BOONE, N.C. — Found only in Sumatra and peninsular Malaysia, an endangered primate known as the siamang is at risk of extinction because of loss and degradation of habitat from industrial development and agriculture. Siamangs and other gibbons, however, may be able to survive in human-altered landscapes – so it is important that scientists carefully assess the suitability of different habitat types for conservation management.

“The Fulbright award will provide a golden opportunity for me to build relationships and develop on-the-ground knowledge.”

Dr. Susan Lappan

Appalachian State University’s Dr. Susan Lappan is working to save these creatures and their ecosystem. After researching siamangs in southern Sumatra since 2000, she received a Fulbright Scholar Award for the 2017-18 academic year for a research project titled “Conservation of the Malaysian Siamang in a Changing World.”

Her 10-month grant, in collaboration with the School of Biological Sciences at the Universiti Sains Malaysia, will involve the first systematic survey of siamangs across Malaysia in over 30 years.

What the Fulbright Scholar Award allows her to do

Lappan and her research partners will conduct surveys in protected areas and unprotected forest fragments to determine which forests still have viable populations of siamangs, and to develop a more comprehensive estimate of their population in Malaysia. This information will help determine how habitat characteristics affect siamang population densities and to identify the most important sites for conservation.

Lappan also aims to create momentum for a gibbon conservation movement in the area. Working with government agencies, such as the Malaysian Department of Wildlife and National Parks, local universities and non-governmental organizations like the recently formed Malaysian Primatological Society, Lappan hopes to increase local interest in and knowledge about gibbon conservation, and to develop a feasible plan of action to ensure the future of the Malaysian siamang.

The extended stay in Malaysia also will allow her to develop relationships with Malaysian primatologists and conservation professionals, while working with the next generation of Malaysian primatologists and conservationists to maximize the impact of her research within the area.

The siamang’s ecological and cultural importance

Lappan is turning her attention to Malaysia because, she said, “almost no information is available about the current status of siamangs in peninsular Malaysia.” Yet, it’s greatly needed. Peninsular Malaysia contains some of the oldest forested areas in the world, she said, but approximately half of the original forest has been converted to other land uses.

“Research at many sites has shown that siamangs and other gibbons are important components of functioning ecosystems as ecological competitors, plant predators and seed dispersers,” said Lappan. “So the loss of siamangs from any ecosystem that they have inhabited for millennia is likely to lead to a cascade of additional negative impacts. The need for information about Malaysian siamangs is not simply a point of academic curiosity but rather a point of vital conservation interest.”

The species also has cultural importance, Lappan said. “Because of their charisma and beautiful songs, siamangs are featured in Malay folktales and are important to local culture… The haunting beauty of gibbon songs has inspired composers to write music based on their songs and been recognized in the proverb, ‘if you kill a gibbon, you leave seven lonely rivers.’”

Lappan said she feels “incredibly privileged to have had the opportunity to spend time with them in their natural habitat, to hear their songs floating through the early morning air, and to experience the singular thrill that comes from that first glimpse of these incredible acrobats moving through the trees… Gibbons have long, powerful arms and graceful, hook-like hands that make them the world champions at arm-swinging locomotion. Despite being fairly small, 5-11 kg, they can travel through the forest canopy so quickly it almost seems as if they are flying.”

She added, “The Fulbright Scholar Program, by supporting international exchange and cooperation, creates opportunities for scholars from the USA and overseas to develop deeper understanding of other cultures and people, to build relationships, and to initiate productive conversations about difficult problems. I am grateful for the opportunity to work toward these goals in Malaysia and after I return home.”

As a follow-up to the grant, Lappan and colleagues at Universiti Sains Malaysia and the University of Texas-San Antonio are also developing a five-year plan to continue the work they are starting.
