THE MEASUREMENT OF SELECTION ON CORRELATED CHARACTERS

Measures of directional and stabilizing selection on each of a set of phenotypically correlated characters are derived, retrospective, based on observed changes in the multivariate distribution of characters within a generation, not on the evolutionary response to selection.

Morphology, Performance and Fitness

The problem of measuring selection on morphological traits is simplified by breaking the task into two parts: measurement of the effects of morphological variation on performance and measurement ofThe effects of performance on fitness.

ON THE MEASUREMENT OF NATURAL AND SEXUAL SELECTION: THEORY

An approach to the empirical measurement of selection that is directly related to formal evolutionary theory is illustrated and a mode of data analysis that describes selection in useful, theoretical terms is presented so that field or experimental results will have a tangible relationship to equations for evolutionary change.

HIERARCHICAL COMPARISON OF GENETIC VARIANCE‐COVARIANCE MATRICES. I. USING THE FLURY HIERARCHY

Flury (1988) has provided an approach to matrix comparison in which a variety of hypotheses are tested, including the two extreme hypotheses prevalent in the evolutionary literature, which are adapted to the problem of comparing G‐matrices by using randomization testing to account for nonindependence induced by family structure.

VISUALIZING MULTIVARIATE SELECTION

It is concluded that selection may be more usefully classified into two general modes, directional and non linear selection, with stabilizing and disruptive selection as special cases of nonlinear selection.

Animal Mating Systems: A Synthesis Based on Selection Theory

It is argued that sexual selection gradients are the key to understanding how the intensity of sexual selection is affected by mate provisioning, parental investment, and sex ratio.

Understanding The Evolution And Stability Of The G-Matrix

Simulation studies of evolving G-matrices offer solutions to some of the problems of stability and evolution of the G-Matrix, as well as a deeper, synthetic understanding of both theG-matrix and adaptive radiations.

ON THE MEASUREMENT OF NATURAL AND SEXUAL SELECTION: APPLICATIONS

This paper uses measures of selection developed by quantitative geneticists and some new results to analyze multiple episodes of selection in natural populations of amphibians, reptiles, and insects.

Hot Rocks and Not-So-Hot Rocks: Retreat-Site Selection by Garter Snakes and Its Thermal Consequences

Studies of behavioral thermoregulation ofectotherms have typically focused only on active animals. However, most temperate-zone ectotherms actually spend more time sequestered in retreats (e.g.,…
