We compiled data from fish surveys in six other habitats in the Mamirauá Reserve and used this information to classify rare species in the varzéa lake samples as ‘rare locally’ or ‘rare throughout’. The habitats were open water (n=6098 fish sampled), river/lake banks and margins (n=4689), flooded forest (n=639), floating meadow in river channels (n=5856), forest temporary pools (n=10218), and submerged dead trees (n=425). We used four different methods to decided whether a species is assigned to the ‘rare locally’ category. These are a) present in at least two other habitats; b) present in at least 3 other habitats; c) present in at least 2 other habitats or at least 0.5% relative abundance when present anywhere; d) present in at least 2 other habitats or at least 1% relative abundance when present anywhere.
