Podcasts about lichens

How much do you know about lichens? These incredible taxa are understudied, but today's guest is making sure they're not undervalued. “You can't look at lichens under a microscope and not become immediately obsessed,” says Dr. Erin Manzitto-Tripp. “It's an endless world of magnificent, beautiful biodiversity.”Erin works in the mountains of Colorado to describe new species of lichens along with the rest of her fantastic lab. For this paper they called not just on the power of nature, but also on the power of music. These three new species are named after the Indigo Girls, the individual members of the band and the band itself, in thanks for the many gifts Erin and others have received through their music.Erin Manzitto-Tripp's paper “The Thin Horizon of a Plan is Almost Clear: Towards a Lichen Biodiversity Inventory of the Southern Rocky Mountains, USA” is in volume 712 issue 3 of Phytotaxa. It can be found here: https://doi.org/10.11646/phytotaxa.712.3.1A transcript of this episode can be found here: Erin Manzitto-Tripp - TranscriptNew Species: Lecanora indigoana, Lepraria saliersiae, Pertusaria rayanaEpisode image credit: Erin Manzitto-TrippListen to “The Wood Song,” whose lyrics gave this paper its title: https://www.youtube.com/watch?v=x0tUkepNqiALearn about the Lichens of Great Smoky Mountains National Park: https://www.jstor.org/stable/43188704Check out Erin's Lab and their work: https://tripp-report.com/An article about these new species, with some beautiful photos: https://www.cpr.org/2025/07/24/cu-new-lichen-species-named-after-indigo-girls/And the blog post from the Indigo Girls after hearing about their new species:https://www.indigogirls.com/blog/bnjasxuusxhyfhyynob5oiko8om81aBe sure to follow New Species on Bluesky (@newspeciespodcast.bsky.social) and Instagram (@NewSpeciesPodcast) and “like” the podcast page on Facebook (www.facebook.com/NewSpeciesPodcast).Music in this podcast is "No More (Instrumental)," by HaTom (https://fanlink.to/HaTom)If you have questions or feedback about this podcast, please e-mail us at NewSpeciesPodcast@gmail.comIf you would like to support this podcast and enjoy bonus episodes, please consider doing so at https://www.patreon.com/NewSpeciesPod

Join us as we delve into the extraordinary life and enduring legacy of Father Gabriel Amorth, the Vatican's chief exorcist. Discover the man behind the myths, his profound faith, and his relentless battle against evil. Through captivating stories and insights, we explore how Father Amorth's work continues to inspire and challenge our understanding of spirituality and the unseen world. Tune in for a journey into the life of a man who dedicated his life to the service of others and the fight against darkness.

Michael Lichens discusses the remarkable life and ministry of Fr. Gabriele Amorth, the Vatican's chief exorcist for decades. Known for his bold faith, pastoral warmth, and devotion to the Virgin Mary, Fr. Amorth performed tens of thousands of exorcisms and became a leading voice on spiritual warfare. Michael highlights Amorth's humility, humor, and constant reminder that Christ has already won the battle against evil. His writings and interviews continue to guide Catholics in recognizing the reality of the devil while keeping their eyes fixed on Jesus.In this episode:

In this gripping episode of The Catholic Couple Podcast, we sit down with Michael Lichens—author, editor, and researcher at Sophia Press—to uncover powerful stories the Church rarely tells: stories of exorcisms, murder, mercy, and redemption.We dive into two unforgettable books:

This conversation explores the profound themes of forgiveness and redemption through the story of Alessandro Serenelli and Maria Goretti. It delves into Alessandro's troubled past, the tragic events surrounding Maria's death, and the extraordinary forgiveness that Maria extended to her killer, which ultimately led to Alessandro's transformation during his time in prison. The discussion emphasizes the power of mercy and the possibility of redemption, even for those who have committed grave sins.

