Sex and friendship in baboons
TLDR
The findings suggest that the evolution of male reproductive strategies in baboons can only be understood by considering the relationship between sex and friendship: female baboons prefer to mate with males who have previously engaged in friendly interaction with them and their offspring.
Quantity-based judgments in the domestic dog (Canis lupus familiaris)
TLDR
The results suggest that, like apes tested on similar tasks, some dogs can form internal representations and make mental comparisons of quantity.
Use of signature whistles during separations and reunions by wild bottlenose dolphin mothers and infants
TLDR
Whistles occur primarily when mother-infant pairs are separated, and the probability of whistles increases with distance of separation, but whistles tend to be produced in repetitive series and are generally concentrated toward the later stages of the separation, i.e., during the process of reunion.

TLDR
