Behavioural Ecology: Cuckolder Eggs Come First
نویسنده
چکیده
In mixed paternity broods, extra-pair offspring often perform better than their maternal half-siblings. This has been interpreted as evidence for genetic benefits of female promiscuity, but a new study shows that the difference in fitness may be largely due to a non-genetic, maternal effect.

Tactic-specific success in sperm competition.
Sperm competition is a major force in sexual selection, but its implications for mating-system and life-history evolution are only beginning to be understood. The well-known sneak-guard model predicts that sneaks will win in sperm competition. We now provide empirical confirmation of this prediction. Bluegill sunfish (Lepomis macrochirus) have both sneak (cuckolder) and guard (parental) males. ...
متن کاملGenetic life history effects on juvenile survival in bluegill.
Foraging behaviour under the risk of predation has important consequences on an individual's survivorship and fitness. In bluegill (Lepomis macrochirus), we have recently shown that offspring sired by males of alternative life histories differ in their foraging behaviour. Specifically, offspring sired by 'cuckolder' males take fewer risks during foraging than do offspring sired by 'parental' ma...
متن کاملUsing Sex Ratios to Estimate What Limits Reproduction in Parasitoids
The reproductive success of a foraging parasitoid may be limited by the number of eggs that she produces and/or the number of hosts that she can locate. Despite the significance for population dynamics and numerous areas of behavioural ecology, the relative importance of these factors remains an issue of contention. Attempts to resolve this controversy have been hindered because estimating the ...

In the cooperatively breeding superb fairy-wren, helpers have negligible effect on breeding success. So why help? The answer is hidden in the size of the eggs.
متن کاملSteroid hormones in bluegill, a species with male alternative reproductive tactics including female mimicry.
The proximate mechanisms underlying the evolution and maintenance of within-sex variation in mating behaviour are still poorly understood. Species characterized by alternative reproductive tactics provide ideal opportunities to investigate such mechanisms. Bluegill (Lepomis macrochirus) are noteworthy in this regard because they exhibit two distinct cuckolder (parasitic) morphs (called sneaker ...
