摘要:

Abstract—A cladistic analysis of the “blue ash” eucalypts (Eucalyptus, Myrtaceae) is presented. Five equally parsimonious trees were found, and a strict consensus tree constructed. A revised informal classification, recognizing five series (Planchonianinae, Sphaerocarpinae, Piperitinae, FraxininaeandHaemastominae, informal subgenusMonocalyptus) is based on the consensus cladogram. A biogeographic analysis applies a new implementation of Assumptions 0 and 1, coding data in the form of three‐area statements and using parsimony analysis. These results are used to evaluate hand resolution of Assumption 2. In comparison, Brooks parsimony analysis did not produce area cladograms that best fit the data. Series and subseries were analysed separately for area relationships, which showed a repeated pattern across the blue ash clade; combining all the data in one analysis was seen as equivalent to confounding paralogy and orthology in molecular studies. A resolved area cladogram is presented for southeastern Au

摘要:

Abstract—Two data sets for 10 species of African milkweed butterflies (Nymphalidae, Danainae: oneDanaus, twoTirumala, sevenAmauris) have been analysed cladistically, separately and in combination. One data set comprised 32 morphological characters, the other comprised 68 chemical compounds from male scent organs. Analysed separately, the two data sets produced six similar but non‐identical minimum‐length solutions. Analysed together, the combined data set of 100 characters produced a single minimum‐length tree, identical to one of the three solutions for the morphological data set. The combined data produced a more informative result than congruence comparisons based on strict or combinable component consensus analysis. These results, together with re‐analysis of a morphological data set for all 15 species ofAmauris(which produced 12 minimum‐length solutions), permit increased resolution of the existing classification of this Afrotropical genus, including the formal recognition of two subgenera,Amauris(Amauris) Hübner, andAmauris(Amaura) Geyer (stat. rev.). The fit of uniquely derived, unreversed chemical characters to the tree raises the possibility that stepwise additive evolution of semiochemicals may have occurred during cladogenesis of these mimetic butterflies. The implications for chemoecology and speciation are brief
