Unearthing the prehistoric plant species of Panama
July 04, 2019
Little is known about the early flora of the isthmus. The first Panamanian paleobotanist aims to change this
The great flood
Animated maps of sea level rise: the Isthmus of Panama during the last 26,000 years
September 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?
September 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.

How the Chicxulub Impactor gave rise to modern rainforests
April 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.
Crabosaur
Unique dinosaur-era fossil bridges a gap in the evolution of crabs
October 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
Good News!
Recovery of the Juan Diaz mangroves
October 22, 2021
Over the last 50 years, since 1972, Panama has lost almost 50% of its mangroves primarily due to urban expansion and the conversion of mangroves into agricultural land.

Drones help solve tropical tree mortality mysteries
February 09, 2022
Understanding when and where trees die in vast tropical forests is a challenging first step toward understanding carbon dynamics and climate change. Researchers explained variations in tree mortality over a five-year period by analyzing drone images of one of the most-studied tropical forests in the world, Barro Colorado Island in Panama.
