Biodiversity is better
Biodiversity may limit invasions: Lessons from lizards on Panama Canal Islands
Agosto 10, 2020
Lizards transplanted from the mainland to small islands in Lake Gatun, Panama, took their parasitic mites with them. What happened next provides great experimental evidence for the enemy release hypothesis.
The great flood
Animated maps of sea level rise: the Isthmus of Panama during the last 26,000 years
Septiembre 11, 2020
These maps dramatically illustrate how rising sea levels completely altered the shape of Panama’s coastline, creating islands and submerging large areas of land.
Hungry megaherbivores
How do Giraffes and Elephants alter the african savanna landscape?
Septiembre 15, 2020
Through their foraging behavior across the diverse topography of the African savanna, megaherbivores may be unknowingly influencing the growth and survival of vegetation on valleys and plateaus, while preserving steep slopes as habitat refugia.
Canal grass
Smithsonian scientist clears up Panamanian urban legend
Noviembre 30, 2020
How did canal grass arrive in Panama? STRI staff scientist Kristin Saltonstall compared the DNA of sugar cane relatives from around the world to find out.
Flowers!
How the Chicxulub Impactor gave rise to modern rainforests
Abril 01, 2021
About 66 million years ago, a huge asteroid crashed into what is now the Yucatan, plunging the Earth into darkness. The impact transformed tropical rainforests, giving rise to the reign of flowers.
Invasion dynamics
Biologists discover that more intense predation in the tropics can limit marine invasions
Junio 23, 2021
What makes a successful invasion? What keeps invaders out? Are some geographic locations more vulnerable to invasion than others?
Crabosaur
Unique dinosaur-era fossil bridges a gap in the evolution of crabs
Octubre 21, 2021
The oldest and most complete fossil crab ever discovered suggests that these animals ventured onto land at least 25 to 50 million years earlier than previously thought
A rocky start
Unique agates on a Panamanian island reveal submarine volcanic activity
Mayo 05, 2022
Giant agates found in an island on the Pacific coast of Panama prompted a study on the area’s geology to answer the question of how the Isthmus evolved and became a bridge between two continents.
Boooooooommm!
Volcanic Evolution of Panama
Julio 04, 2022
Panama is a land of volcanoes, with a long history of volcanic activity.
