Animal rights advocates launch new petition to drive halt to wolf hunting (Detroit Free Press): Animal rights advocates launched a petition drive on Monday to repeal the law that would give control over setting wolf hunts to the Natural Resources Commission. Passed in May, the law bypassed a petition drive mounted by activists last year that would have put a halt to a hunt of grey wolves in the Upper Peninsula. If the petition drive is successful, voters will face two ballot issues on wolves in November.

Michigan’s recycling rate is lowest in Great Lakes region (WKAR):Michigan’s recycling rate is just 20 percent, 10 percent lower than the regional average. Governor Rick Snyder is hoping to change that. In 2012, he identified increasing recycling rates as a priority for his administration.

How ‘insect soup’ DNA could help conservation efforts (Mother Nature Network): Researchers are turning to a method known as “metabarcoding” for identifying endangered insect species across the globe. The process involves identifying species from fragments of DNA in a single bulk sample, such as an “insect soup” or various crushed bugs. Though it may seem strange, researchers believe metabarcoding could allow could enable scientists to identify endangered insects that would otherwise go unnoticed across various regions and continents.

Vigilant residents take on lake invaders with hot water (Great Lakes Echo): The Glen Lake Association is doing its part to fight against invasive species with its boat-wash program in the northwestern Lower Peninsula. The boat wash station uses a warm-water spray to clean the hull and flush the engine of boats that have been in another lake. The program began in 1994 and efforts seem to be paying off; Big and Little Glen lakes are nearly invasives-free.

Climate change alters apples’ flavor (Conservation Magazine): A new study reports that Fuji apples are becoming softer and sweeter as a result of global warming. Scientists studied the apples from 1970 to 2010 and found that the annual average air temperature at the site increased by 0.31 to 0.34 degrees Celsius. Over that same time period, the apples’ acid level and firmness dropped.
