Wildlife corridors could offer new hope for orangutans

Researchers from Cardiff University, University of Adelaide, NGO HUTAN, and Sabah Wildlife Department have been looking at ways to improve wildlife corridors in Borneo as a new method of protecting the endangered orangutan.

According to the researchers, more than 80 per cent of the primate’s habitat has been destroyed in the past 20 years due to demand for agricultural land, leaving the remaining forest fragmented, isolating orangutans from one another and resulting in a major threat to their survival.

The study highlights that establishing wildlife corridors that connect fragmented protected areas will allow animals to move freely from one territory to another. This will be beneficial to gene diversity, as it will minimise the negative impact of inbreeding caused by animals being forced to live in small, isolated territories.

Dr Benoît Goossens from Cardiff University’s School of Biosciences stresses that the study should not be limited to orangutans, but can apply to other wildlife species affected by climate change and decreasing, fragmented territories. “In this study we used the orang-utan as a model, but the knowledge gleaned will be useful for other mammal species,” he explains. “The next phase of our research will focus on corridor establishment and enhancement by recovering riparian reserves from oil palm plantations, to inform land managers about best corridor scenarios.”

The research team included Dr Benoît Goossens from Cardiff University, Stephen Gregory, Damien Fordham and Barry Brook from Australia, and Marc Ancrenaz, Raymond Alfred, and Laurentius Ambu from Sabah Wildlife Department.

Chimpanzees prefer African, Indian music to other music


This music video is called African Traditional Music.

From Wildlife Extra:

Chimps shun music of West and Japan in favour of African, Indian… or peace and quiet

Chimpanzees prefer silence to listening to Western-style music, but they do like a bit of African or Indian rhythm, according to new research published by the American Psychological Association.

Not that the researchers want to be divisive.

“Our objective was not to find a preference for different cultures’ music,” said study co-author Frans de Waal of Emory University. “We used cultural music from Africa, India and Japan to pinpoint specific acoustic properties.

“Past research has focused only on Western music and has not addressed the very different acoustic features of non-Western music.

“While non-human primates have previously indicated a preference of music choices, they have consistently chosen silence over the types of music previously tested.”

Previous research has also found that some non-human primates prefer slower tempos, but the current findings may be the first to show that they display a preference for particular rhythmic patterns, according to the study published in the Journal of Experimental Psychology: Animal Learning and Cognition.

“Although Western music, such as pop, blues and classical, sound different to the casual listener, they all follow the same musical and acoustic patterns. Therefore, by testing only different Western music, previous research has essentially replicated itself,” the authors wrote.

Sixteen adult chimps in two groups participated in the experiment at the Yerkes National Primate Research Center at Emory University.

Over 12 consecutive days for 40 minutes each morning, the groups were given the opportunity to listen to African, Indian or Japanese music playing on a portable stereo near their outdoor enclosure.

Another portable stereo not playing any music was located at a different spot near the enclosure to rule out behaviour that might be associated with an object rather than the music.

The different types of music were at the same volume but played in random order.

Each day, researchers observed the chimps and recorded their location every two minutes with handwritten notes. They also videotaped the activity in the enclosure.

The researchers found that when African and Indian music was played near their large outdoor enclosures, the chimps spent significantly more time in areas where they could best hear the music.

When Japanese music was played, they were more likely to be found in spots where it was more difficult or impossible to hear the music.

The African and Indian music in the experiment had extreme ratios of strong to weak beats, whereas the Japanese music had regular strong beats, which is also typical of Western music.

“Chimpanzees may perceive the strong, predictable rhythmic patterns as threatening, as chimpanzee dominance displays commonly incorporate repeated rhythmic sounds such as stomping, clapping and banging objects,” said de Waal.

“Displaying a preference for music over silence is compelling evidence that our shared evolutionary histories may include favouring sounds outside of both humans’ and chimpanzees’ immediate survival cues,” said lead author Morgan Mingle of Emory and Southwestern University in Austin.

“Our study highlights the importance of sampling across the gamut of human music to potentially identify features that could have a shared evolutionary root.”

Film showing chimps rescued from laboratories receives peoples award

The film Chimps: A New Life, Retirement, which was made by The Humane Society of the United States and features more than 100 government-owned chimpanzees starting a new life at Chimp Haven sanctuary after being rescued from research laboratories, has been named by the Telly Awards a People’s Silver Winner

Attracting more than 11,00 entries a year, the Telly Awards honours the very best local, regional, and cable television commercials and programs, as well as the finest video and film productions, and work created for the Web.

