Nine articles explore impacts of ancient human societies on tropical ecosystems, revealing the importance of incorporating the paleosciences, social sciences and Indigenous traditional knowledge to solve contemporary environmental challenges.

Coral reefs in the Tropical Eastern Pacific (TEP) are exposed to a broad range of environmental conditions defined by the upwelling of cold, nutrient-rich water from the deep ocean. Regional variation in upwelling activity along the TEP make it an ideal natural laboratory to understand the importance of changing environmental conditions for reef health and resiliency. Watch Panamanian scientist Andrew Sellers explain the aims of the ambitious Rohr Reef Resilience (RRR) Project, and his experience in recent research expeditions to the Panamanian and Costa Rican Pacific.
