This webpage, created by the Ecological Society of America, is a digital library that is composed of online educational resources. The resources are peer-reviewed for use in undergraduate ecology education. Resources are divided into three Discipline Specific Core Concepts: Botanical Core Concepts, Ecological Core Concepts, and Evolution Core Concepts. New resources are featured on the homepage. While resource descriptions are available, visitors to the website must create a free account in order to access the resources themselves.
