Native Species Reforestation
Smithsonian releases guide to restoring tropical forests
October 28, 2016
Drawing on 30-plus years of research in the Panama Canal Watershed, Smithsonian scientist Jefferson Hall releases an illustrated publication that will improve reforestation and help successfully restore forests with 64 species of Neotropical trees.
Window to the past
How long has Central America been so biologically diverse?
September 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?
September 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.
This Year on Earth Day
Free Online Tree-Planting Guides
April 19, 2018
Now that the rainy season has started, it is the perfect time to plant trees in Panama. We offer smart, science-based advice for choosing the perfect trees for your site and helping them to grow.
Flowers from Darkness
“Tropical forests are the result of an accident of history.” - Carlos Jaramillo.
April 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
May 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.
Reducing our carbon footprint
In STRI’s carbon offset program, everyone wins
June 27, 2018
STRI took a gamble on a carbon offset program in partnership with an indigenous community in eastern Panama. Ten years later, it has successfully met offset goals, empowered women, built environmental stewardship capacity, created a long-term research platform and offered hope for a community’s threatened forest-based traditions.
Unique strategies
Each tropical tree species gets the nutrients it needs
August 06, 2018
Biodiversity is the key to successful reforestation and climate-change mitigation because each tree species has its own way of getting the nutrients it needs to survive.
Not Resilient
Old Species Learn New Tricks…Very Slowly
August 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.