For its 35th season, The Telly Awards joined forces with YouTube to give the public the power to rate videos submitted. In addition to recognition from The Silver Telly Council, The Telly Awards’ judging panel made up of more than 500 accomplished industry professionals, the Internet community helped to decide the winners.

The Silver Telly Council evaluated entries to recognize distinction in creative work. Less than 10 percent of entries are chosen as winners of the Silver Telly, the highest honour.

The emotional film includes scenes that show the chimpanzees stepping out onto grass for the first time, and their faces are in awe to see the sky above them rather than bars of a cage.

Kathleen Conlee, vice president of Animal Research Issues for The Humane Society of the United States said:

“The faces of the chimpanzees from our undercover work is what has fuelled our efforts, and to see them finally reach sanctuary and step out on that grass led to a flood of emotions. But we still have more to do. We are so thankful this award gives us another opportunity to tell their stories as we work to get those chimpanzees remaining in laboratories to the sanctuary they so deserve.”

Rwanda’s mountain gorillas, new film


Wildlife Extra writes about this video:

Rwanda’s mountain gorillas star in new documentary – watch it here

April 2014: Mountain gorillas at the Volcanoes National Park are the subject of a new 15 minute documentary entitled Hope which you can watch [above here]. The short film revisits the mountain gorillas at the park, nearly 47 years after Dian Fossey began her work in the region, and explores the extreme, intensive and sometimes dangerous methods employed to protect the great apes.

The film, narrated by Sir David Attenborough, takes a historical look back to 1967 when Dian Fossey began her work. Fewer than 300 mountain gorillas remained at the time, their population ravaged by poachers, who for years targeted the gorillas to make money, selling infant gorillas to zoos or the hands and heads of the adults as trophies to wealthy tourists.

Dian Fossey was murdered in 1985, her original research centre destroyed, rebuilt and then destroyed again during the civil war in Rwanda in the 1990s. However, despite adversity, the work never stopped. Today the Karisoke Research Center has a new home where 120 people continue Dian’s work, as the Dian Fossey Gorilla Fund International.

The charity employs teams of trackers who follow the gorillas every day. They monitor each gorilla, ensuring its safety and health, risking their lives in a region that is still plagued by violence.

“The number of mountain gorillas had become so depleted in Rwanda by the late 1960s that extreme measures were needed to protect the remaining population and allow it to increase,” said David Attenborough. “The work at the Volcanoes National Park by the Dian Fossey Gorilla Fund International absolutely must continue, if we are to protect this species of great ape, which is still critically endangered. The film Hope will once again bring to light the fragile existence of the mountain gorillas and the work that goes into protecting them. By watching and sharing this very important film you will be helping the people saving the gorillas.”

On Rusinga Island in Kenya‘s Lake Victoria, paleontologist Will Harcourt-Smith is leading an effort to recreate the environments inhabited by primitive primates—apes of the genus Proconsul. Studying the adaptive changes of our ancient ancestors helps scientists trace the origins of adaptability in modern humans.

Fossil Forest Discovery Sheds Light on Environment Inhabited by Early Apes

A fossil forest discovery by researchers from Baylor University and an international team of scientists has shed light on the environment inhabited by early apes on Rusinga Island, Kenya. Researchers found fossils of tree stumps, calcified roots and fossil leaves. Researchers say the fossil find indicates that Proconsul and its primate relative, Dendropithecus, lived in a dense, closed canopy tropical seasonal forest about 18 to 20 million years ago. The research was published here in Nature Communications.

Daniel Peppe, Ph.D., assistant professor of geology in Baylor’s College of Arts and Sciences and co-author of the study, says in a Baylor release, “Our research findings provide direct evidence and confirm where the early ape lived about 18 to 20 million years ago. We now know that Proconsul lived in a closed-canopy, tropical seasonal forest set in a warm and relatively wet local climate.”

Fossils of a single Proconsul were also found among the geological fossil forest deposits.

Lauren Michel, lead author of the study and a doctoral student in the geology department at Baylor, says, “The varying diameters of the tree stumps coupled with their density within the fossil soil, implies that the forest would have been comprised of trees with interlocking or overlapping branches, thus creating a canopy.”
