Fig. 9 in Ecology and life history of an Amazon floodplain cichlid: the discus fish Symphysodon (Perciformes: Cichlidae)
Fig. 9. Frequency distribution of the size of Symphysodon haraldi from a single large colony in Uxi Bay, lago Amanã. Column bin-intervals are 3 mm. See Fig. 2 for the timing of sampling in (a) 1998 and (b) 1997. Specimens parasitized with Braga cichlae are excluded. Major modes in the multi-modal distribution of SL are marked with dotted lines and labeled as putative cohort groups (0, 1a, 1b, 2a, 2b, 3, 4) (refer to Fig. 2). Arrows on the x-axis mark the maximum known size of females. X refers to a male specimen marked and released on 20 December 1997 (X1), and recaptured (X2) on 16 November 1998. The overlapping shaded histogram for the 1998 data refers to seven discus captured in adjacent shore scrub. The histograms distributions marked by the beginnings and ends of the dotted triangles for 1a, 1b, and 2 in 1998, and 2a, 2b and 3 in 1997 fit normal distributions (p <0.01, one sample Kolmogorov-Smirnov tests).

Fig. 5 in Ecology and life history of an Amazon floodplain cichlid: the discus fish Symphysodon (Perciformes: Cichlidae)
Fig. 5. Seasonal changes in the proportional composition of food items within stomachs of Symphysodon haraldi from blackwater habitats of the Tefé region. Calculations of mean food item contribution excluded specimens with empty stom- achs. Error bars (displayed above bars) refer to one standard deviation from mean. Algae = periphyton identified as a mass of bright green filamentous structures. FOD = Fine organic detritus. GPM = green plant (macrophytes) matter – apparently mostly small triturated pieces of leaves. Periphyton, FOD and GPM were difficult to separate volumetrically, and are there- fore combined into a single category. GPM represented only a small portion of the volume of this category (perhaps less than 15%). COD = Coarse organic detritus – mainly pieces of wood and bark.
Fig. 11 in Ecology and life history of an Amazon floodplain cichlid: the discus fish Symphysodon (Perciformes: Cichlidae)
Fig. 11. Reproductive status and sex of putative (a) 1+ and (b) 2+ cohort members Symphysodon haraldi from a single large discus colony in Uxi Bay, lago Amanã, 1998. Only specimens that were dissected for sex determination are included. The single 1+ specimen with a stage 4 gonad is illustrated in Fig. 12c.
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).
