Migration Corridors of Mule Deer in the San Francisco Peaks Herd in Arizona

In 2008, 13 mule deer were GPS collared near the South Rim of the Grand Canyon to understand the impact of Arizona’s State Route 64 on mule deer movement. Unexpectedly, 4 individuals migrated over 50 miles to summer range near the San Francisco Peaks, north of Flagstaff, containing alpine, subalpine, and ponderosa pine habitats. The GPS collars dropped in 2009, but questions

Migration Routes of Mule Deer in the Dubois Herd in Wyoming

Mule deer within the Dubois herd make several long-distance migrations into the heart of the Greater Yellowstone Ecosystem (fig. 26). These migrations originate from winter range in the warm, protected sagebrush valley surrounding Dubois, Wyoming, and extend to the southeast on the Wind River Reservation. Each spring, an estimated 6,000–7,000 deer leave this valley and the

Bottom sediment chemical data at rivermouths and harbors along western Lake Michigan, USA, 2016

Streambed sediment samples were collected in October 2016 from streams tributary to Wisconsin’s western Lake Michigan shoreline. Streams included two Areas of Concern (AOCs), two non-AOC comparisons, and two additional non-AOC study areas.
