Phylogenetic signal and potential for invasiveness
Agricultural and Forest Entomology, 2016Abstract We hypothesized that the evolutionary stability of insect traits relevant to invasion risk can be used to characterize this risk and the confidence in assigning potential invasiveness ...

Significant phylogenetic signal is not enough to trust phylogenetic predictions
2022AbstractIn a recent study, Cantwell-Jones et al. (2022) proposed a list of 1044 species as promising key sources of B vitamins based primarily on phylogenetic predictions. To identify candidate plants, they fitted lambda models of evolution to edible species with known values in each of six B vitamins (232 to 280 species) and used the estimated ...

Phylogenetic Methods to Study Light Signaling
2019Phylogenetic comparative methods (PCM) represent a rigorous approach for inferring functional evolution. To infer the origin and evolution of a function, PCM use a phylogenetic tree of the species in which the function has evolved and functional data from those species.

International Journal of Parasitology, 2018
Parasites can vary in the number of host species they infect, a trait known as "host specificity". Here we quantify phylogenetic signal-the tendency for closely related species to resemble each other more than distantly related species-in host ...

Phylogenetic comparison of oskar mRNA localization signals
Biochemical and Biophysical Research Communications, 2014As a way to spatially control the expression of genes within cells, RNA localization is being recognized as an important process by which proteins are restricted to specific subcellular domains, which occurs in more diverse types of tissue than previously considered.

Testing for phylogenetic signal in phenotypic traits: New matrices of phylogenetic proximities
Theoretical Population Biology, 2008Abouheif adapted a test for serial independence to detect a phylogenetic signal in phenotypic traits. We provide the exact analytic value of this test, revealing that it uses Moran's I statistic with a new matrix of phylogenetic proximities. We introduce then two new matrices of phylogenetic proximities highlighting their mathematical properties ...

Phylogenomic methods can be used to investigate the tangled evolutionary relationships among genomes. Building 'all the trees of all the genes' can potentially identify common pathways of horizontal gene transfer (HGT) among taxa at varying levels of phylogenetic depth.

Is There a Phylogenetic Signal in Prokaryote Proteins?
Journal of Molecular Evolution, 1999Using the sequence information from nine completely sequenced bacterial genomes, we extract 32 protein families that are thought to contain orthologous proteins from each genome. The alignments of these 32 families are used to construct a phylogeny with the neighbor-joining algorithm.

Comparative Methods and Phylogenetic Signal
2013The objectives of this chapter are to consider trait data in the context of phylogenetic information. We will begin by discussing how to quantify the relationships between the traits of species while accounting for the nonindependence of species.
