(a) Non-metric multidimensional scaling (NMDS) ordination of 172 samples in the Tonle Sap Lake showing the spatial distribution of samples and species in two assemblages: AN and AS. (b) Hierarchical clustering dendrogram of the NMDS scores using the Euclidian similarity matrix and Ward agglomeration method. (c) Boxplot representing the median (––) and 25th and 75th percentiles of fish yields (kg/ha/year) at logarithm scale in both assemblages and (d) Boxplot representing the median (––) and 25th and 75th percentiles of species richness.
