Given their small size and high rate of evolution, several considerations should be kept in mind when applying comparative molecular forensic analyses to viruses.
The objectives of this study were to sequence the genome of φ24B and apply comparative genomic analyses to highlight important genetic similarities and differences across the Stx phages sequenced to date.
Techniques applied for comparative analyses included paired-end fosmid mapping from one genome onto the others, comparisons of large contigs (>50 kb) on the DNA and protein sequence level, and the identification of core gene sets shared between the three genomes.
We apply phylogenetic comparative analyses to disentangle the evolutionary patterns of ecological niches in an assemblage of European birds.
The software applies comparative quantification with an adaptive baseline.
The early burst model of divergence has been applied widely in comparative analyses of adaptive radiation (e.g. [ 7- 10]), but a growing body of research is now also making use of evolutionary models based on a Simpsonian adaptive landscape (e.g. [ 11- 14]).
A 'one-group pretest-posttest, with a non-equivalent posttest-only comparison group design' is used to quantitatively evaluate the impact of the transition programme, applying both longitudinal and comparative analyses.
Users can simultaneously link a minimum of two datasets at various functional and taxonomic levels for comparative analyses through applying multiple clustering methods.
In comparative analyses, we applied Student's t-test to parametric variables, Kruskal Wallis test to nonparametric continuous variables and chi-squared test to categorical variables.
In the comparative analyses we applied a generalized least squares regression method in a phylogenetic framework [45], [46] with the phylogeny of species shown in Fig. 1.
In addition, similar comparative analyses have been applied to metagenomic datasets, in which genomic fragments were assigned to their probable host based on their compositional similarities [ 26, 27].
