ReefSYN | Standardized datasets of Brazilian reef diversity in space and time - Dataset I: Fish communities from the Brazilian province

OBIS Brazil MeasurementOrFact Open in mapper Explore occurrences

This dataset is part of a broader compilation named 'Standardized datasets of Brazilian reef diversity in space and time' created from a research network of reef scientists within several projects and collaborations and finally gathered and published by the ReefSYN group. This dataset, an updated, filtered and curated version of the one used by Morais et al. (2017), includes fish counts and size estimates in 4,570 transects distributed over 137 localities in 20 different locations, spanning from 0° to 27°S (including oceanic islands). This dataset is the foundation of a large network of reef scientists in Brazil, which started as the project SISBIOTAMar and derived into the PELD ILOC and ReefSYN networks.
