Our BSc Ecology and Environmental Biology course explores the diversity of the living world, across levels of biological organisation from genes to individuals, their populations and the communities they form, up to entire ecosystems.
Building on research produced in our School of Life Sciences, you will examine these concepts across terrestrial, marine and freshwater systems, examining taxa from the smallest microbes to the largest organisms on Earth.
You will investigate the crucial role of biodiversity in supporting ecosystem functions and securing the flow of ecosystem services on which humanity depends. The strong theoretical, practical and data-handling skills you develop will help you to understand how biodiversity and ecosystem functioning are changing in response to multiple interacting stressors in the Anthropocene (e.g. climate change, chemical pollution, habitat loss). You will be equipped to design management solutions to tackle current and future challenges to ecosystems and have the option to train in tropical marine biology in Indonesia, as well as environmental biology and ecology on our new Arctic field course.
