Climate control of terrestrial carbon exchange across biomes and continents
Yi, Chuixiang; Li, Runze; Wolbeck, John; Xu, Xiyan; Nilsson, Mats B.; Aires, Luis Miguel Igreja; Albertson, John D.; Ammann, ChristophUnderstanding the relationships between climate and carbon exchange by terrestrial ecosystems is critical to predict future levels of atmospheric carbon dioxide because of the potential accelerating effects of positive climate-carbon cycle feedbacks. However, directly observed relationships between climate and terrestrial CO2exchange with the atmosphere across biomes and continents are lacking. Here we present ...
Structural dynamics of tropical moist forest gaps
Hunter, Maria O.; Keller, Michael; Morton, Douglas C.; Cook, Bruce Douglas; Lefsky, Michael Andrew; Ducey, Mark J.; Saleska, Scott ReidGap phase dynamics are the dominant mode of forest turnover in tropical forests. However, gap processes are infrequently studied at the landscape scale. Airborne lidar data offer detailed information on three-dimensional forest structure, providing a means to characterize fine-scale (1 m) processes in tropical forests over large areas. Lidar-based estimates of forest structure (top down) differ from traditional...
