Animals share needs such as eating, breathing, moving and reproducing. Yet their solutions to meeting these needs are incredibly diverse, constrained as they are by each group's evolutionary history and by the specific demands of the environment in which they live. By looking at the range of solutions animals have devised to navigate life on earth, we will explore fundamental themes in physiology including homeostasis and the relationship between structure and function.

The immune system protects the sterile interior of our bodies from the vast diversity of microbes in the outside world, adapting and improving from each encounter. How does it achieve this remarkable feat? This course will investigate the cells, organs, and biochemical signals that comprise innate and adaptive immune systems, as well as how they interact to identify and remove foreign pathogens. Emphasis will be placed on the human immune response to infectious diseases, with examples from clinical case studies and experimental models.

This field-based lab course will explore local community ecology and biodiversity using our own Mount Holyoke campus in winter as a "living lab." We will explore local community patterns in study sites, identify plant and animal species, and develop research projects that investigate ecological processes and community interactions. Students will learn basic statistical programming using the R environment to analyze collected and available data for independent or group research papers/presentations.

Invasive species have become a common focus for land managers and gardeners around the world because some invasive species have decimated local biodiversity. What can we learn about these species, their interactions with local communities, and the dynamics of invasions that will help us manage diversity in a changing world? We will discuss the science and politics behind invasive species and explore the secrets of their success their impacts. This course will include a whole class project or group research projects based on current issues in the literature or local invasive species.

Over the past quarter century, molecular genetic methods have become increasingly important in ecological research. In this course, we will examine contemporary molecular genetic tools and learn how they can be used to answer ecological questions. Topics will include: reconstruction of ancestral relationships; measuring the size, diversity, and spatial structure of populations; characterization of migration and dispersal patterns; and identification of sensitive or threatened species and populations.

What roles do ecology and evolution play in shaping where, when, and how plants are geographically distributed? In this course, we focus on this question by examining plant geographic patterns on both global and local scales. We explore how abiotic and biotic factors affect historical, present, and potential future plant distributions. Together we engage primary literature on topics such as island biogeography, climate change effects on species persistence, and contemporary influences of humans on the movement of plants.
