Bats Use Water Ripples to Hunt Frogs

AUSTIN, Texas — As the male túngara frog serenades female frogs from a pond, he creates watery ripples that make him easier to target by rivals and predators such as bats, according to researchers from The University of Texas at Austin, the Smithsonian Tropical Research Institute (STRI), Leiden University and Salisbury University.

A túngara frog will stop calling if it sees a bat overhead, but ripples continue moving for several seconds after the call ceases. In the study, published this week in the journal Science, researchers found evidence that bats use echolocation — a natural form of sonar — to detect these ripples and home in on a frog. The discovery sheds light on an ongoing evolutionary arms race between frogs and bats. (more…)

Why do the faces of some primates contain so many different colors — black, blue, red, orange and white — that are mixed in all kinds of combinations and often striking patterns while other primate faces are quite plain?

UCLA biologists reported last year on the evolution of 129 primate faces in species from Central and South America. This research team now reports on the faces of 139 Old World African and Asian primate species that have been diversifying over some 25 million years. (more…)

‘Memories of Buenos Aires,’ Edited by Max Page, Maps the Terror of Argentina’s ‘Dirty War’

AMHERST, Mass. – Throughout Central and South America, there remains the palpable awareness of the decades-long “Dirty War,” in which the military and oligarchy joined forces in brutal and relentless repression of democratic institutions, and many tens of thousands people were simply marked for disappearance. That war has retained its own emotional and physical topography in the region, especially in Argentina, where as many as 30,000 citizens were killed after the generals seized power in 1976.

Now, Max Page, professor of architecture and history at the University of Massachusetts Amherst, has edited a new book that explores that topography and serves as an interpretive guide to the terror in Argentina, invoking the memory of the disappeared, the desaparecidos, in the memorials and hidden places of torture that mark the capital.

UCLA study shows warming in central China greater than most climate models indicated

Temperatures in central China are 10 to 14 degrees Fahrenheit hotter today than they were 20,000 years ago, during the last ice age, UCLA researchers report — an increase two to four times greater than many scientists previously thought.

The findings, published on May 14, 2013, in the early online edition of the journal Proceedings of the National Academy of Sciences, could help researchers develop more accurate models of past climate change and better predict such changes in the future. (more…)

Madeleine Albright Chats with Henry Paulson about Career, Foreign Policy

Former U.S. Secretary of State Madeleine Albright told an audience at the University of Chicago that her worldview was shaped early in life, when she witnessed the impact the United States had during and immediately following World War II.

Albright explained how terrible things happened to her native Czechoslovakia, when Britain and France signed the Munich Agreement in 1938, allowing Nazi Germany to annex parts of Czechoslovakia without its consent. Only when the United States entered World War II did Czechoslovakia’s plight improve. However, after the war, when the United States and its allies allowed the Soviet Union to liberate Central and Eastern Europe, it led to 50 years of communism. (more…)

Wildlife Monitoring Cameras Click Jaguar and Ocelot Photos

Automated trail cameras set up by a UA research team have snapped pictures of a male jaguar and a male ocelot roaming the rugged Southern Arizona landscape.

An adult male jaguar and an adult male ocelot have been photographed in two separate Southern Arizona mountain ranges by automated wildlife monitoring cameras. The images were collected as part of the Jaguar Survey and Monitoring Project led by the University of Arizona. Both animals appear to be in good health.

In late November, the UA project team downloaded photos from wildlife cameras set up as part of the research project and found new pictures of a jaguar in the Santa Rita Mountains. A total of 10 jaguar photos were taken by three UA cameras and one Arizona Game and Fish Department camera. The cat’s unique spot pattern matched that of a male jaguar photographed by a hunter in the Whetstone Mountains in the fall of 2011, providing clear evidence that the big cats travel between Southern Arizona’s “sky island” mountain ranges.

Collaring Tapirs – Elephant look-alikes – to Help Them Survive

EAST LANSING, Mich. — A team of Michigan State University researchers will soon be heading into the rainforests of Nicaragua to help an endangered species known as a Baird’s tapir co-exist with local farmers whose crops are being threatened by the animals.

The animals were thought to be extinct in that part of the world until just two years ago when the MSU team discovered them still living there through the use of “camera trapping” – the setting up of still and video cameras in order to “capture” the animal. (more…)

Analysis of Bacterial Genes May Help ID Cause of Dog Brain Disease, Say UF Researchers

GAINESVILLE, Fla. — By analyzing the genes of bacteria, University of Florida researchers have moved a step closer to pinpointing how two brain disorders common in small-breed dogs occur.

The researchers found that the bacteria, known as Mycoplasma canis, invade dog’s cells and suppress their immune system responses. (more…)
