Conditions Influencing Aggression

Animals commonly alter their behavior in the
presence of other animals. This is particularly true
in the context of aggressive exchanges, where
individuals alter behavior to influence and form
social relationships. Hierarchical relationships
are widespread across taxa, yet the dynamic processes
that produce them remain poorly understood. In
particular, the exchange of information during fight
interactions and how such information exchanges
influences hierarchies remains elusive. In crayfish
as in many other animals, dominance is thought to be
primarily determined by physical superiority, where
behavior and fight outcomes become predictable.
However recent evidence has shown that aggressive
encounters are dependent upon a myriad of factors
outside of physical superiority and makes fight
outcomes less predictable. This book provides an
analysis of various extrinsic and intrinsic factors
that influence fighting. Some of the variables
examined include habitat preference, fluid flow,
chemical signal use, previous social history, and
neurochemical alterations. It also discusses how
extrinsic and intrinsic factors are used to modify
and maintain social hierarchies.
