AMKK（東 信、花樹研究所） Scientists Discover Plants Have "Brains" That Determine When They Grow. Plants have a long and unexpected evolutionary lineage.
Land plants evolved 450 million years ago, but sharks are older than trees; flowers didn’t appear until the Cretaceous Period, and grass only starting sprouting 40 million years ago. Kenny Ausubel: Imagining Our Way Out of the Unimaginable. This Incredible Flower Timelapse Took 3 Years and 8TB of Photos to Create. Filmmaker Jamie Scott made his name in the timelapse space with Fall, a Central Park timelapse of epic proportions that took 6 months of dedication to capture.
And yet his followup timelapse, titled Spring, somehow puts his first creation to shame. Spring is the flower timelapse to end all flower timelapses. “All in all this took 3 years to shoot,” writes Jamie on Vimeo. Svt. Remarkable Photos Capture the Light That Plants Emit. The plants in Craig Burrows’ photos look like something plucked from an alien planet, sprouting wild shades of violet, pink and green.
But the plants, and the colors are real. It’s the result of a cool trick of nature. All plants reflect light. Leaves reflect green, and flowers reflect red, or yellow, or whatever. But plants also fluoresce, which means when they absorb ultraviolet light, they emit longer wavelengths visible to the human eye. SEED: The Untold Story. Ancient plants reawaken: Plants exposed by retreating glaciers regrowing after centuries entombed under ice.
When University of Alberta researcher Catherine La Farge threads her way through the recently exposed terrain left behind by retreating glaciers, she looks at the ancient plant remains a lot closer than most.
Now, her careful scrutiny has revealed a startling reawakening of long-dormant plants known as bryophytes. La Farge, a researcher in the Faculty of Science, and director and curator of the Cryptogamic Herbarium at the University of Alberta, has overturned a long-held assumption that all of the plant remains exposed by retreating polar glaciers are dead. Previously, any new growth of plants close to the glacier margin was considered the result of rapid colonization by modern plants surrounding the glacier. Plants 'do maths' to control overnight food supplies. Plants have a built-in capacity to do maths, which helps them regulate food reserves at night, research suggests.
UK scientists say they were "amazed" to find an example of such a sophisticated arithmetic calculation in biology. Mathematical models show that the amount of starch consumed overnight is calculated by division in a process involving leaf chemicals, a John Innes Centre team reports in e-Life journal. Birds may use similar methods to preserve fat levels during migration. The scientists studied the plant Arabidopsis, which is regarded as a model plant for experiments. 'Astonished' Overnight, when the plant cannot use energy from sunlight to convert carbon dioxide into sugars and starch, it must regulate its starch reserves to ensure they last until dawn.
Plants perform molecular maths. Nigel Cattlin/Getty As if making food from light were not impressive enough, it may be time to add another advanced skill to the botanical repertoire: the ability to perform — at least at the molecular level — arithmetic division.
Computer-generated models published in the journal eLife illustrate how plants might use molecular mathematics to regulate the rate at which they devour starch reserves to provide energy throughout the night, when energy from the Sun is off the menu1.
Portals. Flora. Plant Mind. World Flora Online. The New York Botanical Garden (NYBG) is one of four prominent international botanical organizations leading the effort to forge the WFO, along with the Missouri Botanical Garden, the Royal Botanic Gardens-Kew, and the Royal Botanic Gardens-Edinburgh.
An additional 30 research institutions from many of the world's most biologically diverse countries, including Brazil, China, Colombia, India, Malaysia, Mexico, Russia, and Thailand, have also committed to contributing content as primary partners. Thanks to generous funding from Google and the Alfred P. Sloan Foundation, NYBG now has the resources to begin large-scale digital capture of it's plant research holdings, beginning with the extensive Flora Neotropica monographs series, published by the NYBG Press since 1967.
FloraGator - a multiple-entry key for flowering plant family identification. How plants decide that it is time to flower. When spring is approaching, how do plants decide that it is time to flower?
A team of plant scientists led by KWAK June M. at the Center for Plant Aging Research, within the Institute for Basic Science (IBS) unravelled a new mechanism to explain this seemingly easy, but actually complicated question. Their research was published in the Proceedings of the National Academy of Sciences (PNAS) on November 11, 2016.
Visionary plants - AoBBlog. Earth - How insect-eating plants persuade insects to pollinate them. Grubs gnaw roots, maggots munch fruits and caterpillars chew leaves.
In textbook food chains, animals eat plants, not the other way round. But there are plant species that break this rule – at least 600 species of them on the last count. These are the carnivorous plants, and they routinely feast on insects, spiders, worms – even potentially small mammals. Life for a carnivorous plant is challenging. They cannot very well march across the landscape in search of a meal. A study published in February 2016 shows for the first time that some carnivorous plants use smells to secure meals – validating an idea that Charles Darwin suggested 140 years ago. Archaeologists Dig Up An 800-Year-Old Pot. What They Found Inside Is Changing History! In 2008, on a dig in the First Nation’s Menominee Reservation in Wisconsin, archaeologists made a small but stunning discovery: a tiny clay pot.
Though it might not have seemed very impressive at first glimpse, this little piece of pottery was determined to be about 800 years old. And inside that pot? Something that changes how we’re looking at extinction, preservation, and food storage, as well as how humans have influenced the planet in their time on it. It’s amazing to think that a little clay pot buried in the ground 800 years ago would still be relevant today, but it’s true! 10 Plants That Could Kill You. Maps. World Themes Base Maps Plate Tectonics Map Earthquakes Map Precipitation Map Vegetation Map Climate Map. Vegetation as Seen by Suomi NPP. Images crafted from a year's worth of data collected by the Suomi NPP satellite provide a vivid depiction of worldwide vegetation. Suomi NPP, short for National Polar-orbiting Partnership, is a partnership between NASA and the National Oceanic and Atmospheric Administration.
The images show the difference between green and arid areas of Earth as seen in data from the Visible-Infrared Imager/Radiometer Suite, or VIIRS, instrument aboard Suomi NPP. VIIRS detects changes in the reflection of light, producing images that measure vegetation changes over time. Flowers get an electrifying buzz out of visiting bees. By Douglas Heaven Plants could turn out to be one of the more chatty organisms. Recent studies have shown they can communicate with a surprising range of cues. Earth - Plants talk to each other using an internet of fungus. It's an information superhighway that speeds up interactions between a large, diverse population of individuals. It allows individuals who may be widely separated to communicate and help each other out. But it also allows them to commit new forms of crime. No, we're not talking about the internet, we're talking about fungi. The Mystery Of Why Sunflowers Turn To Follow The Sun — Solved.
