We introduce models for the runaway coevolution of female mating preferences and male display traits. The models generalize earlier results by allowing for direct natural selection on the preference, arbitrary forms of mate choice, and fairly general assumptions about the underlying genetics. Results show that a runaway is less likely when there is direct selection on the preference, but that i...

HL11 (1994) proposed that under special circumstances the models of nonadaptive (arbitrary) mate choice can be rejected on phylogenetic grounds. Specifically, in the absence of changes in female preferences or viability costs. Hill argued, the sensory exploitation (Basolo, 1990; Ryan et al., 1990) and runaway (Fisher, 1958; Lande, 1981) models provide no mechanism for reduction of a sexually se...

For a spin1 2 particle, ~ S = ~2~σ, and gs is called the Lande g-factor. From classical calculations that treat the charged particle as a rotating piece of current, gs = 1. Surprisingly, the Dirac equation in relativistic quantum mechanics predicts that gs = 2, a result which agreed with the crude experiments of the time. In the 1940’s, a new understanding of renormalization in the developing q...

C traits are constructed during development by an intricate array of factors, and interactions among factors, including DNA, RNA, proteins, developmental modules, and various aspects of the biotic and abiotic environment. As a result, it is development that structures the relationship between the genotype and phenotype and thereby determines genetic architecture. The genotype–phenotype relation...

With continually increasing global connectivity and wholesale change of landscapes, the need to understand and control the spread of invasive species has never been greater. To do so requires insight into the factors that allow particular species to become invasive to begin with as well as into the evolutionary trajectory those invasive populations follow after establishment in new ranges. One ...
