Individual tree species, not forest communities, respond to changes in phosphorus levels.

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.
Charlotte Steeves studies the relationship between land use and seasonal river stream flow at STRI as part of the Agua Salud project. She has been a STRI intern since January 2018. However, her involvement with Panama goes back much further: In some ways it seems like she’s been preparing for this adventure for her whole life.
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
Fever may be less effective at repelling infections in cold-blooded creatures
Little is known about the early flora of the isthmus. The first Panamanian paleobotanist aims to change this
These maps dramatically illustrate how rising sea levels completely altered the shape of Panama’s coastline, creating islands and submerging large areas of land.
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.
The disproportionate extinction of South American mammals when the Americas collided is still evident today
