Ponderosa Pine Biomass Relationships Vary With Site Treatment And Site Productivity, Joy Drohan

Joint Fire Science Program Briefs (2007-2012)

Allometric equations, which express biomass as a function of tree size, are often used to estimate the amount of fuel in a site’s canopy. Most managers assume that one allometric equation per species is suffi cient, or that any error introduced by extrapolation is irrelevant. This work showed, however, that the allometric biomass relationship for ponderosa pine likely changes over space and time. The researchers concluded that for maximum accuracy, allometric equations for ponderosa pine should account for stand management history and site productivity. Thinned trees replaced their foliage within about 4 years, and 8–10 years post-thinning, growth had stabilized. …

Modifying The Model To Mitigate Crown Fire: Improving Estimates Of Canopy Fuels For The Black Hills (And Beyond), Christina Frame

Joint Fire Science Program Briefs (2007-2012)

Managers of most coniferous forests in the western United States aim to create and maintain forest structures that are less susceptible to the initiation and spread of crown fire. To achieve this end, they use models that predict potential fire behavior, and these models rely on accurate estimates of canopy structure, including canopy base height (CBH) and canopy bulk density (CBD). Managers predict CBD through use of the Fire and Fuels Extension to the Forest Vegetation Simulator (FFE-FVS). However, the equations used by FFE-FVS to predict crown mass are based on estimates solely from northern Montana and Idaho, and therefore …

Woodpecker Habitat After The Fire, Jake Delwiche

Joint Fire Science Program Briefs (2007-2012)

Public land managers are asked to minimize fuel levels after fires, including using techniques such as salvage logging. They are also responsible for maintaining suitable wildlife habitat, especially for species of concern to state and federal agencies. An area where these responsibilities could conflict is in the use of salvage logging in burned-over areas that also represent good habitat for certain wildlife such as woodpeckers. Controversy over this conflict has led to litigation. Public land management agencies need consistent design criteria to maintain suitable habitats for these birds. Little information has existed on how to assess potential effects of postfire …

Post-Fi Re Logging: An Effective Tool For Managing Future Fuels In Coniferous Inland Northwest Forests, Joy Drohan

Joint Fire Science Program Briefs (2007-2012)

This study involved a chronosequence of 68 stand-replacing wildfires that happened between 1970 and 2007 in dry coniferous forests of eastern Washington and Oregon. The authors compared snag decay and surface fuel accumulation with and without post-fire logging. Without logging after a fire, woody fuels accumulate for 15–30 years because the rate of fuel deposition on the ground is greater than the rate of wood decay. Stands that were more dense prefire have greater accumulations of fuel. Predominant tree species and size influenced rates of fuel deposition and snag decay. Thin trees fell before larger trees and ponderosa pines typically …

Fire Helps The Lonesome Pine, Jake Delwiche

Joint Fire Science Program Briefs (2007-2012)

Regeneration of Table Mountain pines in the Southern Appalachian has been on the decline since the 1950s. From central Pennsylvania to northeast Georgia, stands of these pines are beginning to be dominated by oaks, particularly chestnut oak, and by hickories. It has been believed that this is because the shade-intolerant pines are being replaced by more shade tolerant hardwoods and shrubs, largely a result of fire exclusion in these areas. Few studies have evaluated fire as a tool for replacement of this species. Some prescriptions have called for intense crown fi res, but these narrow the burning window and cause …

Evaluating The Effects And Effectiveness Of Post-Fire Seeding Treatments In Western Forests, Shari Anstedt

Joint Fire Science Program Briefs (2007-2012)

High-severity wildfires can profoundly affect soils and plant communities, thus requiring emergency rehabilitation treatments such as post-fire seeding. Intended to stabilize soils, reduce erosion, and combat non-native species invasions, post-fire seeding is typically one of the first treatments used by most U.S. natural resource agencies. But despite its widespread use, there is still doubt about the treatment’s actual effectiveness and ecological impacts. Therefore, researchers conducted a study to gain more definitive insight on the ecological effects and usefulness of post-fire seeding. The first part of the study involved an evidence-based review of scientifi c articles, theses, and government publications to …

Optimizing The Location Of Fuel Treatments Over Time At Landscape Scales, Shari Anstedt

Joint Fire Science Program Briefs (2007-2012)

Fuel treatments are a vital part of forest management—but when faced with limited budgets, narrow burning windows, and air quality restrictions, it can be challenging to prioritize where, when, and how fuel treatments should be applied across the landscape to achieve the most benefit. To help ease this process, land managers can turn to various standalone models, capabilities, and decision support systems. While these tools address various aspects of fuel treatments, there is no one integrated solution that can provide the combined functionality needed to handle the strategic scheduling of fuel treatments, the spatial and temporal changes of fuel treatment …

Molecular Analyses Of Changes Induced In The Microbial Populations Of Murine Colon After As(Iii) Exposure, Rishu Dheer

Electronic Theses and Dissertations

The gut microbiota is essential for mammalian health and metabolism. Thus identifying factors that influence the host microbiota is key to understanding the dynamic interplay between the host and its microbiota. Recent studies have shown the effect of chronic exposures of trivalent arsenic [As(III)] in environmentally relevant concentrations on host physiology, however, little is known of how it impacts the gut microbiota.

