Global biogeography of ant social parasites: Exploring patterns and mechanisms of an inverse latitudinal diversity gradient

open access: yesJournal of Biogeography, Volume 50, Issue 2, Page 316-329, February 2023., 2023
Abstract Aim One of the most consistent global biogeographic patterns is the latitudinal diversity gradient where species richness peaks within the equatorial tropics and decreases towards the poles. Here, we explore the global biogeography of socially parasitic ant species, which comprises the most diverse group of social parasites in the Hymenoptera.

The ant abdomen: The skeletomuscular and soft tissue anatomy of Amblyopone australis workers (Hymenoptera: Formicidae)

open access: yesJournal of Morphology, Volume 283, Issue 6, Page 693-770, June 2022., 2022
The ant abdomen is critically understudied, despite its functional, evolutionary, and systematic importance. Using physical dissection, scanning electron microscope, histology, and microcomputed tomography, we provide the first complete treatment of the skeletomusculature, exocrine glands, and other major organs of the abdomen.

Ant species that remove diaspores alone are more efficient removers [PDF]

open access: yes, 2022
Secondary diaspore removal on the ground is an important ecosystem process. In this process, solitary foraging ants with larger body sizes are more efficient because they may remove more diaspores, faster and carry them at greater distances.
