Evolutionary history of the Galápagos Rail revealed by ancient mitogenomes and modern samples
<p>Beast v. 2.6.3 input (<em>.xml</em>) files and output (<em>.log</em> and <em>.trees</em>) files for phylogenetic analyses of rails, used to determined the evolutionary history of the Galápagos Rail <em>Laterallus spilonota</em>. There are two main datasets: coding sequences of the mitochondrial genome ('mtCDS'), partitioned per codon position, and a two mitochondrial/one nuclear marker dataset ('2mt1nc'). For each of the datasets, separate runs have been made in which the fossil calibration of Rallidae is applied to the stem of the present-day family ('calRallidaeStem') or the crown node ('calRallidaeCrown), and finally all runs have been replicated with three different starting seeds ('seed_NNNNNNNNN', with the different seeds 123456789, 456789123, and 789123456).</p> <p>We provide raw output (<em>.log</em> and <em>.raw.trees</em>) as well as maximum clade credibility ('mcc') trees (<em>.mcc.trees</em>), calculated after discarding 10% of the trees as burn-in, using median ('heights_median') or mean ('heights_mean') node heights as estimated node age.</p> <p>The runs used for Table 1 (and Figure 2) in the accompanying paper are:</p> <ul> <li>Dataset mtCDS, Rallidae calibration of stem: seed 123456789</li> <li>Dataset mtCDS, Rallidae calibration of crown: seed 456789123 </li> <li>Dataset 2mt1nc, Rallidae calibration of stem: seed 789123456</li> <li>Dataset 2mt1nc, Rallidae calibration of crown: seed 123456789</li> </ul> <p>This version of the data includes <em>Pellornis mikkelseni</em> among the fossils making up the calibration distribution for crown Gruiformes. In a previous version of this data deposit, that data point was represented by <em>Messelornis cristata </em>(see accompanying paper).</p>
