Air passing upward through the tropical tropopause is “marked” by an annually varying water vapor mixing ratio much as a tape recorder marks a magnetic tape; as the air ascends in the tropical stratosphere, these marks are effaced by a combination of vertical diffusion within the tropics and dilution of...
Despite the critical ecological roles of structural features in forests, ecologically
relevant quantitative measures of structure that allow comparisons among forest stands
are still limited. A new index, the structural complexity index (SCI), was developed to
characterize and compare the structural complexity of different forests. Point patterns
of stem-mapped trees...
Geographic Information Systems (GIS) have become an essential tool for evaluation and monitoring the biophysical data of natural landscapes. This study addresses the potential for using GIS in the social assessment of human landscapes that are associated with geographic regions of interest. Using the communities surrounding Oregon's federally designated Central...
