Figure 3From: Evolution of the nuclear ribosomal DNA intergenic spacer in four species of the Daphnia pulex complexUnrooted Neighbour-joining dendrogram of complete IGS sequences from representatives of four species in the Daphnia pulex complex. The inset shows a phylogeny of these species based on the mitochondrial ND5 gene [17]. Dpc = D. pulicaria, DpxE = European D. pulex, DpxNA = North American D. pulex, Dten = D. tenebrosa.Back to article page
