“It isn’t just the climate impacting the vegetation but the vegetation impacting the climate,” Bjartmar Sveinbjornsson explained. “As the globe warms up are the forests going to spread and are they going to to amplify the problem or counteract the problem? Are they going to lead to cooling or are they going to lead to warming? We don’t know and we need to know.” Sveinbjornsson said “We need a mechanistic understanding of what is controlling the activities in these ecosystems.”
Bjartmar Sveinbjornsson is a professor of biological sciences and the director of the Environment and Natural Resources Institute at the University of Alaska Anchorage. He’s joined by students in the National Science Foundation’s program Research Experience for Undergraduates; featured in videos are REU participants Amanda Bonavia and Benjamin Russell, students from Rockford University, Chicago, Illinois. Sveinbjornsson, Bonavia and Russell are researching the growth of white spruce trees in the Chugach Mountains of South Central Alaska. They look to define the specifics of how Chugach Mountains trees are growing above the treeline: “Why so small?” video. Russell describes his work checking the age and effectiveness of tree needles in ‘How Tree Needles Help Photosynthesis’ video. And Bonavia images and compares tiny structures inside tree needles in ‘What Is Stomata?’ video.
