Big Trees, Masks And Singing, Capturing Holiday Scents, Unseen Body. Dec 17, 2021, Part 2
Big Trees, Big Benefits
When you think about big trees, likely what comes to mind are some of the Earth’s biggest trees, like giant sequoias or redwoods, which can grow to roughly 25 stories tall. But big trees are actually an essential part of every forest ecosystem.
Big trees capture a disproportionate share of carbon, provide important animal habitats, propel new tree growth and provide much needed shade. The largest one percent of trees or those which measure roughly 2 feet or larger in diameter are considered the big trees of any forest.
Jim Lutz, an associate professor of forest ecology at Utah State University in Logan, Utah joins guest host John Dankosky to explore the wonderful world of big trees. Lutz is also the principal investigator for three forest dynamics plots in the American West through the Smithsonian network.
How To Create Your Own Holiday Scent MemoriesWhat smells do you associate with the winter holiday season? Maybe it’s woodsmoke, cinnamon, or the ubiquitous scent of pine. Whatever fragrances you find festive, chances are good they’re strongly tied to memories of holidays past.
Science educator Jennifer Powers returns to explain this enduring connection between scent and memory in the brain. She walks guest host John Dankosky through how to capture custom combinations of memorable holiday scents in your home this season.
