This video follows scientists working in Gorongosa National Park as they try to determine the genes responsible for tusk development in elephants.

This video follows an international team of researchers as they collect data to map migratory bird populations in the US and Mexico.

In this video, ecologist Tony Sinclair takes us through the steps of how he uncovered that the eradication of an infectious disease in cattle led to a boom in the Serengeti’s buffalo and wildebeest numbers.

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 video describes the research of Dr. Manuel Leal, who is studying territorial lizards to understand how they navigate the dense forests of Puerto Rico to find their way to their home trees.

In this video, ecologist Brian Silliman explains how he uses manipulative field experiments to study salt marsh ecosystems. His approach revealed that these systems are under top-down control from consumers and predators.

This video follows ecologist Mary Power, who is studying the Eel River in Northern California to decipher the connection between river flows and biodiversity.

This video follows ecologist Caitlin O'Connell-Rodwell, who is studying how elephants can communicate over long distances using low-frequency sounds that travel both in the air and through the ground.

This video follows graduate student Jeremy Hemberger as he explains his experimental design for a study on the foraging behavior of bumble bees in different habitats.

In this video, entomologist Shawn Steffan describes an experiment designed to study the effect of fungicides on bumble bee colonies.

This video follows Joyce Poole and other scientists working in Gorongosa National Park, Mozambique, who made the observation that many female elephants lack tusks.

This video follows the work of scientists conducting the first census of African savanna elephants in over 40 years and the methods they are using to obtain accurate, up-to-date numbers across the continent.
