and Overview: The likely direction of change in soil organic carbon (SOC) in the boreal forest biome, which harbors roughly 22% of the global soil carbon pool, is of marked concern because climate warming is projected to be greatest in high latitudes and temperature is the cardinal determinant of soil C mineralization. Moreover, the majority of boreal forest SOC is harbored in surficial organic...

A recent survey of people living in wildland-urban intermix neighborhoods in a portion of the Sierra-Cascade foothills identified perceptions of defensible space that block its rapid and widespread adoption. A companion survey described communication channels used by residents to acquire information about landscaping and identified opinion leadership characteristics. Neither lack of awareness o...

Climate change is expected to alter the geographic distribution of wildfire, a complex abiotic process that responds to a variety of spatial and environmental gradients. How future climate change may alter global wildfire activity, however, is still largely unknown. As a first step to quantifying potential change in global wildfire, we present a multivariate quantification of environmental driv...

Invasive tree removal from grazing lands using costly brush management practices is widely employed. However, wildfire-like natural events can also prevent the increasing trend of woody encroachment in at no cost, instead expensive prescribed burning. This study aims to estimate effects wildfire 2002 on trends during post-wildfire period (2003–20), as well recurrence interval a site United Stat...

OF A DISSERTATION CAN COMMUNITY-BASED NATURAL RESOURCE MANAGEMENT IMPROVE WILDFIRE POLICY PLANNING IN INTERIOR ALASKA? ADDRESSING VALUE DIFFERENCES, INEFFECTIVE PARTICIPATORY PROCESSES, AND CONFLICTS OVER TRADITIONAL ECOLOGICAL KNOWLEDGE

Virtual geographic environments (VGE) are environments pertaining to the relationship between post-humans and 3-D virtual worlds. Post-humans are defined as a combination of humans in the real world with 3-D avatars in 3-D virtual worlds. VGE can be a platform for the public participation in spatial data analyses, in model computation and simulation, and in environmental planning and decision m...

Wildfire is natural in many temperate forests but unnatural tropical rainforests and certain other ecosystems. Human-caused climate change intensifying the heat that drives wildfire. Preventive burning forests, halting deforestation cutting carbon pollution reduce wildfire risks increase forest resilience under change.

Detecting the disappearance of active leks is the most efficient way to determine large declines in greater sage-grouse (Centrocercus urophasianus) populations; thus, understanding factors that influence lek abandonment is critical. We evaluated factors that may have influenced the probability of sage-grouse lek abandonment in the Bighorn Basin (BHB) of north-central Wyoming from 1980 to 2009. ...