Love to hear from you; “Send us a Text Message”We explore Father Gabriele Amorth's book "God Most Powerful," which serves as a practical handbook for spiritual warfare. Rather than becoming obsessed with evil, Father Amorth encourages us to focus on strengthening our relationship with God through prayer, sacraments, and embracing truth. The best defense against darkness isn't fear but cultivating goodness and wonder in our daily lives.The conversation takes a fascinating turn as we discuss how young people today are desperately seeking meaning in a culture that often reduces humans to mere biological accidents. As one psychiatrist observed, "Young men will crawl over broken glass to find meaning." This search becomes particularly challenging when our society distorts language and rejects fundamental realities about human nature. St. Edith Stein's profound wisdom offers guidance: "Speak the truth in love and love people in the truth. One without the other is a destructive lie."Michael also reveals how developing relationships with saints provides spiritual allies in times of darkness. His simple prayer during the worst moments—"You're God, I'm not, please help"—offers immediate relief by acknowledging the divine relationship that sustains us.Our guest Michael Lichens, author and editor with a passion for overlooked aspects of Christian history, walks us through this harrowing yet ultimately redemptive story. Purchase Link: God Most Powerful, By Fr.

What is that growing on my tree?

At the trailhead, the woods were set alight by the sunshine reflecting off the melting snow. While my boots crunched down the trail, my eyes wandered to the trees where life was starting to awaken. Lichens, mosses, and mushrooms decorated the bark in a burst of bright greens, yellows and oranges–a welcome sight against the backdrop of the forest.

More of our Lichens foray in Mary Cairncross Scenic Reserve with lichenologist Vanessa Ryan. We check out lichens under UV light, see their “battle zones” and learn about their many unique properties.

If you've spent a lot of time outdoors in New England, you've likely crossed paths with, and probably stepped on, lichens. This mysterious indicator species plays an important role at the bottom of the food chain. It also serves as habitat for other microorganisms.

The Sporopod delves into the fascinating world of lichens! We are joined by the very knowledgable amateur lichenologist Vanessa Ryan as we walk through subtropical rainforest, noticing lichens and learning about these intriguing little ecosystems.

If they only taught this in Religion classes! I promise students would be way more engaged. In these episodes we dive into the fascinating and overlooked aspects of the Catholic faith with Michael Lichens, the author of The Weird Catholic Handbook. We'll examine peculiar and intriguing elements of Catholic history, offering a refreshing perspective on the faith that combines humor, curiosity, and profound insights. These include many bizarre and extraordinary stories that have shaped Catholicism. From saints who faced mythical monsters to the eerie beauty of bone chapels, this book uncovers the spiritual and historical significance behind these oddities. With a blend of scholarly research and engaging storytelling, Lichens brings to life the unique relics, ghostly encounters, and unusual miracles that have been part of the Church's rich tapestry.

The forest canopy above us holds secrets most people never notice—miniature ecosystems thriving on tree trunks that tell profound stories about our changing world. In this eye-opening conversation with Dr. Yolanda Wiersma, professor of biology at Memorial University in Newfoundland, we venture into the fascinating realm of landscape ecology and lichen biodiversity.Dr. Wiersma introduces us to landscape ecology—a discipline studying interactions between living things and their environments at scales visible from airplane windows. From the rolling hills and forests to human developments cutting across them, these patterns shape everything living beneath the canopy. Her work bridges traditional scientific approaches with Indigenous knowledge, leading to remarkable discoveries in unexpected places.The heart of our discussion revolves around lichens—organisms far more complex than most realize. These aren't single lifeforms but miniaturized ecosystems combining fungi, algae, and sometimes bacteria from three different kingdoms. Dr. Wiersma's passion shines as she describes how these slow-growing organisms "eat the air" through photosynthesis while producing hundreds of unique chemical compounds, some with antimicrobial properties so effective that birds line their nests with them to protect vulnerable chicks.Perhaps most surprising is Dr. Wiersma's discovery of a lichen biodiversity hotspot in central Newfoundland—an area previously overlooked by scientists until a member of the Hullapoo First Nation reached out with photographs of rare specimens. This collaboration led to documenting 175 species in a region not previously known for lichen diversity, highlighting how traditional knowledge enriches scientific understanding.Whether you're a nature enthusiast, someone curious about the hidden workings of our forest ecosystems, or simply appreciate learning about overlooked wonders in our natural world, this conversation will transform how you see the trees around you. Listen now to discover the miniature worlds thriving silently above our heads and what they can teach us about our changing planet.

Michael Lichens joins Steve and Becky to explore some seemingly strange topics that are part of the Catholic experience. His book is Weird Catholic Handbook.

