DISSECT: an assignment-free Bayesian discovery method for species delimitation under the multispecies coalescent
Jones, Graham; Aydin, Zeynep; Oxelman, Bengt (Oxford Univ Press, 2015)Motivation: The multispecies coalescent model provides a formal framework for the assignment of individual organisms to species, where the species are modeled as the branches of the sp tree. None of the available approaches ... -
Marginal Likelihood Estimate Comparisons to Obtain Optimal Species Delimitations in Silene sect. Cryptoneurae (Caryophyllaceae)
Aydın, Zeynep; Marcussen, Thomas; Ertekin, Alaattin Selçuk; Oxelman, Bengt (PUBLIC LIBRARY SCIENCE, 1160 BATTERY STREET, STE 100, SAN FRANCISCO, CA 94111 USA, 2014)Coalescent-based inference of phylogenetic relationships among species takes into account gene tree incongruence due to incomplete lineage sorting, but for such methods to make sense species have to be correctly delimited. ... -
A new section of Silene (Caryophyllaceae) including a new species from South Anatolia, Turkey
Aydin, Zeynep; Ertekin, Alaattin Selcuk; Langstrom, Elisabeth; Oxelman, Bengt (Magnolia Press, 2014)Silene section Cryptoneurae (Caryophyllaceae) and S. ertekinii from Western Antalya, Turkey, are described as new taxa on the basis of morphological and molecular investigations. Nuclear ITS and chloroplast rps16 DNA ... -
Recombination provides evidence for ancient hybridisation in the Silene aegyptiaca (Caryophyllaceae) complex
Pfeil, Bernard E.; Toprak, Zeynep; Oxelman, Bengt (Springer Verlag, 2017)Recombination events among distinct alleles complicate phylogenetic estimation. Various in vivo and in vitro processes can bring distinct alleles into the same genome to then undergo recombination, which may subsequently ... -
Species delimitation without prior knowledge: DISSECT reveals extensive cryptic speciation in the Silene aegyptiaca complex (Caryophyllaceae)
Toprak, Zeynep; Pfeil, Bernard E.; Jones, Graham; Marcussen, Thomas; Ertekin, Alaattin Selcuk; Oxelman, Bengt (Academic Press Inc Elsevier Science, 2016)Species delimitation is a major focus of biosystematics. In recent years, considerable progress has been achieved with the development of the multispecies coalescent (MSC) model, where species constitute the branches of ...
