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.

As oceans warm and become more acidic and oxygen-poor, Smithsonian researchers asked how marine life on a Caribbean coral reef copes with changing conditions.
Bat Hormones
Male bats with high testosterone levels have large forearm crusts when females are fertile
Diciembre 17, 2020
Male Fringe-Lipped bats smear a sticky, odorous substance on their forearms. When this was discovered, researchers guessed that it might play a role in mating. Post-doctoral fellow Mariana Muñoz-Romo has confirmed that the presence and size of the forearm "crust" is, indeed correlated with other reproductive traits.

The ecological effects of lightning in a tropical forest
Marzo 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?
Marzo 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.
