Multiple mating or group spawning leads to post‐copulatory sexual selection, which
generally favours ejaculates that are more competitive under sperm competition. In four …

In recent years, crayfish aquaculture industry has been developing rapidly in different
regions of the world. Crayfish aquaculture is often carried out in dams, lakes and extensive …

In promiscuous species, male reproductive success is determined by the interaction
between the ability to access and choose females of the highest reproductive quality and …

Mate choice is often assumed to be a prerogative of females because of their putatively
larger reproductive investment than males. However, recent evidence suggests that …

An increasing number of studies test the idea that females increase offspring fitness by
biasing fertilization in favour of genetically compatible partners; however, few have …

Candidate indicators of the direct and indirect effects of fishing can be developed by
investigating fisheries closures. We tested a suite of such indicators in areas open to fishing …

An important predictor of male fitness is the fertilizing efficiency of their ejaculates.
Ejaculates are costly to produce and males are predicted to devote greater resources to …

For their great commercial importance as a human food delicacy, crayfish are now becoming
of wider interest to molecular biologists, and also to conservationists due to the fact that in …

Sperm competition drives traits that enhance fertilization success. The amount of sperm
transferred relative to competitors is key for attaining paternity. Female reproductive …

Growth and reproduction are competitive processes with the first being an essential
prerequisite for the second. In crayfish both of these processes continue until the animal dies …
