Efforts to understand human social evolution rely largely on comparisons with nonhuman
primates. However, a population of bottlenose dolphins in Shark Bay, Western Australia …

Abstract In Shark Bay, Western Australia, male bottlenose dolphins form a complex nested
alliance hierarchy. At the first level, pairs or trios of unrelated males cooperate to herd …

Vocal interactions are intrinsic features of social groups and can play a pivotal role in social
bonding. 1, 2 Dunbar's social bonding hypothesis posits that vocal exchanges evolved to" …

While the ontogeny of beluga (Delphinapterus leucas) socio-sexual behavior has been
documented in animals between 37-and 108-months-old, the first 36 months of life are yet to …

Research on sex biases in longevity in mammals often assumes that male investment in
competition results in a female survival advantage that is constant throughout life. We use 35 …

Bottlenose dolphins are a behaviorally complex, social species that display a variety of
social behaviors. Because of this, it is important for zoological facilities to strive to ensure …

In mammals, reproductive success can often be directly observed for females, but not males.
Early-life correlates of female reproductive success can also be easier to observe due to …

Conspecifics may vary in their space use and diet leading to niche partitioning within
populations. In social species, such partitioning may correspond to social structure as …

Investigations of population structure across multiple niche dimensions can identify discrete
management units within populations. This study examined social, spatial and isotopic niche …

Elucidating the mechanisms underlying differentiation between populations is essential to
our understanding of ecological and evolutionary processes. While social network analysis …
