Yellowstone’s long-distance travelers in trouble, study says

20.04.2004


Populations of antelope, elk and deer face growing gauntlet of gas fields and highways



Bottlenecks from increased development are choking off ancient migration routes for wildlife in the Greater Yellowstone Ecosystem (GYE) and other regions, according to a study by the New York-based Wildlife Conservation Society (WCS) that appears in the current issue of the journal Conservation Biology.

Increased gas development in particular is making it more and more difficult for species like pronghorn antelope to migrate in and out of Yellowstone National Park, a round-trip of 340-miles – the longest of any land-based mammal from Argentina to Toronto. Its current winter migration route consist is a perilous network of narrow mountain passes to 100-yard-wide strips along highways. Carbon dating by archeologists shows that some of these routes have been used for 5,800-7,800 years, according the authors.


"From wildebeest in Africa to antelope in Wyoming, long distance migrations are one of the world’s most stunning yet imperiled biological phenomena," said the study’s lead author Dr. Joel Berger, a WCS biologist based at a field office in Moose, Wyoming. "Here in the U.S., pronghorn and other species are in jeopardy of losing what little migratory ability they have left."

According to the authors, approximately 8,500 energy-extraction sites exist on public lands in southwestern Wyoming, just below the Greater Yellowstone Ecosystem, the 40,000 square-mile region surrounding Yellowstone and Grand Teton National Parks. An additional 15,000 more are planned for the next decade, according to Berger. The effects of this spate of drilling activity on antelope, and other migratory species including elk and mule deer, are largely unknown.

"Unlike the plethora of Alaskan studies designed to understand possible petroleum-related disruption to migratory caribou, no scientific literature exists to assess possible energy-related effects on migration in the GYE," Berger said.

To protect these traditional migrations, the authors of the study suggest that a network of strategically planned protected migration corridors should be established.

Im Focus: New Method of Characterizing Graphene

Scientists have developed a new method of characterizing graphene’s properties without applying disruptive electrical contacts, allowing them to investigate both the resistance and quantum capacitance of graphene and other two-dimensional materials. Researchers from the Swiss Nanoscience Institute and the University of Basel’s Department of Physics reported their findings in the journal Physical Review Applied.

Graphene consists of a single layer of carbon atoms. It is transparent, harder than diamond and stronger than steel, yet flexible, and a significantly better...

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
