Detecting taxonomic and phylogenetic signals in equid cheek teeth: towards new palaeontological and archaeological proxies [PDF]

open access: yesRoyal Society Open Science, 2017
The Plio–Pleistocene evolution of Equus and the subsequent domestication of horses and donkeys remains poorly understood, due to the lack of phenotypic markers capable of tracing this evolutionary process in the palaeontological/archaeological record ...

Phylogenetic Signal of Indels and the Neoavian Radiation

open access: yesDiversity, 2019
The early radiation of Neoaves has been hypothesized to be an intractable “hard polytomy”. We explore the fundamental properties of insertion/deletion alleles (indels), an under-utilized form of genomic data with the potential to help solve this.

Plasmodium vivax-like genome sequences shed new insights into Plasmodium vivax biology and evolution [PDF]

open access: yes, 2018
Although Plasmodium vivax is responsible for the majority of malaria infections outside Africa, little is known about its evolution and pathway to humans. Its closest genetic relative, P.

Phylogenetic and functional signals in gymnosperm ovular secretions [PDF]

open access: yesAnnals of Botany, 2017
Gymnosperms are either wind-pollinated (anemophilous) or both wind- and insect-pollinated (ambophilous). Regardless of pollination mode, ovular secretions play a key role in pollen capture, germination and growth; they are likely also involved in pollinator reward. Little is known about the broad-scale diversity of ovular secretions across gymnosperms,

Whole Genome Phylogenetic Tree Reconstruction Using Colored de Bruijn Graphs

open access: yes, 2017
We present kleuren, a novel assembly-free method to reconstruct phylogenetic trees using the Colored de Bruijn Graph. kleuren works by constructing the Colored de Bruijn Graph and then traversing it, finding bubble structures in the graph that provide ...

Decreased cold‐sensing function of the transient receptor potential channel TRPM8 from tailed amphibians

open access: yesFEBS Open Bio, EarlyView.
Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.
