Ecology & Evolutionary Biology

At UC Santa Cruz, the Department of Ecology and Evolutionary Biology (EEB) is at the forefront of understanding the natural world—on land, in the sea, and across freshwater ecosystems. From the redwood forests and kelp beds of the Monterey Bay to research sites as far-flung as Mexico, Tahiti, and Australia, our students and faculty explore how life evolves, adapts, and interacts across diverse environments.

Over the past three decades, major breakthroughs in ecological theory and genetic technologies have transformed the field—and UCSC biologists have helped lead the way. Our department continues to shape how we understand and protect biodiversity, ecosystems, and environmental health in a rapidly changing world.

With small class sizes, a strong culture of faculty-student collaboration, and hands-on learning rooted in fieldwork, EEB offers a distinctive academic experience for undergraduates and graduate students alike. Our programs not only deepen students’ understanding of ecological and evolutionary science but also empower them to apply this knowledge to real-world challenges—from species conservation to climate resilience.