Today I'm delighted to be joined by Paula Whyman, author of Bad Naturalist.Inspired by Isabella Tree's Knepp estate & Douglas Tallamy's Homegrown National Park Movement, Paula set out to find a small rural escape & establish a meadow. But Mother Nature had bigger plans & Paula found herself becoming guardian to 200 acres of neglected Virginia mountaintop where invasive species were causing havoc to this important ecosystem.Despite being a self confessed terrible gardener who knew nothing about plants, Paula threw herself heart & soul into her partnership with the mountain. She has already begun to tip the balance in favour of the native plants that support the insects, birds & wildlife of the region.The lessons Paula shares remind us all, that there is no single path or categorically right option, everything requires a degree of trade-off, expecting perfection is a fools folly that leads to frustration. But if we slowly embrace nature's timelines & make peace with tackling one challenge at a time, doing the best we can with the knowledge we have, it is possible to make a difference in this world. More about PaulaPaula Whyman decided to leave her Maryland / suburban DC empty nest to find a rural getaway, maybe a small farmhouse where she could put her interest in conservation to work. With little experience in gardening or conservation, Whyman had a crazy idea to cultivate a small native meadow to provide an acre or two where wildlife could thrive & she could explore with her poodle. Then she set foot on 200 acres of old farmland atop a Virginia mountain & her dream became a reality.Paula consults with experts & gets conflicting advice on how to best restore her land. She has to fight invasive plants that expand & push toxic substances into the soil. But to her surprise, her lovely Virginia Blue Ridge mountaintop is full of life.  Native elderberries, wild bergamot & jewelweed spring up.  Lichens sprawl, bees bumble & butterflies return, songbirds call & a few plans eventually go right.BAD NATURALIST: One Woman's Ecological Education on a Wild Virginia Mountaintop, funded by the Maryland State Arts Council, author Paula Whyman explains how she cares for her mountain-sized ecological restoration challenge with a mixture of humility & humor.  She quickly discovers it's impossible to be a “good” naturalist. This is a blend of memoir, natural history, & conservation science, a chronicle of her attempts to restore retired farmland to natural habitat.  Whyman leads us on an exploration of nature and human nature. How can we learn, adapt & find patience from one season to the next? When there's no perfect option, does that mean there's no good option? In the end, Whyman's mountain is a metaphor & an inspiration for undertaking big, tangled challenges before we can possibly know what we're getting ourselves into. What matters, is taking that first step.Website: https://paulawhyman.com/bad-naturalist/Paula's Newsletter: https://paulawhyman.com/bad-naturalist-newsletter/Support the showThank you for being part of this journey with me, please Subscribe so you don't miss our future episodes, leave a review & share with friends to help these messages ripple out across the world.

Have you ever noticed the colorful growths on trees and rocks but weren't sure what they were? Lichens are all around us yet often overlooked. They play important roles in ecosystems and can even indicate air quality. Many people don't fully understand these symbiotic organisms or appreciate their significance.In this episode, you'll learn about the fascinating world of lichens from lichenologist Dr. Jessica Allen. We discuss what lichens are, their importance in nature, how they live, and how we can appreciate these miniature ecosystems all around us.

This episode: Trends of declining lichen populations and biocrust cover overall match trends of increasing temperatures in Colorado dryland! Download Episode (6.4 MB, 9.3 minutes) Show notes: Microbe of the episode: Cherry chlorotic rusty spot associated partitivirus Takeaways: Global climate change is affecting almost every natural system on the planet, in predictable and also sometimes unexpected, complex ways. Microbes perform key roles in many different ecosystems, providing and recycling important nutrients and even macroscopic structure. One example of this is biocrusts in dryland environments, such as areas in the western US with low annual rainfall. Microbes other organisms form a stable surface binding soil and sand particles together, helping to retain moisture and prevent erosion and transformation of land into desert. In this study of a Colorado park over more than 20 years, important species of symbiotic fungi and photosynthetic microbes in the form of lichens have declined significantly. The land is mostly untroubled by grazing or human activity, but changes in climate and moisture and the presence of invasive plants could affect lichens. However, the temperature increase over the decades showed the best correlation with the lichen decline. The loss of these species could lead to nutrient shortages in the long term for these communities.

