The mistreatment of covariate interaction terms in linear model analyses of behavioural and evolutionary ecology studies
In behavioural and evolutionary ecology, there are often large phenotypic differences between individuals in, for example, body size or large variation in abiotic conditions such as temperature,Expand

Pitfalls in experiments testing predictions from sperm competition theory
As females of many species mate with more than one male, ejaculates often face competition from the sperm of other males. In recent years, numerous papers have been published on theoreticalExpand

Theoretical influence of female mating status and remating propensity on male sperm allocation patterns
Theoretical models predict that males should allocate more sperm in matings where the immediate risk of sperm competition is high. It has therefore often been argued that males should invest lessExpand

Cryptic male choice: sperm allocation strategies when female quality varies
We examined evolutionary stable sperm allocation and included stochastic variation in male mating frequency, not included in previous models examining sperm allocation strategies. We assumed spermExpand

Meta-analysis of variation: ecological and evolutionary applications and beyond
Summary 1. Meta-analysis has become a standard way of summarizing empirical studies in many fields, including ecology and evolution. In ecology and evolution, meta-analyses comparing two groupsExpand

THE VARIABILITY IS IN THE SEX CHROMOSOMES
Sex differences in the mean trait expression are well documented, not only for traits that are directly associated with reproduction. Less is known about how the variability of traits differs betweenExpand

Nuptial gift consumption influences female remating in a scorpionfly: male or female control of mating rate?
In the scorpionfly Panorpa cognata, males provide females with saliva secretions as nuptial food gifts. Consequently, females derive material benefits and possibly also genetic benefits from multipleExpand

In animal species with high male mating effort, males often find themselves in a dilemma: by increasing their mating effort, the gain from each copulation increases but simultaneously reducesExpand

Male attractiveness is negatively genetically associated with investment in copulations
In species with high male mating effort, there is a trade-off between mating effort spent in a current mating and resources left for future matings. Males are therefore expected to allocate resourcesExpand

Costly plastic morphological responses to predator specific odour cues in three-spined sticklebacks (Gasterosteus aculeatus)
Predation risk is one of the major forces affecting phenotypic variation among and within animal populations. While fixed anti-predator morphologies are favoured when predation level is consistentlyExpand
