The short, straight bills of male purple-throated caribs and the long, curved bills of female caribs correspond to the shape of heliconia flowers on which they feed. The story got more complicated, though, when Dr. Temeles and his students discovered that despite their curved bills, females prefer straight flowers to curved ones. Join us as Dr. Temeles explains how this species’ sexual dimorphism evolved, and read more in his paper in the May issue of Ecology.

In this edition of Field Talk, we catch up with Tracy Langkilde, assistant professor of biology at Penn State University, who studies one of the ants’ seemingly unlikely targets: eastern fence lizards. The lizards have evolved a novel twitching response that flicks attacking ants off their bodies. But in her paper in the January issue of Ecology, Dr. Langkilde explains that since native ants don’t normally attack lizards, this behavior must have evolved in a very short time.
