TESTING FOR PHYLOGENETIC SIGNAL IN COMPARATIVE DATA: BEHAVIORAL TRAITS ARE MORE LABILE
TLDR
Analysis of variance of log K for all 121 traits indicated that behavioral traits exhibit lower signal than body size, morphological, life-history, or physiological traits, and this work presents new methods for continuous-valued characters that can be implemented with either phylogenetically independent contrasts or generalized least-squares models.
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.
Phylogenetic Analysis of Covariance by Computer Simulation
TLDR
Using empirically scaled computer simulation models of continuous traits evolving along phylogenetic trees to obtain null distributions of F statistics for ANCOVA of comparative data sets is proposed.
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.
Why tropical forest lizards are vulnerable to climate warming
TLDR
Focal species analyses show that some tropical forest lizards were already experiencing stressful body temperatures in summer when studied several decades ago, and simulations suggest that warming will not only further depress their physiological performance in summer, but will also enable warm-adapted, open-habitat competitors and predators to invade forests.
The primate semicircular canal system and locomotion
TLDR
Quantitative phylogenetically informed analysis of the radius of curvature of the three semicircular canals in 91 extant and recently extinct primate species and 119 other mammalian taxa provide support for the hypothesis that canal size varies in relation to the jerkiness of head motion during locomotion.
EVOLUTION OF SPRINT SPEED IN LACERTID LIZARDS: MORPHOLOGICAL, PHYSIOLOGICAL, AND BEHAVIORAL COVARIATION
TLDR
Among the 13 species or subspecies of lizards in the present study, differences in the optimal temperature for sprinting closely matched interspecific variation in median preferred body temperature, indicating correlated evolution of thermal physiology and thermal preferences.
Mouse inbred strain differences in ethanol drinking to intoxication
TLDR
Strain mean correlations with other traits in the Mouse Phenome Project database supported previously reported genetic relationships of high ethanol drinking with low chronic ethanol withdrawal severity and low ethanol‐conditioned taste aversion.
Artificial Selection for Increased Wheel-Running Behavior in House Mice
TLDR
Replicated within-family selection for increased voluntary wheel running in outbred house mice (Mus domesticus) was applied with four high-selected and four control lines (10 families/line) and resulted in an average 75% increase in activity in the four selected lines, as compared with control lines.
PHYLOGENETIC ANALYSES OF THE CORRELATED EVOLUTION OF CONTINUOUS CHARACTERS: A SIMULATION STUDY
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
