A nice paper on coatis from a multitude of institutions the other side of the pond (including Ohio State, the Smithsonian and Georgetown University) has found support for the idea that the sub-adult years can be tricky for more than just humans, with adult females protecting the younger juveniles in squabbles over food.
In Kinship Shapes Affiliative Social Networks but Not Aggression in Ring-Tailed Coatis, Hirsch et al. looked at grooming, agonistic and associative behaviours in Nasua nasua and constructed (wait for it) networks and matrices to look at how these behaviours worked between individuals and classes. Adult females were found to protect juveniles in altercations with older coatis, even when adult and juvenile were unrelated.
They also use the daringly titled multiple regression quadratic assignment procedures (MRQAP), which I’ve a feeling I’ll need to learn quite a lot about…
