Fig. 3 in Phylogenetic evidence for multiple independent origins of functional kleptoplasty in Sacoglossa (Heterobranchia, Gastropoda)
Fig. 3 Phylogeny of the Sacoglossa based on Bayesian analysis (50 % majority rule consensus tree). Numbers at nodes indicate Posterior Probability (PP), black circles indicate PP=100, and black asterisks indicate PP=95–99. The inner dark gray circle borders functional-retention information of taxa, the outer food sources (displayed are only three major food sources per species). The scale bar displays substitutions per site. Yellow highlighted is the "outgroup", pink the Oxynoacea, purple the Platyhedylidae, green the " Limapontioidea ", and blue the
Fig. 2 in Phylogenetic evidence for multiple independent origins of functional kleptoplasty in Sacoglossa (Heterobranchia, Gastropoda)
Fig. 2 Maximum quantum yield measurements (Fv/Fm) of Elysia clarki. Specimens of E. clarki were either starved under 40 μmol quanta m−2 s−1 (diamonds) or in complete darkness (rectangles) over a period of 49 days. Error bars indicate standard deviation between different specimens for each measuring point. Because specimens were fixed at certain intervals, finally only one individual was left at day 49
