In this Click & Learn, students explore factors that contribute to patterns seen in the Keeling Curve: a continuous record of atmospheric CO₂ starting in 1958.

This Click & Learn shows that keystone species exist across a variety of ecosystems and can exert their influence in different ways.

This film begins with phenomena linked to climate change and then examines how Earth’s temperature is controlled, how we know it is changing, and how the current changes compare to those over the last 800,000 years.

This film explores the foundational research in the Serengeti National Park, Tanzania, that uncovered many of the ecological principles that govern how animal populations and communities are regulated.

This video case study explores whether fungicides play a role in the decline of bee populations.

This film explores the species-area relationship, a general ecological rule that describes how the number of species in a habitat changes with area, and shows how it has been applied to the conservation of protected areas.

This interactive module allows students and educators to build models that explain how the Earth system works. The Click & Learn can be used to show how Earth is affected by human activities and natural phenomena.

This interactive module allows students to collect and analyze data from a virtual river to construct biomass and energy pyramids.

This video describes how indigenous communities from the tropical rainforest of Darién, Panama, use drones to map their lands. The communities use these maps to protect their territories from outside incursions and to design sustainable land-use plans.

This interactive module explores niche partitioning, a mechanism that enables similar species of animals to coexist.

This video follows scientists studying the seeds that brown spider monkeys disperse in a tropical forest of Colombia in order to inform and improve reforestation efforts.

This interactive module connects to an online citizen science platform for identifying animals in photos collected by trail cameras in Darién and Soberanía National Parks in Panama.
