The Argentine ant is an invasive species that has become a major nuisance in California and southern states, including Georgia, South Carolina. Alabama, Mississippi, Louisiana, Florida, Tennessee and ...
Like people, ants have often fought over food and territory.But ants began fighting long before humans: at least 99 million years ago, according to Phillip Barden, a fossil insect expert who works in ...
A major question in ecology is: how do mutualisms between species affect population dynamics? For four years, we monitored populations of two Amazonian myrmecophytes, Cordia nodosa and Duroia hirsut...
This study investigates variation in collective behavior in a natural population of colonies of the harvester ant, Pogonomyrmex barbatus. Harvester ant colonies regulate foraging activity to adjust t...
Army ants, the nomadic swarming predators underfoot in the jungle, can take down a colony of prey animals without breaking a sweat. But certain army ant species can’t take the heat.According to a new ...
