Animal signals
their prominence can be hard for even a casual observer to overlook. Animal signals therefore raise many scientific questions: What are their functions? What information do they transmit? How are… Expand

Models of reproductive skew: A review and synthesis (Invited Article)
Animal societies vary markedly in reproductive skew, the extent to which breeding is monopolised by dominant individuals. In the last few years, a large number of different models have been developed… Expand

(i)  To find out whether a mating preference could have initially evolved for adaptive reasons, one must determine whether the preferred trait could have provided useful information about mate… Expand

Begging the question: are offspring solicitation behaviours signals of need?
Throughout the animal kingdom, distinctive behaviour by offspring commonly precedes and accompanies their provisioning by parents. Here, we assess empirical support for the recent theory that begging… Expand

Multiple Displays in Animal Communication:`Backup Signals' and `Multiple Messages'
TLDR
We propose a new game-theoretical model of signalling, in which signallers may use more than one display to advertise their qualities. Expand

MUTUAL MATE CHOICE AND SEX DIFFERENCES IN CHOOSINESS
Sexual competition is associated closely with parental care because the sex providing less care has a higher potential rate of reproduction, and hence more to gain from competing for multiple mates.… Expand

The evolution of cooperative breeding through group augmentation
Some individuals (helpers) in cooperatively breeding species provide alloparental care and often suppress their own reproduction. Kin selection is clearly an important explanation for such behaviour,… Expand

Social Feedback and the Emergence of Leaders and Followers
In many animal groups, certain individuals consistently appear at the forefront of coordinated movements [1-4]. How such leaders emerge is poorly understood [5, 6]. Here, we show that in pairs of… Expand

Negotiation over offspring care—how should parents respond to each other's efforts?
Models of biparental care predict that parents should compensate incompletely for any change in their partner's investment. Experimental tests have, however, yielded results that range from full… Expand

Integrating cooperative breeding into theoretical concepts of cooperation
In cooperative breeding systems, some individuals help to raise offspring that are not their own. While early explanations for such altruistic behaviour were predominantly based on kin selection,… Expand
