The Research Roundup: Water Quality, Wildlife, Night Skies, and So Much More

Environments in the dry Southwest will become less suitable for pinyon–juniper woodlands than those in the northern Great Basin and the Colorado Plateau.

Bucking the trend for most cave-dwelling animals, one species of cave spider is widely dispersed across the U.S. Scientists wonder how.

The data showed more buildings and fewer trees in one season than in another—but not because of land use changes.

Scientists tested water samples from 46 national parks in the largest study of its kind.

More than 30 years of information reveal factors that could help predict whether nests will succeed.

National parks serve as refuges for many amphibians, but populations have still declined. The authors propose ways to help them.

The amount of tree cover around a lake may be more responsible for mercury in fish than contaminated rain or snow.

A plan to save “core” sagebrush habitat helped some parks use scarce federal dollars where they’ll have the most impact.

It’s the first detailed application of the Coastal and Marine Ecological Classification Standard (CMECS) in rocky intertidal areas of Maine.

Activity and occurrence metrics are complementary but not interchangeable.
