BIOL 100 - Reed in Kenya: The Ecology and Evolution of Cooperation and Conflict

This multidisciplinary course is focused on the Ecology and Evolution of Cooperation and Conflict and will take place in Kenya, beginning in Nairobi, based mainly at Mpala Research Centre, and with three excursions to other areas. The evolution of cooperation and the resolution of biological conflicts present a fascinating puzzle in biology? When does it make sense to work together? When does it make sense to compete? Many different organisms demonstrate cooperative behaviors, including humans, but the conditions that favor cooperative behavior (or cheating behaviors) are an active area of research. Similarly, the conditions that lead to competitive, predatory, or defensive behaviors can be dynamic, with different pros and consÌýresulting in an array of possible conflict resolutions with contrasting outcomes for different participants. We will explore the spectrum of interactions in biology from mutualist to pathogen. This topic provides an integrative, but coherent, guiding theme around which we can explore a number of learning opportunities in Kenya, ranging from the geopolitical and national climate, interactions among humans and their environments, to behavioral ecology among different species of wildlife.

BIOL 303 - Leaves to Landscapes

This is a field experience-based course that examines the underlying structure, function, diversity, and ecology of Pacific Northwest (PNW) Forests. The heart of this course is the weekly and extended (weekend) natural history field trips that allow for exploration of our amazing native forests and the identification of all the major tree species in the PNW. These trips provide an outdoor classroom for us to discuss topics such as plant water and carbon relations, plant life history and resource use, resilience of trees and forests to disturbance, and plant responses to global change. In addition, we will explore how our forests operate as complex socio-ecological systems through direct interaction with the natural resource managers, conservationists, and decision makers who steward these lands. In the latter part of the semester, an independent course project will be undertaken that focuses on (1) building skills for testing hypotheses about the patterns and processes of trees and forests and (2) employing a translational-science approach that connects decision-makers to the scientific process. It is important to note that this is a FIELD-BASED COURSE. As often as possible, class will occur outdoors. As such, the course requires the willingness to spend considerable time in challenging and unpredictable field conditions.

Advances in Forest Canopy Research
Most research to understand the forest ecosystem has taken place from the forest floor. Yet many of the ecological and physiological processes that drive forest ecosystem function take place far above the ground in the complex intersection of branches that forms the forest canopy environment. This class will explore the history of, common techniques in, and recent advances for studying this unique and important environment through study of the academic literature and hands-on investigation of canopy access techniques, including tree climbing and canopy sampling using drone-based technology.

We will examine the mechanisms, evolution, and ecological significance of communication across species, considering how animals convey information for mating, social bonding, warning signals, and territorial defense. Through an interdisciplinary approach, we will integrate concepts from ethology, neurobiology, and evolutionary biology to understand the role of communication in survival and reproduction. Additionally, we will discuss the similarities and differences between animal communication systems and human language, including the limits of nonhuman cognition and expression. By the end of the course, students will have a comprehensive understanding of the adaptive significance and complexity of communication in the animal kingdom.

Ecological and evolutionary contexts of interactions between plants and humans. Potential topics include agricultural ecology, grazing, plant-resource extraction, crop evolution and their diseases/pests, plant breeding, transgenic species, and invasive plants.

Global Change Ecology
In light of ongoing environmental change, how are the Earth's ecological systems likely to respond? We will discuss and present primary literature related to advanced basic and applied concepts in ecology to 1) explore the theories and tools for understanding the ecological response to environmental change and 2) identify sources of uncertainty for accurately understanding such issues.

Neuroethology
Exploration of modern and classic research aimed at understanding the neural basis of behavior. Neuroethologists investigate how the brains of diverse species generate natural behaviors, with the goal of elucidating fundamental principles of brain function. Topics may include animal communication, learning and memory, locomotion, prey capture, and escape behavior.

BIOL 453 - Advanced Evolution

This lecture/conference course will focus on exploring the central, unifying tenet of biology-evolution through readings and discussion. Despite its centrality, evolution is often misunderstood. Learning objectives includeÌý1) provide an accurate and integrative understanding of evolutionary biologyÌýgenerally, 2) introduce patterns of micro- and macroevolution, as well as the use of phylogenetic analysis to understand relatedness, 3) connect biological phenomena (e.g., adaptation or horizontal transfer) to their evolutionary consequences, 4) review evolutionary theories and debates, 5) readÌýpapers from the primary literature on evolution, 6) explore human origins and evolution, 7) confront the problematic and racist roots of evolutionary biology as a field, 8) examine current-day issues related to the acceptance of evolution in society, 9) consider frontiers in evolutionary biology research (e.g., synthetic biology and de-extinction) and 10) discuss the relevance of evolution in applied contexts. Students who have taken BIOL 273Ìýmay not take this course.

BIOL 572 - Cells and Society

This course will exploreÌýthe biochemisty, cell biology, neurobiology,Ìýand the societal impacts of the opioid receptor. We will track how a receptor is made, how it is transported in the cell, and how it functions with regards to pain and sedation.ÌýWe will then disucss the origins of the opioid pandemic starting from a historical prespectiveÌýtransitioning to how it affects the ecomomy, race relations, and the society at large. In order to do so, we willÌýread primary literature pulling from cell biology/neurobiology, sociology, and economics to takingÌýa holistic, interdisciplinary approach.Ìý
