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

These maps dramatically illustrate how rising sea levels completely altered the shape of Panama’s coastline, creating islands and submerging large areas of land.
Through their foraging behavior across the diverse topography of the African savanna, megaherbivores may be unknowingly influencing the growth and survival of vegetation on valleys and plateaus, while preserving steep slopes as habitat refugia.
The first time Dumas Gálvez saw the ant species Ectatomma ruidum under a microscope, he was just a little boy. He was immediately fascinated. A few decades later, as a postdoctoral fellow at the Smithsonian Tropical Research Institute (STRI), a professor in the entomology department at the University of Panama and a mentor to young scientists, he does research on that same ant species. Listen to him narrate every step of his academic journey: his experiences, mentors, mistakes and lessons learned.
The poop of Trachops cirrhosus revealed surprising results about its foraging abilities and prey preferences.
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.

Male Wrinkle-faced bats lower a flap of skin resembling a face mask when they are ready to mate according to a rare sighting of a lek of bats in Costa Rica.
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 strong relationship formed between two female adult vampire bats may have motivated one of the bats to adopt the other’s baby.
