1. In social mammals where group members cooperate to detect predators and raise young, members of small groups commonly show higher mortality or lower breeding success than members of large ones. It is generally assumed that this is because large group size allows individuals to detect or repel predators more effectively but other benefits of group size may also be involved, including reduced costs of raising young and more effective competition for resources with neighbouring groups. 2.

Variable fledging age according to group size: trade-offs in a cooperatively breeding bird

The optimal age to fledge young appears to depend on the trade-off between reduced nestling predation and increased fledgling mobility, and it is suggested that such trade-offs may be common in species where group size critically affects individual survival and reproductive success.

Predation risk is an ecological constraint for helper dispersal in a cooperatively breeding cichlid

The results demonstrate the importance of predators for group living in this species, and support the ‘ecological constraints hypothesis’ of cooperative breeding, in the sense that subordinates stay at home rather than leave and breed independently under the risk of predation.

Anti-predator benefits of group living in white-nosed coatis (Nasua narica)

White-nosed coatis exhibit a suite of behaviors, including foraging with the juveniles in the center of the group, sharing vigilance, alarm calling, mobbing and attacking predators, and a highly synchronous birth season, that are consistent with the hypothesis that predation has played an important role in shaping coati social behavior.

Anti-predator beneIS of group living in white-nosed coatis

White-nosed coatis exhibit a suite of behaviors consistent with the hypothesis that predation has played an important role in shaping coati social behavior, including foraging with the juveniles in the cen- ter of the group, sharing vigilance, alarm calling, mob- bing and attacking predators, and a highly synchronous birth season.

Large group size yields group stability in the cooperatively breeding cichlid Neolamprologus pulcher

This is the first study showing long-term benefits of large group size in a cooperatively breeding fish, and the importance of differential survival and dispersal of group members for the demonstrated group size effects is discussed.

First- and second-order sociality determine survival and reproduction in cooperative cichlids

It is argued that a full understanding of the adaptive value of cooperation and the evolution of complex social organization requires identifying the effect of different levels of social organization on direct and indirect fitness components.

Opposing effects of group size on reproduction and survival in African wild dogs

The results suggest that cooperative breeding in wild dogs cannot be fully explained by mutual direct benefit, thus reinforcing the prior inference that kin selection plays an important role in the evolution of their cooperation and weakening support for the hypothesis that wild dogs are extinction prone due to group-level Allee effects.



Reproduction and survival of suricates (Suricata suricatta) in the southern Kalahari

The demography of Kalahari suricates (Suricata suricatta) resembles that of other social mongooses, but high rates of group extinction have been found in other cooperative breeders and may occur because breeding success and survival show inverse density dependence.

Why Are Diurnal Primates Living in Groups

A critical test is proposed of the hypothesis that increasing group size should lead to reduced predation risk by comparing demographic patterns between areas where predators are still present and where they have disappeared and the results provide strong support for the predation-feeding competition theory.

Costs of cooperative behaviour in suricates (Suricata suricatta)

Here it is provided of one form of cooperative behaviour that is seldom performed by parents and has substantial energetic costs to helpers, in the cooperative mongoose, Suricata suricatta, non–breeding adults commonly babysit young pups at the natal burrow for a day at a time.

Diet and foraging behaviour of group‐living meerkats, Suricata suricatta, in the southern Kalahari

The timing of foraging activity altered over the months in response to changes in daylength and thermoregulatory constraints, and the implications of an insect prey base for meerkat socioecology are discussed.

The costs and effectiveness of vigilance behaviour in the Dwarf Mongoose: implications for fitness and optimal group size

Group size is shown to be a function of the efficiency of group protection mechanisms such as vigilance and group attack of ground predators and Maximal fitness gains at the level of the individual are attained at a group size lower than the observed mean group size.

Band Structure and Failures of Reproductive Suppression in a Cooperatively Breeding Carnivore, the Slender-Tailed Meerkat (Suricata Suricatta)

The data show that meerkats employ a range of reproductive strategies: bands exhibiting a spectrum of reproductive suppression coexist, and individuals respond to the opportunities afforded by their social environments.

‘Helpers’in fox society

It is reported that non-breeding vixens occur in fox groups in some habitats and are subordinate to the breeding females, and may feed, guard, groom and play with the cubs of the breeding vixen within their group.

Dispersal and extra-territorial prospecting by slender-tailed meerkats (Suricata suricatta) in the south-western Kalahari

Dispersal in slender-tailed meerkats or suricates, Suricata suricatta, in the south-western Kalahari occurred mainly during the early breeding season, and was age- and sex-dependent. Among yearlings,
