Delimiting species without nuclear monophyly in Madagascar's mouse lemurs. [PDF]

open access: yesPLoS ONE, 2010
Speciation begins when populations become genetically separated through a substantial reduction in gene flow, and it is at this point that a genetically cohesive set of populations attain the sole property of species: the independent evolution of a ...

Integrating the processes in the evolutionary system of domestication [PDF]

open access: yes, 2010
Genetics has long been used as a source of evidence to understand domestication origins. A recent shift in the emphasis of archaeological evidence from a rapid transition paradigm of hunter-gatherers to agriculturalists, to a protracted transition ...

Testing the monophyly of Heterosperma (Asteraceae, Coreopsideae)

open access: yesPhytotaxa, 2018
The genus Heterosperma (Asteraceae, Coreopsideae) currently comprises ten species distributed from Mexico to South America. Molecular phylogenies of the tribe Coreopsideae (including only two species of Heterosperma) pointed out that the genus would not be monophyletic.

Going nuclear: gene family evolution and vertebrate phylogeny reconciled [PDF]

open access: yes, 2002
Gene duplications have been common throughout vertebrate evolution, introducing paralogy and so complicating phylogenctic inference from nuclear genes.

Waves of genomic hitchhikers shed light on the evolution of gamebirds (Aves: Galliformes) : research article [PDF]

open access: yes, 2007
Background The phylogenetic tree of Galliformes (gamebirds, including megapodes, currassows, guinea fowl, New and Old World quails, chicken, pheasants, grouse, and turkeys) has been considerably remodeled over the last decades as new data and analytical ...

The changing views on the evolutionary relationships of extant Salamandridae (Amphibia: Urodela). [PDF]

open access: yesPLoS ONE, 2018
The phylogenetic relationships among members of the family Salamandridae have been repeatedly investigated over the last 90 years, with changing character and taxon sampling. We review the changing composition and the phylogenetic position of salamandrid

Molecular phylogeny and diversification history of Prosopis (Fabaceae: Mimosoideae) [PDF]

open access: yes, 2008
The genus Prosopis is an important member of arid and semiarid environments around the world. To study Prosopis diversification and evolution, a combined approach including molecular phylogeny, molecular dating, and character optimization analysis was ...

The genus problem – Eucalyptus as a model system for minimising taxonomic disruption

open access: yesTAXON, EarlyView.
Abstract The ongoing reclassification of higher plant genera (their division, combining and recircumscription) is the cause of extensive modifications to binomials. Many genus reclassifications have been far more taxonomically disruptive than necessary to achieve monophyletic genera.

Phylogenetic reassessment of tribe Anemoneae (Ranunculaceae): Non-monophyly of Anemone s.l. revealed by plastid datasets. [PDF]

open access: yesPLoS ONE, 2017
Morphological and molecular evidence strongly supported the monophyly of tribe Anemoneae DC.; however, phylogenetic relationships among genera of this tribe have still not been fully resolved.
