Fig. 2. Rarefaction curve (Mao Tau Index) based on the number of samples collected in floating litter banks in four river basins in the Brazilian Amazon (Copacá, Cuieiras, Preto da Eva, and Urubu rivers). (a) All floating litter banks recorded, and (b) disentangling rarefaction models for each river basin.

Fig. 1. Floating litter banks of different dimensions and means of accumulation (i.e., diverse retention mechanisms): (a) floating litter banks retained by branches of riparian vegetation; (b) a large floating litter bank retained in a "ria lake" condition at the confluence of the Aliança Stream with the Branco River; (c) a small floating litter bank close to the margin of a 4th-order stream in the Urubu River basin; and (d) a large floating litter bank almost completely out of the water in a stream in the Urubu River basin during the dry season.

Fig. 3. The fish fauna associated with kinon banks is dominated by species of characins (Characiformes), catfishes (Siluriformes) and electric knife fishes (Gymnotiformes). Some of the more common and abundant species in our samples were the following: (a) Elachocharax pulcher, Crenuchidae; (b) Hypopygus lepturus, Hypopomidae; (c) Batrochoglanis raninus, Pseudopimelodidae; and (d) Brachyglanis microphthalmus, Heptapteridae.
