Mountain Lions in Northern Colorado

Mountain lion, northern Colorado, http://www.wildnaturemedia.com

In this episode, Jill Sjong interviews Wild Nature Media‘s David Neils who has been studying mountain lions and other apex predators in Colorado’s wild lands for over 20 years using remote cameras.  They visit one of the front range’s best habitats for mountain lions, the Sylvan Dale Guest Ranch, located near where the Big Thompson Canyon opens up west of Loveland. Sylvan Dale has put 70% of its land into a conservation easement.

We get answers to our mountain lion questions: what is predictable about them? What are our greatest misunderstandings about them?  What makes certain Colorado lands such an ideal habitat for them? In what ways are they remarkably different from other apex predators? How are their populations doing?  And what about the recent media coverage on mountain lions?

Listeners can learn more about mountain lions and other apex predators at Wild Nature Media, and sign up for presentations, workshops and nature hikes.

Psychedelic Mushrooms & Depression

In this How on Earth episode, we learn about the latest research on psychedelic mushrooms (psilocybin) and their potential for treating depression.   Jill Sjong speaks with Alex Kwan, a neuroscientist and Associate Professor in Psychiatry at Yale University’s School of Medicine, who studies dendritic plasticity in mice using advanced optical methods.   Dr. Kwan explains how psilocybin changes the brain, how these changes last long after the psychedelic effects have worn off, and how these results may lead to future treatments for depression.

Octopus Wild

This week we review the hit movie “My Octopus Teacher,” the story about a man who goes diving in a kelp forest off the Western Cape of South Africa, and becomes acquainted with an octopus.   We review the movie with Roger Hanlon, a diving biologist, cephalopod expert and senior scientist at the Marine Biological Laboratory in Woods Hole, MA.   We discuss the octopus’ elaborate camouflage and complex behavior.  We’ll get some answers to our octopus questions:   Do they dream?   Do they play?   Use tools?   Are octopuses a second form of intelligent life on earth?

You can learn more about the South African sea forest at the Sea Change Project.  You can learn more about octopuses at Roger Hanlon’s research.

In Part Two of the Shale Revolution, we look at the environmental concerns associated with hydraulic fracturing, particularly the air quality along the Front Range.    We interview Detlev Helmig, an atmospheric scientist, who monitors the air quality along the front range.    We also discuss why well setbacks are such a contentious issue in Colorado.

This week on How on Earth, we look at the shale industry, which has transformed this country in ways we could not have imagined a decade ago.    How did this happen?   Where do experts think the fracking industry might be going?     In this two-part series, we consider why Wall Street and environmentalists are becoming strange new allies.

We interview Paula Noonan from Colorado Watch, the platform for tracking Colorado Legislature.   We also listen to excerpts from Bethany McLean, author of Saudi America:   the Truth about Fracking and how it’s Changing the World.

The Neuroscience of Pain

Woo2017NPStuningcurve-copyChronic pain is a debilitating condition for millions of people worldwide.   But what role does our brain play in processing pain?    Cognitive neuroscientists are gaining a better understanding of how our brain processes pain.   Using advanced imaging techniques, they can now measure and model brain systems linked to our pain and emotions.   This is shedding new light on interventions for people who suffer from chronic pain.
In this How on Earth episode, Jill Sjong speaks with Tor Wager, Distinguished Professor in Neuroscience at Dartmouth College, and formerly Professor of Psychology and Neuroscience at CU Boulder.   Jill also speaks with Charlie Merrill, a Boulder-based physiotherapist and Clinical Advisor at Lin Health, a digital integrative pain clinic.   Charlie Merrill works extensively with local athletes, many of whom suffer from chronic pain.

The Corral Bluffs’ Fossil Discovery: Earth’s Comeback Story

In this episode Angele Sjong interviews Tyler Lyson, a vertebrate paleontologist at the Denver Museum of Nature and Science, about his team’s extraordinary fossil discovery at the Corral Bluffs.

When the asteroid destroyed most of life on earth 66 million years ago, including the dinosaurs, this cataclysmic event ended the Age of Reptiles and began the Age of Mammals.Paleontologists have long struggled to understand the first million years of the Age of Mammals, however.  What kinds of mammals survived this event?   When and how did mammals become big again?  When did mammals begin to diversify?  What was the plant life and climate like at this time?   The animal and plant fossils at Corral Bluffs shed light on this critical time period in earth’s history that has been a mystery for so long.

The Corral Bluffs have been featured on the PBS Nova show titled “Age of Mammals.”   Nova show, “Rise of the Mammals”.
