The adaptation to new diets is considered a major evolutionary driver of anatomical, behavioral and species diversity in mammals, but few quantitative studies have tested the impact of dietary evolution on morphological and species diversification across whole mammalian Orders. Bats are an ideal system to investigate this topic because they are exceptionally diverse in terms of number of species, skull morphology, diet, and sensory modalities used to locate food. In this talk, I will present two major areas of research in my lab that have allowed us to understand the patterns and mechanisms of bat diversification: analyses of cranial macroevolution across the bat radiation, and the coevolution between fruit bats and their mutualistic plants. These studies will highlight how a combination of sensory and dietary functions shaped the evolution of bat skull diversity through the modification of intrinsic mechanisms and functional adaptation, as well as the importance of bat sensory biases as agents of evolutionary change on their food resources.

Free-living chimpanzees live in large, dynamic communities. Studies of captive chimpanzees suggest that larger social groups confer physical and psychological benefits, but attempts to form groups in captivity are complicated by another aspect of chimpanzee social behavior; namely, their intense territoriality and propensity for inter-group aggression. In this seminar, Mulcahy will discuss aspects of chimpanzee behavior that affect group formation and the ways in which we attempt to overcome them when forming social groups of rescued chimpanzees at Chimpanzee Sanctuary Northwest.
The Bawa Health Initiative (BHI) is a non-profit 501c (3) organization founded in May 2005 by Dr. Dennis Richardson of Quinnipiac University, Hamden, CT and Dr. Blaise Dondji of Yale School of Medicine, New Haven, CT. Dr. Dondji who is currently a biology professor at CWU is a native of Bawa, Cameroon. The Initiative grew out of the identified needs of the people of Bawa and surrounding villages in rural Cameroon to have safe drinking water and improved health. BHI has since carried out several public health projects including distribution of insecticide-impregnated bednets, construction and installation of bio-sand water filters, distribution of anthelminthics and HIV/AIDS prevention campaign. BHI has built and is running a primary health clinic named Sophie Awounkeu Community Health Centre in Bawa since 2017. The Centre was equipped recently with brand new 2020 Toyota Landcruiser 4WD Ambulance and a new ultrasound machine. These projects were possible because of the generosity of many in the Kittitas Valley and beyond. In this seminar, Dr. Dondji will provide details of the projects implemented, the achievements and future projects.
One of the most productive mechanisms for improving existing technology or developing entirely new technologies is to incorporate novel materials with ground-breaking properties. What kinds of materials are well-suited to drive the technological innovations of the future? Many will be correlated electron materials that boast “super” properties such as superconductivity, colossal magnetoresistance, colossal magnetocaloric effects, and many others. One of the dirty secrets of correlated electron materials research is that our understanding of the physics that governs such properties is surprisingly underdeveloped. Theories that both comprehensively explain correlated electron phenomena and, more importantly, predict which materials will exhibit them remain elusive. In such an environment, new correlated electron phenomena are discovered experimentally, sometimes completely by accident, by studying the properties of new materials. This materials-driven approach to discovering and understanding correlated electron properties will be discussed, including how it is used in undergraduate student research at CWU.

Humans are bombarded by thousands of dietary, chemical, and microbial exposures daily. Emergent work indicates that the gut microbiome interfaces with these exposures potentially mediating their effects on host physiology. However, we have limited insight into the mechanistic underpinnings of these interactions. In this seminar I will detail how my lab applies integrative cutting-edge molecular and statistical techniques to examine the interplay between the host, the gut microbiota, and the environment and how we aim to leverage this knowledge to promote human health.

Ever wonder what happens when a tree dies in the forest? Follow along as we track the changes in the dead tree, from fresh dead, to hard snag, to soft snag to down log, and all of the life that follows in the decaying wood. The important ecological role of dead trees is explored, particularly by way of habitat use by the many species. In fact, almost 40% of forest wildlife are somehow dependent and tied to dead wood for their survival. Ken will explore how dead trees persist in the environment, how they change with time and some of the fascinating species associated with them, particularly woodpeckers. He might even play a song!

"Lichen Population Genetics: North American Patterns of Diversity in Three Species."
Dr. Jessica Allen, Eastern Washington University
October 23, 4-5pm (This will be presented on Zoom)
Join Zoom Meeting
Abstract: Lichens are quintessential symbioses that grow in all terrestrial habitats on the planet. Though they are abundant and diverse, they are often mysterious. Population genetics and genomics tools can illuminate patterns and processes that govern how lichens move across the landscape and reproduce.
In this talk three charismatic species will be discussed: lungwort (Lobaria pulmonaria), wolf lichen (Letharia lupina), and rock gnome (Cetradonia linearis). Each species exhibits a markedly different distribution, reproductive life history, and history of human impact, resulting in some surprising genetic outcomes.
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.

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.

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

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.

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.
Presenter: Dr. Stefano Lugli, Geologist at University of Modena e Reggio Emilia, Italy.
The Modena Cathedral with its bell tower are inscribed in the UNESCO World Heritage List as prestigious examples of Medieval art. The external walls of these monuments are covered by 21 different ornamental stones coming from the destruction of the ancient Roman town, which is now buried below more than 4 m of alluvial sediments. We will explore the fascinating geoarcheology of the Roman ruins dating back to more than 2000 years ago and the medieval despoliation and construction techniques, which created an unprecedented example of spectacular geoarchitecture.
