Bulletin of Chinese Academy of Sciences (Chinese Version)
Addressing the current limitations in forestry and grassland research, particularly in cross-scale system cognition, complex process mechanism representation, and multi-scenario simulation, this study proposes an artificial intelligence-driven paradigm reconstruction framework, to shift the research model from experience-oriented approaches toward data- and intelligence-driven integration. On this basis, the study systematically establishes a multidimensional mapping between artificial intelligence and forestry and grassland research across research objects, processes, and objectives, and clarifies their intrinsic coupling mechanisms and technical pathways. Furthermore, it develops a foundational capability system to support the new paradigm from four key dimensions: data, computing power, models, and applications. By examining …

Michigan Tech Publications
Methane (CH4) is a potent greenhouse gas, and tropical forests account for roughly one–third of global atmospheric CH4 uptake by soils. Projected warming and more frequent hurricanes in these ecosystems may alter soil CH4 sink strength, as warmer and wetter soils enhance methanogenesis activity. We measured soil CH4 and CO2 efflux during the calendar summer months of 2023 and 2024 alongside continuous records of soil moisture, soil and air temperature, and precipitation in an in–situ warming experiment (TRACE) located in a lowland tropical forest in Puerto Rico, six to seven years after Hurricanes Irma and Maria (2017). The realized warming …

Financial Analysis Tool (Ct-Ft) For Western North Carolina Christmas Tree Growers, Sam Blumenfeld, Solomon Ghezehei, Justin G.A. Whitehill, Elizabeth G. Nichols
Journal of Extension
Western North Carolina is a major national Christmas tree (CT) production region, yet the CT industry faces numerous challenges that threaten its financial sustainability. Little economic research has been done, and limited decision-making tools exist to assist producers, Extension agents, and associated industry stakeholders. We developed an Excel-based financial analysis tool (CT-FT) to assist small and midsize wholesale CT producers in operational planning and financial assessment. The publicly available financial tools will enable CT growers to better understand their finances and operations, interact with financial stakeholders, assess alternative management scenarios, and track yearly costs to improve operational financial sustainability.

Half of the aboveground biomass in forests is stored in a disproportionately small number of very tall trees. These giants are predicted to be more vulnerable to drought-induced damage because height impairs their hydraulic system. We evaluated whether the hydraulic system of world’s tallest tropical tree species—Southeast Asian dipterocarps—are negatively affected by their height. The more negative xylem pressures caused by tree height were fully compensated for through adjustment of vessel anatomy and leaf hydraulic traits, and the trees suffered no height-related loss in growth during a severe drought. Therefore, height does not make the hydraulic systems of the world’s …

Distribution And Impact Of Cogongrass (Imperata Cylindrica) In Northern Mississippi, Carl R. Pulver V, Ryan E. Burke, Elizabeth Esser, Evan Moore, Ashley Schulz
Endeavors: Mississippi State Undergraduate Research Journal
Cogongrass (Imperata cylindrica) is a non-native, rhizomatous grass that has invaded the southeastern United States. It forms dense mats that outcompete native plants, alters decomposition and microbial assemblages, and has highly flammable litter that alters fire behavior, affecting native plant communities. Though surveys for cogongrass have been conducted in southern Mississippi, the degree of cogongrass infestations in northern Mississippi has remained unclear and concerning. This study aimed to update cogongrass location data for the state and identify problem areas to guide state invasive plant management efforts. To provide a starting point, previously documented cogongrass locations were synthesized from natural history …
