    How Lizards Find Their Way Home

    Scientists at Work

    (8 min 33 sec) When Dr. Manuel Leal removed lizards from an area in the forest, he noticed an interesting phenomenon: all the lizards seemed to be back the next day. Watch as he sets up an experiment to study how these lizards navigate home. Also available in Spanish.

  • Seed Dispersal and Habitat Fragmentation

    Seed Dispersal and Habitat Fragmentation

    Scientists at Work

    (8 min 3 sec) Watch researchers follow brown spider monkeys in a tropical forest of Colombia to determine which plant seeds they are dispersing. Seed dispersers are critical to the forest’s ability to grow and regenerate.
