- Locational errors and sampling bias may produce unrepresentative species distribution models. To decompose the influence of errors, I modeled species distributions of 31 mammal species from georeferenced records and random samples from range maps, with potential sources of errors added or removed, using the random forests algorithm. Errors included the addition of (1) cities, (2) administrative centers, (3) records flagged as potential errors (e.g., outliers), and (4) urban records to range map samples; the removal of (5) flagged records and (6) urban records from georeferenced records;...AuthorsBrice HanberrySourceLand. 14(8): 1620.Year2025
- Euro-American settlement entailed comprehensive vegetation clearing and fire exclusion, with attendant decreases in fire-tolerant oak and pine tree species and open conditions throughout the southeastern and central eastern United States. While historical tree data are locked in individual land deeds for part of the eastern United States, two assessments during 1900–1909 provided historical tree composition in the southern Appalachian region, primarily in North Carolina. According to assessments during 1900–1909, fire-tolerant oaks and American chestnut (Castanea dentata) were the dominant...AuthorsBrice Hanberry, J.

- Wildfires can lower soil carbon (C) stocks directly through combustion, but also indirectly during post-fire recovery if microbial C demands outpace photosynthetic C inputs. However, how much C is respired by soil microorganisms post-fire may depend on wildfire effects on particulate organic carbon (POC; mostly plant material accessible to microbes) and/or mineral-associated organic carbon (MAOC; considered C protected by minerals from decomposers), meaning assessment of wildfire impacts on these pools is necessary to predict microbial decomposition rates and, thus, the fate of soil C....AuthorsAlexander Krichels, Elizah Z.

- The U.S. Department of Agriculture (USDA), Forest Service, Forest Inventory and Analysis (FIA) program provides this resource update yearly as an overview of forest resources in Idaho. These estimates are derived from field data collected across a systematic network of fixed-radius forest monitoring plots located on both public and private land. New updates are provided annually as a subset of plots within the State are remeasured. Each year, field crews visit and measure a subset of all FIA plots across the entire State (the size of the subset varies by State and year). Combining all the...AuthorsForest Service.

- Environmental observation networks, such as AmeriFlux, are foundational for monitoring ecosystem response to climate change, management practices, and natural disturbances; however, their effectiveness depends on their representativeness for the regions or continents. We proposed an empirical, time series approach to quantify the similarity of ecosystem fluxes across AmeriFlux sites. We extracted the diel and seasonal characteristics (i.e., amplitudes, phases) from carbon dioxide, water vapor, energy, and momentum fluxes, which reflect the effects of climate, plant phenology, and ecophysiol...AuthorsDavid E Reed, Housen Chu, Brad G.

- Successive catastrophic wildfire seasons in western North America have escalated the urgency around reducing fire risk to communities and ecosystems. In historically frequent-fire forests, fuel buildup as a result of fire exclusion is contributing to increased fire severity. The probability of high-severity fire can be reduced by active forest management that reduces fuels, prompting federal and state agencies to commit significant resources to increase the pace and scale of fuel reduction treatments. However, lower severity areas of wildfires also have the potential to act as “treatments,”...AuthorsKristen L. Shive, Clarke A. Knight, Zachary Steel, Charlotte K. Stanley, Kristen N.

- Using mark-resight data, we investigated fidelity to territory and mate as well as breeding dispersal rates and the causes and consequences of breeding dispersal in a 20-year study of American goshawks (Astur atricapillus) in Arizona, USA. Generalized Additive Mixed Models were used to identify the relative contributions of four prominent explanatory variables (eggs laid, nest failed, nest successful, mate loss) and 21 individual and environmental variables in a machine learning Conditional Inference Forest to predict breeding dispersal. Ninety-five percent of males and 92% of females...AuthorsRichard T. Reynolds, Shannon Kay, Jeffrey Lambert, Martha EllisSourcePLoS One. 20(5): e0323805.Year2025
- In Idaho, the Boise Basin, Deception Creek¸ and Priest River Experimental Forests (EFs) were established in 1911 and 1933 to facilitate long-term scientific research on multiple aspects related to forest management and ecology. Nestled within them are the Canyon Creek, Montford Creek, Bannock Creek, and Wellner Cliffs Research Natural Areas established in 1937, 1970, and 2004 to serve as reference areas for research, education, and monitoring of intensive management actions. Collectively, this network has advanced our knowledge on the species, distributions, and ecology of lichens,...AuthorsJames B. Donley, Andrea Pipp, Jason R. ReinhardtKeywordsSourceEvansiaYear2025
- Root diseases are a major cause of conifer damage in forests of western North America. Two major root diseases in the region, which are caused by native pathogens, are laminated root rot (LRR) disease of Douglas-fir (Pseudotsuga menziesii) caused by Coniferiporia sulphurascens (Agne et al. 2018; Lockman and Kearns 2016; Thies and Sturrock, 1995), and black stain root disease (BSRD) caused by three fungal pathogens: Leptographium wageneri on single-leaf pinyon pine (Pinus monophylla) and pinyon pine (P. edulis), L. ponderosum on ponderosa pine (P. ponderosa) and Jeffrey pine (P. jeffreyi),...AuthorsDuncan R.

- Western white pine (WWP; Pinus monticola) is a keystone species in temperate, moist forests of western North America, where it displays adaptation to a range of climates and resilience to native root diseases (e.g., Harvey et al. 2008). Since Cronartium ribicola, the cause of white pine blister rust (WPBR), was introduced to North America in the early 1900s, WPBR has become well established and caused a dramatic reduction of WWP across its range (e.g., Neuenschwander et al. 1999; Harvey et al. 2008). Over recent decades, casual observations have indicated that WPBR incidence rates may be...AuthorsMee-Sook Kim, Jane E. Stewart, Marcus V. Warwell, John W. Hanna, Paul J.
