After more than 15 years of negotiations, the state of Utah and the National Park Service signed a water rights agreement this spring for Arches National Park.

  As cliff swallows return to the Colorado Plateau this spring, they set about building mud nests on cliffs – or, just as often, on manmade structures like bridge abutments or under wide eaves. That takes a lot of work—more than a thousand beakfuls of mud for a new nest.

  Cliff swallows live communally, and they’ll sometimes fast-track the nest-building process by stealing mud from neighbors or laying an egg or two in a nearby nest.

Migratory birds are among the forces that stitch the globe together. Biologists have long known that animals can carry seeds and spores on their bodies, or may eat them and spread them in their waste.

Arid grasslands once covered significant parts of the Southwestern states — as much as 24 million acres in Arizona, for example. American pronghorn were widespread in these open spaces, along with many other grassland-dependent wildlife species. 

When Bea Cooley and Brooks Hart headed down Oak Creek Canyon to do some birding last winter, they had no idea just how close their bird encounters would be.

Soon after the Slide Fire burned 22,000 acres in, and around, Oak Creek Canyon in northern Arizona, researchers from the Forest Service Burned Area Emergency Response - or BAER Program - took stock of its impact on sensitive wildlife species.

In late May of this year, wildfire swept through upper Oak Creek Canyon in northern Arizona. By the time firefighters contained it in early June, the Slide Fire had burned some 22,000 acres of chaparral, mixed conifers, and ponderosa pine forest.

Some 27 national parks and monuments protect the Colorado Plateau’s remarkable canyons, rivers, and wide-open spaces. But, people increasingly visit the plateau to experience another rare natural resource: its dark skies.

In late September, the Intergovernmental Panel on Climate Change released its Summary for Policymakers for part-one of its  massive Fifth Assessment Report. Its message? Earth's climate is warming, and human influence on that warming is clear.

Imagine an adhesive that could take the place of pins and plates when fixing broken bones, or that could replace staples and sutures during surgery. But creating a glue that sticks to a wet surface is no easy task. That's why University of Utah researchers are taking their cues from a proven master of the art - the diminutive caddisfly.
