Fig. 1. NASDA JERS-1 in Ecology and life history of an Amazon floodplain cichlid: the discus fish Symphysodon (Perciformes: Cichlidae)

Fig. 1. NASDA JERS-1 radar image of the Tefé region, Brazil: (a) high water (May 1995); (b) low water (September 1995). Flooded forests appear white, illustrating the maximum extent of the seasonal flooding. The area between the dotted lines is whitewater floodplain. R. Solimões is the local name for the Amazon River. Discus occur in the following habitats: 1, blackwater flooded forest (igapó), 2, blackwater lakes, 3, whitewater flooded forest, 4, whitewater floodplain lakes. Study are marked A (Uxi Bay) and B (lago Urini). Inset (c) shows Uxi Bay from Landsat TM-5 image, 1998. Here, the white dot represents the locality of a large discus colony and the line X-Y refer to the cross-sectional schematic (d). In (d) the dotted horizontal line represents the water level at the beginning of 1998 samples. The 4 m water-level (see also Fig. 2) marks the lower levels of shore scrub growing on beaches and sand bars. Shore scrub is dominated by Coccoloba ovata Benth. and Symmeria paniculata Benth. (Polygonaceae).
