A Phylogenetic Analysis of Cunoniaceae

Systematic Botany, 1992
We present a cladistic analysis of genera of Cunoniaceae based on 44 structural characters using Wagner parsimony.

A Phylogenetic Analysis of the Allometry of Diving

The American Naturalist, 2006
The oxygen store/usage hypothesis suggests that larger animals are able to dive for longer and hence deeper because oxygen storage scales isometrically with body mass, whereas oxygen usage scales allometrically with an exponent

A Phylogenetic Analysis of Aquifex pyrophilus

Systematic and Applied Microbiology, 1992
The 16S rRNA of the bacterion Aquifex pyrophilus, a microaerophilic, oxygen-reducing hyperthermophile, has been sequenced directly from the the PCR amplified gene. Phylogenetic analyses show the Aq. pyrophilus lineage to be probably the deepest (earliest) in the (eu)bacterial tree.

A phylogenetic analysis of the phylum Fibrobacteres

Systematic and Applied Microbiology, 2013
Members of the phylum Fibrobacteres are highly efficient cellulolytic bacteria, best known for their role in rumen function and as potential sources of novel enzymes for bioenergy applications. Despite being key members of ruminants and other digestive microbial communities, our knowledge of this phylum remains incomplete, as much of our understanding ...

Phylogenetic analysis of anthropoid relationships

Journal of Human Evolution, 1998
The relationships of anthropoids to other primates are currently debated, as are the relationships among early fossil anthropoids and crown anthropoids. To resolve these issues, data on 291 morphological characters were collected for 57 taxa of living and fossil primates and analyzed using PAUP and MacClade.

Phylogenetic analysis ofUlmaceae

Plant Systematics and Evolution, 1996
A phylogenetic analysis of theUlmaceae, Cannabaceae, Barbeyaceae, andBroussonetia of theMoraceae produced nine equally parsimonious trees with 127 steps. TheUlmoideae (Ulmaceae, sensuGrudzinskaya) are a monophyletic group and distinct from theCeltidoideae. The genusAmpelocera occupies an isolated taxonomic position among the celtidoids.

QUANTITATIVE CHARACTERS IN PHYLOGENETIC ANALYSIS [PDF]

open access: possibleCladistics, 1989
Abstract— When analysing phylogcnetic relationships at low laxonomic levels it is often the ease that many of the features that can be used to separate taxa show continuous variation. The theoretical and practical problems for the use of such quantitative characters in phylogenetic analysis arc examined.

Phylogenetic Analysis of Pathogens

2011
Publisher Summary This chapter introduces the important facets of the topic of producing phylogenetic trees, and the direct relevance to the study of infectious organisms' transmission. It is clearly important to be able to reconstruct the phylogeny, both for a group of species and also for the individuals within those species.

Phylogenetic Analysis

2014
The chapter briefly discusses the principles of phylogenetic analysis. The phylogenetic tree and its various parts are explained. The steps involved in the construction of a phylogenetic tree are briefly reviewed. Some online tools are mentioned that users can employ to reconstruct the phylogenetic tree of their desired set of sequences.

Phylogenetic Analysis of Poliovirus Sequences

2016
Comparative genomic sequencing is a major surveillance tool in the Polio Laboratory Network. Due to the rapid evolution of polioviruses (~1 % per year), pathways of virus transmission can be reconstructed from the pathways of genomic evolution. Here, we describe three main phylogenetic methods; estimation of genetic distances, reconstruction of a ...
