FRAGMENT FROM NATURE for the next two weekends will focus on the topic of leafcutter (Attine) ant farming. These lovely creatures have some of the most elaborate symbiotic relationships known: they cultivate a fungus for food, cultivate a bacteria to give that crop antibiotic treatments, and cultivate nitrogen-fertilizing bacteria as fungal food. And they have been at this for over 50 million years. These are the ultimate sustainable organic farmers. View in LinkedIn

NEW FUNGAL VARIETIES. "∼22 million years ago, the association between a particular lower-attine ant and its leucocoprineaceous fungal cultivar underwent a fundamental change, giving rise to higher-attine agriculture. More recently, 2–8 million years ago, a higher-attine cultivar species gave rise to a new, even more specialized fungal species, Leucoagaricus gongylophorus, presumably as the result of prolonged domestication by and/or coevolution with a leaf-cutting ant species." https://lnkd.in/et8V2SM View in LinkedIn

QB SECTION END. This ends this large section on Quantum Biology. What is clear is that increasing phenomena in biology are ascribed to QB mechanisms, as our understanding deepens. This field is in its infancy, and practical applications are just starting to emerge with the confluence of nanoelectronics and biological molecules known to have QB mechanisms. https://lnkd.in/evm-KtE View in LinkedIn

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
