Species delimitation in Aspergillus felis clade based on six genetic loci

Schematic representation of results of species delimitation methods in Aspergillus felis clade based on six genetic loci. The results of multilocus method (STACEY) are compared to results of single-locus methods (mPTP, bGMYC, GMYC). The results of STACEY are shown as tree branches with different colours, while the results of single-locus methods are depicted with coloured bars highlighting congruence across methods. The displayed tree is derived from IQtree analysis based on a concatenated dataset and is used solely for the comprehensive presentation of the results from different methods. The species validation analysis results (BP&P) are appended to nodes and shown in gray bordered boxes; the values represent posterior probabilities calculated in three scenarios having different prior distributions of parameters θ (ancestral population size) and τ0 (root age). The top value represents the results of analysis with large ancestral population sizes and deep divergence: θ ~ G (1, 10) and τ0 ~ G (1, 10), the middle value ); large ancestral populations sizes and shallow divergences among species: θ ~ G (1, 10) and τ0 ~ G (2, 2000) and the bottom value small ancestral population sizes and shallow divergences among species: θ ~ G (2, 2000) and τ0 ~ G (2, 2000).
