As some conservationists and researchers begin to return large carnivores to areas where they once roamed, scientists intensify efforts to study the ecological roles of predators.

The University of St. Andrews behavioral ecologist studies the social structures and behaviors of whales and dolphins, recording and analyzing their acoustic communications.

The researchers who constructed the first reference genome for this critically endangered mollusk say it will assist restoration efforts.

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.

Courtesy of Genevieve Anderson If not for Nobel laureates Thomas Hunt Morgan, Eric R. Kandel, and Sydney Brenner, the notion of a general behavioral model might seem odd. Behaviors, after all, are determined by an animal's evolutionary history and ecological niche. They are often idiosyncratic, shared in detail only by closely related species. But, thanks to Morgan's research in the early 20th century, and Kandel's and Brenner's work over the past 35 years, the fly Drosophila melanogaster, t

Marine threespine sticklebacks haven't morphologically changed in an estimated 10 million years, but their freshwater offshoots show no signs of slowing down. These 5-cm-long, freshwater fish have undergone a recent evolutionary change, variably losing their calcified body armor and retractable pelvic and dorsal spines. Remarkably, isolated marine and freshwater sticklebacks can be hybridized in the laboratory, a fact that is allowing researchers to analyze the genetics behind their natural dive

In the planet’s warming and acidifying oceans, species from corals to lobsters and fish are succumbing to pathogenic infection.

Sexual selection doesn’t end when females choose a mate. Females and males of many animal species employ an array of tactics to stack the deck in their reproductive favor.

As the school year commences, returning scientists are again applying for grants, awards, and other financial support to pursue their various disciplines. But six academic scientists among the 24 recipients of this year's John D. and Catherine T. MacArthur Foundation Fellowships--popularly known as the "genius awards"--are in an extremely fortunate position: Their explorations for the next five years will extend as far as their imaginations will take them. "When the director called me up to co

Scientists are using video games to tap the collective intelligence of people around the world, while doctors and educators are turning to games to treat and teach.
