TABLE 2 in Stream fish assemblages in the Eastern Amazon: the role of small tetras (Characidae) in alpha diversity and taxonomic structure

TABLE 2 | Abundance and frequency of occurrence (FO, in %) of each fish species sampled in the 99 stream reaches from Parque Nacional da Amazônia (PARNA AM), Parque Nacional do Jamanxim (PARNA JX), Floresta Nacional Saracá-Taquera (FLONA ST), and Reserva Biológica Nascentes da Serra do Cachimbo (REBIO SC). Unidentified juveniles (n = 35) were not included. Classification follows Fricke et al. (2024a). In bold are the two most abundant species as well as all species with more than 50% of occurrence in each area. Vouchers are deposited in the DZSJRP fish collection at the Departamento de Ciências Biológicas, Instituto de Biociências, Letras e Ciências Exatas, Universidade Estadual Paulista “Júlio de Mesquita Filho”, São José do Rio Preto, São Paulo State, Brazil. *Since there may be several lots of the same species, those with the highest number of specimens and/or largest specimens were reported.
