Innovative Approaches To Estimating Sessile Oak Stem Volume: Comparing Additive Models And Ensemble Machine Learning, Maria J. Diamantopoulou, Abbas Şahi̇n, Ramazan Özçeli̇k

Turkish Journal of Agriculture and Forestry

Sessile oak is an important deciduous forest tree species across Türkiye and Europe. Estimating individual tree and stand volumes is essential for growth and yield models, as these predictions play a critical role in assessing forest management, economics, and fire risk. In pursuit of this goal, nonlinear seemingly unrelated regression (NSUR) was used for the simultaneous fitting of stem volume components, and compared to three ensemble machine learning techniques: gradient boosting regression (GBr), XGBoost regression (XGBr), and random forest regression (RFr). NSUR accounts for correlations between error terms across different equations, leading to more efficient parameter estimates than if each …

Tracing Priming Effects In Palsa Peat Carbon Dynamics Using A Stable Isotope-Assisted Metabolomics Approach, Christian Ayala-Ortiz, Moira Hough, Elizabeth K. Eder, David W. Hoyt, Rosalie K. Chu, Jason Toyoda, Steven J. Blazewicz, Patrick M. Crill, Ruth Varner, Scott R. Saleska, Virginia I. Rich, Malak M. Tfaily

Michigan Tech Publications

Introduction: Peatlands store up to a third of global soil carbon, and in high latitudes their litter inputs are increasing and changing in composition under climate change. Although litter significantly influences peatland carbon and nutrient dynamics by changing the overall lability of peatland organic matter, the physicochemical mechanisms of this impact—and thus its full scope—remain poorly understood. Methods: We applied multimodal metabolomics (UPLC-HRMS, ¹H NMR) paired with ¹³C Stable Isotope-Assisted Metabolomics (SIAM) to track litter carbon and its potential priming effects on both existing soil organic matter and carbon gas emissions. Through this approach, we achieved molecule-specific tracking …

Early Detection Of Oak Wilt Using Unmanned Aerial Vehicles (Uav) & Computer Vision, Muttaki I. Bismoy

Masters Theses

Forests are critical ecosystems, delivering services such as biodiversity conservation, climate regulation, timber production, and recreation. However, they face increasing threats from pathogens like Bretziella fagacearum, which causes Oak Wilt, a lethal disease that disrupts water transport in oak trees, leading to canopy dieback and eventual death. Traditional detection methods rely on manual ground surveys, which are labor-intensive, time-consuming, and prone to error, particularly in early disease stages.

This research presents an automated, scalable, high-precision Oak Wilt detection system using Unmanned Aerial Vehicles (UAVs) combined with deep learning-based computer vision. Expanding on earlier work with a lightweight CNN achieving an …

Periodic Evaluations Indicate Increased Effectiveness Of Oregon Master Woodland Manager Volunteer Program, Alicia Christiansen, Lauren Grand, Norma Kline, Tiffany Hopkins

Journal of Extension

The Oregon State University Extension Service Master Woodland Manager (MWM) volunteer program trains landowners in core forestry and natural resource topics. Landowners participate in the MWM program to increase their forest management knowledge, improve their own management practices, and prepare them to volunteer in their community (Bowers, 2000). We surveyed MWM volunteers to understand the effectiveness of the program and what barriers exist to volunteering. Volunteers find the program to be increasingly adequate for personal management and answering questions, but time continues to be the biggest barrier for completing required volunteer hours.

Breeding Season Bird Use Of And Non-Native Plants Found In Food Plots In The Southern Appalachian Mountains, Nathan A. Klaus, Kirk Stodola

Georgia Journal of Science

Traditional agricultural style food plots, or wildlife openings, are widely used for wildlife management and hunting opportunities on public and private lands in the Southeastern United States. These habitats are often cited as beneficial for game and nongame wildlife, but there are few published studies examining nongame bird use of food plots in recent decades. Modern concerns about the ecological costs of food plots, particularly fragmentation and invasive non-native species, warrant a new examination of this practice. We conducted avian surveys during the breeding season of 2008 at 39 sites composed of three different treatments: traditional food plots, novel food …
