Fish were sampled across 28 water bodies encompassing four main habitat types—main rivers (MR), secondary channels (SC), connected lakes (CL), and isolated lakes (IL)—which differ in flow, size, and hydrological connectivity. Main rivers (MR) were wide lotic environments (330–1,100 m), secondary channels (SC) were narrower (28–137 m) and meandered through floodplain islands, connected lakes (CL) were lentic systems permanently linked to channels (3.4–240 ha; 0.7–3.1 m depth), and isolated lakes (IL) were temporarily disconnected from channels (4.1–40.1 ha). Sampling was conducted between 2013 and 2017, covering different hydroclimatic conditions defined by the combination of hydrometric level (high vs. low water) and thermal season (warm vs. cold). Fish were collected using standardized gillnets and beach seine nets (see Borzone Mas et al, 2022 for details). Each individual was identified, measured, and weighed. Twelve ecomorphological measurements were taken on one adult individual of each piscivorous species. (Supplementary table 1 of the article). Morphological traits were rather stable within each species and intraspecific variation was very low in comparison with differences between species (personal observation). These variables were selected following the methodology of Winemiller (1991), Villéger et al. (2011), and Claverie & Wainwright (2014), and were related to mobility, speed, acceleration, and predatory behavior. Fish stomachs were preserved in 10% formalin and examined in the laboratory under a binocular microscope. Fish prey were identified at the species level, while invertebrates were identified at the order level. Preys were classified into the following groups: Characiformes, Siluriformes, Gymnotiformes, Perciformes, other fish orders, invertebrates, fish remains, and plant remains. As large numbers of juveniles of Salminus brasiliensis were collected in the area and this species exhibit strong ontogenetic differences in habitat use and feeding (Rossi et al., 2007), we divided individuals of this species into juvenile (< 1000 g) and adult (> 1000 g) for both food webs and spatial networks.
