CONSIDERABLE INDIVIDUALITY. "This model suggests that pest attack results in effectively random resistance responses in identical tissues such as leaves. Indeed, data provided by these authors indicate that on a single tree every leaf was observed to be at a different stage of pest resistance." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

Gothic alabaster tombs and sculptures were unable to use mechanical friction to melt the upper layer of rock and achieve a high gloss shine, due to the lack of machines, and the surfaces were polished by specialty tradesmen for many months to achieve a partial glass, and often also painted by a separate trade.

SO ENDS this first of two weekends on the biological implications of a south African termite mound that serves as a breathing organ for the superorganism, how it is constructed, functions, and is repaired upon damage. The repair function relies on short lived workers who must somehow analyze the damage and also transmit enough knowledge of the structure to the next generation of workers. It is this repair process that is so interesting, and its implications for Darwinian evolution. View in LinkedIn

THE INJURY TEST OF MEMORY. “For the mound to serve its respiratory function, the colony must have knowledge, in some form, of how the mound is structured. That the colony has such knowledge is revealed dramatically by the response to mound injury, such as a breach of the mound surface by a soil auger. This initiates an immediate repair program that plugs the damaged mound, usually in less than a day, and often within a few hours of the injury. This is followed by an extended process of remodeling that, over periods that can span years, restores the damaged part of the mound to its form and functionality prior to the injury.” https://link.springer.com/article/10.1007/s12304-016-9256-5 View in LinkedIn

TREE KIN RECOGNITION. "We know that big old trees—we call them mother trees—will communicate with seedlings that are their kin or their kids and make room for those kids compared to seedlings that are strangers, and they are doing this through their mycorrhizal networks." http://www.abc.net.au/radionational/programs/futuretense/the-underestimated-power-of-plants/7227008 View in LinkedIn

COMPLEX PROBLEM. "It is very clear that the construction and maintenance of an accurate spatial map of a large plant such as a tree would demand huge processing power. Thousands of leaves and roots, each having a need to sense their local environment to serve their own needs, would produce very large amounts of data. The data would be changing by the minute as the leaves fluttered in a breeze and the roots explored their very heterogeneous environment." http://aob.oxfordjournals.org/content/93/4/345.full View in LinkedIn

SUN PLANTS "do not react passively to the light mosaic in a canopy, simply accumulating dry weight when the light is strong enough. The quality and quantity of light is actively perceived (through red : far red ratios) and the position of likely future competitive neighbours mapped." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn

SMART FEEDING BY DODDER. "By using a range of hosts of different reward value, measuring the length of coils and the biomass subsequently accumulated after 28 d, it was shown that the length of coiling was linearly related to subsequent reward/unit of energy invested." http://aob.oxfordjournals.org/content/92/1/1.full View in LinkedIn
