Evaluation Of Smoke Models And Sensitivity Analysis For Determining Their Emission Related Uncertainties, M. Talat Odman Dr., Scott Goddrick Dr., Fernando Garcia-Menendez, Aika Yano Jan 2011

Evaluation Of Smoke Models And Sensitivity Analysis For Determining Their Emission Related Uncertainties, M. Talat Odman Dr., Scott Goddrick Dr., Fernando Garcia-Menendez, Aika Yano

Joint Fire Science Program Research Project Reports

Emissions from wildland (wild and prescribed) fires add to the burden of air pollution and can have adverse impacts on air quality and public health. Numerical models for dispersion and chemical transport, also known as air quality models, can be used to investigate the fire plume evolution and the smoke impacts. However, it is important that the predictive skills of smoke models be evaluated under a wide range of applicable conditions through systematic simulations of past events with existing data. Three models were evaluated in this research: CALPUFF, DAYSMOKE and CMAQ. Different prescribed burn and wildfire episodes occurring throughout the …

Fire And Aquatic Ecosystems In The Context Of Climate Change: A Synthesis For Improved Management, Charles Luce, Penelope Morgan, Kate Dwire, John Buffington, Bruce Rieman, Zack Holden, Matt Dare, Dan Isaak, Claire Mcgrath Jan 2011

Fire And Aquatic Ecosystems In The Context Of Climate Change: A Synthesis For Improved Management, Charles Luce, Penelope Morgan, Kate Dwire, John Buffington, Bruce Rieman, Zack Holden, Matt Dare, Dan Isaak, Claire Mcgrath

Joint Fire Science Program Research Project Reports

Fire will be the proverbial eye-of-the-needle through which many western U.S. mountain, forest, and stream ecosystems will pass as the climate changes. Historic observations show increased dryness and temperatures accompanying more widespread fire and forest die-off. These events may punctuate gradual changes to ecosystems, or may be a mechanism driving stepwise changes in ecosystems. Most western ecosystems are strongly tied to cycles of fire and recovery, and the changing nature of fire will have profound consequences. There is no question that vulnerability assessments of western U.S. ecosystems need to account for fire in their calculus. The biophysical template of the …

Synthesis Of Knowledge Of Extreme Fire Behavior: Volume I For Fire Managers, Paul A. Werth, Brian E. Potter, Craig B. Clements, Mark. A. Finney, Scott L. Goodrick, Martin E. Alexander, Miguel G. Cruz, Jason A. Forthofer, Sara S. Mcallister Jan 2011

Synthesis Of Knowledge Of Extreme Fire Behavior: Volume I For Fire Managers, Paul A. Werth, Brian E. Potter, Craig B. Clements, Mark. A. Finney, Scott L. Goodrick, Martin E. Alexander, Miguel G. Cruz, Jason A. Forthofer, Sara S. Mcallister

Joint Fire Science Program Research Project Reports

The National Wildfire Coordinating Group definition of extreme fire behavior (EFB) indicates a level of fire behavior characteristics that ordinarily precludes methods of direct control action. One or more of the following is usually involved: high rate of spread, prolific crowning/ spotting, presence of fire whirls, and strong convection column. Predictability is difficult because such fires often exercise some degree of influence on their environment and behave erratically, sometimes dangerously. Alternate terms include “blow up” and “fire storm.” Fire managers examining fires over the last 100 years have come to understand many of the factors necessary for EFB development. This …

Fire Ecology And Management Of Non-Forested Ecosystems In Western North America. Final Report: Description Of Organizational Meetings And Development Of A Publication Plan, Matt Brooks

Joint Fire Science Program Research Project Reports

It has been almost 30 years since the last major book on the ecology and management of fire was published that contained extensive information from non-forested ecosystems across western North America (Wright and Bailey 1982). During subsequent years there have been notable books that have focused largely on forested ecosystems (e.g. Agee 1993), and there was one very recent book that addressed many important grassland, shrubland, woodland, and forest areas, but its geographic extent was confined to California (Sugihara et al. 2006). No single book has since matched the geographic scope associated with non-forested ecosystems in western North America as …

