  • PartitionFinder 2:New Methods for Selecting Partitioned Models of Evolution for Molecular and Morphological Phylogenetic Analyses

    Lanfear, Robert   Frandsen, Paul B.   Wright, April M.   Senfeld, Tereza   Calcott, Brett  

    PartitionFinder 2 is a program for automatically selecting best-fit partitioning schemes and models of evolution for phylogenetic analyses. PartitionFinder 2 is substantially faster and more efficient than version 1, and incorporates many new methods and features. These include the ability to analyze morphological datasets, new methods to analyze genome-scale datasets, new output formats to facilitate interoperability with downstream software, and many new models of molecular evolution. PartitionFinder 2 is freely available under an open source license and works on Windows, OSX, and Linux operating systems. It can be downloaded from The source code is available at

  • Taxonomic status of the extinct Canary Islands Oystercatcher Haematopus meadewaldoi

    Senfeld, Tereza   Shannon, Thomas J.   Heinvangrouw   Paijmans, Dane M.   Tavares, Erika S.   Baker, Allan J.   Lees, Alexander C.   Collinson, J. Martin  

    Mitochondrial genes were sequenced from four specimens of the extinct Canary Islands Oystercatcher Haematopus meadewaldoi and compared with African Oystercatcher Haematopus moquini, Eurasian Oystercatcher Haematopus ostralegus and an old unidentified extralimital 'black' oystercatcher specimen from The Gambia. At these loci, H. meadewaldoi was approximately 99.65% identical to multiple Eurasian Oystercatcher samples and in phylogenetic trees fell within the range of genetic variation observed in that species. The mystery Gambian bird was resolved as an extralimital H. moquini. We conclude that H. meadewaldoi was most likely a recently diverged melanistic morph or subspecies of H. ostralegus, although further genomic studies will be required to determine whether there has been a period of isolation followed by introgression.
