Phylogenetic Networks with Every Embedded Phylogenetic Tree a Base Tree

Bulletin of Mathematical Biology, 2015
We show that the class of tree-child networks is precisely the class of tree-based networks with the property that every embedded phylogenetic tree is a base tree.

On Tree-Based Phylogenetic Networks [PDF]

Journal of Computational Biology, 2016
A large class of phylogenetic networks can be obtained from trees by the addition of horizontal edges between the tree edges. These networks are called tree based networks. Reticulation-visible networks and child-sibling networks are all tree based. In this work, we present a simply necessary and sufficient condition for tree-based networks and prove ...

Phylogenetic trees in ACL2

Proceedings of the sixth international workshop on the ACL2 theorem prover and its applications - ACL2 '06, 2006
Biologists studying the evolutionary relationships between organisms use software packages to solve the computational problems they encounter. Several of these problems involve the production and analysis of phylogenetic trees. We present our system for phylogenetic tree manipulation, TASPI, which was designed to allow the specification and ...

Statistics for phylogenetic trees

Theoretical Population Biology, 2003
This paper poses the problem of estimating and validating phylogenetic trees in statistical terms. The problem is hard enough to warrant several tacks: we reason by analogy to rounding real numbers, and dealing with ranking data. These are both cases where, as in phylogeny the parameters of interest are not real numbers.

Phylogenetic tree-building

International Journal for Parasitology, 1996
Cladistic analysis is an approach to phylogeny reconstruction that groups taxa in such a way that those with historically more-recent ancestors form groups nested within groups of taxa with more-distant ancestors. This nested set of taxa can be represented as a branching diagram or tree (a cladogram), which is an hypothesis of the evolutionary history ...
