Sep 21, 2022 · We made global maps for ants with estimates per 400 sq km grid cell for species richness (number of species) and range rarity (species richness weighted higher for small-ranged species). Species with small ranges have a higher extinction risk and are thus important targets for conservation.
The website features a series of interactive maps showing where each of the world's 15,000 or so known ant species and subspecies roam. The overview shows the total number of species found in each country or region. Greenland has no native ant species, whereas Queensland, Australia, has 1458.

Invertebrates constitute the majority of animal species and are critical for ecosystem functioning and services. Nonetheless, global invertebrate biodiversity patterns and how they relate to vertebrate biodiversity remain largely unknown. Like other invertebrates, ants are important for the functioning of ecosystems. They aerate soil, disperse seed...
We used existing knowledge about biodiversity along with range modelling and machine learning to create a high-resolution (~20 km) map of the global diversity of ants and predict where undiscovered diversity is likely to exist. Biodiversity among ants and other invertebrates is still poorly understood. We do not have good answers to basic questions...
This project began a decade ago with Benoit Guénard (then at the Okinawa Institute of Science and Technology, now at the University of Hong Kong) and Evan Economo (currently at Harvard). They set out to create a database of occurrence records for different ant species from online repositories, museum collections and around 10,000 scientific publica...
However, there was another problem to overcome: sampling bias. Some parts of the world that we expected to have high levels of diversity were not showing up on our map, but ants in these regions were not well studied. Other areas were extremely well sampled, for example, parts of the USA and Europe. This difference in sampling can impact our estima...
Smallest ant species. The world's smallest ants are those in the genus Carebara. In Sri Lanka, Carebara bruni reaches a total length of 0.8–1.0 millimetres (0.31–0.39 inches), and in Fiji Carebara atomi has been measured over the same range.
Jan 26, 2024 · The smallest ant species is the Carebara atoma, known for its minuscule size. These tiny ants are a fascinating example of insect diversity and have unique behaviors and impacts on their ecosystems.
