Picky eater
Invasive lionfish may be a selective predator
July 30, 2020
By evaluating the diet choices of this species in a semi-natural environment, scientists could improve predictions of how it might affect newly invaded communities

Biodiversity is better
Biodiversity may limit invasions: Lessons from lizards on Panama Canal Islands
August 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.
Enrichment
Native trees thrive in teak plantations and may protect the Panama Canal
August 12, 2020
Teak often underperforms on poor soils. By planting valuable native trees in existing teak plantations, researchers will evaluate the potential increase in timber value, biodiversity value and ecosystem services provided.
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.
Canal grass
Smithsonian scientist clears up Panamanian urban legend
November 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.
Reducing uncertainty
Smithsonian scientists reduce uncertainty in forest carbon storage calculations
January 11, 2021
Helene Muller-Landau, staff scientist, was invited to write an authoritative review about carbon storage in forests. Her team combed through existing studies and came up with some novel conclusions of their own.

The ecological effects of lightning in a tropical forest
March 02, 2021
Lightning is common in the tropics, but its ecological effects in tropical forests are poorly understood. Steve Yanoviak, STRI research associate and professor at the University of Louisville, will summarize the basic physics of lightning, how we study lightning in Panama and the importance of lightning as an agent of tropical tree mortality.
Mysterious living monuments
How will the biggest tropical trees respond to climate change?
March 30, 2021
Scientists think that climate change may have greater impact the largest trees in tropical forests, and the death of these giants has a major impact on the forest, but because these monumental trees are few and far between, almost nothing is known about what causes them to die.
Fortuna
Jim Dalling: Revealing the secrets of a montane forest
June 08, 2021
The Fortuna Forest Reserve in western Panama hosts some of the most diverse montane forests in Central America. Jim Dalling, STRI Research Associate, will discuss the results of 25 years of research on Fortuna's climate, geology, soils and major plant groups, including more than 800 species of trees, 300 species of ferns and 200 species of orchids.
Invasion dynamics
Biologists discover that more intense predation in the tropics can limit marine invasions
June 23, 2021
What makes a successful invasion? What keeps invaders out? Are some geographic locations more vulnerable to invasion than others?
