A century ago, foundational work by Thorleif Schjelderup-Ebbe described a 'pecking order'in
chicken societies, where individuals could be ordered according to their ability to exert their …

Although social hierarchies are recognized as dynamic systems, they are typically treated as
static entities for practical reasons. Here, we ask what we can learn from a dynamical view of …

In many animal societies, individuals differ consistently in their ability to win agonistic
interactions, resulting in dominance hierarchies. These differences arise due to a range of …

The fighting fish Betta splendens, long studied for its aggressive territorial competitions, has
the potential to be a tractable and relevant model for studying the intersection of cognitive …

Chicken dominance hierarchies or pecking orders are established before maturation and
maintained by consistent submissive responses of subordinate individuals, leading to stable …

Individuals vary in their access to resources, social connections and phenotypic traits, and a
central goal of evolutionary biology is to understand how this variation arises and influences …
