Approximate Maximum Parsimony and Ancestral Maximum Likelihood [PDF]
We explore the maximum parsimony (MP) and ancestral maximum likelihood (AML) criteria in phylogenetic tree reconstruction. Both problems are NP-hard, so we seek approximate solutions. We formulate the two problems as Steiner tree problems under appropriate distances. The gist of our approach is the succinct characterization of Steiner trees for a small

Haplotype inference by maximum parsimony [PDF]
Abstract Motivation: Haplotypes have been attracting increasing attention because of their importance in analysis of many fine-scale molecular-genetics data. Since direct sequencing of haplotype via experimental methods is both time-consuming and expensive, haplotype inference methods that infer haplotypes based on genotype samples ...

A comparison of phylogenetic network methods using computer simulation. [PDF]
We present a series of simulation studies that explore the relative performance of several phylogenetic network approaches (statistical parsimony, split decomposition, union of maximum parsimony trees, neighbor-net, simulated history recombination upper ...

Owing to the largely unexplored diversity of metazoan parasites, their speciation mechanisms and the circumstances under which such speciation occurs – in allopatry or sympatry – remain vastly understudied.

Evaluating multi-locus phylogenies for species boundaries determination in the genus Diaporthe [PDF]
Background Species identification is essential for controlling disease, understanding epidemiology, and to guide the implementation of phytosanitary measures against fungi from the genus Diaporthe.

Multiple optimality criteria support Ornithoscelida [PDF]
A recent study of early dinosaur evolution using equal-weights parsimony recovered a scheme of dinosaur interrelationships and classification that differed from historical consensus in a single, but significant, respect; Ornithischia and Saurischia were ...

The Evaluations Of Taxonomic Classifications In The Genus Trifolium L. Based On ITS Sequences
The genus Trifolium L. belonging to family Fabaceae is represented by about 255 species in the world. Two classifications based on the sections or subgenus are commonly used by the researchers in the taxonomically evaluation of the genus Trifolium ...

Inconsistency of Maximum Parsimony Revisited [PDF]
Felsenstein (1978, Syst. Zool. 27:401-410) showed that the method of maximum parsimony can be inconsistent, i.e., lead to an incorrect result with an infinite amount of data. The situation in which this inconsistency occurs is often called the "Felsenstein zone," the phenomenon also known as "long-branch attraction." Felsenstein derived a sufficient ...

The relationships of the Euparkeriidae and the rise of Archosauria [PDF]
For the first time, a phylogenetic analysis including all putative euparkeriid taxa is conducted, using a large data matrix analysed with maximum parsimony and Bayesian analysis. Using parsimony, the putative euparkeriid Dorosuchus neoetus from Russia is
