Preliminary DNA analysis completed on California wolverine

07.04.2008
Preliminary results from DNA analysis of wolverine scat samples collected on the Tahoe National Forest do not match those of historic California wolverine populations, according to U.S. Forest Service scientists.

Geneticists with the agency’s Rocky Mountain Research Station recently began analyzing samples, when wildlife biologists with the Tahoe National Forest and California Department of Fish and Game began sending hair and scat samples they collected from wolverine detection sites on the national forest to a lab in Missoula, Mont.

The interagency effort began in March after an Oregon State University graduate student working on a cooperative project with the U.S. Forest Service’s Pacific Southwest Research Station photographed a wolverine, an animal whose presence has not been confirmed in California since the 1920s.

DNA analysis is critical to scientists working to determine if the animal first photographed on February 28 and in later detection work is a wolverine that dispersed from outside of California, escaped from captivity or is part of a historic remnant population.

Key findings from the preliminary analysis indicate the animal in the photographs is a male wolverine that is not a descendent of the last known Southern Sierra Nevada population, said Bill Zielinski, a Forest Service scientist with the Pacific Southwest Research Station and an expert at detecting wolverine, marten and fisher. It also does not genetically match populations in Washington, he said.

U.S. populations are found largely in the Northern Cascades in Washington, and Northern Rockies in Montana, Wyoming and Idaho. The nearest known resident population is about 600 miles northeast of the Tahoe National Forest in Idaho’s Sawtooth Range.

Scientists determined the sample is a haplotype A, which is a genetic type that is found throughout the Rocky Mountains, Alaska and Canada, according to Michael Schwartz, conservation genetics team leader at the Rocky Mountain Research Station. He said haplotype A is not found in historic California samples or in the Cascade Range.

Additional analysis of the wolverine DNA to pinpoint this animal’s origin will be conducted by the Rocky Mountain Research Station and independent labs, Schwartz said.

“We can exclude the Washington and the Southern Sierra Nevada populations from haplotype A, but more information about the population of origin will be investigated through additional genetic analysis,” Zielinski said.

Genetic samples for historic California wolverine populations were gathered from museum pieces, fur pelts and scientific specimens, he said.

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...
