This paper reviews entomophagy as practised in Africa within the context of food and
nutritional security by providing an inventory of the various species of insects that are …

Life-history traits or “fitness components”—such as age and size at maturity, fecundity and
fertility, age-specific rates of survival, and life span—are the major phenotypic determinants …

Question: Associations of body size and of body temperature with fitness have complex
relationships for ectotherms, but three general patterns are known. Bigger is better: Larger …

Understanding how natural populations will respond to rapid anthropogenic climate change
is one of the greatest challenges for ecologists and evolutionary biologists. Much research …

Founding isofemale lines from wild collected females is a basic tool for investigating the
genetic architecture of Drosophila natural populations. The method permits the analysis of …

Insects display a staggering diversity of mating and social behaviours. Studying these
systems provides insights into a wide range of evolutionary and behavioural questions, such …

Seasonal environmental heterogeneity is cyclic, persistent and geographically widespread.
In species that reproduce multiple times annually, environmental changes across seasonal …

Examples of clinal variation in phenotypes and genotypes across latitudinal transects have
served as important models for understanding how spatially varying selection and …

Gene expression variation within species is relatively common, however, the role of natural
selection in the maintenance of this variation is poorly understood. Here we investigate low …

In a broad survey of Drosophila melanogaster population samples, levels of abdominal
pigmentation were found to be highly variable and geographically differentiated. A strong …
