Researchers have discovered that plants have the ability to recognize their siblings through their roots and the chemical cues they secrete. The finding not only sheds light on the intriguing sensing system in plants, but also may have implications for agriculture and even home gardening.
Susan Dudley, an evolutionary plant ecologist at McMaster University in Hamilton, Ontario, and her colleagues observed that when siblings are grown next to each other in the soil, they “play nice” and don’t send out more roots to compete with one another. However, the moment one of the plants is thrown in with strangers, it begins competing with them by rapidly growing more roots to take up the water and mineral nutrients in the soil.
“Plants have no visible sensory markers, and they can’t run away from where they are planted,” says Harsh Bais, assistant professor of plant and soil sciences at the University of Delaware. “It then becomes a search for more complex patterns of recognition.”
For christ’s sake, people. It’s a medical device, not a toy for people with unruly children - just like you don’t toss a straitjacket on your spouse every time they raise their voice at you. It’s used for kids who don’t have the ability to control their actions either due to physical or mental conditions in order to keep them from seriously/permanently injuring themselves and others. Say you’re in the ER and you have a panicking kid with a rapidly bleeding wound. Do you have any idea how many people it would take to hold that child down for treatment? Do you know what kind of injuries they and the child can sustain during that? Alternatively, there’s a velcro restraint that can hold them safely in place for treatment and it takes 1-2 minutes to get it on them so treatment can get started. And yes, they make them for adults as well.
If you can’t figure out why such a thing would be necessary, then I’m glad you’ve never had to deal with any situations that would require that. Other people do have to deal with those situations, and this is better than the alternatives. If you still don’t get it, go ask an ER nurse for a full list of situations where this would be needed.
The Turtle Survival Alliance (TSA), in collaboration with The Orianne Society (TOS), hired noted South Africa-based wildlife film makers Moz Images to cover the rapidly worsening crisis with Madagascar’s Radiated Tortoise.
The film crew of Chris Scarfe and Aaron Gekoski accompanied Rick Hudson and Christina Castellano to Madagascar in September 2011 and the resulting short film - Tortoises in Trouble - tracks a group of 140 confiscated Radiated Tortoises from the captital city of Antanananrivo to their homeland in the south where they are repatriated to a sacred protected forest near the village of Ampotoka.
