Invasive emerald ash borer hurts Michigan timber sales (Great Lakes Echo): The emerald ash borer first caused an infestation in Michigan in 2002. The beetle eats the layer below bark, causing a lack of nutrients and ultimately leads to the death of the tree. The Department of Natural Resources said timber sales are being hurt by the spread of the emerald ash borer. Not all timber is meant to be sold right away, but because of this insect, the process has to be sped up. The infestation is causing a decrease in salvage bid sales and there will be a noticeable decrease in timber sales next year, according to the DNR.

Climate change is making Lake Superior a fishing haven, for the moment (PRI): Lake Superior is warming faster than any other lake on the planet. Because of this, there has been a shift in the species that the lake supports. Lake trout are becoming rarer and are being joined by the walleye in Lake Superior. James Kitchell, an emeritus professor at the University of Wisconsin in Madison, said there will be an economic boost in the short run from this change. However, it will cause problems in the long run. As fish population increases, the amount of food per fish decreases, causing overall growth rates to decline. The warmer temperature of the lake also reintroduces the sea lamprey, a major predator of lake trout.

Algae blooms on Lake Erie getting ‘difficult to control’ (CBC): Massive algae blooms on Lake Erie are becoming harder to control, according to a scientist at the International Joint Commission. The algae blooms are being caused by fertilizer runoff from nearby farms. Raj Bejankiwar of the Lake Erie Ecosystem Priority correctly predicted that Lake Erie would see near-record algae levels because more intense storms cause more intense runoff. The algae is also causing a higher level of toxins in drinking water. This is causing both economic and environmental problems, as 20 percent of the world’s freshwater comes from the Great Lakes.

18-foot-long deep-sea creature found off California (LiveScience): Dive instructor Jasmine Santana found an oarfish carcass while swimming in about 20 feet of water. The animal is rare and serpent-like, and is usually found in much deeper waters. With the help of many others, Santana dragged the carcass onto land, where people took pictures and eventually put the oarfish on ice so it could be shown to students the next day.

Forget polar bears: Global warming will hit the tropics first (Mother Nature Network): Researchers at the University of Hawaii are saying the tropics will suffer “unprecedented” climate change effects in the next ten years. This is predicted to come long before the Arctic and polar bears see effects. Camilo Mora, lead study author and a geographer at the University of Hawaii, Manoa said, “The coldest year in the future will be hotter than the hottest year in the past [150 years].” The amber-eyed jaguar is near the top of the list to become extinct due to climate change.

Farm bill, lake sturgeon, and blueberries: this week in environmental news

By Allison Raeck, MNA Intern

Every Friday, MNA shares recent environmental news stories from around the state and country. Here’s some of what happened this week in environmental and nature news:

International Joint Commission issues Great Lakes report card (Great Lakes Echo): According to the International Joint Commission’s latest progress report, Michigan’s Great Lakes are experiencing some new problems, mainly linked to warmer temperatures. According to Lana Pollack, former Michigan Environmental Council president, warm temperatures are taking their toll on lake ecology, dramatically impacting species that were once considered stable in these areas. The commission summarized that, tough protection measures have greatly improved the quality of the Great Lakes in recent decades, the area now requires a new type of conservational attention.

Stabenow calls for passage of Senate farm bill (East Village Magazine): U.S. Senator Debbie Stabenow joined with Michigan agricultural and conservationist leaders Wednesday to call for the passage of her 2013 Farm Bill. The bill is a major reform of past agriculture programs, and yields $24 billion in spending cuts. The reforms increase investments to create more jobs in the agriculture industry while aiming to save taxpayer dollars overall. The Senate Committee passed the bill by a strong bipartisan vote on May 15, and a final Senate vote is expected next week.

Restoring an ancient Great Lakes fish (Michigan Water Stewardship Program): Federal and state officials have joined with the Gun Lake Band of Potawatomi to rebuild the lake sturgeon habitat in the Kalamazoo River. Currently, the lake sturgeon population is declining below sustainable levels in the area, and fewer than 125 exist in the Kalamazoo River today. Conservationists are attempting to raise these numbers by reconstructing areas of cobblestones, rock and sand at the bottom of the river, which the sturgeon use for spawning.

Does Climate Change Impact Tornadoes? The Scientific Jury Is Still Out (TakePart): Though multiple theories exist, some scientists are beginning to suspect that stronger tornadoes, such as the twister that hit Moore, Oklahoma on May 20, may be linked to climate change. Humid air masses coming off the Gulf of Mexico could increase from warmer global temperatures and, as a result, increasingly clash with cold northern air masses to form more tornadoes. Still, while the Intergovernmental Panel on Climate Change acknowledges this hypothesis, the organization does not believe there is enough data to prove it true at this time.

Honeybees, other bees put to the test pollinating Michigan blueberries (mlive): Planting wildflowers near blueberry plants may increase the crop’s yields, according to a recent study conducted at Michigan State University. The wildflowers attract bees and other pollinating insects, which additionally support blueberry plants. These findings will lead to a larger study funded by the U.S. Department of Agriculture, testing ways to make full use of pollination on a broader scale.
