MINDSET DIFFERENCES. "Molecular biologists and physicists tend to ask different questions when presented with the same biological system. For example, when considering a network of interacting proteins, a biologist may first ask about the chain of events that occurs after one protein binds to another, whereas a physicist might want to know the rate constants of all the reactions." https://lnkd.in/eVFhtfq View in LinkedIn

ANT FARMERS. "Leafcutter ants are often compared to farmers, and the analogy works on many levels. They apply fertilisers to their crops, in the form of bacteria that provide nitrogen to the fungal gardens. They also use pesticides— they grow antibiotic-secreting bacteria that disinfect the fungi of parasites or competitors. https://lnkd.in/ekUnHks View in LinkedIn

EO WILSON AND BERT HÖLLDOBLER on the superorganism, based on their work on ants, which is midway between an organism and the entire species. Remarkable men, remarkable concept. Between them, they know more than anybody else about ants. No article on ants could be complete without homage to these two men. https://lnkd.in/ebEGeFc View in LinkedIn

TALKING FUNGUS. "Leaf cutter ants are sensitive enough to adapt to the fungi's reaction to different plant material, apparently detecting chemical signals from the fungus. If a particular type of leaf is toxic to the fungus, the colony will no longer collect it. The only two other groups of insects to use fungus-based agriculture are ambrosia beetles and termites." https://lnkd.in/ej4XkBq View in LinkedIn

GONOGLIDIA. "In return for receiving a continuous supply of leaf-material, protection from competitors, and dispersal, the fungus these ants grow provide nutrients in the form of specialized hyphal swellings called gongylidia. Gongylidia, which contain a mixture of carbohydrates, amino acids, proteins, lipids, and vitamins, is the sole food source for developing larvae." https://lnkd.in/eCSpjH7 View in LinkedIn

HUNTERS AND CHEWERS. "The leaves in the rain forest have toxic qualities in them which is supposed to deter herbivory. But the harvesting ants cut the leaves without ingesting any of the toxins and are able to bring the leaves back to the nest. There the leaves are given to worker ants which chew up the leaves in their mouths into a paste which becomes the food source for the fungus." https://lnkd.in/eneZexX View in LinkedIn

GIANT FARMS. Leafcutter ants' "nests' enormous sizes (up to 5000 gardens) and extended lifespans (10–20 years). Atta gardens are discrete units, with an average garden size of about 30×20×20 cm3...the hundreds of Atta gardens can be spaced across an underground volume exceeding 1000 cubic meters...A. texana and A. cephalotes are leafcutter ants with enormous colonies (more than 2 million workers)." https://lnkd.in/ew5j47P View in LinkedIn
