As bacterial infections become more resistant to antibiotics, the toxins on the skin of frogs presents huge opportunity for new drug discovery.

To save frogs from an extinction-causing fungus, Smithsonian scientists needed to innovate captive feeding and breeding techniques.
As part of the Smithsonian’s program to save frogs from an extinction-causing disease, the Punta Culebra Nature Center offers an exclusive glimpse at some of the amphibians we and our partner institutions are trying to save.
It is much faster to learn to recognize a new prey item from a neighboring species, than to learn by trial and error.
What slows or stops a disease epidemic if the pathogen is still present? It appears that wild frogs are becoming increasingly resistant to the chytrid fungal disease that has decimated amphibian populations around the world.
About 66 million years ago, a radical change on the Earth filled tropical forests with flowers. A new catalog of fossil pollen grains may hold an explanation.
Coral reef fish often see a very different seascape that humans do. Using the evolutionary laboratory created by the Isthmus of Panama, Michele Pierotti is learning exactly how they view their underwater world.
Not only does it take energy to make weapons, it may take even more energy to maintain them. Because leaf-footed bugs drop their legs, it is possible to measure how much energy they allocate to maintaining this appendage that males use to fight other males.
How do animals adapt to urban environments? In the case of the Tungara frog, city males put on a more elaborate display than males in forested areas.
Some organisms adapt more quickly than others and may have a better chance to survive climate change. 2018 Tupper Fellow, Mike Logan, follows lizards as they adapt to islands.
