Family living and cooperative breeding in birds are associated with the number of avian predators

Evolution, Journal Year: 2024, Volume and Issue: 78(7), P. 1317 - 1324

Published: April 23, 2024

Abstract Cooperative breeding occurs when individuals contribute parental care to offspring that are not their own. Numerous intra- and interspecific studies have aimed explain the evolution of this behavior. Recent comparative work suggests family living (i.e., remain with parents beyond independence) is a critical stepping stone in cooperative breeding. Thus, it key understand factors facilitate living. Within-species suggest protection from predators function group living, through both passive benefits such as dilution effects active prosocial antipredator behaviors groups. However, association between predation risk formation prevalence groups remains untested globally. Here, we use phylogenetic analyses including 2,984 bird species show associated increased occurrence avian predators. These cross-species findings lend support previous suggestions based on intraspecific social against predation, could favor delayed dispersal

Evidence for a reproductive sharing continuum in cooperatively breeding mammals and birds: consequences for comparative research

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2023, Volume and Issue: 290(2006)

Published: Sept. 13, 2023

Extreme reproductive skew occurs when a dominant female/male almost monopolizes reproduction within group of multiple sexually mature females/males, respectively. It is sometimes considered an additional, restrictive criterion to define cooperative breeding. However, datasets that use this definition classify species as breeders systematically overestimate by including groups in which cannot be shared (e.g. with single female/male). Here, we review the extent sharing 41 mammal and 37 bird previously classified exhibiting alloparental care extreme skew, while only considering multi-female or multi-male groups. We demonstrate where unequal possible, few (11/41 12/37 species). These results call for significant changes species' caring mating system. To facilitate these changes, provide updated dataset on 63 cooperatively breeding species. At conceptual level, our findings suggest should not defining support system alloparents systematic other members' offspring.

The power of touch: from survival to enduring, prosocial cooperation

Published: Jan. 13, 2024

Cooperation is a pivotal biological phenomenon that occurs in many forms. In species engage helping, individuals vary association time and the extent of physical proximity, influencing touching between individuals. Here, we emphasize importance touch development maintenance parenting mate bonds, its link to cooperation. Touch activates feedback loop via social hormones supports bonds general. Notably, extended crucial for emergence enduring mindset investments which result delayed benefits. We integrate these ideas ‘caring-touch’ hypothesis, highlighting role evolution different forms

Digest: Cooperative breeding strategies in birds are shaped by avian predator richness

Evolution, Journal Year: 2024, Volume and Issue: 78(10), P. 1746 - 1747

Published: July 31, 2024

Abstract Despite their prevalence, family-living and cooperative breeding in birds have received little examination as to how why they vary across species. Investigating the evolution of these social systems, Bliard et al. (2024) found that presence avian predators is associated with birds’ increases predator corresponding multiple shifts from non-family-living breeding. Phylogenetic comparative analyses indicate factors outside season can be selected for
