Ancient incomplete lineage sorting of Hyles and Rhodafra (Lepidoptera: Sphingidae) [PDF]

Organisms Diversity & Evolution, 2020
AbstractThe hawkmoth genusRhodafracomprises two African species with unclear relationships, as their wing patterns are markedly different, with one species closely resembling species of a related genus,Hyles. The present paper aims to investigate the monophyly and phylogenetic position ofRhodafrain relation toHylesand other genera of the subtribe ...

Inferring incomplete lineage sorting, duplications, transfers and losses with reconciliations [PDF]

Journal of Theoretical Biology, 2017
Gene trees and species trees can be discordant due to several processes. Standard models of reconciliations consider macro-evolutionary events at the gene level: duplications, losses and transfers of genes. However, another common source of gene tree-species tree discordance is incomplete lineage sorting (ILS), whereby gene divergences corresponding to

Comparative genomics and phylogenetic discordance of cultivated tomato and close wild relatives [PDF]

PeerJ, 2015
Background. Studies of ancestry are difficult in the tomato because it crosses with many wild relatives and species in the tomato clade that have diverged very recently.

ASTRAL-III: polynomial time species tree reconstruction from partially resolved gene trees

BMC Bioinformatics, 2018
Background Evolutionary histories can be discordant across the genome, and such discordances need to be considered in reconstructing the species phylogeny.

Integrating phylogeographic and ecological niche approaches to delimitating cryptic lineages in the blue–green damselfish (Chromis viridis) [PDF]

PeerJ, 2019
Species delimitation is challenging in sibling species/cryptic lineages because of the absence of clear diagnostic traits. However, integration of different approaches such as phylogeography and ecological niche comparison offers one potential approach ...

Incomplete lineage sorting rather than hybridization explains the inconsistent phylogeny of the wisent. [PDF]

Commun Biol, 2018
AbstractThe wisent or European bison is the largest European herbivore and is completely cross-fertile with its American relative. However, mtDNA genome of wisent is similar to that of cattle, which suggests that wisent emerged as a hybrid of bison and an extinct cattle-like species.

The performance of coalescent-based species tree estimation methods under models of missing data

BMC Genomics, 2018
Background Estimation of species trees from multiple genes is complicated by processes such as incomplete lineage sorting, gene duplication and loss, and horizontal gene transfer, that result in gene trees that differ from each other and from the species

Widespread incomplete lineage sorting and introgression shaped adaptive radiation in the Gossypium genus. [PDF]

Plant Commun
Cotton (Gossypium) stands as a crucial economic crop, serving as the primary source of natural fiber for the textile sector. However, the evolutionary mechanisms driving speciation within the Gossypium genus remain unresolved. In this investigation, we leveraged 25 Gossypium genomes and introduced four novel assemblies-G. harknessii, G. gossypioides, G.

Duplicate Detection in Probabilistic Data [PDF]

, 2009
Collected data often contains uncertainties. Probabilistic databases have been proposed to manage uncertain data. To combine data from multiple autonomous probabilistic databases, an integration of probabilistic data has to be performed.
