Osmundales diverstity through time: stacking networks

2017-07-31T14:01:34Z (GMT) by Guido Grimm
This fileset includes stacked neighbour-net splits graphs (planar meta-phylogenetic networks) illustrating the taxic diversity change within the royal fern lineage (Osmundales) from the Permian to now. The networks are based on taxon subsets of the matrix compiled by <b><br>Bomfleur et al.,</b> <i>PeerJ</i> <b>5</b>: e3433, 2017, https://peerj.com/articles/3433/<br><u><b>Figures 1 and 2</b></u> show time-slice-wise networks, each network includes only species of one geological period. Permian, Triassic and Jurassic (Fig. 1); Cretaceous, Paleogene+Neogene, and modern-day (Fig. 2). Species names are abbreviated/contracted by three-letter codes. Higher taxa and according colouring of species (dot) follow Bomfleur et al. (2017). Refer to this study for basic inference methodology and information on the data.<br><u><b>Figures 3 to 6</b></u> show connected neighbour-nets, each including the species of two subsequent time-slices (older at bottom): Permian + Triassic and Triassic + Jurassic (Fig. 3); Triassic + Jurassic and Jurassic + Cretaceous (Fig. 4); Cretaceous + Paleogene and Paleogene + Neogene (Fig. 5); Paleogene + Neogene and Neogene + modern-day (Fig. 6).
