Some will be eaten by narrow-nosed crocodiles, lizards or viper-like snakes, and the rest will be lost among the hundreds of millions of poisonous toads that are already scurrying around. But Tizard conceived a career in education for them. Studies conducted on marsupial martens show that they can be taught to stay away from toads. If you feed them toad "sausages" laced with an emetic, they will associate toads with nausea and avoid them. Poison-free toads, according to Tizard, could be an even better learning tool: “If a predator eats them, it will get sick, but not die, and then it will decide:“ I will never eat a toad again.
But in order for such toads to be used to train martens - or for whatsapp mobile number list any other purpose - you need to obtain a number of state licenses. Nettle evokes unpleasant sensations from childhood. However, environmental scientist Aimee Brett from the British University of Nottingham Trent calls for "learning to love" this plant. Understanding why Why nettle stings Animals (rabbits, sheep, deer) eat nettles with a large number of burning hairs in smaller quantities. It's all about the plant's self-defense mechanism. Stinging nettle leaves and stems have small hairs that, when in contact with the skin, remain in it and then release irritants such as histamine.
Nettle is a very strong and hardy plant. Intensive agriculture , urban sprawl and pollution are destroying nature . Climate change makes it harder for plants to grow. However, nettle is a very resistant plant. Its seeds can lie in the soil for at least five years and then germinate. And difficult to uproot are a kind of superpower that helps to quickly create new populations. Charles Darwin's theory that nettle seeds could survive long periods of soaking in salt water turned out to be correct. A 2018 study found that sea water played.
