Sick and shunned?
Even fake illness affects relationships among vampire bats
Marzo 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
Junio 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
Julio 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
Agosto 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
Octubre 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
Noviembre 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
Noviembre 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.
Kudos
Mary Jane West Eberhard receives Linnean Medal for Zoology
Junio 09, 2021
“Her unification of developmental plasticity and genetics is a huge advance in our understanding of evolution. Her decades-long work with tropical social wasps focusing on careful field observation is testimony to what a careful observer of natural history can contribute to evolutionary biology.”-the Linnean Society
Invasion dynamics
Biologists discover that more intense predation in the tropics can limit marine invasions
Junio 23, 2021
What makes a successful invasion? What keeps invaders out? Are some geographic locations more vulnerable to invasion than others?
