Old-growth forests are what giant pandas need

12.01.2011
The results of a study recently published in the journal Biology Letters indicate that giant pandas need old-growth forests as much as bamboo forests.

This work, which was completed through the collaborative efforts of scientists from the Chinese Academy of Science, San Diego Zoo Global, China West Normal University, China Wildlife Conservation Association and the Sichuan Forestry Department, could assist conservationists in creating strategic plans that help conserve this critically endangered bear species.

"In this study we show that pandas are associated with old-growth forests more than with any ecological variable other than bamboo," said, Ron Swaisgood, Ph.D., one of the authors of the work and a panda researcher with the San Diego Zoo. "This finding indicates that in order to conserve this species, we need to conserve both bamboo and old-growth forests."

The study, which was conducted from 1999 through 2003, includes data collected from the panda's range in the Sichuan province of China. A key element to the success of this endeavor was the scale of the study, which contributed important information.

"But maps and measures of habitat suitability are only as good as the underlying biological assumptions, which are sometimes influenced by the scale over which data are obtained, " states the study. "Modellers of panda habitat have not ignored the available ecological databut have been forced to rely on data collected over limited temporal and spatial scales."

Giant pandas are unique among bear species for their reliance on an almost completely herbivorous diet that consists largely of bamboo. This dependence on a bamboo diet has indicated the importance of conserving bamboo forests in order to conserve giant pandas. Information about the panda's additional dependence on old-growth forests is expected to affect conservation efforts for this species in the future.

The 100-acre San Diego Zoo is dedicated to the conservation of endangered species and their habitats. The organization focuses on conservation and research work around the globe, educates millions of individuals a year about wildlife and maintains accredited horticultural, animal, library and photo collections. The Zoo also manages the 1,800-acre San Diego Zoo Safari Park (historically referred to as the Wild Animal Park), which includes a 900-acre native species reserve, and the San Diego Zoo Institute for Conservation Research. The important conservation and science work of these entities is supported in part by The Foundation of the Zoological Society of San Diego.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
