Map of the Upper Paraná River floodplain. The triangles represent the sampling stations of the Paraná River sub-basin, the circles represent the sampling stations of the Baía River sub-basin, and the squares represent the sampling stations of the Ivinhema River sub-basin.

Hydrometric-level (a) and environmental heterogeneity (b) variation between 2000 and 2012 in the Paraná River. The horizontal black dashed line indicates the flood level of the floodplain. Source: ANA - Estação Fluviométrica of Porto São José, PR.

Fig. 4
Beta diversity variation among the guilds. The boxes represent the interquartile ranges, the horizontal lines indicate the medians, the bars indicate the minimum and maximum values, and the closed diamonds represent the mean beta diversity of each guild. LMEF: long-distance migratory and external fertilization; NEFC: non-migratory with external fertilization and parental care; NEFW: non-migratory with external fertilization without parental care; NIF: non-migratory with internal fertilization; DET: detritivorous; HER: herbivorous; INS: insectivorous; INV: invertivorous; ONI: omnivorous; and PIS: piscivorous.

Fig. 5
Relationship between beta diversity (mean distance to centroid), environmental heterogeneity and period of the hydrological cycle. a. Beta diversity of non-migratory fish species with external fertilization and parental care (NEFC); b. beta diversity of non-migratory fish species with internal fertilization (NIF).

Tab. 1
Parameter estimates of generalized least squares linear models relating the beta diversity of each guild to the period and the environmental heterogeneity (EH). SE: standard error of the estimate. LMEF: long-distance migratory and external fertilization; NEFC: non-migratory with external fertilization and parental care; NEFW: non-migratory with external fertilization without parental care; NIF: non-migratory with internal fertilization; DET: detritivorous; HER: herbivorous; INS: insectivorous; INV: invertivorous; ONI: omnivorous; and PIS: piscivorous. EH*Per: interaction term between EH and period. The degrees of freedom for each parameter were 1, and the residual degrees of freedom of each model were 46. *The estimated parameters for the rational quadratic and 1^st order autocorrelation were range and phi, respectively.
