Mountain pine beetles are important to the Western United States. They have a very special life cycle that includes staying “supercool,” or dormant, for most of their lives. The scientists in this study wanted to know how this important life cycle could be affected by our changing climate. (This article was published in both the Olympic Winter Games edition of Natural Inquirer and as a standalone monograph.)