James P. Gray was a trial judge in Orange County, California, starting in 1983, and the 2012 Libertarian candidate for Vice President. In the first half, he shared his views as a Libertarian, and weighed in on such issues as public education, homelessness, healthcare, taxes, and drug laws. Libertarians, he noted, believe that "you should be able to live your own life as you choose, as long as you don't wrongly impair other people to do the same thing." Now working as a private mediator in resolving disputes, he lamented that many in society have lost the ability or even interest in talking and working with each other to address and resolve issues, particularly of a political nature. One of the most critical issues facing America is that many public schools are failing our children, especially in lower economic areas, he commented. Parents should be able to choose where their government money will be spent for the education of their children, and that will bring competition back into the school systems, Gray suggested.He spoke in favor of an idea popularized by economist Milton Friedman-- negative income tax, where people who make very little or no money would receive a stipend yet would be incentivized to work rather than collect welfare. Regarding healthcare, Gray does not believe the government should be involved in implementing programs, as this has caused the medical system to be mired in costly bureaucracy. He thinks there should be vouchers for people who can't afford it, but they should choose how to use them rather than through a government vendor. Gray also discussed the problem of homelessness in cities like Los Angeles, and highlighted the need for more mental health facilities and the challenges faced by veterans in particular.-----------------With a master's degree in religion from the University of Chicago, Michael Lichens focuses his work on overlooked aspects of spiritual life. In the latter half, he discussed the Catholic Church's most celebrated exorcist, the late Father Gabriel Amorth, how he became an exorcist, and some of the intense cases he was involved with. Amorth, who was based in Rome, conducted some 70,000 exorcisms over the years, Lichens estimated, though some of these were on the same person (the documentary, The Devil and Father Amorth, depicts him performing his ninth attempt to exorcise a woman named Cristina). One of the reasons Amorth became so well-known was his willingness to work with the media, he noted. One person Amorth worked with was said to be possessed by a staggering 1,000 demons, and in some cases, he worked with individuals for years trying to free them from demons.Lichens recounted how Father Amorth was initially reluctant to be an exorcist, but after six years of training, he began to take on solo cases in the 1980s. The Church would always try to rule out natural or medical explanations before conducting an exorcism on someone. Speaking of supernatural occurrences during an exorcism, Lichens detailed how the Father witnessed levitations on occasion, as well as had a direct encounter with Lucifer and was spit upon, with the spit turning into nails as it hit him. He also experienced freezing rooms, actually seeing ice form on the windows. A spiritual protege of Amorth was Padre Pio, who bled the stigmata in his hands, battled with demons, and was said to communicate with angels. Amorth said he sometimes felt the spirit of Padre Pio (who died in 1968) assisting him in exorcisms. --- Send in a voice message: https://podcasters.spotify.com/pod/show/georgenoory/message

Today we are joined by returning guest Michael Lichens on the newly translated Amorth book, Get Behind Me Satan.  This new book dives into the daily life and work of Rome's chief exorcist, shedding light on a misunderstood vocation. In the show we get into:  How an exorcist “diagnoses” a demonic attack. The six types of demonic disturbances and how often they occur in the life of an exorcist. The strange (and sometimes occult) causes of demonic attacks. Why there is still a great need for exorcists today. You will note this is a short show the reason why will be very clear when you hear my voice!

Caterina Barbieri, Kali Malone, Moritz Von Oswald and Robert Aiki Aubrey Lowe discuss the role limitations play in the creative process, and whether they can be a source for creativity, if working with limitations helps sharpen one's aesthetics and define one's unique artistic voice, and whether human imagination needs limits to become limitless.Caterina Barbieri is a composer and modular synth artist whose sound draws from electronic, experimental and dance music. Her work is informed by an education in classical guitar and electro-acoustic composition at the Conservatory of Bologna, as well as the Royal College of Music in Stockholm and its famed centre for sound art, Elektronmusikstudion. She has spent a decade since her debut release, Vertical, breaking the rigid structures of electronic music and exploring how sound can induce both metaphysical and psycho-physical responses. Her most recent project, Myuthafoo, further investigates her interest in time, space, memory and emotion, and the links between them.Kali Malone is a composer and organist based in Stockholm. Her compositions are rich with harmonic texture through synthetic and acoustic instrumentation. In 2016 she co-founded the record label and concert series XKatedral, together with Maria W Horn, in Stockholm. Over the last few years she has released the critically acclaimed albums The Sacrificial Code, Living Torch, and Does Spring Hide Its Joy featuring Stephen O'Malley & Lucy Railton.Moritz Von Oswald is a dub techno pioneer producer and percussionist hailing from Berlin. He is the co-founder of production duo and record label Basic Channel. Prior to becoming one of the leading figures in electronic music in the 1990s, he played in one of the last incarnations of Palais Schaumburg. In a career spanning more than 30 years, he has worked with many legendary artists including Juan Atkins, Thomas Fehlmann, Carl Craig and Tony Allen. Robert Aiki Aubrey Lowe is a Brooklyn-based artist, curator, composer and multi-instrumentalist. In 1997, he joined the band 90 Day Men before releasing solo projects under the moniker Lichens from 2004. He has collaborated on projects or provided sound in a featured artist capacity for such films as End of Summer, Sicario, Arrival, Last and First Men with Johann Johannsson and It Comes at Night with Brian McOmber. More recently, Robert has scored Il colpo del cane for Fulvio Risuleo, Candyman for Nia DaCosta, The Color of Care for Yance Ford and Master for Mariama Diallo.

