**About the Editor**

**Alan N. Andersen** (Professor). Prof. Andersen is Professorial Fellow—Research Excellence and Impact with Charles Darwin University. Previously, he was the Leader of CSIRO's Tropical Ecosystems Research Centre in Darwin for twenty years. Prof. Andersen's primary research interests are in the global ecology of ant communities, where he integrates community ecology, macroecology, historical and contemporary biogeography, and systematics to gain a predictive understanding of ant diversity, behavioural dominance, and functional composition in relation to environmental stress and disturbance. He applies this understanding to the use of ants as bioindicators of ecological change.
