Vapor intrusion (VI) by volatile organic compounds (VOCs) in the built environment presents a threat to human health. Traditional VI assessments are often time-, cost-, and labor-intensive; whereas traditional subsurface methods sample a relatively small volume in the subsurface and are difficult to collect within and near structures. Trees could...
Alternative pathways to landscape transformation: Invasive grasses, burn severity and fire frequency in arid ecosystems
Robert C. Klinger, Matthew L. Brooks
2017, Journal of Ecology (105) 1521-1533
Arid ecosystems are often vulnerable to transformation to invasive-dominated states following fire, but data on persistence of these states are sparse. The grass/fire cycle is a feedback process between invasive annual grasses and fire frequency that often leads to the formation of alternative vegetation states dominated by...

Kyle E. Anderson, Nancy Glenn, Lucas Spaete, Douglas J. Shinneman, David S. Pilliod, Robert Arkle, Susan McIlroy, DeWayne R. Derryberry
2017, Environmental Monitoring and Assessment (189) 1-12
Terrestrial laser scanning (TLS) provides fast collection of high-definition structural information, making it a valuable field instrument to many monitoring applications. A weakness of TLS collections, especially in vegetation, is the occurrence of unsampled regions in point clouds where the sensor’s line-of-sight is blocked by intervening material. This problem, referred...
