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...

Ecological research in the past few decades has shown that most animals acquire and respond adaptively to information that affects survival and reproduction. At the same time, neurobiological studies have established that the rate of information processing by the brain is much lower than the rate at which information is encountered in the environment, and that attentional mechanisms enable the ...

are displayed prominently in intraspecific interactions, such as aggressive or mating behavior. These animals thus use patterns of polarized light in the same way that other species use color patterns, providing a unique and therefore unmistakable appearance to visual systems capable of analyzing polarization patterns. Also, since the polarization pattern is independent of the spectrum of illum...

Controlling postharvest pest species is a costly process with insecticide resistance and species-specific control requiring multiple tactics. Mating disruption (MD) can be used to both decrease a female's access to males and delay timing of mating and decreases overall mating success in a population and population growth rate. Development of new commercially available MD products requires an un...

We examine the relationship between controlled and uncontrolled visual preference tests. We compare the results for the preference of printed images in various viewing environments. The data are examined with regard to different numbers of observer subsets and we can derive an experimental guideline for an equivalence of the controlled and uncontrolled preference experiments based on the certai...
