Unraveling the rapid radiation of crested newts, Triturus cristatus superspecies, using complete mitogenomic sequences [PDF]

open access: yes, 2011
Background - The rapid radiation of crested newts (Triturus cristatus superspecies) comprises four morphotypes: 1) the T. karelinii group, 2) T. carnifex - T. macedonicus, 3) T. cristatus and 4) T. dobrogicus.

Towards the plastome evolution and phylogeny of Cycas L. (Cycadaceae): molecular-morphology discordance and gene tree space analysis

open access: yesBMC Plant Biology, 2022
Background Plastid genomes (plastomes) present great potential in resolving multiscale phylogenetic relationship but few studies have focused on the influence of genetic characteristics of plastid genes, such as genetic variation and phylogenetic ...

Realistic Gene Transfer to Gene Duplication Ratios Identify Different Roots in the Bacterial Phylogeny Using a Tree Reconciliation Method

open access: yesLife, 2022
The rooting of phylogenetic trees permits important inferences about ancestral states and the polarity of evolutionary events. Recently, methods that reconcile discordance between gene-trees and species-trees—tree reconciliation methods—are becoming ...

Factors affecting the concordance between orthologous gene trees and species tree in bacteria

open access: yesBMC Evolutionary Biology, 2008
Background As originally defined, orthologous genes implied a reflection of the history of the species. In recent years, many studies have examined the concordance between orthologous gene trees and species trees in bacteria.

Target capture data resolve recalcitrant relationships in the coffee family (Rubioideae, Rubiaceae)

open access: yesFrontiers in Plant Science, 2022
Subfamily Rubioideae is the largest of the main lineages in the coffee family (Rubiaceae), with over 8,000 species and 29 tribes. Phylogenetic relationships among tribes and other major clades within this group of plants are still only partly resolved ...

Genomic variation in a widespread Neotropical bird (Xenops minutus) reveals divergence, population expansion, and gene flow [PDF]

open access: yes, 2014
Elucidating the demographic and phylogeographic histories of species provides insight into the processes responsible for generating biological diversity, and genomic datasets are now permitting the estimation of histories and demographic parameters with ...

Reconciling taxonomy and phylogenetic inference: formalism and algorithms for describing discord and inferring taxonomic roots [PDF]

open access: yes, 2011
Although taxonomy is often used informally to evaluate the results of phylogenetic inference and find the root of phylogenetic trees, algorithmic methods to do so are lacking.

Genome-wide signatures of complex introgression and adaptive evolution in the big cats. [PDF]

open access: yes, 2017
The great cats of the genus Panthera comprise a recent radiation whose evolutionary history is poorly understood. Their rapid diversification poses challenges to resolving their phylogeny while offering opportunities to investigate the historical ...
