One Side Effect Of Hunting Wolves? They're Having More Sex

A new study out of Canada reveals a surprising side-effect that hunting may have on wolves.

Researchers wanted to compare the hormone levels in wolves that often deal with hunters’ fire, versus wolves that are hunted very little. They were able to measure levels of progesterone, testosterone and the stress hormone cortisol by looking at samples of wolf hair from different parts of northern Canada.

Partial Mammoth Skull And Tusk Found In Eastern Idaho

A portion of a mammoth skull and tusk have been uncovered in southeastern Idaho near American Falls Reservoir.

Experts estimate the mammoth lived 70,000 years ago and was about 16 years old when it died.

The bones have been taken to the Idaho Museum of Natural history at Idaho State University in Pocatello where they will eventually be put on display.

The discovery of the bones on Oct. 18 by a volunteer with the U.S. Bureau of Reclamation followed heavy rains in August that caused additional erosion in the area.

Could there be plate tectonics on other worlds? One former Idaho scientist thinks it’s possible. Until now, the movement of pieces of a planet’s crust was found nowhere else in the universe except Earth.

It was the late 1990s and University of Idaho planetary geologist Simon Kattenhorn was looking at one of Jupiter's moons named Europa. NASA’s Galileo orbiter took the pictures of it. Using those images, Kattenhorn discovered something remarkable.

There's A Big Leak In America's Water Tower

The northern arm of the Rocky Mountains is sometimes called "the crown of the continent," and its jewels are glaciers and snowfields that irrigate large parts of North America during spring thaw.

But the region is getting warmer, even faster than the rest of the world. Scientists now say warming is scrambling the complex relationship between water and nature and could threaten some species with extinction as well as bring hardship to ranchers and farmers already suffering from prolonged drought.

Are Western Wildfires Really Getting Worse? 3 Recent Studies Say No

It might seem like fire season is as bad as it’s ever been. But there’s a group of researchers who question that prevailing wisdom.

Three fresh science papers from separate institutions each makes the case that today's forest fires in the West burn less than in historical times. One of the co-authors is Dominick DellaSala, chief scientist at the Geos Institute in Ashland, Oregon.

It Takes 100 Years For Forests To Recover From Wildfire, Study Finds That's Fast

Fire season has come alive in the Northwest. On Monday, 20 homes in Idaho's Sun Valley area were briefly under evacuation when a fire broke out in a nearby canyon. A 5,000-acre fire north of Wenatchee, Washington, continues to threaten houses in the area.

Fires can be devastating to people's lives. But according to new research, at least certain types of forests recovery fairly quickly.

The patchy recovery of lodgepole pine trees after the 1988 Yellowstone National Park fire could be due in part to the effects of squirrels.

Research from the University of Wyoming finds red squirrels could be having an impact on how lodgepole pine forests evolve.

Most of the people who use the Boise Greenbelt have a college degree. And last year, more people used it on weekdays. Those are two big conclusions from two years’ worth of surveys on the 45-year-old trail system.

Jaap Vos is director of the Community and Regional Planning Program at Boise State University. BSU has done surveys on the Greenbelt two years in 2012 and 2013.

Many parts of the U.S. have been getting warmer over the past several decades, and also experiencing persistent drought. Wildlife often can't adjust. Among the species that are struggling is one of the American West's most highly prized fish — the cutthroat trout.

In springtime, you can find young cutthroats in the tiny streams of Montana's Shields Basin. Bend over and look closely and you might see a 2-inch fish wriggling out from under a submerged rock — the spawn of native cutthroats.

Seismologists: Idaho Earthquake Swarm Tapering Off

A swarm of central Idaho earthquakes that rattled Challis residents for more than a month appears to be dying out.

But seismologists say five portable seismographs have provided new information about the area that saw a sequence of quakes up to 4.9 in magnitude, peaking in mid-April.

Mike Stickney with the Montana Bureau of Mines and Geology based in Butte, Montana, says the earthquakes are occurring on a northwest trending zone on the west side of the Salmon River.

Geologists plan to install three portable devices known as seismometers or seismographs in the Challis area in central Idaho to help experts better understand a recent flurry of earthquakes.

The U.S. Geological Survey has recorded a sequence of quakes rumbling the area, the largest of which was a 4.9-magnitude quake on Saturday which shook pictures off walls. Challis residents also felt earthquakes above 4.0-magnitude on Monday and April 10.

University Of Idaho Researchers Find Common Chemical Changes Fetal Monkey Genes

The chemical BPA, or bisphenol A, is commonly found in plastics, soup cans, and store receipts. Scientists continue to study how the chemical affects people. New research from the University of Idaho may sound a cautionary note for humans. 

Gordon Murdoch is an associate professor of physiology at the University of Idaho. He focused on fetal heart development in rhesus monkeys.

For the study, pregnant monkeys were fed fruit containing BPA. “Our question was did it affect the genes in the fetal heart?” he asked, “And to our surprise and dismay, it did.”
