Fire, Climate Change and Forest Resilience in Sub-Boreal Forests
Speaker: Dr. Jed Meunier, Research Scientist, Wisconsin DNR, Madison, WI
Abstract:In large parts of the world disturbance is a primary driver of ecosystem structure and function which influences, and is influenced by, climate change. In the western US, forest types and their associated fire regimes are predictable based on elevational gradients of temperature and precipitation. Thus, in these systems the contributions of forests as a catalyst for further climate change impacts (via emissions from wildfire or carbon sink from reforestation) are better understood. Despite the preponderance of large western wildfires in recent years, the disturbance dynamics of northern sub boreal forests have an outsized role in global climate regulation yet in many cases we lack basic understanding of disturbance patterns. This talk will highlight new research that illuminates the fire ecology in northern sub boreal forests and make general comparisons to the mountainous west, boreal, and other forests in terms of global climate regulation.
Biosketch: Jed is an ecologist and research scientist within the Wisconsin Department of Natural Resources, Division of Forestry. His research interests range from individual species attributes to landscape ecology with a unifying theme of understanding how forces of climate and disturbance drive ecological change and how we can in turn manage for resilient systems. His dissertation research was on fire ecology in northern Mexico investigating spatial and temporal aspects of fire in relation to climate and land use over several centuries. Jed received his M.S. in the wildlife ecology department at the University of Wisconsin Madison, studying the effects of hunting on
declining American woodcock populations. Jed considers himself lucky to spend his time asking questions and through applied research assisting in the management of our many treasures.

Chronic Wasting Disease
Speaker: Hank Edwards, Supervisor, Wildlife Health Lab, WGFD, Laramie
Abstract: Chronic wasting disease (CWD) is a fatal nervous system disease of cervids (the deer family) caused by an infectious protein or prion. The disease was first detected in Wyoming in 1985, and has since spread to 34 out of 37 mule deer herd units and 15 of the 36 elk herd units in the state. To date, prevalence of chronic wasting disease has exceeded 65% in mule deer and 14% in elk in some hunt areas. Not all herds are experiencing high CWD prevalence, but wildlife managers are concerned about how this disease may affect cervid populations in the future. This presentation will provide an update on what we know about CWD as a disease, in the state, and in the Sheridan Region, with time for questions at the end.
Biosketch: Hank Edwards has led the Wyoming Game and Fish Department’s Wildlife Health Laboratory (WHL) for over 25 years.

Ecotoxicology and Freshwater Stream Bioassessments
Speaker: Lora Munroe (Hosman), Faculty Sheridan College
Abstract: Ecotoxicology evaluates the effects of a toxicant on an ecosystem. Ecosystems vary in their complexity and evaluating if, or how, a system is impacted can be difficult. Freshwater aquatic ecosystems can vary according to climate, topography, soil type and size of water body, for example. In evaluating if a system is impacted, one would need to establish what the biological community in that region should look like if it were not affected and compare it to that reference condition. The EPA has developed a rapid bioassessment protocol for freshwater wadable streams to do just that in a cost
effective and time efficient manner. Sampling the biotic community and the physical parameters of an ecosystem can not only tell us if the system is impacted, but can also give some insight as to what the underlying problem may be. This presentation will discuss the use and application of EPA’s RBP for freshwater wadable streams and how biodiversity is used as a measure of health of an ecosystem.
Biosketch: Lora earned her Master’s degree in Environmental Biology at Arkansas State University in 2001 while working in an EPA certified Ecotoxicology Research facility. In eight years at the laboratory, she worked on several projects funded by the USDA, the FDA, and numerous industries across the southeastern United States. These projects varied from EPA mandated biomonitoring and assessment of freshwater streams for EPA’s 303d list, to population assessments of endangered freshwater mussels and evaluating the fate and effects of aquaculture therapeutants on receiving streams. Lora started teaching at Arkansas State University in 2006 and found her way to Wyoming as an instructor at Sheridan College in 2019.

