Title:  Democracy, the Worst Form of Government*

Presenter:  Dr. Aaron Montgomery, CWU Department of Mathematics  

Dr. Montgomery will discuss different methods of voting and how effectively these methods meet standards of fairness.  In particular, what Arrow’s Theorem means for the idea of the “will of the people” in a democratic election.  And, since there are always questions about the electoral college in election years, he will spend a few minutes discussing how the electoral college process impacts the fairness of US elections.

*except for all those other forms that have been tried from time to time...

Dr. Montgomery was on track to receive a philosophy and mathematics degree at Pomona College until he discovered that the last philosophy course required met at 8 am in the morning at the other end of the campus from his dorm room. He received his BA in Mathematics from Pomona College, and his PhD in Mathematics (with a minor in philosophy) from University of Wisconsin-Madison. After receiving his degree, he taught at Purdue University - North Central for three years and then came Central Washington University where he has taught in the Mathematics Department for the past 19 years. In addition to his mathematics teaching, he has taught a variety of courses for the Douglas Honors College, including a course on game theory and political philosophy. He is currently exploring the mathematics of modern board games.

"Tropical Biodiversity Genomics"

Speaker:  Adam Leaché
Professor, Department of Biology
Curator of Genetic Resources & Herpetology, Burke Museum of Natural History and Culture
University of Washington, Seattle

Pre-Seminar Reception:  3:30-4:00pm in Science Foyer

Natural Science Seminar 4:00-5:00pm in Science 147

Understanding the processes that promote population and species diversification is important for describing the composition of biodiversity, interpreting how ecosystems and biomes develop over time, and guiding decisions on how to preserve threatened biotas. The tropical rainforests of West and Central Africa contain spectacular species richness and endemism, yet the factors responsible for generating this diversity are understudied. This collaborative project compares diversification patterns across 20+ species of frogs, lizards, snakes, and crocodiles that are endemic to the Guinean and Congo forests. We use genomic methods to discover and describe species (systematics), model population dynamics through time (historical demography), and determine how these diverse communities evolved (comparative phylogeography). We are also developing new tools and techniques for accelerating the pace of biodiversity discovery using genomic data, including new methods to delimit species and new phylogenetic approaches to test whether populations share the same divergence times and demographic trajectories.

Everyone is welcome to attend!

Screening of I-90 Wildlife Project Documentary Film, Cascade Crossroads.

Cascade Crossroads is a 30-minute documentary film chronicling the amazing story unfolding on Interstate 90 just east of Snoqualmie Pass in Washington’s Cascade mountains, where the intersection of a vital east-west transportation corridor and a north-south wildlife corridor resulted in historic conservation, collaboration, and innovation that led to the I-90 Snoqualmie Pass East Project under construction today.

Commissioned by the I-90 Wildlife Bridges Coalition, the film aims to not only share this unique story but also inspire action in other landscapes facing similar challenges between wildlife and roads.

The film features breathtaking landscape footage of Washington’s Central Cascades and interviews with public and private partners including: Mark Anderson (Anderson Hay), Dan Brewster (Summit at Snoqualmie), Representative Judy Clibborn (D, 41st District), Gene Duvernoy (Forterra), Mitch Freidman (Conservation Northwest), Patty Garvey-Darda (Okanogan-Wenatchee National Forest), Randy Giles (WA Department of Transportation), Jon Hoekstra (Mountains to Sound Greenway), Senator Curtis King (R, 14th District), Paul James (Central Washington University), Mike Livingston (WA Department of Fish and Wildlife), Doug MacDonald (former Washington Secretary of Transportation), Charlie Raines (Sierra Club & I- 90 Wildlife Bridges Coalition), Janet Ray (AAA of Washington), Peter Singleton (PNW Research Station – US Forest Service), Jen Watkins (Conservation Northwest & I-90 Wildlife Bridges Coalition), and Brian White (WA Department of Transportation).

A trailer for the film is available at https://vimeo.com/166867310

Public release of the film is January 10, 2018. The public screening at CWU on January 26th will be the first viewing in eastern Washington. Other public screenings following the release will be listed on the project webpage.

Darwin Day Keynote Presentation: 
"Beautiful Weapons and the Diversity of Life"

*Friday--February 9th -- 5:45 to 6:45pm -- Hertz Hall Theater, Room 100
Darwin's birthday cake will be served prior to the event. *

For one special night, we are joining our Natural Science Seminar with our Darwin Day celebrations to bring you a unique study of biodiversity and evolution.  "Beautiful Weapons and the Diversity of Life" is a dance performance by the Gonzaga University Repertory Dance Company.  Discussion after the performance will be led by Dr. Brook Swanson, a comparative physiologist in the Department of Biology at Gonzaga University and Suzanne Ostersmith, Gonzaga University Dance Director.

Dr. Swanson describes the event as "...an exploration of biodiversity, examined both through research and through dance...we touch on processes of natural and sexual selection [and]...examine comparative biomechanics and the relationship between form and performance...[specifically] how interactive selective pressures lead to different solutions to life's challenges, and eventually to diversity."

