What is a Supercolony?

There’s been a debate simmering among Argentine Ant researchers about the difference between the ant’s ecology in its native South America and in the introduced populations.  The heart of the disagreement is this:  is the introduced Argentine ant dominant because its biology changed during introduction, or because the ecologies of the native and introduced ranges [...]
