Nature in the News Every year, scientists around the world work hard to learn more and answer questions about our universe. What discoveries about the natural world have scientists made in the past year? We’ve selected some of our favorite discoveries about plants, animals and ecology in 2020. Create a collage and showcase these discoveries by cutting out the images and gluing them to a background or craft materials!
New Plant Species October 6, 2020 When a forestland in Switzerland was converted over 150 years into a grassland pasture for grazing livestock, the plants that lived there had to adapt. Scientists discovered a new species of bittercress, called Cardamine insueta, that had evolved for the new grassland habitat from its forest-growing “parent plants.” Image: EurekAlert.org Nutrients in Plant Droplets September 29, 2020 Have you ever seen droplets of water on the edges of leaves? This sugary, sappy liquid is produced by the leaves in a process “guttation,” and scientists have learned that this liquid is full of nutrients that feed hungry insects! Using Technology to Count Plants in the Desert December 7, 2020 Using special cameras and computer algorithms, conservation scientists were able to count every single creosote plant (Larrea tridentata) in a 135 square mile section of the Mojave Desert. They found 23 million plants!
Recreating Martian Soil October 27, 2020 Geologists are using soil sample data from the Mars rovers to recreate artificial Martian soil and learn whether it could support growing plant life. Image: NASA / JPL / Cornell University How Venus Flytraps Snap July 10, 2020 Plant scientists have known that the Venus flytrap closes up on its prey when these insect critters, like flies, brush the hairs inside the plant twice within 30 seconds. We now know that slow-moving prey, like larvae or snails, can also trigger the plant to close if they touch the hairs just once but for a longer time. Attracting Urban Bees July 15, 2020 Ecologists studying plant-pollinator interactions have learned that community gardens in cities attract similar numbers and types of pollinators as rural areas, and that other urban spaces like parks and cemeteries could also support healthy pollinators if a wide diversity of native plants are grown.
Giant Sequoia Bark June 17, 2020 How do giant sequoia trees protect themselves? We now know that the bark of these trees is made up of a complicated, insulating 3-D network of fibers that compress and return almost completely to normal after impacts like fire or falling rocks – similarly to how a pillow bounces back under the pressure of your head! Image: Bold et al. 2020 Rainfall Impact on Pine Needles September 29, 2020 Pine trees have evolved special fibers in their needle-like leaves that help protect them from heavy rain. Many other plants have round fibers, but these ones are angled and split the falling raindrops in a way that makes them gentler on the needles. This discovery could help us design better waterproof materials! Mosses Travel the Globe Using Wind November 10, 2020 Mosses are special types of plants called “bryophytes” that don’t have roots. This year, scientists compared the spread of mosses around the world with global wind patterns. They learned that the “spores”, or special seed-like structures of mosses, travel between continents by floating high above the ground in the wind.
