Social systems are the outcomes of natural and sexual selection on individuals' efforts to
maximize reproductive success. Ecological conditions, life history, demography traits and …

Studies of cetacean evolution using genetics and other biomolecules have come a long way—
from the use of allozymes and short sequences of mitochondrial or nuclear DNA to the …

Since 1985 a resident community of Atlantic spotted dolphins (Stenella frontalis), and
bottlenose dolphins (Tursiops truncatus), have been studied underwater in the Bahamas …

Long‐term social structure data on small delphinids is lacking for most species except the
bottlenose dolphin. This study describes the long‐term social structure of one community of …

The primary purpose of sex is reproduction. However, because not all mating events result
in fertilization and only a small number of species provide biparental care to their young …

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 …

Extreme environmental events and demographic changes can have variable effects on the
social structure of animal populations. This study compared the social structure of a …

Fission‐fusion dynamics typical of many delphinid populations allow for a variety of social
grouping patterns. Identifying these groupings is crucial before conducting a detailed social …

With the exception of primates, detailed interspecies behavioral studies are rare in
mammalian species and for cetaceans, most are anecdotal descriptions. This study is the …

Individuals in social species may mate with multiple opposite-sex individuals, including
members of the same or different social groups. This variation may be linked to genetic …
