How our unseasonably warm fall is affecting migratory birds (Interlochen Public Radio): 2016 has been on a record-breaking warm streak, according to the National Oceanic and Atmospheric Administration. So what does this unseasonably warm fall mean for birds that need to start packing up and heading south? Andrew Farnsworth, research associate with the Cornell Lab of Ornithology, says how weather patterns affect birds varies by species. Some birds are dramatically affected. Some species may stay around for quite a lot longer than they might otherwise if temperatures are warmer. This effects waterfall: common loon and ducks on the Great Lakes, for example. On the other hand, some species are less affected by temperature, and instead time their trips south based on changes in the amount of daylight, such as warblers known as calendar migrants. Farnsworth says that while in general, birds are able to respond quickly to changes, they might not be able to keep up with the pace of human-caused climate change.
New research shows invasive plants can feed farms, power homes (Interlochen Public Radio): Researchers who work in wetlands in Michigan are taking a new approach to invasive plants. Instead of removing plants like phragmites and switchgrass, they’re harvesting them. They say these plants are a threat to biodiversity, but they can benefit farmers and even power homes. Scientists are working in the middle of the Shiawassee National Wildlife Refuge, which has 10,000 acres of marshes and bogs, forest and farmland. Their team is removing invasive cattails from the area. Once these nutrients have been harvested, they are then put to good use. Working with local farmers, the harvested cattails are shredded and applied directly to crop fields where the biomass breaks down, providing organic material, as well as recycled chemical fertilizer. The invasive plants may have other economic uses as well.
Interactive map helps bridge science-citizen divide (Great Lakes Echo): People can help keep their local lakes, rivers and streams healthier with a new app. The non-profit Ontario Water Rangers won the event put on by the Great Lakes Observing System to encourage the use of open source data either from GLOS or other water data collection services. The app functions like a Google Map. Clicking on a dot zooms in to display small magnifying glasses. Users can then contribute observations including but not limited to wind speed, algae growth or invasive species and read a summary of past observations.
Lake Superior gates to be automated, improving fish spawning (Newstimes): A set of gates that helps control water flow out of Lake Superior is being automated. An 80-acre area of rapids just downstream is one of the Great Lakes’ most productive fish spawning areas. Officials say the project will give the Corps more flexibility to operate the gates in ways that will improve conditions for fish.
