A phylogenetic analysis of Legionella
Archives of Microbiology, 1983Four species of Legionella, L. pneumophila NCTC 11192, L. bozemanii NCTC 11368, L. micdadei NCTC 11371 and L. jordanis ATCC 33623 have been characterized by oligonucleotide cataloguing of their 16S ribosomal RNA. All four species are phylogenetically closely related, while no specific relationship could be detected with any other group of organisms ...

Phylogenetic analysis of the caliciviruses
Journal of Medical Virology, 1997A phylogenetic portrait of the genus Calicivirus in the family Caliciviridae was developed based upon published sequences and newly characterized calicivirus (CV) strains, including additional Sapporo-like HuCV strains in pediatric diarrhea stool specimens from South Africa, the United Kingdom, and the United States. Distance and parsimony methods were

Evolution, 2008
Meta-analysis is a powerful statistical technique that combines the results of independent studies to identify general trends. When the species under examination are not independent however, it is also necessary to incorporate phylogenetic information into the analysis.

Microcomputers and Phylogenetic Analysis
Science, 1986The programs discussed above show how microcomputers have added to the arsenal of systematic biologists. This is a rapidly developing field, and there are no doubt major changes on the horizon. Swofford is working on a new version of PAUP that will have some of the interactive features of MacClade (and will not require a math coprocessor) and there are

Improving the analysis of phylogenetic data
Computers & Chemistry, 1996Methods of phylogenetic analysis are presented that result in corrections of highly biased data sets, particularly those in which there are great differences between mutation and/or substitution rates from one nucleotide site to another along a DNA sequence. Two approaches are discussed. In the first, pairwise comparisons of a set of sequences are used

Combining data in phylogenetic analysis
Trends in Ecology & Evolution, 1996Systematists have access to multiple sources of character information in phylogenetic analysis. For example, it is not unusual to have nucleotide sequences from several different genes, or to have molecular and morphological data. How should diverse data be analyzed in phylogenetic analysis?

The marsupial placenta: A phylogenetic analysis
Journal of Experimental Zoology Part A: Comparative Experimental Biology, 2003AbstractThe structure, physiology, and endocrinology of the yolk sac placenta of different marsupial groups is compared and phylogenetically analyzed to provide information on placental characters in the marsupial stem species. We conclude that the marsupial stem species possessed a functional yolk sac placenta.

A phylogenetic analysis of the phylum Fibrobacteres
Systematic and Applied Microbiology, 2013Members 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 Survival Analysis
Going back in time through a phylogenetic tree makes it possible to evaluate ancestral genomes and assess their potential to acquire key polymorphisms of interest over evolutionary time. Knowledge of this kind may allow for the emergence of key traits to be predicted and pre-empted from currently circulating strains in the future.Arturo, Torres Ortiz, Louis, Grandjean