Scott O'Donnell is an industry name. His decades of experience guiding clients for trout and steelhead bring perspective to a career of commitment and sacrifice. It's hard work to create opportunities for clients on a daily basis. But the lifestyle has its rewards. In this episode of Fin and Fire With Jeff Mishler, I sit with Scott at my place on the Oregon Coast and we drink some whisky while sharing perspectives of how it use to be, and how it is today.  Get ready for a conversation that goes long into the night.

Nan Calvert has been contributing interesting environmentally-themed Morning Shows on a monthly basis for the past eighteen years. She recently stepped away from that responsibility. In gratitude for her great contribution to the show, we are replaying some favorite Nan Calvert shows from the past. This one is about Lichens with Kathleen Thompson.

Whenever I visit the smooth, gray rocks on the North Shore of Lake Superior, I find myself crouching low to examine the colorful patchwork of lichens who have made their home in such a seemingly perilous place. I never expected to do the same thing on Hawaii!

Did you know that urban ecology doesn't just apply to big cities and towns? Even if you live in a fairly rural area, if there is a lot of interaction between where you live and a nearby town or city then you may fall into the broad category of urban ecology. That means urban ecology is likely to apply to most of us. Today we're talking with Dr. Sarah Gagné. Sarah is the author of the newly published book, Nature at Your Door, Connecting with the Wild and Green in the Urban and Suburban Landscape. She is also an Associate Professor of Landscape Ecology at the University of North Carolina, Charlotte.

...in which we take a deep dive into the miniature world of lichens with Cumbria Lichens & Bryophytes expert Pete Martin. Embarking from the car park at Seatoller – and not wandering much further - we ask what a lichen is (a question not easily answered) and why lichens matter. Wandering up-dale towards Seathwaite, we stop at trees and walls to encounter five of the county's most recognisable lichens and observe a remarkable world of elf ears, maps, jam tarts and wine gums. Deep in the Borrowdale rainforest we consider the expansive 'second skin' lichen and bryophyte ecosystems that form on older pollarded trees, and the key role lichens play in fixing both carbon and nitrogen. Taking a long view of land use in the valley, our journey ends at the famous Borrowdale Yews, where we learn why Wordsworth's 'Fraternal Four' were never four at all, and why, in ecology, things are often more complex than they first seem.

On today's episode we are chatting with Dr. Sarah Bedell. Dr, Bedell currently practices Gynecology with her sisters and mother at New Age Women's Health in Miami FL since 2017.. She does general gynecology but also sees patients with vulvar skin conditions and conditions that can cause pain with intercourse. She went to Medical School at New York University where she met her mentor, Dr. Andrew Goldstein, who introduced her to this subspecialty. Dr. Bedell trained with him after she completed her residency at the University of Texas-Southwestern in Dallas, and worked part-time in his office in New York while primarily practicing in Miami (yes, she would commute to NYC once a month for about 1.5 years). It is through him that she actually learned about pelvic floor physical therapy.

