Invasion
Jaguars could prevent a not-so-great American Biotic Exchange
January 15, 2020
Urban and agricultural development and deforestation along the Mesoamerican Biological Corridor might be generating a new passageway for invasive species adapted to human disturbance.
Sick and shunned?
Even fake illness affects relationships among vampire bats
March 12, 2020
How do social interactions change in the face of illness? As humans face potential global pandemics we look to nature for examples. Close observation of another highly social animal, the vampire bat, sheds light on how interactions change—or do not change—as individuals become sick.
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.
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.
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?
Manatee lagoon
Have Antillean manatees crossed the Panama Canal?
July 13, 2022
Over half a century ago, a group of manatees from Bocas del Toro was flown into the artificial Gatun Lake to control the abundance of aquatic plants and for public health reasons. Where are they now?
Ways of knowing
Harnessing the wisdom of indigenous communities for marine conservation
April 12, 2024
By engaging directly with community members and embracing indigenous knowledge in the Bocas del Toro archipelago, a NatGeo project led by a Smithsonian scientist highlights the necessity of inclusive approaches to safeguard critical marine ecosystems and culture for future generations.
COMBINA
Teaming up to combat invasive marine species in the Tropical Eastern Pacific
May 30, 2024
A workshop in Panama City brought together scientists, policymakers, environmental managers and port officials from across the Americas to coordinate efforts in marine biosecurity.
