phytools: an R package for phylogenetic comparative biology (and other things)
  • L. Revell
  • Computer Science, Biology
  • 1 April 2012
TLDR
The focus of the phytools package is on methods for phylogenetic comparative biology; however, it also includes tools for tree inference, phylogeny input/output, plotting, manipulation and several other tasks. Expand
Size-Correction and Principal Components for Interspecific Comparative Studies

TLDR
It is shown that ignoring phylogeny in preliminary transformations can result in significantly elevated variance and type I error in the authors' statistical estimators, even if subsequent analysis of the transformed data is performed using phylogenetic methods. Expand
Phylogenetic signal and linear regression on species data
Summary 1. A common procedure in the regression analysis of interspecies data is to first test the independent and dependent variables X and Y for phylogenetic signal, and then use the presence ofExpand
Phylogenetic signal, evolutionary process, and rate.
TLDR
Individual-based numerical simulations on stochastic phylogenetic trees are used to clarify the relationship between phylogenetic signal, rate, and evolutionary process and recommend against interpretations of evolutionary process or rate based on estimates of phylogenetics signal. Expand
ECOLOGICAL OPPORTUNITY AND THE RATE OF MORPHOLOGICAL EVOLUTION IN THE DIVERSIFICATION OF GREATER ANTILLEAN ANOLES
TLDR
The results provide a complementary perspective, indicating that the rate of phenotypic diversification declines with decreasing opportunity in an adaptive radiation. Expand
Exceptional Convergence on the Macroevolutionary Landscape in Island Lizard Radiations
TLDR
For Caribbean Anolis lizards, diversification on similar Simpsonian landscapes leads to striking convergence of entire faunas on four islands, indicating that the adaptive landscape may give rise to predictable evolutionary patterns in nature, that adaptive peaks may be stable over macroevolutionary time, and that available geographic area influences the ability of lineages to discover new adaptive peaks. Expand
Two new graphical methods for mapping trait evolution on phylogenies
TLDR
Two different graphical methods for visualizing phenotypic evolution on the tree using a type of projection of the tree into morphospace called a ‘traitgram’ should prove useful in summarizing complex comparative inferences about ancestral character reconstruction. Expand
A PHYLOGENETIC TEST FOR ADAPTIVE CONVERGENCE IN ROCK-DWELLING LIZARDS
TLDR
Rock-dwelling lizards exhibited similarities in head depth as a result of both adaptation and exaptation, and the existence of similar advantageous structures among species independently occupying the same environment may not indicate adaptation. Expand
Toward a Tree-of-Life for the boas and pythons: multilocus species-level phylogeny with unprecedented taxon sampling.
TLDR
A revised taxonomy for the boas and pythons is suggested, significant evidence of discordance between taxonomy and evolutionary relationships in the genera Tropidophis, Morelia, Liasis, and Leiopython is found, and support is found for elevating two previously suggested boid species. Expand
Rapid evolution of a native species following invasion by a congener
TLDR
On small islands in Florida, it is found that the lizard Anolis carolinensis moved to higher perches following invasion by Anolis sagrei and, in response, adaptively evolved larger toepads after only 20 generations, illustrating that interspecific interactions between closely related species can drive evolutionary change on observable time scales.