Chemistry of the Fossils: Insight to Paleoclimate of the Kaiparowits Formation Using Stable Isotope Geochemistry
Speaker: Daigo Yamamura, Ph.D., Science Faculty, Miles Community College
Abstract: The Late Campanian-aged Kaiparowits Formation (72.5–76.6 Ma) is a thick, fossiliferous fluvio-overbank-lacustrine complex deposited in south-central Utah. Host to one of the richest, most diverse Campanian terrestrial fossil records in North America, the physical environment of the Kaiparowits ecosystem, particularly the dynamics of the hydrological system, remains obscure. Isotopic compositions of serially sampled tooth enamel phosphate (δ18Op) from tyrannosaur teeth were analyzed to see if they held data that could clarify the palaeohydrology of the Kaiparowits Formation. The δ18Ow calculated from tyrannosaur was low, suggesting that isotopically-light, high-altitude runoff strongly influenced the local hydrology of the Kaiparowits Formation. This study provides unique insight to the paleoclimate during the Campanian, and conducting similar studies in Montana and Wyoming would provide greater insight to the Cretaceous paleoclimate and paleoecology.
Biosketch: Daigo is a new Science Faculty at Miles Community College and previously taught at University of Arkansas – Fort Smith as a visiting Assistant Professor. Other professional experiences include mitigation paleontologist at SWCA Environmental Consultant and EXP. His research focus is paleoclimate and paleoecology of the Cretaceous North America, and the majority of the fieldwork takes place in Montana and Utah. Laboratory techniques employed include petrography, X-ray diffraction, scanning electron microscopy and stable isotope geochemistry. Daigo studied stable isotope geochemistry of vertebrate fossils from the Kaiparowits Formation in south-central Utah while completing his Ph.D. in Geoscience at the University of Arkansas in 2017. He plans to expand this paleoclimate investigation into Cretaceous formations in Montana and Wyoming.
Radio Telemetry of Migratory Fishes in Clear Creek and Powder River, WY.
Speaker: Gordon P. Edwards Jr., Fisheries Biologist, Sheridan, WGFD
Abstract: The Powder River and Clear Creek in north central Wyoming host an intact native fish community and the highest fish diversity in the state. Many of these fishes migrate upstream from as far away as the Yellowstone River in Montana, assisted by fish passage improvements at man made barriers. In 2021, Wyoming Game and Fish Department Fisheries Biologists began studying movements of Shovelnose Sturgeon, Sauger, and Goldeye with radio telemetry. These fishes demonstrated seasonal movements throughout the entire basin dependent upon connections among distant habitats and influenced by stream flow. A new passage structure at a dam on lower Clear Creek has restored access for many fishes to much of the creek after nearly 100 years of inhibited upstream migrations. Exciting changes to the fish community are expected to begin in 2022, when a major fish passage project is completed on the Yellowstone River in Montana.
Biosketch: Gordon P. Edwards has served the great State of Wyoming as a Fisheries Biologist with the Wyoming Game and Fish Department for 17 years, currently managing aquatic wildlife across northeast Wyoming, stationed in Sheridan. He enjoyed stints with the Department in Casper working on the fish management and statewide research crews after a couple formative years with the Utah Division of Wildlife Resources in Ogden. Gordon studied the influences of tournaments on bass populations while completing his M.S. at the University of Connecticut. His career went full circle in 2018 when he returned to his hometown with his family where he stewards the landscapes that inspired his career.
Conflict, Cooperation and Morality: Why Are We So Divided?
Speaker: Dr. Rachel Kristiansen, Psychology Faculty, Sheridan College, NWCCD

Science Museum Lecture – CRISPR: The Future of Gene-Editing Technology
Speaker: Matthew Craig, Biology Faculty, Gillette College, NWCCD
Abstract: CRISPR is a recent biotechnology that holds great promise for treating human genetic disorders, combating acquired diseases, improving the health and productivity of our cultivated species, and even controlling pest species and disease transmission in nature. As with any amazing technology, consequences, both unintended and intended can be substantial. In this presentation, Matthew Craig will review basic principles of DNA and discuss how the CRISPR/Cas9 complex uses bacterial immune mechanisms to insert an engineered sequence of DNA into a host organism. It is a gene-drive because it does not follow classic Mendelian rules, but can amplify itself in a target host species. The amazing promise as well as the possible concerns and ethics of this technology will be explored.

Science Museum Lecture: The Hydrogen Economy – Is Wyoming Ready?
Speaker: Robert McDowell, Catalyst Consultant
Title: The Hydrogen Economy – Is Wyoming Ready?
Abstract: Wyoming and our nation are facing a transition from the fossil fuel economy which started in the mid-1700’s, to a future economy based primarily upon nuclear and renewable electricity. In order to store and transport large amounts of that electricity, an energy carrier will be needed. Hydrogen is being touted by many countries as the best alternative to be that carrier, because it is essentially pollution free. What will Wyoming need to do to adapt to the new economy and how much time do we have left to adapt? This talk will give a brief description of what the hydrogen economy may be like, as well as covering some of the issues Wyoming will face during the transition.

Science Museum Lecture Series: A Bug’s Life at Extremes
Wednesday, February 17, 2021
Speaker: Michael Dillon, Associate Professor, Dept of Zoology, UW
Title: A Bug’s Life at Extremes: How the Humble Bee Thrives from Deserts to Mountain Tops
Abstract: Native bees are crucial pollinators in agriculture and in wild ecosystems, so recently documented declines in bee populations may have dramatic and far-reaching effects. Determining the causes of these declines and how to address them requires research on the basic ecology and physiology of native bees. In this talk, I’ll discuss what we’ve learned about how bees cope with environmental and other challenges such that they can persist everywhere from the deserts of southern California to the high mountains of western China. But this remarkable adaptability has limits, forcing us to contemplate a world without the humble bee.
Biosketch: Michael Dillon is an Associate Professor in the Department of Zoology & Physiology and Director of the UW-NPS Research Station. He has studied the physiology and ecology of insects, particularly bees, for over 20 years across the Western United States, China, and Central and South America.