Investigating Life in a Tropical Dry Forest In Jalisco, Mexico:
SOBRE Mexico Scholars Present Results of their 2017 Summer Research

Presenters:

Cameron Cupp
Samuel Gutierrez
Taylor Henne
Jennifer Magaña
Stacey Meekhof
Lilly Nava

Climate models predict tropical storms will grow stronger as global temperatures rise. The SOBRE Mexico team investigated the response of a tropical dry forest (TDF) ecosystem to Patricia, a category 5 hurricane that struck coastal Jalisco, Mexico in October 2015. In addition, the team investigated parasite/host interactions in the tropical dry forest after the storm.  By knocking down trees and snapping limbs, the storm’s strong winds altered the structure of the forest, which may in turn affect how animals use habitat.  Several techniques were implemented to monitor small vertebrates (amphibians, lizards, turtles) and some of their invertebrate parasites (ticks and kissing bugs) at Estacion de Biologia, Chamela, a TDF reserve struck directly by the hurricane.

The team will present their findings at the October 6th Natural Science Seminar, and at a national research conference in Washington DC later in October.

Friday, October 13th
A Basal Deinonychosaur from James Ross Island, Antarctica and the Biostratigraphy of the Latest Cretaceous, Antarctic Dinosaurs

Dr. Judd Case, Department of Biology, Eastern Washington University

 

Dr. Case is in his twelfth year at Eastern Washington University, having served as the Dean for the College of Science, Health & Engineering/College of STEM for almost 10 years and then as Dean of Special Projects with a major emphasis being the relationship between EWU and the University of Washington around dental and medical education.  He is now full time in the Department of Biology teaching vertebrate zoology, biogeography and hematology.  Additionally, he teaches Oral Histology & Embryology in the RIDE program for the University of Washington’s School of Dentistry and histology for the UW WWAMI Spokane medical program.

He received his Ph.D. in evolutionary biology from University of California, Riverside and his research has centered on vertebrate paleontology to answer questions in the areas of evolution, biogeography and recently on the effects of climate change on the past life in Antarctica.  Dr. Case has extensive Antarctic field experience having conducted nine field seasons in the Antarctic Peninsula, which has been funded by grants from the National Science Foundation.

Dr. Case was honored by the Scientific Committee on Antarctic Research (SCAR) as one of two professors worldwide to receive their prestigious Visiting Professor Award for 2016-17.  This past summer he took his visiting professorship at the Museo de La Plata in Argentina researching new Eocene marsupials from Antarctica as well as new end of the cretaceous dinosaurs from Antarctica.  He presented talks at the Universidad Nacional La Plata and at the Instituto Antartico Argentino in Buenos Aires.

Patterns, Sources, and Impacts of Variations and Trends in the Timing of Seasonal Transitions Over the Coterminous U.S.

Dr. Julio Betancourt, Paleoecologist, USGS

Dr. Betancourt will show how day-of-year [DOY] metrics can define spring onset in the CONUS. These DOY metrics exhibit secular trends consistent with both natural variability and greenhouse warming. In the atmosphere, spring onset variations also appear linked to the Pacific North American (PNA) pattern and the Northern Annular Mode (NAM). By contrast, last spring frost, first fall frost, and the duration of the growing season in CONUS poorly tracks common climatic indices, and instead is modulated by the polar vortex.

Seasonal timing has myriad impacts on plants and animals, biospheric processes, and human systems, and is critical for formulating adaptive responses to both climate variability and change. In the coterminous U.S. [CONUS], the timing of seasonal transitions varies widely from year to year and is also changing directionally, yet the climatic drivers, patterns, and consequences of these variations are not well understood. In his presentation, Betancourt will discuss different interpretations of large-scale drivers, opportunities for long-range forecasting, and implications for continental-scale phenological monitoring in the U.S.

Julio Betancourt is a Senior Scientist with the USGS in Reston VA, and also served for three decades as an Adjunct Professor at the University of Arizona, where he received his Ph.D. in Geosciences with a minor in Ecology & Evolutionary Biology.  He is a research hydrologist and ecologist who studies how climate variability and change affects terrestrial ecosystems at scales critical for understanding ecological and evolutionary processes and informing rational approaches to managing water and other natural resources. A Fellow of the American Geophysical Union and founding co-chair of the USGS Council of Senior Science Advisors, Dr. Betancourt has published two books and 180 peer-reviewed technical papers on a wide diversity of topics.  He has received honors from the American Water Resources Association, the Ecological Society of America and the Geological Society of America, and top awards from the U.S. Department of the Interior and the White House.  He is the founder of  USA National Phenology Network and established the Southern Arizona Buffelgrass Coordination Center, an NGO that coordinates assessment and mitigation of an African grass invasion in the Sonoran Desert.

From Bones to Behavior: Using Signs of Injury and Illness to Understand the Lives of Extinct Mammals

Meaghan Wetherell, Associate Director of Institutional Effectiveness, CWU and Adjunct Lecturer, (Ph.D., 2016, University of Oregon) Paleontology, paleopedology, CWU Department of Geology

Fossils are any sign of ancient life (bones, tracks, burrows, and even feces can become fossils), and while an animal’s behavior might not become a fossil, evidence of that behavior can. Forensic science used today can help interpret how animals interacted 30 million years ago – in a sense, like CSI: Oligocene. This presentation will discuss how evidence of illness and injury can be used to piece together a picture of herd structure, lifespan, and defense mechanisms for a group of extinct mammals called oreodonts. In particular, we will cover the abundance of bite marks, infections, bone bruises, and fractures found on the cheekbones of one genus of oreodont, and how such injuries could relate to herd behavior.

Dr. Wetherell graduated with a Ph.D. in paleontology from University of Oregon in summer of 2016, and is currently using her data analysis skills with people rather than fossils as Associate Director of Research for the Institutional Effectiveness Department here at CWU. Paleontologically her current research interests include the convergent evolution of trunks across mammalian families, geographic convergence in sympatric artiodactyls, and spatial modelling  of Pleistocene extinctions
