Models of reproductive skew: A review and synthesis (Invited Article)
TLDR
It is shown that the division between transactional and compromise models is somewhat artificial, and that both approaches may be combined in a single, synthetic treatment.

TLDR
While some mating preferences did not originally evolve for adaptive reasons, others may or may not have done so, and a review of the published data reveals some support for the ideas of adaptive choice and honest advertisement.
Multiple Displays in Animal Communication:`Backup Signals' and `Multiple Messages'
TLDR
A new game-theoretical model of signalling is described, in which signallers may use more than one display to advertise their qualities, and multiple signals are shown to be stable, even when multiple receiver preferences entail significant costs.
The evolution of cooperative breeding through group augmentation
TLDR
The results show that group augmentation (either passive or active) can be evolutionarily stable and explain costly helping by non–reproductive subordinates, either alone or leading to elevated help levels when acting in concert with kin selection.
MUTUAL MATE CHOICE AND SEX DIFFERENCES IN CHOOSINESS
TLDR
An ESS model of mutual mate choice is presented, which explicitly incorporates differences between males and females in life history traits that determine the costs and benefits of choice, and demonstrates that sex differences in costs of choice are likely to have a much stronger effect on choosiness than are differences in quality variation.
Negotiation over offspring care—how should parents respond to each other's efforts?
TLDR
This model incorporates uncertainty regarding brood need or value into a game-theoretical model of biparental negotiation over offspring care and shows that when each parent has only partial information, greater effort invested by one serves as a signal to the other of brood need, which favors a matching response by the focal parent's mate.
