Window to the past
How long has Central America been so biologically diverse?
Septiembre 28, 2017
20-million-year-old fossil seeds shed light on origins of plant biodiversity in Panama.
Declining reefs
What were Caribbean coral reefs like before humans?
Septiembre 29, 2017
Fossil reefs from around the Caribbean show how biologically rich these ecosystems once were — and provide goalposts for conservationists hoping to restore them.
Maya Dog Mystery
First Evidence of Live-traded Dogs for Maya Ceremonies
Marzo 21, 2018
At one of the oldest Maya sites, STRI staff archaeologist, Ashley Sharpe, discovered dog bones from the Guatemalan highlands deep within two pyramids.
Learning from other species
Predators learn to identify prey from other predators
Marzo 21, 2018
It is much faster to learn to recognize a new prey item from a neighboring species, than to learn by trial and error.
What stops mass extinctions?
Lessons From Amphibian Die-off in Panama
Marzo 30, 2018
What slows or stops a disease epidemic if the pathogen is still present? It appears that wild frogs are becoming increasingly resistant to the chytrid fungal disease that has decimated amphibian populations around the world.
Flowers from Darkness
“Tropical forests are the result of an accident of history.” - Carlos Jaramillo.
Abril 23, 2018
About 66 million years ago, a radical change on the Earth filled tropical forests with flowers. A new catalog of fossil pollen grains may hold an explanation.
Redefining Pristine
Modern marine oxygen-deficiency research inspires search for fossil record
Mayo 11, 2018
Smithsonian scientists who documented massive mortality of corals and reef organisms meticulously studied one of the apparent causes: oxygen deficiency. A Smithsonian paleobiologist asks if the recent fossil record shows signs of similar hypoxia events.
Behavioral evolution
First report of stone tool use by Cebus Monkeys
Julio 09, 2018
White-faced capuchin monkeys in Panama’s Coiba National Park habitually use hammer and anvil stones to break hermit crab shells, snail shells, coconuts and other food items, according to visiting scientists at the Smithsonian Tropical Research Institute (STRI). This is the first report of habitual stone-tool use by Cebus monkeys.
Not Resilient
Old Species Learn New Tricks…Very Slowly
Agosto 23, 2018
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.
