Urban athletes show that for orangutans, it pays to sway

04.07.2012
Swaying trees is the way to go, if you are a primate crossing the jungle. Using human street athletes as stand-ins for orangutans, researchers have measured the energy required to navigate a forest using different strategies and found it pays to stay up in the trees. Their work was presented at the Society for Experimental Biology's meeting in Salzburg, Austria on 2 July 2012.

The findings help us to understand why orangutans spend most of their lives in trees despite being much larger than other tree-dwelling animals. It also helps to explain how these primates get by on their diet of mainly fruit, which does not provide a lot of energy.

Dr Lewis Halsey of the University of Roehampton, who led the study, said: "Energy expenditure could be a key constraint for orangutans – moving through trees could be energetically expensive."

The team found that the most efficient way to cross from one tree to another is usually to sway back and forth on your tree until you can reach the next one. When trees are stiff, it is more efficient to jump.

For heavy primates the tree must be quite stiff before jumping becomes the easier option. According to Halsey: "Heavier orangutans don't jump, and we may have an explanation why."

To compare the energy required to sway trees, climb trees, or jump from branch to branch, Halsey's team created obstacle courses simulating these activities. But instead of orangutans, the participants were parkour athletes, specially trained street gymnasts with good flexibility and spatial awareness. The athletes wore devices that recorded their oxygen consumption as they proceeded through the activities.

Halsey added: "Because primates are not easy to work with, estimates of energy expenditure have been very indirect. We have gone a step closer to understanding these costs by measuring energy expenditure in a model primate – the parkour athlete."

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
