Species richness (Alejandro)

Hello Antweb,
I've been doing some research on ant species richness and was wondering what locality is considered to have the highest species richness and if there is any literature to back up this information, thanks!

Hi Alejandro,

Ant diversity is highest at low latitudes (the tropics) and drops off towards the poles. This is a common phenomenon among many groups of organisms and Terry McGlynn has a relatively accessible piece about it here. This website is also a great way to explore the distribution of ant genera across the world. There is quite a bit of literature on the subject including, but certainly not limited to, the references listed below and the citations therein. The book "Ant Ecology", listed first in the below references, is a great overview of many ant related subjects, including their geographic distribution.

Thanks for your question,
Ben Rubin & the AntAsk Team
