“…Field work supports this supposition as parental bluegill sunfish showed decreased parental care and increased abandonment of their nests as the percentage of eggs sired by a cuckholder increased (Neff and Gross, 2001). Furthermore, data for both juvenile cichlids (Le Vin, Mable, and Arnold, 2010) and juvenile zebrafish (Gerlach and Lysiak, 2006) support the idea that nepotistic species spend more time investigating the scent of kin rather than non-kin.…”

“…However, divergent proximate and ultimate mechanisms underlie these different group size adjustments. In the experiments of Taborsky [31], familiar offspring of the pair that had been recently expelled were allowed access to the territory again when space competitors were introduced; both individual and kin recognition have been demonstrated in N. pulcher [75,76]. At the ultimate level, such sharing of resources and tasks between breeders and offspring may be explained by kin selection.…”

Group size adjustment to ecological demand in a cooperative breeder

Environmental factors can determine which group size will maximize the fitness of group members. This is particularly important in cooperative breeders, where group members often serve different purposes. Experimental studies are yet lacking to check whether ecologically mediated need for help will change the propensity of dominant group members to accept immigrants. Here, we manipulated the perceived risk of predation for dominant breeders of the cooperatively breeding cichlid fish Neolamprologus pulcher to test their response to unrelated and previously unknown immigrants. Potential immigrants were more readily accepted if groups were exposed to fish predators or egg predators than to herbivorous fish or control situations lacking predation risk. Our data are consistent with both risk dilution and helping effects. Egg predators were presented before spawning, which might suggest that the fish adjust acceptance rates also to a potential future threat. Dominant group members of N. pulcher apparently consider both present and future need of help based on ecological demand. This suggests that acceptance of immigrants and, more generally, tolerance of group members on demand could be a widespread response to ecological conditions in cooperatively breeding animals.

“…However, since then, evidence has emerged that direct cues to genetic relatedness exist in many species including cooperative breeders and other group‐living species (e.g. cooperatively breeding meerkats (Leclaire et al ., ); Neolamprologus pulcher cichlids (Le Vin, Mable & Arnold, ) and bell miners Manorina melanophrys (McDonald & Wright, ); and group‐living Belding's ground squirrels Urocitellus beldingi (Mateo, ) and zebrafish Danio rerio , (Gerlach & Lysiak, )). Such mechanisms are likely to be involved in inbreeding avoidance and can be effective even without environmental and social cues to relatedness.…”

The causes and consequences of inbreeding avoidance and tolerance in cooperatively breeding vertebrates

Cooperative breeders provide a particularly interesting scenario for studying inbreeding. Such populations are viscous due to delayed dispersal and short dispersal distances, resulting in the build-up of relatives in the local population. This leads to a high risk of inbreeding, and consequently of inbreeding depression. This has driven the evolution of an array of inbreeding avoidance mechanisms resulting in a relatively low level of close inbreeding in the majority of cooperative breeders. However, there are a number of species where inbreeding occurs relatively frequently. The presence of regular inbreeding (in cases where inbreeding is not a result of recent population declines), suggests that inbreeding tolerance and even preference can evolve under some circumstances. Both inbreeding and inbreeding avoidance mechanisms have enormous downstream fitness consequences for cooperative breeding species. For example, they can influence reproductive dynamics leading to a monopolization of breeding opportunities by dominant individuals. Inbreeding and its avoidance are also likely to impact on the evolution of cooperative breeding itself through influencing levels of relatedness between potential cooperators. Finally, in some cooperative breeders, a high degree of inbreeding avoidance can be detrimental to population viability, and hence is of particular concern to conservationists. In this review, I discuss these issues in detail and also briefly consider recent advances in the methods available for the study of inbreeding in natural populations.
