IPS typically have competitive advantage over native species due to traits such as earlier leaf out, prolific reproductive capability, and fewer natural predators. Thus, IPS can dominate a site and decrease the presence of native species, which affects biodiversity in the area.AuthorsLarissa Robinov, Cassandra KurtzSourceRes. Note NRS-313.

- Projected increases in wildfire frequency, size, and severity may further stress already scarce firefighting resources in the western United States that are in high demand. Machine learning is a promising field with the ability to model firefighting resource usage without compromising dataset size or complexity. In this study, the Categorical Boosting (CatBoost) model was used with historical (2012-2020) wildfire data to train three models that calculate predicted daily counts of 1) total assigned personnel (total personnel), 2) assigned personnel that are at the fire (ground personnel),...AuthorsKevin Young, Erin J.

- Background Understanding the role of fire in forested landscapes is fundamental to fire reintroduction efforts, yet few studies have examined how fire dynamics vary in response to interactions between local conditions, such as soil productivity, and more broadscale changes in climate. In this study, we examined historical fire frequency, seasonality, and spatial patterning in mixed conifer forests across a distinct gradient of soil productivity in the northern Sierra Nevada. We cross-dated 46 different wood samples containing 377 fire scars from 6 paired sites, located on and off of...AuthorsMichelle Coppoletta, Eric E. Knapp, Brandon M. Collins, Celeste S.

- Ground beetle (Coleoptera: Carabidae) species assemblages were studied at sites on the Huron-Manistee National Forests in Newaygo County, Michigan. The goal was to monitor changes in carabid diversity on areas where mature red pine (Pinus resinosa Sol. ex Aiton) was removed during the 1996–1997 winter and compare with carabid diversity at nearby natural dry sand prairie sites, natural oak-pine barrens, and uncut red pine stands. The red pine had been planted on dry sand prairie sites during 1940–1950. Sampling with pitfall traps occurred during May-August in both 1996 and 1997, but only...AuthorsRobert Haack, Toby R.

- Chipping and debarking of infested woody material such as branches and logs are common sanitation methods used to kill bark- and wood-infesting insects. The sixspined ips, Ips calligraphus (Germar), is a native North American bark beetle (Coleoptera: Curcu-lionidae: Scolytinae) that infests several pine (Pinus) species. We evaluated I. calligraphus mortality after debarking and grinding, using 12 recently cut longleaf pine (Pinus palustris Mill.) logs that had undergone natural colonization for three weeks in Florida. Initial bark beetle densities were estimated from samples collected the...AuthorsRobert Haack, Toby R. Petrice, John Foltz, Hui YeKeywordsSourceThe Great Lakes EntomologistYear2024
- Automated sorption balances are widely used for characterizing the interaction of water vapor with hygroscopic materials. These instruments provide an efficient way to collect sorption isotherm data and kinetic data. A typical method for defining equilibrium after a step change in relative humidity (RH) is using a particular threshold value for the rate of change in mass with time. Recent studies indicate that commonly used threshold values yield substantial errors and that further measurements are needed at extended hold times as a basis to assess the accuracy of abbreviated equilibration...AuthorsSamuel L.

- The primary objective of this study was to evaluate and compare the broad suitability of young Eucalyptus grandis W. Hill ex Maiden (EG), E. amplifolia Naudin (EA), Corymbia torelliana (F. Muell.) K.D.Hill & L.A.S. Johnson (CT), and Populus deltoides W. Bartram ex Marshall (PD) for making MDF by evaluating the basic wood properties of MDF produced from defibrillated Short Rotation Woody Crops (SRWC). Fast-growing EG, EA, CT, and PD may be deployed in SRWC systems in the lower Southeastern USA, especially in Florida. To evaluate these species for possible use as medium density fiberboard...AuthorsDonald L. Rockwood, Jerrold E. Winandy, Neil GribbinsKeywordsSourceBook chapterYear2024
- Lignin is a promising precursor to produce graphene materials due to its high carbon and aromatic contents. Upgrading lignin into graphene materials has gained significant interests as it offers a cost-effective and sustainable route to produce high-performance carbon materials. This review provides a comprehensive overview of the state-of-the-art technologies on lignin to graphene materials with a focus on thermal catalytic and photothermal upgrading. The applications of lignin-derived graphene materials and the perspectives for mass production of such graphene materials are also discussed.AuthorsHanwen Zhang, Qiangu Yan, Yucheng Peng, Zhiyong Cai, Caixia WanKeywordsSourceJournalYear2024
- Single Atom catalyst (SAC), a new frontier in heterogeneous catalyst design has evolved as a novel strategy to resolve the cost puzzle hindering the commercial scale applications of benchmark noble metal catalysts in various technologies. Downsizing expensive noble metal catalyst to atomically active centers have simultaneously reduced cost via enhanced atom utilization and maximized their catalytic activity and selectivity. However, taking full advantages of this novelty requires stabilization on appropriate support materials that provide adequate anchoring sites, promote strong metal...AuthorsPanesun Tukur, Frank Tukur, Yirong Mo, Qiangu Yan, Chaochao Dun, Jianjun WeiKeywordsSourceJournalYear2024
- Environmental pollution, particularly from heavy metals and toxic elements, poses a significant threat to both human health and ecological systems. While various remediation technologies exist, there is an urgent need for cost-effective and sustainable solutions. Biochar, a carbon-rich product derived from the pyrolysis of organic matter, has emerged as a promising material for environmental remediation. However, its pristine form has limitations, such as low adsorption capacities, a relatively narrow range of pH adaptability which can limit its effectiveness in diverse environmental...AuthorsNeda Arabzadeh Nosratabad, Qiangu Yan, Zhiyong Cai, Caixia WanKeywordsSourceJournalYear2024
