Phylogenetic Networks with Every Embedded Phylogenetic Tree a Base Tree

Bulletin of Mathematical Biology, 2016
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.

Comparison of phylogenetic trees

Mathematical Biosciences, 1981
Abstract A metric on general phylogenetic trees is presented. This extends the work of most previous authors, who constructed metrics for binary trees. The metric presented in this paper makes possible the comparison of the many nonbinary phylogenetic trees appearing in the literature.

An approximately unbiased test of phylogenetic tree selection.

Systematic Biology, 2002
An approximately unbiased (AU) test that uses a newly devised multiscale bootstrap technique was developed for general hypothesis testing of regions in an attempt to reduce test bias.

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 ...

Phylogenetic trees in ACL2 [PDF]

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 ...

Constructing a Phylogenetic Tree

2014
In this project I constructed a workflow that takes a DNA sequence as input and provides a phylogenetic tree, consisting of the input sequence and other sequences which were found during a database search. In this phylogenetic tree the sequences are arranged depending on similarities.

Groves of Phylogenetic Trees

Annals of Combinatorics, 2009
A major challenge in biological sciences is the reconstruction of the Tree of Life. To this effect, large genomic databases like GenBank and SwissProt are being mined for clusters from which phylogenies can be inferred. Systematists and comparative biologists commonly combine such phylogenies into informative supertrees that reveal information which ...