Do you ever walk past an old building or a tree or a big rock and notice splotchy green or orange or yellow blobs growing all over it? Well, these are probably lichens! Lichens aren't plants and they aren't even technically just fungi. They are actually many organisms living together and functioning as one unit. These "composite" organisms are fungi with symbiotic algae or cyanobacteria living inside them, providing them with sugars produced by photosynthesis. On this episode, Dennis Waters explains what lichens are, why we see them everywhere, what they do, and even what they taste like! We cover topics from symbiosis, to climate change to lichens living in space, suspended outside of the International Space Station. Dr. Dennis Waters, PhD is a lichenologist and is currently a visiting scientist at the Chrysler Herbarium at Rutgers University. He is also an author and his book "Behavior and Culture in One Dimension: Sequences, Affordances, and the Evolution of Complexity" is available here or on his website.Dennis has also provided some links to resources if you want to learn more about lichens:North American Lichen ChecklistDatabase of Lichens in North American HerbariaCatalog of research papers on lichensSome helpful books: Urban Lichens (this is the one I have), Lichens of North America, Delmarva Lichens: An Illustrated Manual, Field Guide to the Lichens of Great Smoky Mountains National Park, Common Lichens of Northeastern North America, and The Macrolichens of New EnglandSome images: source 1, source 2, source 3Music is "Introducing Cosmic Space" by Elf Power and "Vorticella Dreams" by L.

A Debate Over How The Universe Began Even though it's commonly accepted today, the Big Bang theory was not always the universally accepted scientific explanation for how our universe began. In fact, the term ‘Big Bang' was coined by a prominent physicist in 1949 to mock the idea. In the middle of the 20th century, researchers in the field of cosmology had two warring theories. The one we would come to call the Big Bang suggested the universe expanded rapidly from a primordial, hot, and ultra-dense cosmos. Conversely, the so-called ‘Steady State' theory held that the universe, at any given point in time, looked roughly the same. The story of how the Big Bang became the accepted theory of physics is also a story of two men. One, Fred Hoyle, was a steady state supporter who thought the universe would last forever. Meanwhile, George Gamow, the major public advocate of the Big Bang, begged to differ. They debated in the pages of Scientific American and in competing popular books, as both dedicated scientists and earnest popularizers of their field. And while Gamow ended up winning the debate, for the most part, the two men managed to come together in one way: They accidentally explained the origins of every element of matter by being part right, and part wrong. The truth, it turned out, would lie in the middle. Ira talks to physicist and science historian Paul Halpern about this story, detailed in his book, Flashes of Creation: George Gamow, Fred Hoyle, and the Great Big Bang Debate.   The World According To Sound: Listening To Black Holes Collide In this piece, you can actually listen to gravitational waves, the ripples in spacetime made by the tremendous mass of colliding black holes. It is possible to hear them, because their wavelengths have been shifted all the way into the human range of hearing by MIT professor Scott Hughes. Drawn together by their immense gravity, nearby black holes will swirl faster and faster until they are finally absorbed completely into one another. When the pitch rises, it means the force of gravity is increasing as the black holes collide. Not all black holes come together at the same rate or release the same amount of gravitational waves, so each combining pair has its own particular sonic signature. Some black holes collide quickly. Others slowly merge. Some produce relatively high pitches, because of the intensity of the gravitational waves, while others have a low bass rumbling. Some even make the sound of a wobbling top as the two black holes swirl around each other, before eventually meeting and becoming totally absorbed into one another.   A Maggot Revolution In Modern Medicine In a bloody battle during World War I, two wounded soldiers were stranded on the battlefield in France, hidden and overlooked under some brush. Suffering femur fractures and flesh wounds around their scrotum and abdomen, they lay abandoned without water, food, or shelter for a whole week. At the time, outcomes for these kinds of wounds were poor: Patients with compound femur fractures had a 75 to 80% mortality rate. By the time the soldiers were rescued and brought to a hospital base, orthopedic surgeon William Baer expected their wounds to be festering, and their conditions fatal. But much to his surprise, neither showed any signs of fever, septicaemia, or blood poisoning.   Read more at sciencefriday.com.   Trying To Determine Forest Health? Look To The Lichens There aren't very many old-growth forest left in North America. And while it would be wonderful to be able to preserve all of them, resources to protect those forest patches are also in limited supply. So if you're forced to choose between two areas of old-growth forest, how do you prioritize which of these islands of biodiversity to focus on? One of the standard ways to identify significant patches of forest is to look at the size of the trees. But new work published this week in the journal Frontiers in Ecology and the Environment suggests that examining the lichens in a forest plot may give a better picture of the ecological health of an area. Because lichens feed from the air flowing over them, they're quite sensitive to changes in moisture, nutrients, and pollution, and need long, continuous periods undisturbed. Troy McMullin, a research scientist in lichenology at the Canadian Museum of Nature in Ottawa, Ontario, joins Ira to talk about the stories lichens can tell about the forest ecosystem.   Transcripts are available on sciencefriday.com.
