(1974) A new look at the statistical model identification. (2012) BEAGLE: An application programming interface and high-performance computing library for statistical phylogenetics. sylvaticum as different species.Īyres, D.L., Darling, A., Zwickl, D.J., Beerli, P., Holder, M.T., Lewis, P.O., Huelsenbeck, J.P., Ronquist, F., Swofford, D.L., Cummings, M.P., Rambaut, A. In accordance with the morphological approach of Tarıkahya-Hacıoğlu and Erik, the species delimitation analyses based on molecular data support the recognition of S. The TCS and GMYC analyses demonstrated more complicated clusters, whereas high posterior probabilities of BPP clusters were more compatible with the morphological data. ibericum, which is phylogenetically nested within the S. In addition to members of this complex, S. To solve this uncertainty, different species delimitation methods were used, including statistical parsimony network analysis (TCS), generalized mixed Yule coalescent (GMYC), and Bayesian Phylogenetics and Phylogeography (BPP) of the ITS, trnL-F and trnS-G sequence data. sepulcrale), which was assigned as a member of this complex by Kurtto, has been regarded as unresolved. However, the taxonomical status of some of these species (i.e., S. sylvaticum, after the phylogenetic and morphological studies of Tarıkahya-Hacıoğlu and Erik. The number of species was reduced to three, comprising S. However, according to further studies by different researchers based on morphological data, total number of species of the complex was variable. Symphytum asperum aggregate was first introduced by Kurtto, who proposed six taxa within this aggregate. In addition to different infrageneric classification methods, several species complex or aggregates have been proposed to deal with the taxonomical problem of genus members. Symphytum is regarded one of the most complicated genera in terms of the classification of its members among the Boraginaceae.
