FIGURE 1 in The Naticidae (Mollusca: Gastropoda) of Giglio Island (Tuscany, Italy): Shell characters, live animals, and a molecular analysis of egg masses
FIGURE 1: Phylogenetic tree based on an analysis of the entire data set (H3, COI, 16S, and 18S sequences) of all specimens listed in Table 2. The phylogenetic model (GTR+I+G) was estimated by MrModeltest (Nylander 2004) performed with Paup*4.0b10 (Swofford 2003). Protein coding data sets were coded as "CODON". Based on different base compositions (chi-square test) in each of the single data sets, all parameters were defined as unlinked. Paup*4.0b10 tree characteristics: RI=0.851, CI=0.579. 325 positions were parsimony-informative, 76 were parsimony-uninformative, and 1141 were constant (1542 bp). Tonna cerevisina (Hedley, 1919) and Cypraea annulus (Linnaeus, 1758) were used as outgroup.
