Mitochondrial genomes of yeasts of the Yarrowia clade [PDF]

open access: yesFEMS Yeast Research, 2012
Candida alimentaria, Candida deformans, Candida galli, and Candida phangngensis have been recently reported to be the close relatives of Yarrowia lipolytica. To explore this clade of yeasts, we sequenced the mitochondrial genome (mtDNA) of these four species and compared it with the mtDNA of Y. lipolytica. The five mtDNAs exhibit a similar architecture

Phylogenomics, historical biogeography, and diversification of leaf traits in the Malagasy‐endemic genus Uncarina (Pedaliaceae)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Uncarina contains 14 species of woody plants endemic to Madagascar. Its occurrence across dryland biomes on the island make it an interesting system to study the diversification of the flora. Methods Using samples of all species and 512 nuclear loci, we reconstructed phylogenetic trees to examine species relationships and assess their ...

Clades, clans and reciprocal monophyly under neutral evolutionary models [PDF]

open access: yesarXiv, 2011
The Yule model and the coalescent model are two neutral stochastic models for generating trees in phylogenetics and population genetics, respectively. Although these models are quite different, they lead to identical distributions concerning the probability that pre-specified groups of taxa form monophyletic groups (clades) in the tree.

Unique clade of alphaproteobacterial endosymbionts induces complete cytoplasmic incompatibility in the coconut beetle

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2017
Significance Maternally inherited bacterial endosymbionts in arthropods manipulate host reproduction to increase the number of infected females. Cytoplasmic incompatibility (CI) is one such manipulation, in which infected females can produce offspring by

The Molecular Phylogenetic Signature of Clades in Decline

open access: yesPLoS ONE, 2011
Molecular phylogenies have been used to study the diversification of many clades. However, current methods for inferring diversification dynamics from molecular phylogenies ignore the possibility that clades may be decreasing in diversity, despite the fact that the fossil record shows this to be the case for many groups.

New Insights Into the Plastome Evolution of the Millettioid/Phaseoloid Clade (Papilionoideae, Leguminosae)

open access: yesFrontiers in Plant Science, 2020
The Millettioid/Phaseoloid (MP) clade from the subfamily Papilionoideae (Leguminosae) consists of six tribes and ca. 3,000 species. Previous studies have revealed some plastome structural variations (PSVs) within this clade.

Maximal clades in random binary search trees [PDF]

open access: yesarXiv, 2014
We study maximal clades in random phylogenetic trees with the Yule-Harding model or, equivalently, in binary search trees. We use probabilistic methods to reprove and extend earlier results on moment asymptotics and asymptotic normality. In particular, we give an explanation of the curious phenomenon observed by Drmota, Fuchs and Lee (2014) that ...

Dynamics of clade diversification on the morphological hypercube [PDF]

open access: yesarXiv, 1998
Understanding the relationship between taxonomic and morphological changes is important in identifying the reasons for accelerated morphological diversification early in the history of animal phyla. Here, a simple general model describing the joint dynamics of taxonomic diversity and morphological disparity is presented and applied to the data on the ...

Making the Most of Clade Selection

open access: yesPhilosophia Scientiæ, 2017
Clade selection is unpopular with philosophers who otherwise accept multilevel selection theory. Clades cannot reproduce, and reproduction is widely thought necessary for evolution by natural selection, especially of complex adaptations.

Emergence of a New Highly Successful Acapsular Group A Streptococcus Clade of Genotype emm89 in the United Kingdom

open access: yesmBio, 2015
Group A Streptococcus (GAS) genotype emm89 is increasingly recognized as a leading cause of disease worldwide, yet factors that underlie the success of this emm type are unknown.
