Food Calls
Hungry bats: Listen up

Spix’s disc-winged bats shrieked when they were first shown mealworms, a new food for them. Were they alarmed, or were they communicating their excitement to their fellow bats?

A baby hummingbird hatches. But it has fluffy feathers on its back, looking just like a dangerous caterpillar. Could this be something unusual among hummingbirds?
Have you ever wondered how city life affects animals like frogs? A new study reveals that urban Túngara frog tadpoles develop faster —but end up being smaller — than tadpoles from forests, probably resulting in smaller adults. This might be an adaptation to warmer urban puddles with fewer predators or to constantly changing environmental conditions in the city.
Research in my lab focuses on change in marine ecosystems over time, from millions of years ago to the recent past and the present day. Environmental and ecological transformation of the Caribbean caused by formation of the Isthmus of Panama and global climate changes over the last 10 million...
My lab uses natural history observations, combined with experimental field and laboratory studies, to better understand the evolution of animal behavior in changing environments. Our research focuses primarily on weakly social bees and fungus-growing ants to understand how environmental,...
My research investigates ecological and evolutionary influences on variation in rainforest communities across the tropics. The overarching goal of my research is to understand broad-scale patterns in the diversity and dynamics of tropical rainforests. Understanding how the environment constrains...
My primary research interest is the ecology of tropical rainforests, plant-animal interactions and theoretical ecology. Along with Robin Foster (now at the Field Museum of Natural History in Chicago), I founded the 50-hectare forest dynamics plot on Barro Colorado Island in the Panama Canal. The...
I am interested in the evolution and the ecology of marine organisms, particularly sea urchins, but also fishes, crustaceans, and corals. I focus on the processes that give rise to new species, and I use molecular tools to reconstruct the history of populations and of genes. Typically, this...
My primary research focuses on the ecological mechanisms that structure forest communities and determine their fine- and large-scale spatial and temporal dynamics. This research spans topics as diverse as forest demography, functional traits, canopy structure and change over succession, spatial...
In our lab, we investigate sensory and cognitive mechanisms underlying animal behavior. Animals use a wide array of cues and signals to glean information about their environment. An animal’s sensory and perceptual systems filter incoming stimuli and define an animal’s Umwelt, or the...
