Lifespan and reproduction in Drosophila: New insights from nutritional geometry
The use of recent techniques in nutrition research to quantify the detailed relationship between diet, nutrient intake, lifespan, and reproduction in Drosophila melanogaster indicates a role for both direct costs of reproduction and other deleterious consequences of ingesting high levels of protein.
The evolution of mate choice and mating biases
It is argued that progress in understanding the evolution of mate choice is currently hampered by spurious distinctions among models and a misguided tendency to test the processes underlying each model as mutually exclusive alternatives.
Sexual selection, sexual conflict and the evolution of ageing and life span
This work synthesizes ideas and evidence linking sex and ageing, and makes the case that a focus on this fascinating problem will ultimately lead to a more complete understanding of both the evolution of ageing and the Evolution of sexual strategies.
Measuring Nonlinear Selection
It is demonstrated that the strength of non-linear selection in natural populations is low, and this finding challenges the current understanding of how selection may operate in the wild.
What is genetic quality?
Unifying and Testing Models of Sexual Selection
This work reviews evolutionary explanations for the relationship between anisogamy, potential reproductive rates, parental care, sex roles, and mate choice, and considers other forms of selection that can make females mate nonrandomly.
The sexual selection continuum
A general model of female choice for indirect benefits that captures the essence of both the ‘Fisherian’ and ‘good genes’ models is built and all versions of the model point to a single process that favours female preference for males siring offspring of high reproductive value.
High-quality male field crickets invest heavily in sexual display but die young
It is shown that nymphs and adult females reared on a high-protein diet lived longer than those on a low- protein diet, and adult males reared in this study died sooner than Those on low-protein diets because they invested more energy in calling during early adulthood.
