They’re everywhere, even the trees. Petr Klimes researches the ecological roles of insects, especially ants in Papua New Guinea, where many species are less accessible for research. He shares interesting ant facts and tales along with questions he’s pursing.

Listen and learn

• How, despite both being social insects, ants interact with their food and world in much more diverse ways than their bee cousins, 
• What interesting examples of parasitism, symbiosis, and mutualism exist in ant species, and
• What next steps Petr Klimes plans to take by researching how ants are responding to climate change and different habitat types available.

Petr Klimes is the laboratory head of the Laboratory of Ecology and Evolution of Social Insects with the University of South Bohemia Biology Centre CAS. He’s interested in ants that live in tropical trees and spread across the islands in the pacific, specifically their evolution and interaction with plants and other animals. One remarkable aspect of ants’ life cycles and habits is the vast diversity among different species.

Unlike bees, which are exclusively pollinators, or wasps, which are predators, ant interactions vary widely. Some are predators, some are omnivores. Some ant colony structures include more than one ant queen and some don’t. Some are highly specialized in food and nest choice and some are opportunistic, eating whatever and living where ever is available.

Petr Klimes spent time in Papua New Guinea comparing ground and arboreal ants. Ground ants are mostly predators, but tree ants tend to work with other insects like aphids. He shares many fascinating examples of ant interactions, from parasitism to symbiotic relationships with plants or other insects like aphids. Unlike ant species in the U.S., which look fairly similar to each other, the morphology in the tropics is extreme.

One species, for example, lives in leaf litter and is about 1 millimeter long, has triangle-shaped “hats” and predates with sharp mandibles, eating tiny, fast-moving insects. In Borneo, another large species lives in trees and are dimorphic, with large soldiers and small foragers. He hopes to embark on a new project soon to study species interaction and biology in terms of how climate change and forest change is influencing ant communities.
