Description of the data and file structure

We collected data from 98 first to second-order streams in the Brazilian Amazon (9W 12' 36", 51S 41' 46"). The biological data were collected by the fixed-sweeping method, using an entomological net in a 150-m stream stretch, from 10 AM to 02 PM, performed by one researcher. The abiotic data were measured by using a multiparameter probe and visual protocols, addressing limnological and physical structuring variables. The protocol is described in the main manuscript.
