Methodological considerations of terrestrial laser scanning for vegetation monitoring in the sagebrush steppe
Kyle E. Anderson, Nancy Glenn, Lucas Spaete, Douglas J. Shinneman, David S. Pilliod, Robert Arkle, Susan K. 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...

Malcolm S. Itter, Andrew O. Finley, Mevin Hooten, Philip E. Higuera, Jennifer R. Marlon, Ryan Kelly, Jason S. McLachlan
2017, Environmetrics (28) 1-15
Lake sediment charcoal records are used in paleoecological analyses to reconstruct fire history, including the identification of past wildland fires. One challenge of applying sediment charcoal records to infer fire history is the separation of charcoal associated with local fire occurrence and charcoal originating from regional fire activity. Despite a...

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...
Environmental niche models for riverine desert fishes and their similarity according to phylogeny and functionality
James E. Whitney, Joanna B. Whittier, Craig P. Paukert
2017, Ecosphere (8) 1-21
Environmental filtering and competitive exclusion are hypotheses frequently invoked in explaining species' environmental niches (i.e., geographic distributions). A key assumption in both hypotheses is that the functional niche (i.e., species traits) governs the environmental niche, but few studies have rigorously evaluated this assumption. Furthermore, phylogeny could be associated with these...
