin. Analysis based on the Bray– Curtis distances of 29 fish species log(x+1)-transformed catch-per-unit-effort. Vectors are species with significant loadings on NMDS axes 1 and 2, and point in the direction of increasing abundance (number of individuals). A. michaeli = Aequidens michaeli; A. multidens = Astyanax multidens; H. marmoratus = Helogenes marmoratus; M. megaroni = Melanorivulus megaroni; M. phaeonota = Moenkhausia phaeonota.

Figure 3. Combined species discovery curve for 226 planthopper canopy fogging samples from Tiputini (one collecting year) including select estimators of diversity. Total observed morphospecies was 432, with 29% represented as singletons. The averaged value of the diversity estimators is 570. Curves for species observed and diversity estimators failed to reach an asymptote.
