LANSING — When Scott Swinton, an agriculture, food and resource economics professor at Michigan State University, asked landowners if they’d be interested in renting their land for bioenergy crops, the initial response was unexpected.
“The first thing we found was that a number of people that we sent questionnaires to were hoping MSU was secretly trying to find people they could rent land from to grow bioenergy crops,” Swinton said.
“I got scores of phone calls from people telling me they would love to rent their land to MSU if we were interested.”
But that wasn’t what Swinton was looking for. Instead, he was trying to study the willingness of farmers to rent land that isn’t used for crops.Continue reading →
LANSING — As if you needed another reason not to play with stinky piles of algae: Decaying algae can promote the growth of bacteria that could make people and animals sick, according to recent research.
Scientists tracked the changes in bacterial communities while Cladophora algae decays. Bacteria harmful to humans and wildlife were among the many microbes they found, according to their study published in the journal Science of the Total Environment.
It is possible when people come in contact with the algae or water around it, they may be exposed to harmful bacteria, said Murulee Byappanahalli, a microbiologist with the U.S. Geological Survey’s Great Lakes Science Center and one of the authors of the study.
No solid cause-and-effect evidence links human illness to Cladophora, as those types of studies are difficult to conduct, Byappanahalli said.Continue reading →
LANSING — For Michiganders, going “Up North” is a common answer to questions about upcoming vacation plans – and for good reason.
That region holds Michigan’s dunes—landforms integral to the state’s history and tourism. They also hold stories of grassroots advocates and volunteers who successfully preserve these pristine landscapes.
Heather Shumaker, the author of “Saving Arcadia: A Story of Conservation and Community in the Great Lakes” (Wayne State University Press, $22.99), explores the near 40-year battle between Arcadia Dune conservationists and CMS Energy, the holding company of Consumers Energy, a natural gas and electric public utility.
Located along Lake Michigan’s coastline and almost directly across from Wisconsin’s Green Bay, the Arcadia Dunes’ conservation story begins in 1969. Elaine Putney, an orchard farmer, received a knock on her door from a sharply dressed man. The man, Gerald Derks, was offering to buy land from Benzie County residents on behalf of Viking Land Co., which — as it would later turn out — represented Consumers Power Co.Continue reading →
LANSING — Deep below the chill waters of Lake Huron, scientists have found long-submerged physical evidence that prehistoric peoples systematically and strategically hunted caribou thousands of years ago.
Searching 50 miles offshore from Alpena, researchers discovered “drive lanes” — in effect, runways of death that channeled unwitting caribou into the clutches of hidden hunters — and stone hunting blinds where hunters awaited their prey.
“Caribou have a thing for linear features. They like following lines,” said scientific researcher Lisa Sonnenburg of the environmental consulting firm Stantec Consulting Inc. in Hamilton, Ontario. “Line stones up in a row and caribou will follow them. It’s something about how their brains work.”
Today, scientists and shoreline property owners pay close attention to annual fluctuations of Great Lakes water levels, but water levels between 8,350 and 9,000 years ago were unusually low, according to a newly published study by Sonnenburg and John O’Shea, the curator of Great Lakes archaeology at the University of Michigan’s Museum of Anthropological Archaeology.Continue reading →
LANSING — A popular source of nutrition for cattle is a potential site for transferring disease, according to a recent study.
Salt blocks are potential transmitters of tuberculosis from cow to deer and vice versa, said John Kaneene, the lead researcher of a study by Michigan State University’s Diagnostic Center for Population and Animal Health.
The blocks are commonly placed in pastures for cattle to lick. At night, deer can enter the field and lick the same salt.
The study found that if a deer or cow is infected, it can leave that disease on the salt block for the next animal to eat.
“It’s a big finding,” said Kaneene, who is an epidemiology professor at MSU. “We kept on saying, ‘Despite all these efforts, why are we having repeated infections on these cattle farms?’ That’s how we came to salt blocks.”Continue reading →
LANSING — Ballast water entering the Great Lakes from ships may contain viruses dangerous to wildlife and humans, according to a recent study published by the American Chemical Society.
The water used to stabilize vessels may be transporting viruses from ocean water or foreign lakes to the Great Lakes, according to Yiseul Kim, a postdoctoral microbiology researcher at Michigan State University.
Kim’s research involved sampling and detecting virus-like particles using a method that differs from others previously used to study ballast water. The method, called metagenomics, studies chains of viral genetic material sampled directly from the ballast tanks. The researchers then match them to known viral chains.Continue reading →
LANSING — That short burst of tweets you hear from wrens might be the best way to tell if they’re near, but it isn’t the only way.
A good way to predict the bird populations in the Great Lakes is to listen not for the songs of wrens, but for the roar of car engines. A recent study in the Journal of the Society of Wetland Scientists shows where humans are and where wren populations should be – but aren’t.
One of the broadest research projects on two species of wrens in the Great Lakes region found that urban development has a primary influence on where the birds live.
For the most part, where you find people is where you likely won’t find wrens. And the Department of Environmental Quality identifies human development, like agriculture and industry, as key factors in the loss of wetlands, the primary habitat for these birds.
“Human development of the landscape proved to be the best model for predicting where these species can be found,” said Hannah Panci, a member of the Natural Resources Research Institute at the University of Minnesota Duluth and the study’s lead researcher. Continue reading →
LANSING — A 200-pound ship’s radiator interrupted a funeral in 1922 when it plunged from the sky and into the Falk Undertaking Parlors on Military Street in Port Huron.
It came from the Omar D. Conger, a ship blown to pieces when its boiler exploded while docked at Port Huron.
“That part is accurate! It happened! And that’s just bizarre!” said poet Cindy Hunter Morgan, an assistant professor of creative writing at Michigan State University. “When I read that, I thought, I’ve got to build a poem around that.”
LANSING — Predicting water levels in the Great Lakes isn’t as straightforward as it would seem.
A warm winter has led to lower ice coverage — just 5 percent of the Great Lakes was covered with ice as of March 1. The average coverage at this time for the last 40 years has been 43 percent, according to the Great Lakes Environmental Research Laboratory in Ann Arbor.
Less ice means less protection from evaporation and, theoretically, lower water levels, said Jacob Bruxer, a senior water resources engineer with Environment and Climate Change Canada.
But it’s not quite that simple. And not the case now.
That’s because water levels are a function of many factors, Bruxer said.
“Everyone wants to make that into a big story — about how ice cover is affecting water in the lakes,” Bruxer said. “I would just stress that evaporation is very complicated.”Continue reading →
