Scott Tighe Antarctica lectureWednesday, May 1, 7:00pm – Mars Ag Center Room 201 –
From Antarctica to the International Space Station: Microbial Research in Extreme Environments

With Scott Tighe, Advanced Genomics Core, University of Vermont.

Zoom Link

The ability to perform advanced genomic techniques on samples collected from extreme environments demands high performance reagents and techniques not commonly used in most labs today. Our research uses novel DNA and RNA extraction protocols, DNA-free reagents, high performance lysis enzymes, multi-step controls, high volume concentrators, and low biomass pre-amplifications to obtain high throughput metagenomic sequencing data using both Illumina-based short read sequencing and nanopore-based long read sequencing. Our procedures have been developed for samples from NASA’s ISS, Antarctica, Greenland, sulfur caves, deserts, thermophilic, halophilic, acidic, and alkaline ecosystems, as well as other common samples types including agricultural, water, food, air, soil, and forensic. This presentation will address the experimental considerations for studying each extreme location and techniques to produce metagenomics data with reduced sequencing bias.

Scott Tighe is currently senior researcher analyst at the UVM Integrative Genomics facility which handles advanced genomic analysis for the University of Vermont and associated institutes as well as several NASA locations. His expertise is all areas of genomics and microbiology including next generation sequencing, Sanger sequencing, microarray, PCR, single cell analysis, flow cytometry, metagenomics biophotonics, and biomolecular detection of ultra low biomass nucleic acids in the environment. His current research involves advancing techniques used for metagenomics and microbiome analysis through applications on extreme environments as well as sequencing microorganisms from space. He is currently Chair of the ABRF Metagenomics Research Group and Extreme Microbiome Project (XMP), co-leader of the International Metagenomics and Microbiome Standards Alliance at NIST, Board member of the Genomics Standards Consortium, and developer the NASA uTitan payload deployed to the International Space Station to study DNA extractions in zero-gravity in late 2023.

JP Cavigelli lecture on Fossil birds at Sheridan CollegeWednesday, Mar. 13, 7:00pm
Fossil Birds of Wyoming

With JP Cavigelli, Collections Manager, Tate Geological Museum at Casper College

Watch Lecture

Wyoming is well known for its vertebrate fossil deposits from dinosaurs to fishes to mammals. But what about birds? Birds are generally rare as fossils but Wyoming has produced a respectable suite of bird fossils, many of which have helped describe a pathway for the evolution of birds. This talk is a grand tour of Wyoming’s avian fossil record. And while we are at it… What is a bird?

Jean-Pierre Cavigelli (JP) has been Prep Lab Manager and Field Trip Organizer and Collections Manager at that Tate Geological Museum at Casper College since 2004.  He has been in charge of many field outings and the preparation of many fossil vertebrates from a mammoth and a T rex to micro-mammal teeth.  Before this he spent two years as Collections Manager at the University of Wyoming where he designed the database he still uses.  JP has also been doing freelance fossil preparation in his private lab for private collectors and academic paleontologists.  He has had the good fortune of having been invited to join paleontological expeditions to Mongolia, Niger, Tanzania, Alaska and North Dakota.  When he is not involved with fossils JP enjoys birdwatching, traveling, and hanging out with his supercalifragilisticexpialidocious wife (and has recently hung up his skates after a 30-year hockey career).

Brian Mutch falconer with Aplomado falconWednesday, Feb. 7, 7:00pm
Recovering the Aplomado Falcon within the U.S.

With Brian Mutch, Director, Aplomado Recovery Program
The Peregrine Fund

Watch Lecture

The Northern Aplomado Falcon was extirpated throughout its’ US range by 1952. A changing habitat from grassland to invasive species and the loss of that same important habitat to agriculture is widely accepted as the cause of the falcon’s demise. In 1986 the United States Fish and Wildlife Service listed the species as endangered. The Peregrine Fund was asked if they might undertake a recovery effort, similar to that of the effort underway at the time to recover the endangered Peregrine Falcon. Captive propagation and reintroductions of Aplomado Falcons occurred from 1990 – 2013, and The Peregrine Fund was successful at re-establishing a population of Aplomado Falcons throughout their historical, Texas Gulf Coast range. However, many recovery challenges still exist before the species can be considered for delisting.

Brian was born and grew up in Missoula, MT where he also completed a Bachelor of Science degree at the University of Montana in biology. His passions were all wildlife- and wildland-oriented but the art of falconry and hunting with Peregrine Falcons and Gyrfalcons always stood out and continue today. Through falconry, Brian would eventually meet several board members and employees of The Peregrine Fund who encouraged his employment with them. Brian has worked for The Peregrine Fund for 35 years. Duties have included working on many of their species recovery efforts to include Peregrine Falcons, Harpy Eagles, Aplomado Falcons, Orange-breasted Falcons, and California Condors. He also assisted with several research projects in Central America, Mexico, and in northwest Greenland and currently serves as the Director of the Aplomado Recovery Program.

A Passon for the Seed: The History and Science of Plant Breeding

Speaker: Dr. Donna Harris, Assistant Professor, Dept of Plant Science, UW

Abstract: Plant breeding is the genetic improvement of plants to meet the needs of humans. This began when people in ancient times began the process of domesticating wild species of plants to make them easier to cultivate. The characteristics needed for the improvement of plants for human use must be clearly defined into breeding objectives. Once objectives are defined, a plant breeder creates a large population of plant materials that are genetically different from each other and begins to identify which plants best meet the breeding objectives. Then, these new improved varieties are marketed and distributed to growers. Long-term success of a breeding program often requires that new plant material is continually added to the breeding program. Current research in my lab is focused on early maturing dry beans that maintain yield and upright stature, drought tolerant field peas, and native grasses for restoration purposes on rangelands.

