Abstract The primary rationale for the use of phylogenetically based statistical methods is that phylogenetic signal, the tendency for related species to resemble each other, is ubiquitous. Whether this assertion is true for a given trait in a given lineage is an empirical question, but general tools for detecting and quantifying phylogenetic signal are inadequately developed. We present new methods for continuous-valued characters that can be implemented with either phylogenetically… Expand

Rapidly evolving traits and the comparative method: how important is testing for phylogenetic signal?
TLDR
It is shown that the bird song parameters investigated are not correlated to their phylogenetic history, indicating that certain aspects of bird song can be subject to rates of evolution that are much more rapid than speciation events. Expand
Evolutionary Models and Phylogenetic Signal Assessment via Mantel Test
TLDR
A new analytical procedure is described, which incorporates explicitly an evolutionary model in the standard Mantel test (EM-Mantel), which is a good alternative for measuring phylogenetic signal in binary and categorical traits and for datasets with multiple traits. Expand
TESTING FOR PHYLOGENETIC SIGNAL IN BIOLOGICAL TRAITS: THE UBIQUITY OF CROSS‐PRODUCT STATISTICS
To evaluate rates of evolution, to establish tests of correlation between two traits, or to investigate to what degree the phylogeny of a species assemblage is predictive of a trait value so‐called… Expand
A comparison of metrics for estimating phylogenetic signal under alternative evolutionary models
TLDR
It is shown that statistical approaches provide valid results and may be still particularly useful when detailed phylogenies are unavailable or when trait variation among species is difficult to describe by more standard Brownian or O-U evolutionary models. Expand
Is your phylogeny informative? Measuring the power of comparative methods
TLDR
It is concluded that researchers should not assume a model such as Brownian motion a priori but test alternate hypotheses; not test for correlations between traits and branch lengths before applying a phylogenetic model but rather analyze the power of the tree to identify the chosen model from the alternative hypotheses. Expand
Testing and quantifying phylogenetic signals and homoplasy in morphometric data.
TLDR
A test for the presence of a phylogenetic signal in morphometric data is proposed, which simulates the null hypothesis of the complete absence of phylogenetic structure by permutation of the shape data among the terminal taxa. Expand
How to measure and test phylogenetic signal
TLDR
These guidelines aim to better assess phylogenetic signal and distinguish it from random trait distributions and are developed under the assumption of BM, and additional simulations with more complex trait evolution models show that they are to a certain degree generalizable. Expand
Testing for phylogenetic signal in phenotypic traits: new matrices of phylogenetic proximities.
TLDR
This work provides the exact analytic value of this test, revealing that it uses Moran's I statistic with a new matrix of phylogenetic proximities that enhances the power of Moran's test and is useful for unresolved trees. Expand
A METHOD FOR ASSESSING PHYLOGENETIC LEAST SQUARES MODELS FOR SHAPE AND OTHER HIGH‐DIMENSIONAL MULTIVARIATE DATA
  • D. Adams
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2014
TLDR
The new procedure provides a useful means of assessing trait covariation across a set of taxa related by a phylogeny, enabling macroevolutionary biologists to test hypotheses of adaptation, and phenotypic change in high‐dimensional datasets. Expand
Integrating spatial and phylogenetic information in the fourth-corner analysis to test trait-environment relationships.
TLDR
This work demonstrates how the presence of spatial and phylogenetic autocorrelations can, in some circumstances, lead to inflated type I error rates, suggesting that significant associations can be misidentified and proposes a new randomization approach designed to avoid this issue. Expand

Procedures for the Analysis of Comparative Data Using Phylogenetically Independent Contrasts
TLDR
Any (continuous) trait that is inherited from ancestors is appropriate for analysis, regardless of the mechanism of inheritance (e.g., genetic or cultural), according to Felsenstein's method. Expand
Phylogenetic Analysis and Comparative Data: A Test and Review of Evidence
TLDR
Simulations show λ to be a statistically powerful index for measuring whether data exhibit phylogenetic dependence or not and whether it has low rates of Type I error, which demonstrates that even partial information on phylogeny will improve the accuracy of phylogenetic analyses. Expand
An Introduction to Phylogenetically Based Statistical Methods, with a New Method for Confidence Intervals on Ancestral Values
TLDR
Three phylogenetically based statistical methods are presented, including phylogenetically independent contrasts, Monte Carlo computer simulations to obtain null distributions of test statistics, and phylogenetic autocorrelation, which allow traditional topics in comparative and ecological physiology to be addressed with greater rigor.

A Generalized Permutation Model for the Analysis of Cross-Species Data
TLDR
It is shown that the conventional, equally likely (EL) randomization model is a special case of the phylogenetic permutations (PP), and an application of the method is presented to test the correlation between two traits with cross-species data. Expand
TESTING HYPOTHESES OF CORRELATED EVOLUTION USING PHYLOGENETICALLY INDEPENDENT CONTRASTS: SENSITIVITY TO DEVIATIONS FROM BROWNIAN MOTION
We examined the statistical performance (in terms of type I error rates) of Felsenstein's (1985, Am. Nat. 125:1-15) comparative method of phylogenetically independent contrasts for test- ing… Expand
Adaptation: Statistics and a Null Model for Estimating Phylogenetic Effects
TLDR
Statistics and a null model for estimating phylogenetic effects in comparative data are proposed and a model-independent measure of autocorrelation (Moran's I) is applied for estimating whether cross-taxonomic trait variation is related to phylogeny. Expand
METHODS FOR THE ANALYSIS OF COMPARATIVE DATA IN EVOLUTIONARY BIOLOGY
  • M. Lynch
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1991
TLDR
Methods are presented for the estimation of phylogenywide means of characters, the variance‐covariance structure of the components of taxon‐specific means, and the mean phenotypes of ancestral taxa and it is argued that the covarianceructure of phylogenetic effects provides a description of a macroevolutionary pattern. Expand
Truth or Consequences: Effects of Phylogenetic Accuracy on Two Comparative Methods
TLDR
Simulations show independent contrasts to be valid when branch lengths are known, whether or not the topology is known fully, and how the two approaches stand up to incompletely resolved trees and incorrect branch length information—common situations for comparative biologists. Expand

TLDR
The simulations showed that random samples, with respect to the traits under consideration, provide statistically robust estimates of trait correlations, but exact significance tests are highly dependent on appropriate branch length information; equal branch lengths maintain lower Type I error than alternative topological approaches, and adjusted critical values of the independent contrast correlation coefficient are provided.
