Such a root system can be generated using chemical root pruning by applying cupric carbonate (Cu) that can arrest the development of, or cause mortality to, root apical meristems resulting in the formation of new lateral roots with an overall increase in the biomass, length, and volume of the root system. Our objective was to investigate the effect of chemical...AuthorsAntonio Montagnoli, Kas Dumroese, Giulia Negri, Gabriella Stefania Scippa, Donato Chiatante, Mattia TerzaghiSourceNew Forests. 53: 1093-1112.Year2022
- More research on the above-ground compartment of plants has been completed compared to the belowground plant compartment. Much of this disparity is likely ascribable to the methodological difficulties of studying plant roots, the associated rhizosphere, and related traits (Freschet et al., 2021a). During the past two decades, a focus on methodological advancements has rendered root investigations more feasible and more standardized in terms of quantitative approaches (Bao et al., 2018; Montagnoli et al., 2018; Atkinson et al., 2019; Chiatante et al., 2019; Cabal et al., 2021; Freschet et...AuthorsAntonio Montagnoli, Donato Chiatante, Douglas L.

- Fire is an integral component of ecosystems globally and a tool that humans have harnessed for millennia. Altered fire regimes are a fundamental cause and consequence of global change, impacting people and the biophysical systems on which they depend. As part of the newly emerging Anthropocene, marked by human-caused climate change and radical changes to ecosystems, fire danger is increasing, and fires are having increasingly devastating impacts on human health, infrastructure, and ecosystem services. Increasing fire danger is a vexing problem that requires deep transdisciplinary, trans-sec...AuthorsJacquelyn K. Shuman, Jennifer K. Balch, Rebecca T. Barnes, Philip E.

- Forested watersheds provide many ecosystem services, such as the filtration of sediment, pollutants, and nutrients, which are increasingly threatened by wildfire. For example, stream nutrient concentrations often increase following wildfire and can remain elevated for decades, making downstream waters susceptible to eutrophication. We investigated the drivers of persistent elevated stream nutrients, specifically nitrate (NO3-), in nine watersheds that were burned 16 years prior by the Hayman fire, Colorado, USA. We evaluated the ability of multiple linear regression and spatial stream...AuthorsAllison E. Rhea, Timothy P. Covino, Charles C. Rhoades, Alexander C.

- Climate refugia, or places where habitats are expected to remain relatively buffered from regional climate extremes, provide an important focus for science and conservation planning. Within high-priority, multi-jurisdictional landscapes like the Madrean sky islands of the United States and México, efforts to identify and manage climate refugia are hindered by the lack of high-quality and consistent transboundary datasets. To fill these data gaps, we assembled a bi-national field dataset (n = 1416) for five pine species (Pinus spp.) and used generalized boosted regression to model pine...AuthorsSandra L.

- Rapid climate change over the coming century will impact suitable habitat for many tree species. In response to these changes in climate, areas that become unsuitable will see higher mortality and lower growth and recruitment. Therefore, early detection of demographic trends is critical for effective forest management. Recent 10-year remeasurement data from the United States (US) Department of Agriculture (USDA) Forest Service’s Forest Inventory and Analysis (FIA) Program’s national annual inventory of forest land provides an ideal data set for analyzing such trends over large areas....AuthorsKarin Kralicek, Tara M.

- Prescribed fire is increasingly being considered as a viable management tool by public and private land managers. Fully expanding prescribed fire use in a land management context, where it is an ecologically effective but not commonly applied tool, requires a comprehensive understanding of barriers that limit prescribed fire, especially in working rangelands of the North American Great Plains. While there is an emerging body of work on the perceptions of prescribed fire, there has yet to be a compilation of the research. We present a systematic review of the published literature on the...AuthorsAutumn S. Clark, Devan Allen McGranahan, Benjamin A. Geaumont, Carissa L. Wonkka, Jacqueline P. Ott, Urs P.

- This is the second paper of a two-part series on the barriers to prescribed fire use in the Great Plains of the USA. While the first part presented a systematic review of published papers on the barriers to prescribed fire use, specifically regarding perceptions and attitudes of land managers, this second part reviews the solutions that are employed to increase prescribed fire use by land managers in the Great Plains. First, the review compiled the solutions currently and ubiquitously employed to promote fire use and how they have been documented to address barriers. Second, potentially...AuthorsAutumn S.

- Climate change will continue to alter spatial and temporal variation in fire characteristics, or pyrodiversity. The causes of pyrodiversity and its consequences for biological communities are emerging as a promising research area with great potential for understanding and predicting global change. We reviewed the literature related to the causes and consequences of pyrodiversity over the 3-year period 2019-2021 to identify emerging themes and innovations.AuthorsGavin M. Jones, J.

- The ability of soil insecticidal drenches or spray-on insecticide/fungicide treatments to protect mass timber elements was assessed using two modified AWPA ground proximity tests established in 2017 and 2019. The 2017 test evaluated 3-ply Douglas-fir cross-laminated timber using a modified AWPA Standard E26 while the 2019 test used a modified AWPA E21 protocol to evaluate 3-ply Douglas-fir or southern pine cross-laminated timber as well as Douglas-fir mass plywood panels. Both tests were installed at the Harrison Experimental Forest (Saucier, Mississippi) and will be assessed for five...AuthorsMark E. Mankowski, Thomas G. Shelton, Grant T. Kirker, Jeffrey J.
