Efficient Reconstruction of Arboreal Networks
Katharina T. Huber, Katherine St. John
Arboreal networks are multi-rooted phylogenetic networks whose underlying graph is a tree. We give an encoding of stack-free arboreal networks in terms of triplets and the novel co…
Arboreal networks and their underlying trees
Katharina T. Huber, Darren Overman
Horizontal gene transfer (HGT) is an important process in bacterial evolution. Current phylogeny-based approaches to capture it cannot however appropriately account for the fact th…
Autopolyploidy, allopolyploidy, and phylogenetic networks with horizontal arcs
Katharina T. Huber, Liam J. Maher
Polyploidization is an evolutionary process by which a species acquires multiple copies of its complete set of chromosomes. The reticulate nature of the signal left behind by it me…
The hybrid number of a ploidy profile
Katharina T. Huber, Liam J. Maher
Polyploidization, whereby an organism inherits multiple copies of the genome of their parents, is an important evolutionary event that has been observed in plants and animals. One…
