Reconstructible phylogenetic networks: do not distinguish the indistinguishable. [PDF]
PLoS Computational Biology, 2015 Phylogenetic networks represent the evolution of organisms that have undergone reticulate events, such as recombination, hybrid speciation or lateral gene transfer. An important way to interpret a phylogenetic network is in terms of the trees it displays,

Different evolutionary trajectories of vaccine-controlled and non-controlled avian infectious bronchitis viruses in commercial poultry. [PDF]
PLoS ONE, 2017 To determine the genetic and epidemiological relationship of infectious bronchitis virus (IBV) isolates from commercial poultry to attenuated live IBV vaccines we conducted a phylogenetic network analysis on the full-length S1 sequence for Arkansas (Ark),

Biochemical and phylogenetic networks-II: X-trees and phylogenetic trees [PDF]
Journal of Mathematical Chemistry, 2021 The present study, which is a continuation of the previous paper, augments a recent work on the use of phylogenetic networks. We develop techniques to characterize the topology of various X-trees and binary trees of biological and phylogenetic interests. We have obtained the results for various k-level X-trees and phylogenetic networks with variants of

Algorithms for visualizing phylogenetic networks [PDF]
Theoretical Computer Science, 2016 We study the problem of visualizing phylogenetic networks, which are extensions of the Tree of Life in biology. We use a space filling visualization method, called DAGmaps, in order to obtain clear visualizations using limited space. In this paper, we restrict our attention to galled trees and galled networks and present linear time algorithms for ...

Kernelizations for the hybridization number problem on multiple nonbinary trees [PDF]
, 2016 Given a finite set $X$, a collection $\mathcal{T}$ of rooted phylogenetic trees on $X$ and an integer $k$, the Hybridization Number problem asks if there exists a phylogenetic network on $X$ that displays all trees from $\mathcal{T}$ and has reticulation

Inferring Phylogenetic Network of Malware Families Based on Splits Graph
IEICE Trans. Inf. Syst., 2017 Malware phylogeny refers to inferring the evolutionary relationships among instances of a family. It plays an important role in malware forensics. Previous works mainly focused on tree-based model.

On Computing the Maximum Parsimony Score of a Phylogenetic Network [PDF]
SIAM Journal on Discrete Mathematics, 2013 Phylogenetic networks are used to display the relationship among different species whose evolution is not treelike, which is the case, for instance, in the presence of hybridization events or horizontal gene transfers.

Extended Newick: it is time for a standard representation of phylogenetic networks
BMC Bioinformatics, 2008 Background Phylogenetic trees resulting from molecular phylogenetic analysis are available in Newick format from specialized databases but when it comes to phylogenetic networks, which provide an explicit representation of reticulate evolutionary events ...

The agreement distance of unrooted phylogenetic networks
, 2020 A rearrangement operation makes a small graph-theoretical change to a phylogenetic network to transform it into another one. For unrooted phylogenetic trees and networks, popular rearrangement operations are tree bisection and reconnection (TBR) and ...

Which phylogenetic networks are merely trees with additional arcs? [PDF]
, 2015 A binary phylogenetic network may or may not be obtainable from a tree by the addition of directed edges (arcs) between tree arcs. Here, we establish a precise and easily tested criterion (based on `2-SAT') that efficiently determines whether or not any ...
