FIGURE 4 in Fish functional trophic groups in headwater karst streams from the Upper Paraguay River basin

FIGURE 4 | Compilation of number of families on each Functional Trophic Group among different biomes in Brazil. Bar colors represent the shared FTGs among biomes considering Sazima (1986), Sabino, Zuanon (1998), Casatti et al. (2001), Brejão et al. (2013), Freitas et al. (2021), and this work. Blue bar: FTGs registered in Pantanal+Amazon+Atlantic Forest; Red bar: FTGs registered in Pantanal+Amazon; Green bar: FTG registered only in Amazon. Silhouettes represent the families with more records on each FTG.

Data underlying submission "Tracing stream flow in confluent rivers – a journey from chaos to order"

These data underly the analysis presented in the manuscript "Tracing stream flow in confluent rivers – a journey from chaos to order" by Erwin Zehe, Samuel Schroers and Hubert Savenije. The data used for this analysis are available were taken from the globally available the HydroSHEDS data base at https://www.hydrosheds.org created by Lehner et al. (2008). The extracted data for analyzing the 18 of the largest Rivers are stored as csv files sorted by river names. The metadata are provided in "HydroSHEDS_TechDoc_v1_4.pdf" and "BasinATLAS_Catalog_v10.pdf". The matal codes for data analysis and simulations were tested and should be self-explaining.  Lehner, B., Verdin, K. & Jarvis, A. New Global Hydrography Derived From Spaceborne Elevation Data.
