Are they invasive? If so, why? I am writing a script on why pavement ants are so dominant, and this is probably part of the reason. Can anyone provide sources? I'll credit you.

Tetramorium immigrans is native to Europe, therefore invasive, and can displace natives by out competing them in matters of nesting sites and food. https://antmaps.org/...ium.immigrans 

 

See additional sources on that page. They were transported by humans, the exact method unknown, as it was clearly fairly long ago.

Is that map copyright free? So I can use the map in my video.

Also, do pavement ants have any advantages for being invasive?

I am not sure on the issue of copyright on that site.

Tetramorium immigrans is remarkably efficient with small amounts of food.

 

I've observed many battles of this species, and never once have I seen them actually raid a rival colony. Instead, whoever 'wins' these battles basically gains territory. Because of this, when a large colony's queen dies of old age or something else, and that colony fizzles out, there's often small colonies, who have been just scraping by, waiting to take it's place. This keeps the area dominated by Tetramorium, not allowing native ants to gain any sort of foothold.

 

There's many other reasons, too, like their fast growth and how much resources they pour into reproduction.

Yep, I've mentioned that in my prewriting.
