Seductive Frogs and Sexual Selection

In this video, we take a brief look at one of the ways that Darwin's theory of sexual selection plays out. Male túngara frogs, as biologist Mike Ryan has shown in pathbreaking experiments, can make themselves more attractive to females by making more complex calls. They also, as the video demonstrates, make themselves more vulnerable to the predati...

On the Perilous Serenades of Túngara Frogs

Biologist Mike Ryan is being honored this month by the American Society of Naturalists with the E.O. Wilson Naturalist Award for his work in animal behavior.

Biologist Searches for the Genetic Building Blocks of Social Behavior Across Species

For Hans Hofmann, the quest for the genetic building blocks of human behavior begins with a small fish.

Catching Evolution in Action

Our oceans are getting warmer and more acidic every year, and as a result, coral reefs are rapidly dying. Biologist Mikhail Matz has been carefully monitoring this decline, awaiting evolutionary developments that may signal bette...Natural fluorescence of Acropora millepora, viewed under a dissecting microscope.

Ants Hibernating in a Coat of Fungus

In this week’s installment of Raw Science, we link to recent papers in the fields of biochemistry, epigenetics, integrative biology, and human ecology. Ants Hibernating in a Coat of Fungus Biologists describe describe the peculiar fungus-coating behavior of the attine ant Mycetosoritis clorindae, where hibernating workers become enveloped in a l...

Darwin Stands Tall in Texas!

David Hillis and two other Texans were named 2010 "Friends of Darwin" by the National Center for Science Education for their decades of defending and promoting evolution. Read the full article.vvvvvvv

Coastal Birds Decline on Mustang Island

Tony Amos’s almost daily bird counts over the years have revealed a troubling decline in 10 of the 28 most common species of Mustang Island’s coastal birds.

Essay: Where the wild things were

We’re entering an age of vanishing wilderness, when the wild places were. To have any hope of preserving our biodiversity in the face of climate change, we need to be futurists, pragmatic but farsighted. It is time for radical notions. One such notion is to transplant species that otherwise have no hope.

Office Hours: George Pollak's Big Idea

For more than 35 years, neurobiologist George Pollak has been using echolocating bats to study the mammalian auditory system, trying to understand how the auditory system processes communication signals and how animals are able to associate a sound with its location in space. He’s done groundbreaking work in, among other areas, decoding the meaning...

Pathogens, Parasitic Flies the Subjects of New Research for Fire Ant Control

Funding from Kleberg and Bass Foundations will help biologists look for more methods of fire ant control.

Globetrotting: Gathering Plankton in the Shadow of the Sydney Skyline

Erin Elbel, an honors biology major in the college, sends us a postcard from Sydney, Australia, where she's spending a semester abroad.

Fish-Watchers Wanted

Search the Eureka! database, which was created to help students find the right research opportunities, and you’ll find two openings posted by Ryan Wong, a graduate student in the labs of biologists Dr. Hans Hoffman and Dr. Molly Cummings: “Learning and Memory in Fish,” and “Male Interaction Effect on Female Choice in Fish.” The projects, which

Globetrotting: Asexual Ants in Brazil

Graduate student Christian Rabeling excavates fungus-farming ant colonies in Brazil as part of his doctoral research on the evolution and ecology of the fascinating creatures. Over two meters deep in this hole in Brasília, Brazil, graduate student Christian Rabeling is carefully and delicately dissecting the underground nests of a fungus-gardening ...Christian Rabeling excavates fungus-farming ants in Brasil.
