Perhaps old species, like some older people, gradually lose their ability to deal with changes in their environment. Aaron O’Dea and colleagues show that when the Caribbean was cut off from the Pacific by the rise of the Panama land bridge, evolutionarily old species took longer to expand into new habitats than evolutionarily younger species did.
Join us to celebrate a few of the discoveries made in 2018.
Why did some bee species become social, while the majority have remained solitary? On Barro Colorado Island, a bee that adopts both strategies interchangeably, may unlock the evolutionary origins of sociality in insects

Join Brazilian biologist, Bruno de Medeiros, as he explores mysterious trade-offs between plants and their pollinators and why they are important to the Brazilian economy and ecosystems.
After 14 thousand years of living in confinement and without the threat of predators, the white-faced capuchin monkeys on the Coiba National Park islands have begun to exhibit behaviors that have not been recorded in the mainland populations. For example, they are highly terrestrial and have learned to use stones as tools. Listen to doctoral student in animal behavior and former STRI fellow, Claudio Monteza, tell us this story.
Each plant produces a particular type of pollen, which means that it has unique characteristics that can be used to identify the species to which it belongs.
