Examples of critical watersheds.
(a) Watershed showing less than 30% overlap with protected areas. (b) Watersheds showing less than 30% original habitats. (c) Watersheds under direct impact of hydroelectric dam. Dark green lines indicate protected area boundaries, pale green irregular polygons within detected watersheds indicate terrestrial habitat remnants. Dots indicate available records of restricted-range species. 1: Curimata acutirostris Vari & Reis 1995 (Characiformes: Curimatidae); 2: Melanocharacidium auroradiatum Costa & Vicente 1995 (Characiformes: Crenuchidae); 3: Hypostomus paulinus (Ihering 1905) (Siluriformes: Loricariidae); 4: Corydoras flaveolus Ihering 1911 (Siluriformes: Callichthydae); 5: Harttia duriventris Rapp Py-Daniel & Oliveira 2001 (Siluriformes: Loricariidae); Typhlobelus macromycterus Costa & Bockmann 1994 (Siluriformes: Trichomycteridae); 6: Mylesinus paucisquamatus Jégu & Santos 1998 (Characiformes: Characidae).
