- The genus Armillaria is a broad group of basidiomycete (Agaricales, Physalacriaceae) plant pathogens that can have detrimental effects on woody hosts in forested, urban, and horticultural landscapes. Several species are known as aggressive root pathogens on both conifers and deciduous woody plants. Armillaria species are considered white rot fungi due to their capacity to degrade both lignin and cellulose in woody tissues. Armillaria mexicana was recently described as a new species found in peach (Prunus persica) orchards of Coatepec Harinas, State of Mexico. However, a subsequent study...AuthorsJane E Stewart, Mee-Sook Kim, Jorge R Ibarra Caballero, Patrick I. Bennett, John W. Hanna, Rubén D Elías-Román, Ned B.

- Although Armillaria solidipes was described in 1900, confusion has surrounded the appropriate use of this taxonomic epithet, largely because DNA sequence–based characterization and an associated culture were unavailable for the original holotype. An epitype for A. solidipes (previously known as North American Biological Species I) is established herein, along with morphological descriptions and genetic characterization that clearly distinguish A. solidipes, which is found in North America, from A. ostoyae (previously known as European Biological Species C), which is found in Eurasia.

- Nonmarket valuation surveys are designed to ask the who, what, when, where and why for a population of interest to understand preferences for environmental goods. Recent declines in survey response rates and high costs associated with traditional survey modes (e.g., mail), along with recent advances in online sampling have led to increased use of non-probability sample frames. This raises an important question for stated preference surveys about potential differences in willingness to pay (WTP) based on data collected by probability versus nonprobability samples. We develop a layered,...AuthorsAmila Hadziomerspahic, Sonja Kolstoe, Steven DundasSourceEPA National Center for Environmental Economics (NCEE) Working Paper SeriesYear2025
- This report presents a comprehensive social and economic monitoring plan and baseline assessment of the USDA Forest Service’s stewardship contracting program from 2014 to 2023. Stewardship contracting is a flexible tool that enables the Forest Service to achieve land management goals while working with non-federal partners and supporting local communities. The Ecosystem Workforce Program (EWP) at the University of Oregon, in partnership with the Forest Service, developed a national-level monitoring framework to evaluate the program’s effectiveness through ten key questions related to...AuthorsMichael R.

- 1. While collaborative science is becoming the norm in ecology, many ecologists participating in collaborations are less aware of the body of research that studies the processes by which collaborative teams organize and communicate.2. Here, we discuss how we successfully used a shared leadership model in the Dry Rivers Research Coordination Network. We discuss how this model promoted our success in different stages of the project, using the Tuckman model of team development: forming, storming, norming, performing and adjourning.3. Shared leadership in the forming phase helped us recruit a...AuthorsDaniel C. Allen, Amy J. Burgin, Erin C. Seybold, Walter K. Dodds, Michelle H. Busch, Anna Bergstrom, Corey A. Krabbenhoft, Kate S.

- Passive acoustic monitoring is an emerging approach in wildlife research that leverages recent improvements in purpose-made automated recording units (ARUs). The general approach is to deploy ARUs in the field to record on a programmed schedule for extended periods (weeks or months), after which the audio data are retrieved. These data must then be processed, typically either by measuring or analyzing characteristics of the audio itself (e.g. calculating acoustic indices), or by searching for some signal of interest within the recordings, e.g. vocalizations or other sounds produced by some...AuthorsZachary J.

- CO2 fertilization of the terrestrial biosphere is limited by nitrogen. Biological nitrogen fixation (BNF) is the dominant natural nitrogen source to the terrestrial biosphere and can alleviate nitrogen limitation but is poorly constrained in Earth system models (ESMs). Here, we compare terrestrial BNF from an ensemble of ESMs of the 6th Coupled Model Intercomparison Project to a new global synthesis of observations across natural and agricultural biomes. We find that compared to observations, ESMs underestimate agricultural BNF but overestimate natural BNF in the present day by over 50%....AuthorsSian Kou-Giesbrecht, Carla R. Reis Ely, Steven S.

- Aim: Surveying for a species of concern ahead of proposed activities that alter its habitat is routine practice in conservation and management. Such surveys may accumulate large datasets that could further elucidate trends in abundance and distribution. However, the as-needed surveying of proposed activities may impart a sample site selection bias on the data if used for another purpose. Management of a threatened, forest-nesting seabird offered an example of this. Here we assessed how resource management planning and survey requirements can bias clearance monitoring survey data collected...AuthorsRyan Baumbusch, Adam Duarte, James T.

- Motivation: SNAPSHOT USA is an annual, multicontributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of species interactions on daily activity patterns. Main Types of Variables Contained: SNAPSHOT USA 2019–2023 contains 987,979 records of camera trap image sequence data and...AuthorsRoland Kays, Michael V Cove, Alex Jensen, Benjamin R.

- The Northwest Forest Plan (NWFP) record of decision directs federal agencies to monitor the social and economic impacts of the NWFP in two ways: determine whether the supply of timber and nontimber resources is predictable and sustainable; and evaluate changes in local communities associated with federal forest management. The methodology for this 25-year NWFP report combines established practices for measuring timber and other forest resource supply trends with the application of novel social science research approaches. County-scale quantitative analysis of social and economic change...AuthorsElisabeth GrinspoonKeywordsSourceGen. Tech. Rep. PNW-GTR-1019.
