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.”
In my State of the Campus address, I invited all faculty, staff and students to undertake a grand challenge in which we leverage our unique strengths in Earth and space science and technology.
My vision for the grand challenge is to create a collaborative environment among Earth and space sciences, engineering, business, law, social sciences and humanities faculty members, students and staff as well as public and private sector partners in order to explore, understand and influence how space-based innovations and technologies impact business, law and society. I have named a steering committee to help make this vision a reality, and plan for a Dec. 9 "Imagination Summit."
