Figure 1From: Unsuspected diversity of Niphargus amphipods in the chemoautotrophic cave ecosystem of Frasassi, central ItalyUnrooted maximum-likelihood tree of 12S mitochondrial sequences. This tree was generated with PhyML under the model TIM3+G (127 parameters) selected by jModelTest. Individual sample names are not shown for the sake of clarity, and Neighbor-joining (NJ)/Maximum Parsimony (MP)/Maximum Likelihood (ML) bootstrap values (1000 replicates) are displayed next to each node.Back to article page
