TESTING FOR PHYLOGENETIC SIGNAL IN COMPARATIVE DATA: BEHAVIORAL TRAITS ARE MORE LABILE
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. WhetherExpand

Procedures for the Analysis of Comparative Data Using Phylogenetically Independent Contrasts
We discuss and clarify several aspects of applying Felsenstein's (1985, Am. Nat. 125: 1n15) procedures to test for correlated evolution of continuous traits. This is one of several availableExpand

An Introduction to Phylogenetically Based Statistical Methods, with a New Method for Confidence Intervals on Ancestral Values
Interspecific comparisons have played a prominent role in evolutionary biology at least since the time of Charles Darwin. Since 1985, the “comparative method” has been revitalized by new analyticalExpand

Using the Past to Predict the Present: Confidence Intervals for Regression Equations in Phylogenetic Comparative Methods
Two phylogenetic comparative methods, independent contrasts and generalized least squares models, can be used to determine the statistical relationship between two or more traits. We show that theExpand

Phylogenetic Measures of Biodiversity
We developed a theoretical framework based on phylogenetic comparative methods to integrate phylogeny into three measures of biodiversity: species variability, richness, and evenness. These metricsExpand

Stability and Diversity of Ecosystems
Understanding the relationship between diversity and stability requires a knowledge of how species interact with each other and how each is affected by the environment. The relationship is alsoExpand

Morphometrics of the Avian Small Intestine Compared with That of Nonflying Mammals: A Phylogenetic Approach
Flying animals may experience a selective constraint on gut volume because the energetic cost of flight increases and maneuverability decreases with greater digesta load. The small intestine is theExpand

Methods for Detecting Early Warnings of Critical Transitions in Time Series Illustrated Using Simulated Ecological Data
Many dynamical systems, including lakes, organisms, ocean circulation patterns, or financial markets, are now thought to have tipping points where critical transitions to a contrasting state canExpand

ESTIMATING COMMUNITY STABILITY AND ECOLOGICAL INTERACTIONS FROM TIME‐SERIES DATA
Natural ecological communities are continuously buffeted by a varying environment, often making it difficult to measure the stability of communities using concepts requiring the existence of anExpand

Phylogenetic logistic regression for binary dependent variables.
We develop statistical methods for phylogenetic logistic regression in which the dependent variable is binary (0 or 1) and values are nonindependent among species, with phylogenetically relatedExpand
