Some populations of mountain pine beetles now produce two generations of tree-killing offspring annually, dramatically increasing the potential for bugs to kill lodgepole and ponderosa pine trees, CU-Boulder researchers have found.
Because of the extra annual generation of beetles, there could be up to 60 times as many beetles attacking trees in any given year, the study found. And in response to warmer temperatures at high elevations, pine beetles also are better able to survive and attack trees that haven't previously developed defenses.
Rounding out a full day of touring CU-Boulder facilities and meeting with faculty, staff and students, NASA Administrator Charles Bolden spoke to a packed house on the afternoon of April 18, 2014.
Bolden acknowledged the close association CU-Boulder has with the space program, calling the university a “pipeline for talent.”
University of Colorado Boulder Libraries is celebrating the launch of the open access repository CU Scholar, housed online at scholar.colorado.edu. This new institutional repository will aggregate and disseminate the wealth of scholarly knowledge created under the auspices of the University of Colorado Boulder and its research units. CU Scholar welcomes materials of scholarly focus, including published journal articles, working papers, technical reports, multimedia content and datasets.