This study examined the hypothesis that environmentally relevant concentrations of As(III) in drinking water will directly affect the murine colon microbial composition and physiology. The colon microbial communities from 10 and 250 ppb of As(III) exposed mice were …

Expression Of The Distalless-B Gene In Ciona Is Regulated By A Pan-Ectodermal Enhancer Module, Steven Q. Irvine, David A. Vierra, Brad J. Millette, Matthew D. Blanchette, Rachel E. Holbert

Biological Sciences Faculty Publications

The Ci-Dll-B gene is an early regulator of ectodermal development in the ascidian Ciona intestinalis (Imai et al., 2006). Ci-Dll-B is located in a convergently transcribed bigene cluster with a tandem duplicate, Ci-Dll-A. This clustered genomic arrangement is the same as those of the homologous vertebrate Dlx genes, which are also arranged in convergently transcribed bigene clusters. Sequence analysis of the C. intestinalis Dll-A-B cluster reveals a 378 bp region upstream of Ci-Dll-B, termed B1, which is highly conserved with the corresponding region from the congener Ciona savignyi. The B1 element is necessary and sufficient to …

Geological Sciences Faculty Publications

Processes controlling the composition of seafloor hydrothermal fluids in silicic back-arc or near-arc crustal settings remain poorly constrained despite growing evidence for extensive magmatic–hydrothermal activity in such environments. We conducted a survey of vent fluid compositions from two contrasting sites in the Manus back-arc basin, Papua New Guinea, to examine the influence of variations in host rock composition and magmatic inputs (both a function of arc proximity) on hydrothermal fluid chemistry. Fluid samples were collected from felsic-hosted hydrothermal vent fields located on Pual Ridge (PACMANUS and Northeast (NE) Pual) near the active New Britain Arc and a basalt-hosted vent field …

Biological Sciences Faculty Publications

This study evaluates the effects of a spearmint (/-carvone) and wintergreen oil (methyl salicylate) emulsion (CMSE) on age 1 landlocked Atlantic salmon Salmo salar sebago (hereafter salmon). Salmon were immersed in either 257 µl/L CMSE or 75 mg/L tricaine methanesulfonate (MS-222) to induce anesthesia (stage 4), useful for emersion and noninvasive husbandry procedures, and then salmon were recovered in fresh water. Induction was quicker in the CMSE group; however, recovery was quicker in the MS-222 group. A second experiment was conducted in which salmon were immersed in 257 µl/L CMSE for 8.5 min, or 75 mg/L MS-222 for 8.5 min …

Review Of The Interactions Between Catfishes And Freshwater Mollusks In North America, Jeremy S. Tiemann, Stephen E. Mcmurray, M. Christopher Barnhart, G. Thomas Watters

College of Natural and Applied Sciences

Catfishes are important in freshwater ecosystems not only as consumers, but also as essential partners in symbiotic relationships with other organisms. Freshwater mollusks are among the many organisms that have interactions with catfishes. For example, ictalurids are hosts for larvae of several native freshwater mussel species. The larvae, which attach briefly to gills or fins of fish to complete their development to the free-living juvenile stage, disperse via upstream and downstream movement of host fish. In turn, freshwater mussels serve as a food source for some catfish species while other catfish species may use spent mussel shells for habitat. Ictalurids …

Department of Surgery Faculty Publications

The history of ascorbic acid (AA) and cancer has been marked with controversy. Clinical studies evaluating AA in cancer outcome continue to the present day. However, the wealth of data suggesting that AA may be highly beneficial in addressing cancer-associated inflammation, particularly progression to systemic inflammatory response syndrome (SIRS) and multi organ failure (MOF), has been largely overlooked. Patients with advanced cancer are generally deficient in AA. Once these patients develop septic symptoms, a further decrease in ascorbic acid levels occurs. Given the known role of ascorbate in: a) maintaining endothelial and suppression of inflammatory markers; b) protection from sepsis …
