Kin recognition in Drosophila: the importance of ecology and gut microbiota
The animal gut commonly contains a large reservoir of symbiotic microbes. Although these
microbes have obvious functions in digestion and immune defence, gut microbes can also …

COSTS AND BENEFITS OF LIFETIME EXPOSURE TO MATING RIVALS IN MALE DROSOPHILA MELANOGASTER
Abstract Theory predicts that males should evolve mechanisms to assess competition and
allocate resources accordingly. This requires phenotypic plasticity, to accurately match …

[HTML][HTML] Male control of mating duration following exposure to rivals in fruitflies
Males of many species assess the likely level of sperm competition and respond adaptively,
for example by increasing the level of courtship they deliver, by transferring more sperm or …

Playing to the crowd: Using Drosophila to dissect mechanisms underlying plastic male strategies in sperm competition games
Post-copulatory sexual selection, the post-mating competition between ejaculates, is now
widely established as a potent evolutionary driver. However, the competitive environment …

Spatially clustered resources increase male aggregation and mating duration in Drosophila melanogaster
Highlights•Perceived sperm competition risk alters male behaviour linked to sexual
fitness.•The cues driving plasticity in the wild have not been well explored.•We show …

True polyandry and pseudopolyandry: why does a monandrous fly remate?
Background The rate of female remating can have important impacts on a species, from
affecting conflict and cooperation within families, to population viability and gene flow …

Assessment of Rival Males through the Use of Multiple Sensory Cues in the Fruitfly Drosophila pseudoobscura
Environments vary stochastically, and animals need to behave in ways that best fit the
conditions in which they find themselves. The social environment is particularly variable, and …

Current sperm competition determines sperm allocation in a tephritid fruit fly
S Abraham, MT Vera, D Pérez‐Staples - Ethology, 2015 - Wiley Online Library
Sperm competition (SC) occurs when the sperm of two or more males compete for the same
set of ova. Theoretical models and experimental observations indicate that the presence of …

The heritability of mating behaviour in a fly and its plasticity in response to the threat of sperm competition
Phenotypic plasticity is a key mechanism by which animals can cope with rapidly
changeable environments, but the evolutionary lability of such plasticity remains unclear …
