Denitrification may be favored within topographic depressions in otherwise flat fields that are prone to ponding, establishing “hotspots” of N2O emissions. The location of N2O hotspots may also depend on the distribution of soil microbial communities that are responsible for the production and consumption of N2O in soils. Yet, relating soil...AuthorsAlexander H. Krichels, Robert A. Sanford, Joanne C. Chee-Sanford, Lynn Connor, Rachel Van Allen, Angela D. Kent, Wendy H.

- Family forest ownerships are classified in federal income tax law as either personal use, investment, or trade or business, and this classification determines the tax rates, deductions, credits, and filing requirements that apply. Tax classification, therefore, has implications for landowners’ overall profit potential and the economic sustainability of forest management. However, the relative proportion of family forest owners in each tax classification has never been estimated before, though many studies have looked at the typologies of family forest owners based on their forest management be...AuthorsShivan Gc, Gregory E.

- Selected organosilicon compounds proved effective in stabilizing waterlogged wood dimensions upon drying. However, detailed knowledge about their effect on wood is necessary before introducing them as safe waterlogged wood consolidants in conservation practice. Our previous research showed that organosilicons can chemically react with wood polymers, infiltrate cell walls and/or fill cell lumina. These interactions can mechanically reinforce the cell wall or have a plasticizing effect on wood, depending on the compound applied. To better understand their stabilizing effect on waterlogged wood, ...AuthorsNayomi Plaza, Sai Venkatesh Pingali, Magdalena BrodaKeywordsSourceJournalYear2025
- Protected areas play an important role in wildlife conservation, yet evaluating their effectiveness can be difficult. We assessed the efficacy of protected areas for Mexican Spotted Owls (Strix occidentalis lucida) by examining how federally designated Protected Activity Centers (PACs) and nest cores aligned with true Mexican Spotted Owl space use for roosting and foraging. We also examined if Mexican Spotted Owls used multiple PACs - a behavior commonly observed in California Spotted Owls (Strix occidentalis occidentalis) - and how Mexican Spotted Owl home range size compared to PAC size. We ...AuthorsDana S. Reid, Ceeanna J. Zulla, Nicholas F. Kryshak, Jack Williams, Shaula J. Hedwall, Rebecca Kirby, Gavin M. JonesSourceJournal of Raptor Research, 59(1): 1-11.Year2025
- Forest management activities that are intended to improve forest health and reduce the risk of catastrophic fire generate low-value woody biomass, which is often piled and open-burned for disposal. This leads to greenhouse gas emissions, long-lasting burn scars, air pollution, and increased risk of escaped prescribed fire. Converting low-value biomass into biochar can be a promising avenue for advancing forest sustainability and carbon neutrality. Biochar can be produced either in a centralized facility or by using place-based techniques that mitigate greenhouse gas emissions and generate a hi...AuthorsDipita Ghosh, Deborah S.

- Forest soil amendments are increasingly used in western US forests to dispose of unmerchantable woody residues, reduce wildfire risk, and improve soil properties. Our objective was to determine the effect of fertilizer and organic amendments on tree growth and organic matter decomposition after thinning. Treatments were a control, three single soil amendments (wood chips, fertilizer, and biochar), and one combined soil amendment (biochar + fertilizer), each applied after thinning a ponderosa pine (Pinus ponderosa Dougl. ex. Laws) stand. After 10 years, amendment treatments had no effect on tre...AuthorsDeborah S. Page-Dumroese, Martin F. Jurgensen, Chris A. Miller, Joanne M. Tirocke, Derek N. Pierson, Cole Mayn, Mark J.

- Wildfires and other disturbances play a fundamental role in regenerating lodgepole pine forests. Though severe, stand-replacing fires are typical of this ecosystem, they can have dramatic impacts on soil properties and biogeochemical processes that influence the rate and composition of vegetation recovery. Organic soil amendments are often applied to manage post-fire erosion, but they can also improve soil moisture and nutrient retention and potentially alter the trajectory of post-fire revegetation. We compared change in soil nutrients, microbial communities, and understory plant cover and co...AuthorsSophia Kaiser, Timothy S. Fegel, David M. Barnard, Adam L. Mahood, Kya Sparks, Kaela K.

- With increasing frequency and severity, coastal cities are facing the effects of extreme weather events, such as sea-level rise, storm surges, hurricanes, and various types of flooding. Recent urban resilience scholarship suggests that responding to the cascading complexities of climate change requires an understanding of cities as social-ecological-technological systems, or SETS. Advances in data visualization, sensors, and analytics are making it possible for urban planners to gain more comprehensive views of cities. Yet, addressing climate complexity requires more than deploying the la...AuthorsMathieu Feagan, Tischa A. Muñoz-Erickson, Robert Hobbins, Kristin Baja, Mikhail Chester, Elizabeth M.

- Intense precipitation events pose growing threats to forest infrastructure causing flooding, and soil erosion and deposition, creating bottlenecks at road-stream crossing structures (RSCS). We describe a hillslope-scale ensemble hydro-geomorphological vulnerability assessment integrating geospatial Streambank Erosion Vulnerability Assessment (SBEVA), Modified Revised Soil Loss Equation (MRUSLE), and process-based Water Erosion Prediction Project (WEPP) model into an ensemble hydro-geomorphologic vulnerability index (EHVI) for USDA Forest Service (USFS) managed 194 road-culverts at the Hubbard ...AuthorsSourav Mukherjee, Sudhanshu Panda, Devendra M.

- Ecological economics envisions problem-solving collaborative efforts characterized by disciplinary diversity and participants within and outside of research professions. Pursuit of its ambitious vision has led to ambiguity in terms of ecological economics’ paradigms, methodology, and subject matter. There remains a need for comprehensive methodologies and for nuanced discussions of methodological pluralism and action-oriented research practice. We present a pragmatist ecological economics as one foundation to practicing ecological economics. We synthesize the basic normative assumptions of a p...AuthorsChristopher A. Armatas, William T.
