Damaraland mole-rats do not rely on helpers for reproduction or survival
In eusocial invertebrates and obligate cooperative breeders, successful reproduction is
dependent on assistance from non-breeding group members. Although naked …

Should sons breed independently or help? Local relatedness matters
In cooperatively breeding birds, why do some individuals breed independently but others
have to help at home? This question has been rarely addressed despite its fundamental …

Michener's group-size paradox in cooperatively breeding birds
PA Downing - Journal of Evolutionary Biology, 2024 - academic.oup.com
According to Michener's paradox, most altruistic groups in nature should be small and large
groups should not exist. This is because per capita productivity is thought to decrease as …

Family living and cooperative breeding in birds are associated with the number of avian predators
Cooperative breeding occurs when individuals contribute parental care to offspring that are
not their own. Numerous intra-and inter-specific studies have aimed to explain the evolution …

Early-life sibling conflict in Canada jays has lifetime fitness consequences
While delaying natal dispersal can provide short-term benefits for juveniles, lifetime fitness
consequences are rarely assessed. Furthermore, competition for limited positions on a natal …

Staging to join non‐kin groups in a classical cooperative breeder, the Florida scrub‐jay
Why unrelated members form groups in animal societies remains a pertinent topic in
evolutionary biology because benefits for group members often are not obvious. We studied …
