Why do females mate multiply? A review of the genetic benefits

    Biological reviews of the Cambridge Philosophical…
  • 1 February 2000
TLDR
It is concluded that post‐copulatory mechanisms provide a more reliable way of selecting a genetically compatible mate than pre-copulatory mate choice and that some of the best evidence for cryptic female choice by sperm selection is due to selection of more compatible sperm.
VARIATION IN MATE CHOICE AND MATING PREFERENCES: A REVIEW OF CAUSES AND CONSEQUENCES
TLDR
It is concluded that sexual‐selection studies have paid far less attention to variation among females than to variations among males, and that there is still much to learn about how females choose males and why different females make different choices.
How much variance can be explained by ecologists and evolutionary biologists?
TLDR
A meta-analysis using data from 43 published meta-analyses in ecology and evolution with 93 estimates of mean effect size using Pearson's r and 136 estimates using Hedges' d or g revealed that the mean amount of variance (r2) explained was 2.51–5.42%.
Parental investment, sexual selection and sex ratios
TLDR
An integrative model shows how factors interact to generate sex roles and underscores the need to distinguish between the ASR and the operational sex ratio (OSR) if mortality is higher when caring than competing this diminishes the likelihood of sex role divergence.
The evolution of mate choice and mating biases
TLDR
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.
Do invasive species show higher phenotypic plasticity than native species and, if so, is it adaptive? A meta-analysis.
TLDR
The finding that invasive species are more plastic in a variety of traits but that non-invasive species respond just as well, if not better, when resources are limiting, has interesting implications for predicting responses to global change.
What is genetic quality?
TLDR
It is argued that genetic quality is the breeding value of an individual for total fitness, drawing on concepts from life-history theory and quantitative genetics, and how approaches incorporating these insights might result in empirical progress.
The Extent and Consequences of P-Hacking in Science
TLDR
It is suggested that p-hacking probably does not drastically alter scientific consensuses drawn from meta-analyses, and its effect seems to be weak relative to the real effect sizes being measured.
Unifying and Testing Models of Sexual Selection
TLDR
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.
High-quality male field crickets invest heavily in sexual display but die young
TLDR
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.
