The latitudinal diversity gradient—the tendency for more species to occur toward the equator—
is the dominant pattern of life on Earth, yet the mechanisms responsible for it remain largely …

Aim Continents harbour unique faunas, and only a small percentage of species naturally
inhabit more than a single continent. This pattern is most evident in the insects, a …

It is widely recognised that arid Australia (including semi‐and seasonally arid regions)
supports an extremely diverse ant fauna. However, the truly remarkable extent of its diversity …

Aim Biodiversity patterns reflect both ecological and evolutionary processes interacting with
geographical variation in climate and the current and historical connectivity between land …

The emergence of the Isthmus of Panama is one of the most important events in recent
geological history, yet its timing and role in fundamental evolutionary processes remain …

Fossils provide unique opportunity to understand the tempo and mode of evolution and are
essential for modeling the history of lineage diversification. Here, we interrogate the …

Ants in the genera Anochetus and Odontomachus belong to one of the largest clades in the
subfamily Ponerinae, and are one of four lineages of ants possessing spring-loaded “trap …

While insular radiations are documented for many terrestrial arthropods, few examples are
known for eusocial insects. This study seeks to ascertain whether the spinescence observed …

Aim The latitudinal diversity gradient is the dominant geographic pattern of life on Earth, but
a consensus understanding of its origins has remained elusive. The analysis of recently …

We investigate the species-level taxonomy and evolutionary history of Nearctic ants in the
Crematogaster scutellaris group (Hymenoptera: Formicidae), drawing on evidence from …
