Are mountain lions going urban? (Mother Nature Network): Due to excessive hunting and habitat destruction, mountain lions are now making their home in urban areas of the United States, such as Los Angeles and Washington D.C. Researchers say the mountain lions are traveling long distances across the U.S. to find homes. Mountain lions are on the endangered list and were all but extinct in 2011. Since then, they have made a slight comeback.

Michigan lawmakers propose wildlife council to promote hunting, fishing (Great Lakes Echo): Lawmakers want to create a bill that would finance a new wildlife council, headed by the Michigan Wildlife Management Public Education Fund. This council would educate the public on the importance of wildlife management and licensed hunters. The Department of Natural Resources estimates $1.6 million will be collected from hunting and fishing license increases, which will cover the cost to create the council.

Invasive stink bugs swarm across the U.S. (Mother Nature Network): The brown marmorated stink bugs, arriving from Asia, are overshadowing stink bugs native to the U.S. The bug that once bred in only southern Pennsylvania now breeds in 15 states and exists in about 25 more. Chuck Ingels of the Cooperative Extension office in Sacramento calls them the “worst invasive pests we’ve ever had in California.” Besides their stench, the brown marmorated stink bug destroys commercial crops. In 2010 alone, they caused $37 million in damage to Mid-Atlantic apple farms.

Lyons Dam on borrowed time: Endangered species discovery complicates removal project (MLive): The Lyons Dam was set to be removed until biologists from Central Michigan University discovered an endangered species downstream of the dam, the snuffbox mussel. These mussels were added to the endangered species list in 2012 when there was a 62% population decrease. They must be relocated before the dam can be removed. State and federal officials will have to decide where to relocate the mussels, and they would likely not begin this process until next summer.

No cure in sight for loon-killing botulism (Great Lakes Echo): An avian botulism outbreak in northern Michigan has killed more than 1,000 loons. Tom Cooley, a Department of Natural Resources disease lab biologist and pathologist said there is an estimated loon population of 2,000. Conditions in the water make a breeding ground for the bacteria. Scientists believe the loon’s predation on infected fish is causing a rise in deaths. There are no known solutions to stop the botulism from infecting loons.
