Phylogeny-based metrics of biodiversity: concepts and methods
Kristina Wicke, Arne Mooers
The concept of valuing evolutionary history has a long tradition and was formalized by several research groups in the early 1990s, each aiming to capture the products of evolution…
Revisiting a random model of lateral gene transfer in phylogenetics
Laura Kubatko, Simone Linz, Kristina Wicke
Processes such as incomplete lineage sorting (ILS) and reticulate evolution (arising, for example, from hybridization and lateral gene transfer (LGT)) are known to cause discordanc…
Properties of biodiversity indices that incorporate future extinction risk
Mike Steel, Kristina Wicke, Arne Mooers
The loss of biodiversity due to the likely widespread extinction of species in the near future is a focus of current concern in conservation biology. One approach to measure the im…
A sharp lower bound for the number of phylogenetic trees displayed by a tree-child network
Charles Semple, Kristina Wicke
A normal (phylogenetic) network with reticulations displays phylogenetic trees. In this paper, we establish an analogous result for tree-child (phylogenetic) networks wit…
Order-Dependent Dissimilarity Measures on Phylogenetic Trees
Simone Linz, Katherine St. John, Charles Semple +1
Ordered leaf attachment, Phylo2Vec, and HOP are three recently introduced vector representations for rooted phylogenetic trees where the representation is determined by an ordering…
Distinguishing Phylogenetic Level-2 Networks with Quartets and Inter-Taxon Quartet Distances
Niels Holtgrefe, Elizabeth S. Allman, Hector Baños +4
The inference of phylogenetic networks, which model complex evolutionary processes including hybridization and gene flow, remains a central challenge in evolutionary biology. Until…
Bounding the softwired parsimony score of a phylogenetic network
Janosch Döcker, Simone Linz, Kristina Wicke
In comparison to phylogenetic trees, phylogenetic networks are more suitable to represent complex evolutionary histories of species whose past includes reticulation such as hybridi…
Phylogenetic diversity indices from an affine and projective viewpoint
Vincent Moulton, Andreas Spillner, Kristina Wicke
Phylogenetic diversity indices are commonly used to rank the elements in a collection of species or populations for conservation purposes. The derivation of these indices is typica…
