FIGURE 2. Map showing the geographic location of the study area. The inset shows the easternmost part of Brazil and four important cities as reference points: 1.) Belém, State of Pará; 2.) Salvador, State of Bahia; 3.) Rio de Janeiro, State of Rio de Janeiro; 4.) Brasília, Distrito Federal (Federal District). The darker, diagonal area surrounded by lighter areas represents the shrublands and dry forests of the Caatingas, bordered on the west and east by forest and degraded forest and on the south by the Cerrado grasslands. The area delimited by the smallest darker rectangle is magnified to show the dune fields on the west bank of the São Francisco River (S.F.R.) The dune field is bordered on the west by the Serra do Estreito (S.E.). Its northern limit is represented by the small triangles. The Icatu River (I.R., the only perennial river crossing the dunes), the Grande River (G.R.), and the Lagoa de Itaparica (L.I.), as well as the urban centers of the municipalities of Barra (BAR.) and Xique-Xique (X.X.) are shown for geographic reference. The fieldwork was performed in the dunes with sharp morphology (lighter strip along the SFR; black arrow) near the village of Ibiraba (IB.). The coordinates of the central point in this image are 10°30'S-42°45'W.
