  • BIOL 248 Behavioral Ecology 6 credits

    Behavioral ecologists strive to understand the complex ways that ecological pressures influence the evolution of behavioral strategies. It can be argued that animals face a relatively small set of basic challenges: they must acquire food, water, and mates, and they must avoid danger. Yet we see a rich diversity of solutions to these problems. Consider foraging behavior, for example. All animals must acquire energy, but some filter particles out of sea water, others graze on nearly inedible grasses, while still others hunt in cooperative packs. In this course we will consider such topics as foraging, communication, sociality, and conflict. By focusing on the functions and evolutionary histories of behaviors, we strive to better understand the puzzle of behavioral diversity.

  • BIOL 262 Ecological Physiology 6 credits

    This course examines the physiological adaptations that allow species to inhabit a wide range of environments including polar regions, deserts, high alpine, the deep sea, and wave-swept coastal habitats. Emphasis will be placed on understanding how organisms cope with environmental extremes (e.g., temperature, low oxygen, pH, salinity and pressure) and in using metabolic theory to predict the ecological impacts of climate change (e.g., global warming, ocean acidification, hypoxia). Associated laboratory will emphasize experimentation and application of physiological concepts in living organisms.

    Ecosystem ecology involves the study of energy and material flow through systems, including both the biotic (animals, plants, microbes) and abiotic (soil, water, atmosphere) components. Topics include the major elemental cycles (carbon, nitrogen, phosphorus), patterns of energy flow, and the controls of these fluxes for different ecosystems. Current environmental issues are emphasized as case studies, including climate change, land use change, human alterations of nutrient cycles, and biodiversity effects on ecosystems.

  • BIOL 363 Seminar: Ecomechanics 6 credits

    All organisms, from Common loons to Redwood trees to Basking sharks spend much of their lives bumping up against forces associated with the non-biological world. The manner in which ecological challenges are solved (e.g., moving around vs. staying put, finding food, avoiding predators) is often related to an individual’s biomechanical design. This class will challenge students to view their physical surroundings from the perspective of an organism. How do mussels feed in a fast stream vs. stagnant pond? Why do healthy trees uproot rather than break in half? How can a sea urchin with no eyes “see”? We will use primary scientific literature to examine the physical principles that underlie fundamental ecological processes.

  • ENTS 288 Abrupt Climate Change 6 credits

    Abrupt climate change is very fast change related to “tipping points” and threshold crossings. Such change is evident in historical climate records going back millions of years. Includes interpretation of historical paleoclimate data and proxy measurement methods, evolving theories for abrupt change, the role of complex earth systems processes, and trends in global climate change today. Link to human concerns will be made by exploring several case studies on past human civilizations affected by abrupt climate change. Includes a final project on the emerging science of abrupt climate change.

  • GEOL 340 Hydrogeology: Groundwater 6 credits

    The principles of groundwater flow through the subsurface, and the functioning of aquifers. Topics include the properties of porous media, hydraulic head gradients, contaminant transport, and fractured and karstified aquifers. Labs will include working with physical sandbox models and soil columns, as well as an outdoor pumping well test (weather permitting). We will simulate groundwater flow using simple numerical modeling, beginning with an introduction to Python coding, and develop an increasingly complex groundwater model over the course of the term. No previous programming experience required.
