Little is known about space use of the near threatened Kirtland’s Warbler (Setophaga kirtlandii) wintering in The Bahamas, and how the warbler’s home range size and core area overlap among individuals and vary with sex and age, food availability, winter season, and habitat characteristics. To address these knowledge gaps, we used radio telemetry to determine sedentary home range size (95% adaptive kernel), core area (50% AK), and overlap for 27 radio-tagged warblers during two winters on...AuthorsJoseph M.

- Change in land use and land cover (LULC) is crucial to freshwater ecosystems as it affects surface runoff, groundwater storage, and sediment and nutrient transport within watershed areas. Ecosystem components such as wetlands, which can contribute to the reduction of water pollution and the enhancement of groundwater recharge, are altered by LULC modifications. This study evaluates how wetlands in the Big Sunflower River Watershed (BSRW) have changed in recent years and quantified their impacts on streamflow, water quality, and groundwater storage using the Soil and Water Assessment Tool...AuthorsDipesh Nepal, Prem Parajuli, Ying Ouyang, Filip To, Nuwan Wijewardane, Vivek VenishettySourceResourcesYear2024
- We analysed data from 25 mammal species recorded by camera traps at 6645 locations across the conterminous United States in a joint modelling framework to estimate relative abundance of each species. We then used a clustering analysis to describe 8 broad and 16 narrow mammal communities. Climate was the most important predictor of mammal abundance overall, while human population density and agriculture were less important, with mixed effects across species. Seed production by forests also predicted mammal abundance, especially hard-mast tree species. The mammal community maps are similar...AuthorsRoland Kays, Matthew H.

- Climate change is bringing rapid changes to the environment, including new temperature ranges and precipitation regimes. Some trees may no longer thrive and regenerate in their current locations, which in turn may reduce the ecosystem goods and services they have produced in the past.AuthorsNorthern Research Station USDA Forest ServiceKeywordsSourceFSYear2024
- Thermally modified woods are a nascent but growing industry in North America, which has seen an increase in both the number of producers as well as annual board footage of material produced. These products are being marketed as a sustainable alternative to tropical hardwoods in areas of non-structural, above ground application. The AWPA P9 committee (non-biocidal wood protection) is responsible for the establishment of Task Groups to consider nonbiocidal wood protection methods and the development of protocols for standardization. Thermally modified wood has been a continual action item on...AuthorsMatt Aro, Mike Barnes, John Heyesen, Kelly Bartz, Glenn Larkin, Mark E. Mankowski, Rachel A. Arango, Grant T.

- This research evaluated the mechanical and physical properties of three underutilized hardwood species according to visual lumber grades. Findings are discussed in relation to the requirements recommended such as density, modulus of rupture (MOR), and modulus of elasticity (MOE) for the manufacture of cross-laminated timber (CLT) industrial mats, which is a potential end use of low-valued hardwood species. Results showed that all species tested had an average MOE greater than that required for CLT lumber. Visual grading was an important component in strength determinations as evidenced by...AuthorsMercy Ogunruku, Tamara S. F. A. França, Frederico J. N. França, R. Daniel Seale, Rachel A.

- As the demand for sustainable energy and the importance of tocopherol increase, this study investigates the large-scale process model, economic analysis, optimum profitability scenario, and life cycle assessment of an integrated biodiesel production and tocopherol separation process using rapeseed oil deodorizer distillate. The primary objective is to evaluate the economic and environmental sustainability of this integrated approach. A large-scale process model was developed based on experimental data from the literature, and comprehensive assessments of technical and economic performance,...AuthorsNaveenkumar Rajendiran, R.B.

- In 2015, the U.S. Department of Agriculture, Forest Service, Forest Inventory and Analysis program collected forest and tree measurements from 37 plots among three forest communities on the islands of Rota, Saipan, and Tinian in the Commonwealth of the Northern Mariana Islands (CNMI). A total of 36 tree species and 132 dominant vascular plant species were recorded, including 28 invasive species. Invasive plant species covered most of the forest area, and 9 of the top 20 most dominant nontree plant species were invasive. The small tree Leucaena leucocephala (tångantångan), comprising by far...AuthorsJulian Dendy, Olaf Kuegler, Ashley Lehman, Victor D. GuerreroSourceGen. Tech. Rep. PNW-GTR-1028.

- Applications of deep eutectic solvent (DES) systems to separate lignocellulosic components are of interest to develop environmentally friendly processes and achieve efficient utilization of biomass. To enhance the performance of a binary neutral DES (glycerol:guanidine hydrochloride), various Lewis acids (e.g., AlCl3⋅6H2O, FeCl3⋅6H2O, etc.) were introduced to synthesize a series of ternary DES systems; these were coupled with microwave heating and applied to moso bamboo. Among the ternary DES systems evaluated, the FeCl3-based DES effectively removed lignin (81.17%) and xylan (85.42%),...AuthorsYingying Feng, Thomas L.

- Prior to use or sale, new termiticides must undergo a standardized test — and those efficacy data are subsequently submitted to the U.S. Environmental Protection Agency (EPA). The EPA has a specific methodology that is required for testing, and the agency relies on the U.S. Department of Agriculture (USDA) Forest Service (FS) Forest Products Laboratory Durability and Wood Protection unit to do the work. These data are used to determine whether tested concentrations, applied in the studies as a zone of treated soil, are effective at preventing damage to test wood blocks in three field...AuthorsThomas G.
