Fungi evolution revisited: Application of the penalized likelihood method to a bayesian fungal phylogeny provides a new perspective on phylogenetic relationships and divergence dates of ascomycota groups
(Springer, 2005-06-01)
The depiction of evolutionary relationships within phylum Ascomycota is still controversial because of unresolved branching orders in the radiation of major taxa. Here we generated a dataset of 166 small subunit (18S) rDNA ...
Green Web or megabiased clock? Plant fossils from Gondwanan Patagonia speak on evolutionary radiations
(Wiley, 2015-07)
Evolutionary divergence-age estimates derived from molecular ‘clocks’ are frequently correlated with paleogeographic, paleoclimatic and extinction events. One prominent hypothesis based on molecular data states that the ...
Ecological divergence and synchronous Pleistocene diversification in the widespread South American butter frog complex
(2022-04-01)
Phylogeographic studies primarily focus on the major role of landscape topography in driving lineage diversification. However, populational phylogeographic breaks may also occur as a result of either niche conservatism or ...
Molecular dating and diversification of the South American lizard genus Liolaemus (subgenus Eulaemus) based on nuclear and mitochondrial DNA sequences
(Oxford University Press, 2012-04)
The temperate South American lizard genus Liolaemus is the one of the most widely distributed and species-rich genera of lizards on earth. The genus is divided into two subgenera, Liolaemus sensu stricto (the 'Chilean ...
Incorporating phylogenetic uncertainty on phylogeny-based palaeontological dating and the timing of turtle diversification
(Wiley, 2012-09-10)
Methods improving the performance of molecular dating of divergence time of clades have improved dramatically in recent years. The calibration of molecular dating using the first appearance of a clade in the fossil record ...
Phylogeny and evolutionary patterns of South American octodontoid rodents
(Polish Academy of Sciences. Institute of Paleobiology, 2013-03)
Octodontoidea is the most diverse clade of hystricognath rodents, and is richly recorded in South America since at least the Oligocene. A parsimony-based morphological phylogenetic analysis of a wide range of extant and ...
Origin and diversification of Xanthomonas citri subsp. citri pathotypes revealed by inclusive phylogenomic, dating, and biogeographic analyses
(2019-09-09)
Background: Xanthomonas citri subsp. citri pathotypes cause bacterial citrus canker, being responsible for severe agricultural losses worldwide. The A pathotype has a broad host spectrum, while A∗and Aw are more restricted ...
Phylogeny and divergence times of suckers (Cypriniformes: Catostomidae) inferred from Bayesian total-evidence analyses of molecules, morphology, and fossils
(Peerj Inc, 2018-07-04)
Catostomidae (suckers) is a diverse (76 species) and broadly distributed family of Holarctic freshwater fishes with a rich fossil record and a considerable number (similar to 35%) of threatened and imperiled species. We ...
