Ants Grow Their Thoracic Segments To Match The Tasks They Perform

Instituto Gulbenkian de Ciencia It has now been discovered that the specialization of queen and worker ants goes beyond the presence or absence of wings. In a study published in the open access scientific journal eLife, Roberto A. Keller and Patrícia Beldade from the Instituto Gulbenkian de Ciência (IGC, Portugal), in collaboration with Christian Peeters from Université Pierre et Marie Curie (France), showed that ants grow the size of their thoracic segments differently according to the...

The development of agriculture was a significant event in human cultural evolution, but we are not the only organisms to have adopted an agricultural way of life. In a study published online June 29 in Genome Research, researchers have sequenced the genome of a fungus farming leaf-cutting ant, revealing new insights into the genetics and molecular biology behind this unusual lifestyle. Found in Central and South America as well as the southern United States, leaf-cutting ants have evolved a...

Scientists at the University of East Anglia, have shown that fungus-farming ants are using multiple antibiotics as weed killers to maintain their fungus gardens.Research led by Dr Matt Hutchings and published today in the journal BMC Biology  shows that ants use the antibiotics to inhibit the growth of unwanted fungi and bacteria in their fungus cultures which they use to feed their larvae and queen.These antibiotics are produced by actinomycete bacteria that live on the ants in a mutual...

Fungus-farming ants have cultivated the same fungal crops for 50 million years. Each young ant queen carries a bit of fungus garden with her when she flies away to mate and establish a new nest. Short breaks in the ants' relationship with the fungus during nest establishment may contribute to the stability of this long-term mutualism, according to a study at the Smithsonian Tropical Research Institute in Gamboa, Panama. "We were struck by the paradox that even though the ants transfer a...

Leafcutter ants are found in warmer regions of Central and South America. These remarkable social insects have evolved an advanced agricultural system. They feed on a specialized fungus that grows only in the underground chambers of the ants' nest. The ants actively cultivate their fungus, feeding it with freshly-cut vegetation and maintaining it free from pests and weeds. This is done by a symbiotic relationship with a colony of bacteria that grows on the ants that protect the fungus. The...
