TABLE 1 in Functional diversity: a review on freshwater fish research

TABLE 1 | Extracted data from the articles, description of the classification and application for each topic analyzed.
Extracted dataClassificationApplicationa) Year of publication1945–2021Used to determine the temporal trend of publications.b) Biogeographic realmPalearctic, Nearctic, Neotropical, Indomalayan, Australian, Afrotropical, and Global (when the study assessed more than one region).Used to identify the distribution of research effort among biogeographic realms.c) Freshwater environmentRiver, Stream, Lake, Reservoir, Floodplain, and several (when the study assessed more than one environment). 1) Biological invasion; 2) Climate change; 3) Conservation; 4) Environmental factors; 5) Environmental filtering; 6) Flood pulse; 7) FunctionalUsed to verify the type of freshwater ecosystem most assessed.d) General backgroundstructure; 8) Habitat heterogeneity; 9) Impoundments; 10) Land use; 11) Lateral connectivity; 12) Methodological; 13) Multiple stressors; 14) Taxonomic and functional patternsClassification based on the main objectives of the studies.e) Functional traitEcological traits; morphological traitsClassification based on the type of trait measure. Used to identify the traits most applied to assess functional diversity.f) Functional categoryFeeding; Habitat use; Life History; Locomotion; and Physiology (Classified according to Villéger et al., 2017).Identify which functional category with the greatest number of traits evaluated.g) Functional diversity indexAll indices found in the reviewed studies.Used to identify the main index applied to quantify the functional diversity of fish.
