How flexible are bird brains in response to hormones?
By taking on characteristics from another, younger stage in its life-cycle, this fossil crab was probably able to adapt to new conditions.
These ghostly larvae float freely in seawater, while their parents live on the sea floor and usually go undetected. Genetic studies of larvae provide clues that there are more species to be discovered
A collaborative effort at Barro Colorado island described the daily rhythm of a rare half male-half female bee
A trip to Jicarón Island during the Coiba Bioblitz led to a published bird checklist.
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.

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.
As the Earth’s surface transforms, entire ecosystems come and go. The anatomy of fossil plants growing in the Andean Altiplano region 10 million years ago calls current paleoclimate models into question, suggesting that the area was more humid than models predict.
Anthropologist Fernando Santos-Granero has pieced together the story of a change agent whose life spanned an important period in South American history in his book, Slavery and Utopia, now available in English and Spanish.
It always pays to think outside of the box. Rachel Collin decided to look further afield to find the adult form that matched a larvae from a plankton sample in Panama and was surprised by the result.
