Making a Network Orchard by Adding Leaves

Leo van Iersel, Mark Jones, Esther Julien +1

Phylogenetic networks are used to represent the evolutionary history of species. Recently, the new class of orchard networks was introduced, which were later shown to be interpreta…

A Near-Linear Kernel for Two-Parsimony Distance

Elise Deen, Leo van Iersel, Remie Janssen +3

The maximum parsimony distance and the bounded-state maximum parsimony distance measure the difference between two phylogene…

Embedding phylogenetic trees in networks of low treewidth

Leo van Iersel, Mark Jones, Mathias Weller

Given a rooted, binary phylogenetic network and a rooted, binary phylogenetic tree, can the tree be embedded into the network? This problem, called \textsc{Tree Containment}, arise…

Orchard Networks are Trees with Additional Horizontal Arcs

Leo van Iersel, Remie Janssen, Mark Jones +1

Phylogenetic networks are used in biology to represent evolutionary histories. The class of orchard phylogenetic networks was recently introduced for their computational benefits,…

Level- networks from shortest and longest distances

Katharina T. Huber, Leo van Iersel, Remie Janssen +3

Recently it was shown that a certain class of phylogenetic networks, called level- networks, cannot be reconstructed from their associated distance matrices. In this paper, we s…

Distinguishing level-1 phylogenetic networks on the basis of data generated by Markov processes

Elizabeth Gross, Leo van Iersel, Remie Janssen +3

Phylogenetic networks can represent evolutionary events that cannot be described by phylogenetic trees. These networks are able to incorporate reticulate evolutionary events such a…
