Fig 4. Constrained multidimensional scaling ordination derived from a canonical analysis of principle coordinates of ichthyoplankton samples, plotted according to transect.

Vectors of the correlations of the significant environmental variables of interest (black) along with vectors (grey) of those species (abbreviated, see below) with correlations >0.3 with the first two canonical axes are overlaid onto the ordination. The ordination accounted for 44% of the variation and the first and second squared canonical correlations were 0.65 and 0.36, respectively. Ben_pte = Benthosema pterotum, Emm_nit = Emmelichthys nitidus, Eng_cap = Engraulis capensis, Etr_whi = Etrumeus whiteheadi, Sco_jap = Scomber japonicus, Tra_del = Trachurus delagoa.
