Fig. 4 in Diet of Hemigrammus marginatus (Characiformes: Characidae) in the Upper Contas River, Diamantina Plateau (Bahia, Brazil)

Fig. 4. Plots of the first two aXes resulting from the Non-Metric Multidimensional Scaling (NMDS) ordination of individuals of Hemigrammus marginatus Ellis, 1911 from drainages of the Upper Contas River, Diamantina Plateau, Brazil, based on the Feeding IndeX (IAi) of the food categories consumed. The triangles correspond to the groups of individuals according to collection sites (Contas and Água Suja rivers), campaigns (dry and rainy seasons), and length classes (classes 1, 2 and 3), and the circles correspond to the food categories. For each graph, the respective fish group was highlighted as a filled triangle and the diameter of the circles is proportional to the IAi values observed for each food category (Mc, microcrustaceans; In, insects; FA, filamentous algae; Dt, detritus).
