Fitting generalised linear models (GLMs) with more than one predictor has become the standard
method of analysis in evolutionary and behavioural research. Often, GLMs are used for …

Mixed-effect models are frequently used to control for the nonindependence of data points,
for example, when repeated measures from the same individuals are available. The aim of …

Recently there has been a growing concern that many published research findings do not
hold up in attempts to replicate them. We argue that this problem may originate from a culture …

When data are not normally distributed, researchers are often uncertain whether it is legitimate
to use tests that assume Gaussian errors, or whether one has to either model a more …

Context-dependent biological variation presents a unique challenge to the reproducibility of
results in experimental animal research, because organisms’ responses to experimental …

Meiotic drivers are genetic variants that selfishly manipulate the production of gametes to
increase their own rate of transmission, often to the detriment of the rest of the genome and the …

Birds selecting a nest site have to find the best compromise between the risk of encountering
predation, the availability of food near to the nest and microclimatic requirements. As the …

Understanding the causes and consequences of variation in the rate of recombination is
essential since this parameter is considered to affect levels of genetic variability, the efficacy of …

Although elaborate bird song provides one of the prime examples of a trait that evolved under
sexual selection, it is still unclear whether females judge the quality of males by attributes …

Why do females of so many socially monogamous species regularly engage in matings
outside the pair bond? This question has puzzled behavioural ecologists for more than two …
