Pass the chips and hand over the remote. In a study involving the first-ever daily energy expenditure measurements in apes, a researcher from Washington University in St. Louis and his team have determined that orangutans living in a large indoor/outdoor habitat used less energy, relative to body mass, than nearly any eutherian mammal ever measured, including sedentary humans. All this despite activity levels similar to orangutans in the wild. "It's like finding a sloth in your family tree,"...

Blue whales are able to synchronize the pitch of their calls with an extremely high level of accuracy, and a very slim margin of error from call to call, according to a new study of the blue whale population in the eastern North Pacific. Results were published in the Journal of the Acoustical Society of America. The authors suggest that the uniform pitch used by blue whale populations could allow individual whales to locate potential mates by swimming toward them or away from them. "Blue...

An official said Friday that Indonesia will reserve thousands of hectares of forest in Borneo island for about 200 captive orangutans, which will be released in a conservation drive. "A foundation has asked for a permit on about 86,000 hectares of forests in Kutai area in East Kalimantan (Borneo) to be used for orangutan conservation," forestry ministry secretary general Boen Purnama said. Conservationists have been looking for large areas to try and release the apes as vast tracts of...

Great ape gestures have intentional meaning and are made with the expectation of specific behavioral responses, according to Erica Cartmill and Richard Byrne from the University of St. Andrews in the UK. The study of meaning in animal communication takes a significant step forward with the authors' new systematic approach to assessing intentional meaning in the gestural communication of non-humans, applied here to a group of orangutan gestures. Their work is published in Springer's journal...

Park officials said Thursday that a 30-foot-long dead humpback whale washed ashore near Jones Beach State Park. According to George Gorman, spokesman for the Long Island region of the New York State Office of Parks, Recreation and Historic Recreation, the Riverhead Foundation for Marine Research and Preservation, a nonprofit marine life rescue organization, will make the determination of what to do with the whale's remains. The whale was discovered by parks' staff east of field 6 at Jones...

Research into the long calls of male Orangutans in Borneo has given scientists new insight into how these solitary apes communicate through dense jungle. An acoustic analysis of the calls, published today in Ethology, reveals that the calls not only serve to attract females, but also contain information on the identity and the context of the caller. The international team of researchers, led by Prof. Dr. Carel van Schaik from the University of Zurich, followed three sexually active male...

Conservationists have warned that the world has less than 20 years left to save the orangutan, AFP reported. Experts say the charismatic red ape will become extinct if no action is taken to protect its jungle habitat, as deforestation and the expansion of palm oil plantations have taken a heavy toll in Malaysia and Indonesia, where there are thought to be 50-60,000 orangutans still living in the wild. Tsubouchi Toshinori from the Borneo Conservation Trust said the orangutans' habitat is...

Researchers' theory: An increase in population size may mean sounds used in mate competition need not travel as far as before; acoustic information extracted from songs could be useful population monitoring tool The sound level of songs blue whales sing across the vast expanses of the ocean to attract potential mates has been steadily creeping downward for the past few decades, and a scientist at Scripps Institution of Oceanography at UC San Diego and his colleagues believe the trend may be...

Veterinarians have been tracking three orangutans they implanted with tiny transmitters as part of efforts to protect the endangered primates once they reintroduce them to the wild, a Malaysian official said Monday. French and Austrian veterinarians worked with the Wildlife Department in eastern Sabah state on Borneo island to implant specially designed coin-sized transmitters in the necks of the orangutans for the first time ever in September, said Senthilvel Nathan, the department's chief...

Most of the linguistic functions in humans are controlled by the left cerebral hemisphere. A study of captive chimpanzees at the Yerkes National Primate Research Center (Atlanta, Georgia), reported in the January 2010 issue of Elsevier's Cortex (http://www.elsevier.com/locate/cortex), suggests that this "hemispheric lateralization" for language may have its evolutionary roots in the gestural communication of our common ancestors. A large majority of the chimpanzees in the study showed a...

penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
