  • Changing Food Webs

    Changing Food Webs
    2024/09/17
    Plants and insects are the key members of food webs because they are not only abundant and diverse, but they also provide food for many other animals higher up the food chain. We talk with Moria Robinson, Assistant Professor of Biology at Utah State University, about variations in these food webs as climate in the western U.S. dries and warms. In particular, we look at the interactions of rabbit brush and caterpillars.

  • Rock Glaciers and Water Sustainability

    Rock Glaciers and Water Sustainability
    2024/09/03
    Utah is home to over 800 rock glaciers. These masses of ice covered with rock debris are key to perennial streams and alpine biodiversity, but they are poorly understood. We talk with Scott Hotaling, Assistant Professor in the Department of Watershed Sciences at Utah State University, who is studying the rare stonefly in order to gain understanding of how alpine streams are faring as glaciers recede under a warming and drying climate.

  • Living with Volcanoes

    Living with Volcanoes
    2024/08/06
    Sunset Crater, the most recent cinder cone in the San Francisco Volcanic Field, is estimated to have erupted between A.D. 1085 and 1090. In areas where the resulting lava flows were greater than 30cm thick, people may have been forced to migrate, leaving behind long-established homesteads and agricultural fields. On the positive side, lower elevation areas with cinder fall in the range of 3-10 cm would have become more suitable for farming, due to the beneficial effects of the cinder mulch. We talk with Volcanologist Michael Ort, who, together with a team of scientists, has unraveled the timing of these events and the implications of volcanic activity for humans at the time.

  • Day at the Museum

    Day at the Museum
    2024/07/02
    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. This program began in 2021 and to date has mentored over 57 local students. In this episode, we talk with mentor Mary Langworthy, Public Programs Manager at the Moab Museum, and Klayre Humphreys, junior at Grand County High School. Mary has sponsored several day long job shadows with local students facilitated by Science Moab. Klayre spent a day at the museum with Mary in the spring of 2024 and ended up delving into the world of shark teeth which ultimately helped Moab Museum staff update and enhance their exhibit.

  • Memory In Trees

    Memory In Trees
    2024/06/04
    As photosynthesis happens, trees take in carbon from the atmosphere and store it in the form of sugars or carbohydrates. These sugars can be stored for many years in trees as a sort of “memory” and used to support their growth and metabolism during times of stress, like a drought. We talk with Drew Peltier, ecophysiologist and professor at the University of Nevada, Las Vegas. Drew’s interests and research center on understanding how climate influences tree growth in our changing environment.

  • Finding Collaboration and Trust Uncovering the Past

    Finding Collaboration and Trust Uncovering the Past
    2024/05/07
    From the perspective of an archaeologist, the physical body of an ancient person is a gift because a body is a time capsule of the past. They lived in that space and that time, and their bodies are manifestations of what was there. We talk with archaeologist Erin Baxter, teacher and Curator of Anthropology at Denver Museum of Nature and Science, about her work unraveling the ancient southwest culture and her fascination with the archaeology of death.

  • Studying Growth Rates of the Humpback Chub

    Studying Growth Rates of the Humpback Chub
    2024/04/02
    The Little Colorado River (LCR) is a culturally and spiritually significant drainage for many people in the southwest. The LCR also provides sediment load to the main stem of the Colorado River for the production of sandbars downstream AND it is an important spawning ground for and home to the largest population of Humpback Chub. We talk with Phoebe Brown, river guide and researcher, about her studies that involve understanding the interactions of phosphorus and the growth rates of the Humpback Chub.

  • Restoration on the Range

    Restoration on the Range
    2024/03/19
    Rangelands are vast, natural grasslands, shrublands, woodlands, wetlands, and deserts that support grazing and browsing mammals and they are primarily natural ecosystems with native vegetation.These rangelands can become degraded by fire or improper grazing. We talk with Kari Veblen, professor of Rangeland Ecology at Utah State University about her research that focuses on the ecology and management of rangelands. Her research emphasizes multi-use landscapes, public and private, that are managed simultaneously for wildlife conservation and sustainable livestock production. The ultimate goal of her work is to inform sustainable management of rangeland ecosystems.
