  • 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.

  • ENTS 225 Carbon and Climate 6 credits

    This course will focus on the interconnections between the Earth’s carbon cycle and climate system. Particular interest will be given to how Earth system processes involved in the carbon cycle operate on geologic timescales and how these systems are responding to anthropogenic emissions. Required weekly laboratories will explore carbon cycle processes in local environments and will include outdoor field work, lab analyses, and computer modeling.

    During registration, students will register for both the lecture and a corresponding lab section, which will appear on the student's academic transcript in a single entry.

  • ENTS 230 Remote Sensing of the Environment & Lab 6 credits

    The advancement of aerial and satellite technology has allowed humans to view the planet in a unique light. This course dives deeply into the science of remote sensing to analyze Earth's dynamic surface and atmosphere. Students will learn to acquire, interpret, and apply imagery to detect environmental change and uncover spatiotemporal patterns. Topics include sensor systems, image processing, land cover classification, and change detection. Emphasis is placed on real-world applications in environmental studies, including human-environment interactions. Labs and projects build practical skills in remote sensing software and geospatial analysis. Ideal for students in ENTS, Geology, Physics, Biology, and related fields.

  • GEOL 340 Hydrogeology: Groundwater & Lab 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.
