Bear baiting may put hunting dogs at risk from wolves

2013-04-18
(Press-News.org) Bear hunters will tell you that a good way to attract a bear is to put out bait. And in 10 states, including Michigan and Wisconsin, that's perfectly legal. Hunting dogs are another useful technique in the bear-hunter's toolkit, and 17 states say that's just fine.

But who else likes bear bait? Gray wolves, that's who. And wolves that are feeling territorial about a bear bait stash can—and sometimes do—kill hunting dogs released at the bait site.

Like most interactions between wildlife and human beings, wolf attacks on hunting dogs illustrate a tangled trade-off: attracting bears for the hunters, attracting danger for their dogs.

Seeking possible ways to reduce potentially lethal encounters between wolves and bear hunting dogs, researchers at Michigan Technological University and the Michigan Department of Natural Resources compared bear hunting practices and regulations in Michigan and Wisconsin.

Joseph K. Bump, a Michigan Tech wildlife ecologist; Dean Beyer Jr. and Brian J. Roell from the Michigan DNR, and students Chelsea Murawski and Linda Kartano report their findings in the April 17, 2013 issue of the Public Library of Science (PLOS) journal PLOS ONE.

The researchers analyzed and compared a variety of factors in Michigan and Wisconsin, from regulations on bear baiting and compensation for hunting dog attacks to statistics such as the ratio of hunters to wolves and percentage of hunters using dogs to hunt bear.

They found that the neighboring states, with similar wolf and bear populations and similar numbers of bear-hunting permits issued per wolf, report dramatically different numbers of wolf attacks on hunting dogs. Wisconsin's relative risk of attack is two to seven times higher than Michigan's.

Bear baiting begins earlier in Wisconsin and lasts longer, the scientists note. "The longer you bait, the more opportunity you provide for wolves to discover and potentially defend bear-bait sites," says Bump. "Most hunters release their dogs at bait sites, and the longer the bait has been around, the more likely hunting dogs are to encounter territorial wolves who have found and are possibly defending the bait. So it appears that baiting is an important factor."

Wisconsin also compensates dog owners $2,500 per hunting dog killed by wolves. In fact, the Wisconsin DNR data show that compensation for wolf attacks on hounds costs the state more than it has spent for wolf attacks on any other category of domesticated animal, including calves, missing calves or cattle.

Michigan does not compensate dog owners for wolf attacks.

"Compensation can have multiple effects," Bump points out. " It is a reporting incentive, but it also creates an incentive for abuse. The net effect of compensation is far from clear, and it is an important factor to study further."

What can be done about wolves that prey on hunting dogs? One quick and obvious response appears to be to reduce the wolf population. In fact, the Wisconsin DNR has announced its intention to reduce the statewide population of wolves by half, from approximately 700 to approximately 350.

Bump and his co-authors recommend more conservation-friendly alternatives such as adjusting baiting regulations to start baiting later and allow it for a shorter time. "If a reduction in depredations is the goal, actions aside from (or in addition to) reducing wolf abundance might achieve that goal," they wrote in the PLOS ONE article.

"If stakeholders are serious about minimizing wolf depredations on bear-hunting dogs, then careful examination of the potentially exacerbating effects of bear baiting would appear to be a good idea," the wildlife ecologist suggests.

Discovery may help prevent HIV 'reservoirs' from forming

2013-04-18
April 17, 2013 — (BRONX, NY) — Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered how the protein that blocks HIV-1 from multiplying in white blood cells is regulated. HIV-1 is the virus that causes AIDS, and the discovery could lead to novel approaches for addressing HIV-1 "in hiding" – namely eliminating reservoirs of HIV-1 that persist in patients undergoing antiretroviral therapy. The study was published today in the online edition of the journal Cell Host & Microbe. Antiretroviral therapy can reduce blood levels of HIV-1 until ...

Blood pressure out of control at safety-net clinics

2013-04-18
Federally funded safety-net clinics for the uninsured lag behind other health care providers in controlling blood pressure among the low-income patients who rely on them for care, a new Michigan State University analysis suggests. High blood pressure, or hypertension, is a major risk factor for cardiovascular complications including heart disease and stroke, and is especially common and dangerous for patients with diabetes, said lead researcher Adesuwa Olomu, associate professor in the MSU Department of Medicine. In recent decades, a growing share of the 67 million ...

Anti-sickling therapies should be focus for sickle cell science

2013-04-18
AUGUSTA, Ga. – Pain is an undeniable focal point for patients with sickle cell disease but it's not the best focus for drug development, says one of the dying breed of physicians specializing in the condition. Rather scientists need to get back to the crux of the disease affecting 1 in 500 black Americans and find better ways to prevent the hallmark sickling that impedes red blood cells' oxygen delivery, damaging blood vessel walls and organs along the way, said Dr. Abdullah Kutlar, Director of the Sickle Cell Center at the Medical College of Georgia at Georgia Regents ...

Astronomers discover massive star factory in early universe

2013-04-18
Smaller begets bigger. Such is often the case for galaxies, at least: the first galaxies were small, then eventually merged together to form the behemoths we see in the present universe. Those smaller galaxies produced stars at a modest rate; only later—when the universe was a couple of billion years old—did the vast majority of larger galaxies begin to form and accumulate enough gas and dust to become prolific star factories. Indeed, astronomers have observed that these star factories—called starburst galaxies—became prevalent a couple of billion years after the Big ...

The doctor won't see you now? Study: US facing a neurologist shortage

2013-04-18
MINNEAPOLIS – Americans with brain diseases such as Alzheimer's disease, Parkinson's disease or multiple sclerosis (MS) who need to see a neurologist may face longer wait times or have more difficulty finding a neurologist, according to a new study published in the April 17, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology. The findings are being released as nearly 150 neurologists will descend on Capitol Hill next Tuesday, April 23, 2013, to encourage Congress to protect patients' access to neurologists and ensure there will be ...

Teens' brains are more sensitive to rewarding feedback from peers

2013-04-18
Teenagers are risk-takers — they're more likely than children or adults to experiment with illicit substances, have unprotected sex, and drive recklessly. But research shows that teenagers have the knowledge and ability to make competent decisions about risk, just like adults. So what explains their risky behavior? In a new report, psychological scientists Laurence Steinberg and Jason Chein of Temple University and Dustin Albert of Duke University argue that some teens' risky behavior reflects the unique effect of peer influence on the still-developing teenage brain. Their ...

Hop, skip or jump? Study says no to all of the above

2013-04-18
CAMBRIDGE, MA -- Osteoarthritis, which affects at least 20 percent of adults in the United States, leads to deterioration of cartilage, the rubbery tissue that prevents bones from rubbing together. By studying the molecular properties of cartilage, MIT engineers have now discovered how the earliest stages of arthritis make the tissue more susceptible to damage from physical activities such as running or jumping. The findings could help researchers develop tests to diagnose arthritis earlier in patients at high risk for the disease and also guide engineers in designing ...

X-ray view of a thousand-year-old cosmic tapestry

2013-04-18
This year, astronomers around the world have been celebrating the 50th anniversary of X-ray astronomy. Few objects better illustrate the progress of the field in the past half-century than the supernova remnant known as SN 1006. When the object we now call SN 1006 first appeared on May 1, 1006 A.D., it was far brighter than Venus and visible during the daytime for weeks. Astronomers in China, Japan, Europe, and the Arab world all documented this spectacular sight. With the advent of the Space Age in the 1960s, scientists were able to launch instruments and detectors ...
