Colour Morphs as Alternative Solutions to the Trade‐Off Predicted by the Immuno‐Competence Handicap Hypothesis

open access: yesIntegrative Zoology, EarlyView.
In this study, we tested whether white and yellow morphs of the common wall lizard (Podarcis muralis) adopt alternative strategies shaped by the immuno‐competence handicap hypotheses (ICHH). We found that testosterone‐induced immune suppression was stronger in white males, while aggression decreased in both morphs.

Consequently, empirical evidence on how cooperative membership shapes farmers’ commercialization across ...

A Bayes factor framework for unified parameter estimation and hypothesis testing

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The Bayes factor, the data‐based updating factor of the prior to posterior odds of two hypotheses, is a natural measure of statistical evidence for one hypothesis over the other. We show how Bayes factors can also be used for parameter estimation.
