Displaying 4,501 - 4,510 of 65,096 Publications- Objective. "Nature prescriptions" are increasingly being adopted by health sectors as an adjunct to standard care to attend to health and social needs. We investigated levels of need and interest in nature prescriptions in adults with cardiovascular diseases, psychological distress and concomitants (e.g. physical inactivity, sedentary behaviour, obesity, loneliness, burn-out). Methods. A nationally-representative survey of 3,319 adults across all states and territories of Australia was completed in February 2021 (response 84.0%). Participants were classified across 15 target groups using...AuthorsThomas Astell-Burt, J.

- The establishment of monoculture plantations of non-native tree species is a common practice for supplementing native timber stocks. Since native wildlife species may lack co-evolved traits needed to successfully exploit nonnative tree species, non-native plantations are expected to provide inferior habitat for native biodiversity. However, some studies report that plantations may increase net biodiversity at the landscape scale by introducing novel habitats or supplementing existing natural forests. We used point counts to sample birds in 2016 and 2017 in mature Norway spruce (Picea...AuthorsCalvin Ritter, David King, Stephen DeStefano, Daniel ClarkKeywordsSourceForest Ecology and ManagementYear2023
- Avian species provide pest control services in some agricultural systems, which may incentivize farmers to conserve natural habitats for native biodiversity. A critical component of this equation, however, is verifying that avian species are consuming potential pest species in the agricultural ecosystems. We used a DNA metabarcoding approach to determine the frequency of pest presence in songbird fecal samples collected from birds caught on diversified, low-intensity farms in New England, USA, during the bird breeding season. Twelve species of insect pest were identified in fecal samples,...AuthorsSamuel J. Mayne, David King, Jeremy C. Andersen, Joseph S. ElkintonKeywordsSourceGlobal Ecology and ConservationYear2023
- Recolonization of the Cascade Range in southern British Columbia, Canada, and Washington, USA, by wolverines (Gulo gulo (L., 1758)) is an ongoing process whose ultimate outcome is unknown. A reliable species distribution model for the wolverine in the Cascades (i.e., their first-order habitat selection) is urgently needed to help inform management and conservation strategies. Using Argos location data obtained on 10 resident adult wolverines (six females, four males) from 2008 to 2016, we generated a multi-covariate species distribution model for the wolverine in the Cascades. Our final...AuthorsKeith B. Aubry, Catherine M. Raley, Andrew J. Shirk, Kevin S. McKelvey, Jeffrey P. CopelandKeywordsSourceCanadian Journal of Zoology. 101(2): 95-113.Year2023
- The Timber Products Output (TPO) survey is used to determine industrial uses of roundwood, reporting on volumes of roundwood received and residues generated by the primary forest industry by tree species and counties of harvest. This knowledge aids stakeholders in making informed decisions about available forest resources and/or harvest intensity. The widespread use of TPO estimates makes it important to understand the scale and scope of missing data in the survey. This first attempt analyzed respondent-level and question-level nonresponse (RLNR and QLNR, respectively) for Northern and...AuthorsMarla Markowski-Lindsay, Consuelo Brandeis, Brett J.

- There is need for well-defined lignin macromolecules for research related to their use in biomaterial and biochemical applications. Lignin biorefining efforts are therefore under investigation to meet these needs. The detailed knowledge of the molecular structure of the native lignin and of the biorefinery lignins is essential for understanding the extraction mechanisms as well as chemical properties of the molecules. The objective of this work was to study the reactivity of lignin during a cyclic organosolv extraction process adopting physical protection strategies. As references,...AuthorsMaria Karlsson, Joakim Romson, Thomas Elder, Åsa Emmer, Martin LawokoSourceBiomacromoleculesYear2023
- A high-resolution differential mobility analyzer (DMA) is used for the first time to study the mobility distribution of Polystyrene Latex (PSL) particles. We investigate in particular some unique, nominally 200 nm and 100 nm PSL particles, known by other methods to be unusually monodisperse. The suspensions are electrosprayed after adding ammonium acetate to a concentration of 10 mmol/L. Mobility analysis is carried out after charge reduction with a second electrospray of the opposite polarity. The 200 nm particles typically produce two narrow peaks, with relative intensities that depend...AuthorsJuan Fernandez de la Mora, John Kramar, Natalia Farkas, Steven Papanu, Robert DanaKeywordsSourceJournal of Aerosol ScienceYear2023

- In recent years, environmental stewardship has been emphasized as one solution to social-ecological sustainability concerns, especially at the local scale. The Stewardship Mapping and Assessment Project (STEW-MAP) is a national research program developed by the USDA Forest Service that has been implemented at numerous locations in the United States and internationally. This study compared the mission statements of environmental stewardship groups in the Los Angeles River Watershed to previously proposed definitions and frameworks of organizational environmental stewardship to see how well...AuthorsAlyssa Thomas, Michele RomoliniKeywordsSourceAmbio. 52(6): 1137-1150Year2023
- Lignin is one of the three structural components of lignocellulosic biomass and the only renewable source for sustainably producing aromatic chemicals. Despite lignin’s promise for targeted valorization to fine chemicals, fuels, and polymer composites, a major roadblock is an ambiguity associated with its molecular structure. Due to the lack of an established molecular structure, all types of computational studies from reaction mechanism to reaction energetics are performed with model lignin compounds. Among several thermochemical conversion techniques, lignin pyrolysis has been an active...AuthorsTanzina Azad, Maria L. Auad, Thomas Elder, Andrew J. AdamczykKeywordsSourceEnergy & FuelsYear2023