Biosketch: Donna Harris is an Assistant Professor at the University of Wyoming in the Department of Plant Sciences.  She is located at the Sheridan Research & Extension Center in Sheridan WY.  Her research is in the field of plant breeding and genetics where she is working on several relevant crops to Wyoming with a focus on the current and potential needs of both the producer and consumer.  Prior to beginning her position at the University of Wyoming Donna was with BASF Vegetable Seeds where she worked as a Senior Scientist in tomato prebreeding located in Acampo, CA.  In her role, she led the discovery-based research of the US tomato prebreeding program where she managed and participated in global projects to ensure a constant flow of value-added traits into commercial varieties.  She earned her PhD at the University of Georgia in Plant Breeding, Genetics, and Genomics.  For five years, between her masters and doctorate, she worked as a corn breeder in the seed industry.

Coal to Carbon Products

Speaker: Garrett Lindemann, Director of Life Sciences, RAMACO Carbon

Watch the recorded lecture

Abstract: RAMACO Carbon is leading the development of new carbon-based materials as the building blocks for the future era of carbon manufacturing. Our vision is being accomplished by utilizing the carbon in coal to manufacture building blocks such as carbon fibers and graphene. This vision is captured in our two mission statements, “No molecule left behind” and “Coal is too valuable to burn.” The carbon content of the local sub-bituminous coal is approximately 50% carbon by dry weight and contains other valuable chemicals such as Nitrogen, Phosphorous, Sulphur, Potassium, and Copper. All of the chemicals in coal can be used to manufacture higher-value products from a low-value feedstock. Viewing coal as a “Fossil Fuel” needs to be left in the past and changed to viewing coal as a “Carbon Ore.”

Fire, Climate Change and Forest Resilience in Sub-Boreal Forests

Speaker: Dr. Jed Meunier, Research Scientist, Wisconsin DNR, Madison, WI

Watch the recorded lecture

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

Watch the recorded lecture

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.

Ecotoxicology and Freshwater Stream Bioassessments

Speaker: Lora Munroe (Hosman), Faculty Sheridan College

Watch the recorded lecture

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 wadeable 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 wadeable 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

Watch the recorded lecture 

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.

Radio Telemetry of Migratory Fishes in Clear Creek and Powder River, WY.

Speaker: Gordon P. Edwards Jr., Fisheries Biologist, Sheridan, WGFD

Watch the recorded lecture

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.

Science Museum Lecture – CRISPR: The Future of Gene-Editing Technology

Speaker: Matthew Craig, Biology Faculty, Gillette College, NWCCD

Watch the recorded lecture

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.

Biosketch: Matthew Craig completed a bachelor’s degree in Wildlife Biology and a master’s degree with an emphasis in herpetology at West Texas A&M University. His Master’s work utilized radio telemetry in an ecological and behavioral study of the Cagle’s Map Turtle, a species endemic to the Guadalupe River in South Texas. Matthew went on to take additional graduate courses at the University of Oklahoma where he did research on community ecology of stream fishes with an emphasis in multispecies shoaling behavior.

Science Museum Lecture: The Hydrogen Economy – Is Wyoming Ready?

Speaker: Robert McDowell, Catalyst Consultant

Title: The Hydrogen Economy – Is Wyoming Ready?

Watch the recorded lecture

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.

Biosketch: Bob McDowell graduated with a B.S. degree from Villanova University while working in the Research & Development group of Johnson Matthey, the world’s largest automotive catalyst company.  He was part of the team that brought the first commercial Three-Way Catalyst from concept into production, and has manufactured emission control catalysts on four continents.  He currently advises a diverse set of clients working in R&D and prototyping areas, including lithium ion batteries, biofuels, precious metal recycling, and of course, emission control catalysts.

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

Watch the recorded lecture

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. His students currently work on diverse topics, including distributions of threatened bees, effects of wind farms on insects, flight and thermal physiology of bumblebees, and overwintering of native bees. 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

Watch the recorded lecture

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. An Illinois native, Matt attended college at Southern Illinois University Carbondale where he earned a BS and MS in Forestry, while concentrating in Forest Hydrology and Soil Science. As a Hydrologist with the Forest Service, Matt has served on several Burned Area Emergency Response Teams with the Forest Service, tasked with assessing the post-fire effects following a wildfire.

He has been the Forest Fire Management Officer since 2007, and was a wildlife biologist with the Forest Service beginning in 1989. He received a BS in Natural Resource Management from Colorado State University in 1991, and has been fortunate to enjoy many outdoor recreation opportunities along the way in his career.

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?

Watch the recorded lecture

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. His research on population genetics of various forest tree species such as spruce, pine and poplar has been published in many prominent scientific journals. During 2018-19, he served on a National Academy of Sciences study committee that investigated the potential for biotechnology to improve forest health. Vikram obtained his PhD in Genetics in 2013 from Texas A&M University and did postdoctoral research at USDA Forest Service and the University of Vermont before joining 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

Watch the recorded lecture

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.
