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.
Male or female
How does an intersex bee behave?
March 10, 2020
A collaborative effort at Barro Colorado island described the daily rhythm of a rare half male-half female bee
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.
Old Genes, New Traits
Recycling old genes to get new traits – How social behavior evolves in bees
June 10, 2020
Researchers learned from some unusual sweat bee species on Barro Colorado Island, Panama, how the sophisticated division of labor in highly complex insect societies can arise from humble beginnings.
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.
Darwinian Diet
You are what you eat: Evolutionary lessons from agricultural ants in Panama
October 28, 2020
Just as contemporary human societies depend on large-scale agriculture, leaf-cutter ants depend on a long, co-evolved relationship with a fungus. As humans, we may share some of the same rules that govern their relationship.
Doctor crocodile
In the footsteps of crocs
November 27, 2020
Crocodiles fulfill important functions in the ecosystems where they live, and they play a prominent role in the myths and legends of cultures around the world. Miryam Venegas-Anaya will share stories about years of field work in Panama with these fascinating reptiles to increase our understanding and appreciation of their diversity and behavior.
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.
