  • Drylands: The Dark Horse of Carbon Cycling

    Drylands: The Dark Horse of Carbon Cycling
    2025/12/02
    Drylands play a critical role in global ecosystems as well as the carbon cycle. We talk with ecologist Brooke Osborne about the fascinating world of biogeochemistry and dryland science. Covering 40% of the Earth's surface and hosting a third of the human population, heterogeneous drylands have low resource availability and therefore are highly sensitive to climatic changes. We discuss Brooke’s ongoing research into soil carbon storage and sequestration, particularly in the context of grazing practices and land management.

    Nanosaurs & Good Lore
    2025/11/04
    This show is part of a series exploring Science Moab’s School to Science Program, connecting students with scientists in the field, the lab, and beyond. In this episode, we talk with mentor Emily Lessner, paleontologist for the Bureau of Land Management, and Shadis McDaniel, a recent Grand County High School graduate. Shadis joined Emily on a couple of job shadows, both in the office and in the field.

  • The Miracle of Lichen

    The Miracle of Lichen
    2025/10/21
    A lichen is a colony of algae or cyanobacteria living interactively with fungus and bacteria in a mutual or symbiotic relationship, but for Steve Leavitt, a lichen is a  hotspot of diversity and  an indicator of ecological health. Steve is in charge of one of the largest lichen collections in North America at BYU where he teaches and directs the Life Science Museum. But most of all, Steve loves his research and being outside. We talk with Steve about how the unique factors on the Colorado Plateau contribute to diverse lichen communities, how lichens can be used as indicators of air quality, and the impacts of climate change on their distribution. Steve explains how advancements in genetics have led to a step-change in the study of lichens and the broader implications of studying lichens for understanding life on Earth.

  • Eureka at Cisco: Jurassic Mammals

    Eureka at Cisco: Jurassic Mammals
    2025/10/07
    Brian Davis, an associate professor at the University of Louisville School of Medicine, loves looking for small fossils. His research focuses on early mammals, particularly teeth, jaws, and skull parts. Brian’s most recent discovery is a mammal fossil quarry in Cisco, Utah, part of the Morrison Formation dating back to the Jurassic period. The site has yielded small animal fossils, including some potentially significant early mammals that correlate with a nearby site in Fruita, CO. We discuss the complexities of fossil excavation, preservation, and the analysis process as well as the importance of student education.

  • Dieback Dynamics

    Dieback Dynamics
    2025/09/16
    Across the Colorado Plateau, pinyon-juniper ecosystems are facing more and more stress due to increasing heat and aridity. Today we talk with Seth Munson, a plant and ecosystem ecologist with the U.S. Geological Survey Southwest Biological Science Center in Flagstaff, Arizona. Seth’s research focuses on how dryland ecosystems respond to drought, wildfire, invasive species, and land-use to assist land management decision-making. He is currently working with the National Park Service to assess the areas of dieback of pinyon-juniper woodlands in the SE Utah Parks. The research involves both ground surveys and satellite imagery to create maps detailing the intensity and recovery of dieback over time.

  • Utah's Chinle Formation: Understanding Life in the Triassic

    Utah's Chinle Formation: Understanding Life in the Triassic
    2025/09/02
    Randy Irmis, a paleontologist and curator at the Natural History Museum of Utah, discusses his research on the Chinle Formation, (Triassic, ~201 to 230 million years ago) located in southern Utah. The Chinle Formation is characterized by river and stream deposits in a semi-arid environment, and is rich in fossils including vertebrates, plants, and trace fossils. Despite the historical lack of paleontological work in Utah compared to neighboring states, recent discoveries in the Chinle have significantly increased knowledge of life in the Triassic. We talk about the process of collecting and preparing these fossils for study and exhibits at the museum and Randy emphasizes the importance of public lands and the legal and ethical procedures for fossil collection and preservation.

  • Underneath the Rivers: Stewardship of Utah's Sovereign Lands

    Underneath the Rivers: Stewardship of Utah's Sovereign Lands
    2025/08/05
    Tony Mancuso is the Sovereign Lands Program Manager for the Green and Colorado Rivers at Utah’s Department of Natural Resources (DNR). His management efforts focus on maintaining the health and navigability of waterways under state jurisdiction, including removing invasive species and restoring natural habitats. Tony talks about specific projects like the New Rapid and Gold Bar side channels aimed at enhancing fish habitats and wetland environments. He also emphasizes the importance of public education and engaging youth through programs like Science Moab. The discussion highlights the challenges, collaborative efforts, and long-term commitments required in resource conservation and management.
