Polyploidy breaks speciation barriers in Australian burrowing frogs Neobatrachus [PDF]
, 2020 Polyploidy has played an important role in evolution across the tree of life but it is still unclear how polyploid lineages may persist after their initial formation.

Diversity, 2023 The analysis of phylogeographic patterns has often been based on mitochondrial DNA variation, but recent analyses dealing with nuclear DNA have in some instances revealed mito-nuclear discordances and complex evolutionary histories.

Linking great apes genome evolution across time scales using polymorphism-aware phylogenetic models [PDF]
, 2017 The genomes of related species contain valuable information on the history of the considered taxa. Great apes in particular exhibit variation of evolutionary patterns along their genomes. However, the great ape data also bring new challenges, such as the

Reticulate evolutionary history of a complex group of grasses: phylogeny of Elymus StStHH allotetraploids based on three nuclear genes. [PDF]
PLoS ONE, 2010 BACKGROUND: Elymus (Poaceae) is a large genus of polyploid species in the wheat tribe Triticeae. It is polyphyletic, exhibiting many distinct allopolyploid genome combinations, and its history might be further complicated by introgression and lineage ...

An HMM-based Comparative Genomic Framework for Detecting Introgression in Eukaryotes [PDF]
, 2013 One outcome of interspecific hybridization and subsequent effects of evolutionary forces is introgression, which is the integration of genetic material from one species into the genome of an individual in another species.

A polynomial time algorithm for calculating the probability of a ranked gene tree given a species tree [PDF]
, 2012 In this paper, we provide a polynomial time algorithm to calculate the probability of a {\it ranked} gene tree topology for a given species tree, where a ranked tree topology is a tree topology with the internal vertices being ordered. The probability of

Using supernetworks to distinguish hybridization from lineage-sorting
BMC Evolutionary Biology, 2008 Background A simple and widely used approach for detecting hybridization in phylogenies is to reconstruct gene trees from independent gene loci, and to look for gene tree incongruence.

Inferring duplications, losses, transfers and incomplete lineage sorting with nonbinary species trees. [PDF]
Bioinformatics, 2012 Abstract Motivation: Gene duplication (D), transfer (T), loss (L) and incomplete lineage sorting (I) are crucial to the evolution of gene families and the emergence of novel functions. The history of these events can be inferred via comparison of gene and species trees, a process called reconciliation, yet current reconciliation ...

Species Limits and Phylogeography of North American Cricket Frogs (Acris: Hylidae) [PDF]
, 2008 Cricket frogs are widely distributed across the eastern United States and two species, the northern cricket frog (Acris crepitans) and the southern cricket frog (A. gryllus) are currently recognized. We generated a phylogenetic hypothesis for Acris using
