As the threat of global warming grows—and with it, the specter of more extreme conditions such as wildfires, droughts and tropical storms—cities across the U.S. are developing policies to reduce their emissions of greenhouse gases, chiefly carbon dioxide (CO2). Even though many local governments are committed to these goals, however, the emissions data they have to… Read more
Evolutionary biologists have long puzzled over how new traits emerge in nature, largely because much of the evolutionary information available is from the distant past. To learn more about how genes influence evolution, these researchers study organism phenotypes—the observable characteristics of an organism that are influenced by genetics and environment—and… Read more
As collaborators on one of the first coordinated ecology research projects to study what happens to streams as they dry across the United States, Northern Arizona University researchers Ben Ruddell and Abe Springer will develop an improved smartphone application for mapping wet and dry reaches of streams.
Based on lessons learned from phone apps developed to map the desert springs of… Read more
The boreal forest, or taiga, is the largest terrestrial biome on Earth, extending across North America, Europe and Asia north of the 50th parallel. Representing nearly one-third of the world’s forest cover, the boreal forest plays a significant role in the planet’s biodiversity. Its coniferous spruce, pine and larch trees flourish in the long, severe winters and short summers of the subarctic climate. The forest… Read more
