The distinct reproductive roles of males and females, which for many years were
characterised in terms of competitive males and choosy females, have remained a central …

Interest in Drosophila courtship behavior has a long-standing tradition, starting with the
works by Sturtevant in 1915, and by Bastock and Manning in the 50s. The neural and …

Males from many species ensure paternity by preventing their mates from copulating with
other males. One mate-guarding strategy involves marking females with anti-aphrodisiac …

We determined female genome sizes using flow cytometry for 211 Drosophila melanogaster
sequenced inbred strains from the Drosophila Genetic Reference Panel, and found …

In Drosophila, the male sex pheromone cis-vaccenyl acetate (cVA) elicits aggregation and
courtship, through the odorant receptor Or67d. Long-lasting exposure to cVA suppresses …

Intersexual signals that reveal developmental or mating status in females have evolved
repeatedly in many animal lineages. Such signals have functions in sexual conflict over …

The concept of evolvability is controversial. To some, it is simply a measure of the standing
genetic variation in a population and can be captured by the narrow-sense heritability (h 2) …

Precise estimates of costs and benefits, the fitness economics, of mating are of key
importance in understanding how selection shapes the coevolution of male and female …

It is increasingly realized that the potential for male mate choice is widespread across many
taxa. However, measurements of the relative magnitude of the fitness benefits that such …

Sexual selection is an important agent of evolutionary change, but the strength and direction
of selection often vary over space and time. One potential source of heterogeneity may lie in …