He recently published a Field guide to the Native Bees of Wyoming with UW colleague Lusha Tronstad aimed at engaging the public in understanding, appreciating, and protecting our native bees.
Science Museum Lecture Series: Your Local Drinking Water
Wednesday, January 27
Speaker: Matt Enger, USFS hydrologist, and Jon Warder, USFS forest fire management officer for Bighorn National Forest
Title: Your Local Drinking Water – Sheridan Municipal Watershed: Its Source, Threats, and Proposed Actions on the Bighorn National Forest
Abstract: How often do you turn on your faucet and take for granted the amazing water quality we enjoy in Sheridan? We are very fortunate! However, managers from Sheridan Area Water Supply Joint Powers Board and the Wyoming Water Development Office have recognized that the Sheridan Municipal Watershed, sourced almost entirely from lands managed by the Bighorn National Forest, is at risk. A study completed in 2019 has identified that wildfire can be a major source of sediment and other contaminants to the water supply, and that action is needed to reduce this threat. Wildfires in Colorado and Wyoming in the summer of 2020 burned many homes, but also impacted municipal watersheds. The Bighorn National Forest is proposing management actions to help reduce this threat. Join U.S. Forest Service employees Matt Enger and Jon Warder to learn about this invaluable resource and the potential ramifications of wildfire, and learn about ways to provide input to the proposed actions on your National Forest.
Biosketch: Matt Enger is a Hydrologist who has been with the Bighorn National Forest since 2016.

Wednesday, December 9, 2020 – 7pm
Speaker: Vikram E. Chhatre, Research Scientist, Dept of Molecular Biology, UW
Title: Can We Save North American Forests from the Effects of Climate Warming?
Abstract: Ecosystems thrive when environmental conditions are right. Health of natural forests is inherently linked to the health of the ecosystems in which they reside. Rapidly warming climate over the last several decades has led to disruption of this balance due to emergence of novel pests and diseases. These insect and fungal species have devastated and decimated many natural forests all over North America.
With global temperatures projected to rise significantly by 2050, many forest tree species once adapted to their local environments will become maladapted. How are forest biologists and practitioners thinking about these issues with the goal of preserving our forests for the future? The speaker will discuss magnitude of the problem, and various strategies scientists are employing in this endeavor. The speaker will also provide a list of further reading materials for those interested in learning more on this important subject.
Biosketch: Vikram Chhatre is a forest tree geneticist and is currently working as a research scientist in bioinformatics at the University of Wyoming.

Indigenous Time-Keeping Depicted in Medicine Wheel and Rock Art/Science Technologies in North Central WY
Wednesday, Nov. 18th
Speaker: Ivy Merriot, PhD, Executive Director, Sky Traditions Research and Publishing
Abstract: How do we track time? Join medicine wheel researcher and scholar Dr. Ivy Merriot on a journey exploring how ancient peoples observed and interacted with time as recorded in the stones of the Bighorn Medicine Wheel and the petroglyphs of Medicine Lodge Archaeological Site.
Time is based on Earth’s relationship to the rest of the universe, yet even today’s advanced computers have not perfected timekeeping technology. The time and date we use on our smartphones is not real; it is an arbitrary, cultural construct, disconnected from the real universe we live in.
To know and track time as the earth moves through changing cycles, we need a sophisticated technology that is not vulnerable to solar flares, EMP generators, or arbitrary changes by governments. Our ancient ancestors used such a technology. They scribed time into the designs etched in rock and created markers by the placement of stones. Their connection to the landscape and its interaction with the sky and visible universe shaped an accurate method of keeping time.
In the Bighorn Mountains, not far from Sheridan, Wyoming, the high altitude Bighorn Medicine Wheel gives evidence of multi-millennial time-keeping. Fifty miles to the south at a far lower altitude, pecked petroglyphs at Medicine Lodge Creek interact with Sky Beings and Shadow Beings, enabling humans to understand and keep track of our scientific relation to the Sun and Moon, the source of time for humans.
About the Presenter: Ivy Merriot is the Executive Director of Sky Traditions, a non-profit organization focused on exploring humans’ relationship to the sky. She is an archaeoastronomer who studies stone circles and rock art, conducting research in Montana, Wyoming, Peru, New York, Scotland, England, and Africa. She is the author of the book Star Circle: The Bighorn Medicine Wheel, her dissertation: Exploratory Research of the Big Horn Medicine Wheel: Acting as an Indigenous Place-Based Pedagogical Instrument for Learning Sky-Earth Relationships, Skywatching Fundamentals and Celestial Mechanics, and the Yellowstone National Park Star Map. She is currently developing a Bighorn Medicine Wheel star map to show how the Wheel’s cairns, spokes, and rim keep track of celestial time.
This lecture is free and open to the public.
