Many fields of biology employ cross-species comparisons. However, because species descend with modification from common ancestors, and rates of evolution may vary among branches of an evolutionary tree, problems of nonindependence and nonidentical distributions may occur in comparative data sets. Several phylogenetically based statistical methods have been developed to deal with these issues, but two are most commonly used. Independent contrasts attempts to transform the data to meet the i.i.d… 

Evolutionary Models and Phylogenetic Signal Assessment via Mantel Test

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.

Permutation tests for comparative data

Two new non-parametric constructs for the analysis of a broader range of comparative questions are introduced: phylogenetic permutation tests, based on cyclic permutations and permutations conserving phylogenetic signal.

Canonical phylogenetic ordination.

Results showed that the new technique detected previously overlooked variation clearly associated with phylogeny and that many phylogenetic effects on comparative data may occur at particular groups rather than across the entire tree.

Phylogenetic approaches in comparative physiology

It is the personal opinion that the incorporation of phylogeny information into comparative studies has been highly beneficial, not only because it can improve the reliability of statistical inferences, but also because it continually emphasizes the potential importance of past evolutionary history in determining current form and function.

General quantitative genetic methods for comparative biology: phylogenies, taxonomies and multi‐trait models for continuous and categorical characters

This paper takes three recent publications that develop phylogenetic meta‐analysis, either implicitly or explicitly, and shows how they can be considered as quantitative genetic models and highlights some of the difficulties with the proposed solutions, and demonstrates that standard quantitative genetic theory and software offer solutions.

An assessment of phylogenetic tools for analyzing the interplay between interspecific interactions and phenotypic evolution

It is found that currently used statistical methods largely fail to detect the impact of interspecific interactions on trait evolution, that sister taxa analyses often erroneously detect character displacement where it does not exist, and that recently developed process-based models have more satisfactory statistical properties.

Phylogenetic logistic regression for binary dependent variables.

Analysis of statistical methods for phylogenetic logistic regression in which the dependent variable is binary (0 or 1) and values are nonindependent among species, with phylogenetically related species tending to have the same value of the dependent variables shows that, as with the case for continuous-valued dependent variables, this method should be used when there is the possibility of phylogenetic correlations among species.

It is found that the Mantel test has poor performance compared to alternative methods, including low power and, under some circumstances, inflated type‐I error, and should be restricted to cases in which data can only be expressed as pairwise distances among taxa.

Conservation and Convergence of Genetic Architecture in the Adaptive Radiation of Anolis Lizards

It is found that the overall structure of G does not converge, but several elements of G showed signatures of convergence, indicating that some aspects of genetic architecture have been shaped by selection.

THE PHYLOGENY OF A SPECIES-LEVEL TENDENCY: SPECIES HERITABILITY AND POSSIBLE DEEP ORIGINS OF BERGMANN'S RULE IN TETRAPODS

One of the most widely recognized generalizations in biology is Bergmann’s rule, the observation that, within species of birds and mammals, body size tends to be inversely related to ambient

An Introduction to Phylogenetically Based Statistical Methods, with a New Method for Confidence Intervals on Ancestral Values

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.

Phylogenies and the Comparative Method

A method of correcting for the phylogeny has been proposed, which specifies a set of contrasts among species, contrasts that are statistically independent and can be used in regression or correlation studies.

Procedures for the Analysis of Comparative Data Using Phylogenetically Independent Contrasts

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.

We use computer simulation to compare the statistical properties of several methods that have been proposed for estimating the evolutionary correlation between two continuous traits, and define

Phylogenies and the Comparative Method: A General Approach to Incorporating Phylogenetic Information into the Analysis of Interspecific Data

A generalized linear model (GLM) is presented for the analysis of comparative data, which can be used to address questions regarding the relationship between traits or between traits and environments, the rate of phenotypic evolution, the degree of phylogenetic effect, and the ancestral state of a character.

One conclusion is that the dates of splits between taxa, even supplemented by rates of neutral gene evolution, do not provide the ‘ true ’ covariance structure, and a pragmatic approach is adopted.

Comparative statistical techniques are able to recover the historical trends of evolution, that is, the ways in which evolution has proceeded along the branches of the phylogenetic tree, from analysis of the variation among the contemporary species of a phylogeny.

RESAMPLING METHODS FOR COMPUTATION-INTENSIVE DATA ANALYSIS IN ECOLOGY AND EVOLUTION

This review focuses on four related techniques known in the statistical and biological literature as randomization (or permutation) tests, Monte Carlo methods, bootstrapping, and the jackknife, and concludes that resampling methods are well represented in ecology and evolution.

A computer program is presented, Fels-Rand, that performs random trees from the known phylogeny that are fully-resolved but consistent with the known tree, and the usefulness of Xlisp-Stat as a system for phylogenetic computation is discussed.
