Chilling out or heating up? Thermal plasticity of seminal fluid proteins in <i>Drosophila melanogaster</i> Open
Seminal fluid proteins (SFPs) play crucial roles in reproduction by shaping female post-mating physiology and behaviour, male sperm competition, and sexual conflict between the sexes. We mostly ignore how abiotic ecological factors regulat…

The Developmental Environment Mediates Adult Seminal Proteome Allocation in Male <i>Drosophila melanogaster</i> Open
Early life conditions can have long‐lasting effects on fitness. In insects, larval crowding increases intraspecific competition, shaping adult phenotypes and influencing male reproductive success in pre‐ and post‐mating competition. Althou…

Short-term increases in rival number improves single mating productivity in male <i>Drosophila</i> Open
In variable environments, animals can change their reproductive behaviors and physiology to maximize reproductive returns. Natural environments vary in multifaceted ways, and animals may need to integrate multiple social or physical cues t…

A male-biased sex ratio increases the opportunity for precopulatory sexual selection but does not change the Bateman gradient Open
Theory predicts that the sex ratio within populations should influence the strength of sexual selection, and sex ratio is often used as a proxy for sexual selection. However, recent studies challenge this relationship. We manipulated adult…

Sterol deprivation elicits a somatic cost exclusively towards Drosophila melanogaster males that are reproductively-active Open
The extension of lifespan via the restriction of nutrients (dietary restriction) remains a poorly-understood phenomenon both within the context of life-history theory, and at a mechanistic level, despite presenting as an ideal opportunity …

Sterol deprivation elicits a somatic cost exclusively towards Drosophila melanogaster males that are reproductively-active Open
The effect of nutrition on life-history has received considerable attention from evolutionary theory and mechanistic studies, particularly in relation to the ability of dietary restriction to extend lifespan. A body of evidence has formed,…

The developmental environment mediates adult seminal proteome allocation in male <i>Drosophila melanogaster</i> Open
Early life conditions can have long-lasting fitness effects on organisms. In insects, crowding during larval stages impose a significant constraint on adult phenotypes due to increased intraspecific competition for resources, which can mod…

Social group composition modulates the role of last male sperm precedence in post-copulatory sexual selection Open
In many species, the order in which males mate with a female explains much of the variation in paternity arising from post-copulatory sexual selection. Research in Drosophila suggests that mating order may account for the majority of the v…

Timeless or tainted? The effects of male ageing on seminal fluid Open
Reproductive ageing can occur due to the deterioration of both the soma and germline. In males, it has mostly been studied with respect to age-related changes in sperm. However, the somatic component of the ejaculate, seminal fluid, is als…

Ecological lipidology Open
Dietary lipids (DLs), particularly sterols and fatty acids, are precursors for endogenous lipids that, unusually for macronutrients, shape cellular and organismal function long after ingestion. These functions – cell membrane structure, in…

On how to identify a seminal fluid protein: A commentary on Hurtado et al. Open
Seminal fluid proteins (Sfps) have striking effects on the behaviour and physiology of females in many insects. Some Drosophila melanogaster Sfps are not highly or exclusively expressed in the accessory glands, but derive from, or are addi…

Experimental evolution under varying sex ratio and nutrient availability modulates male mating success in <i>Drosophila melanogaster</i> Open
Biased population sex ratios can alter optimal male mating strategies, and allocation to reproductive traits depends on nutrient availability. However, there is little information on how nutrition interacts with sex ratio to influence the …

Relatedness modulates density‐dependent cannibalism rates in <i>Drosophila</i> Open
Cannibalism is taxonomically widespread and can have large impacts on individual fitness and population‐level processes. As such, identifying how cannibalism rates vary in response to ecological cues is important for predicting species evo…

‘Hangry’ Drosophila: food deprivation increases male aggression Open
Aggressive interactions are costly, such that individuals should display modified aggression in response to environmental stress. Many organisms experience frequent periods of food deprivation, which can influence an individual's capacity …

Male condition influences female post mating aggression and feeding in <i>Drosophila</i> Open
Mating changes female behaviour and physiology across a wide range of taxa, with important effects for male and female fitness. These changes are often induced by components of the male ejaculate, such as sperm and seminal fluid proteins. …

Sex ratio and the evolution of aggression in fruit flies Open
Aggressive behaviours are among the most striking displayed by animals, and aggression strongly impacts fitness in many species. Aggression varies plastically in response to the social environment, but we lack direct tests of how aggressio…
