Imprinting on mothers may drive speciation in poison dart frogs
Octubre 09, 2019
Imprinting on parental color may be more important than genetics when it comes to the evolution of new species.

Is evolution predictable?
Butterflies take different paths to arrive at the same color pattern
Noviembre 14, 2019
Unrelated butterflies may have the same wing patterns. These patterns warn off predators and help suitors find the right mate. But if wing patterns in each species evolved the same way, knocking out an important gene should have the same effect in both. Carolina Concha and her team discovered that knocking out the WntA gene results in different effects in co-mimics, so the two species evolved the same pattern via different pathways.

Smithsonian sleuths distinguish tropical marine habitats in Panama using eDNA
Mayo 25, 2020
One of the big questions about using DNA in seawater to make species lists is whether it comes from a specific site or has floated in from elsewhere. In this study researchers could distinguish different marine habitats using only DNA.

Two decades among the birds of Panama
Agosto 05, 2020
Between 1944 and 1966, Dr. Alexander Wetmore, a legendary ornithologist and Sixth Secretary of the Smithsonian Institution, investigated the avifauna of the Isthmus of Panama. This became the basis of his four-volume ‘The Birds of the Republic of Panama’. In this webinar, STRI anthropologist Dr. Stanley Heckadon-Moreno takes us for a historical and photographic journey across Dr. Wetmore’s expeditions in Panama, with the support of Dr. Pamela Henson, director of Institutional History at the Smithsonian Institution Archives.

Science through passion and perseverance
Agosto 17, 2020
Dr. Gina Della Togna has gone a long way in pursuing her love for animals, including amphibians, insects, and reptiles. Last year she received the L'Oreal-Unesco Prize for Women in Science, for her research in assisted reproductive techniques for endangered species, such as the golden frog. This year she was named by Forbes magazine as one of the 100 most powerful women in Central America and the Dominican Republic. Listen to the story of how she became a renowned scientist.