Joint Fire Science Program Research Project Reports

Understanding the role of climate variation in governing fire regimes remains one of the central needs in contemporary fire science and management. Ideally, this understanding should encompass both historical and current fire-climatology, and inform both basic science and ecosystem management. In this project, Fire and Climate Synthesis (FACS) we undertook a detailed synthesis of both paleofire and modern fire based on compilations of existing data sets. We also analyzed three major thematic pathways by which climate has impacted fire policy, including direct and indirect climate effects on fire policy. Paleofire. We assembled the largest and most comprehensive data set of …

Fire Regimes Of Montane Grasslands Of The Valles Caldera National Preserve, New Mexico, Donald A. Falk, Craig D. Allen, Robert Parmenter, Thomas Swetnam, Clifford Dils

Joint Fire Science Program Research Project Reports

Montane grasslands are an important ecosystem type in Southwestern landscapes, occurring from the forest borders of piñon-juniper woodland to high elevation subalpine and alpine ecosystems. Thus, they often represent a mosaic element embedded in the forest landscape matrix, playing key roles in processing water and nutrients, and providing habitat for unique suites of species, often at higher levels of diversity than those found in surrounding uplands. Soils, local temperature and moisture gradients, and disturbance all play roles in determining the distribution and extent of montane grasslands. Of these factors, fire plays the most dynamic role in regulating the location and …

Fuel Reduction Treatment Longevity And Crown Response In Interior Ponderosa Pine Forests Of Northern California, Martin W. Ritchie, Carl N. Skinner, Jianwei Zhang Jan 2011

Fuel Reduction Treatment Longevity And Crown Response In Interior Ponderosa Pine Forests Of Northern California, Martin W. Ritchie, Carl N. Skinner, Jianwei Zhang

Joint Fire Science Program Research Project Reports

With increasing interest in fuels treatments to address the high risk of severe fires in the western United States, there is an attendant need to quantify the effectiveness of such treatments. In addition to the immediate effect of reducing levels of combustible material and the attendant impact on fire intensity, resource managers also need to quantify or forecast the longevity of such treatments. Treatments that produce significant, but short-lived reductions in risk of severe wildfire may not be meeting the goals and objectives of managers. This temporal component needs further study and is the subject of this proposal. There are …

Fuel Treatments In Mixed-Pine Forests In The Great Lakes Region: A Comprehensive Guide To Planning And Implementation, Eric Toman, Stanley Gehrt, Charles Goebel, David M. Hix, Roger Williams, Robyn Wilson, Sarah Mccaffrey

Joint Fire Science Program Research Project Reports

Fuel management decisions are made within a larger context of resource management characterized by multiple objectives including ecosystem restoration, wildlife management, commodity production (from timber to less traditional forest products), and provision of recreation opportunities and amenity values. Implementation of fuel treatments is strongly influenced by their perceived influence on and compatibility with overarching management objectives. In some cases these objectives may be complementary while in others they may involve difficult tradeoffs. Such tradeoffs are only further complicated by institutional mandates, limited availability of information, and complex ownership patterns. Like natural resource managers across the U.S., those in the Great …

Relationships Of The Heteronchocleidids (Heteronchocleidus, Eutrianchoratus And Trianchoratus) As Inferred From Ribosomal Dna Nucleotide Sequence Data, W.B. Tan, Mun Yik Fong, L.H.S. Lim

Research Publications (2011 to 2015)

The monogeneans, Heteronchocleidus, Eutrianchoratus and Trianchoratus, were postulated to be closely related based on their haptoral hard parts of three well-developed anchors and one vestigial anchor. In this present study, partial 28S rDNA sequences from 12 heteronchocleidids species (10 Trianchoratus spp. and two Eutrianchoratus spp.) were obtained. Phylogenetic trees generated based on 28S rDNA (from the present study and GenBank) using neighbour-joining (NJ), maximum parsimony (MP), maximum likelihood (ML) and Bayesian inference (BI) analyses show that members of these three genera constitute a clade. Within this main monophyletic clade are the Heteronchocleidus-Eutrianchoratus and the Trianchoratus clades. This suggests that the …
