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.

Fishing exclusion zones to help manage shark populations in Pacific Panama
Diciembre 17, 2019
Researchers identify 11 potential nursery areas of locally common and migratory sharks, which could help support shark conservation efforts in Panama and the region.
A Fearless jewel
NOT a Bird Dropping
Enero 24, 2020
The discerning eye of staff scientist, Annette Aiello, observed the fearless behavior of an iridescent insect resembling a bird dropping containing embedded, blue seeds.

Olive ridley turtles avoid unfavorable conditions
Enero 30, 2020
The nomadic nature of these marine turtles allows them to adapt to dynamic environmental factors, but presents a conservation challenge that STRI researchers hope to resolve
Swimming on microplastics
Microplastics are new homes for microbes in the Caribbean
Febrero 19, 2020
Only about 1% of marine plastic debris is recovered at the ocean’s surface, meaning the other 99% likely either sinks or is consumed by marine organisms
All the fish in the sea?
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.
Too Close
Humpback whales may risk collision with vessels in the Magellan Strait
Mayo 26, 2020
By tagging and tracking migrating humpback whales that feed in the Magellan Strait in Chile, the scientists were able to provide policy recommendations to reduce the risk of collisions
Old Genes, New Traits
Recycling old genes to get new traits – How social behavior evolves in bees
Junio 10, 2020
Researchers learned from some unusual sweat bee species on Barro Colorado Island, Panama, how the sophisticated division of labor in highly complex insect societies can arise from humble beginnings.
Insect societies
Can social bees and ants teach us the pillars of sustainable societies?
Junio 18, 2020
STRI staff scientist and evolutionary biologist Bill Wcislo discusses the foibles of social bees and farming ants and the evolution of their behavior in changing environments. In a time of crisis, what can we learn from these insects about their highly efficient public health care systems?
