“…While an increase in live oak is generally viewed positively due to its high preference as browse forage by goats in this region (Taylor and Kothmann 1990) and aesthetic appeal (Kreuter et al 2004), large populations of live oak are currently being crippled in Texas by Ceratocystis fagacearum, a fungal pathogen that causes oak wilt (Appel 1995;Koch et al 2010). An increase in the density and regeneration of live oak has led to highly interconnected root systems that facilitate the spread of oak wilt through common root systems and root grafts (Juzwik et al 2008;Koch et al 2010). Reducing current live oak densities or maintaining densities at presettlement levels is therefore a high priority (Koch et al 2010).…”

We examined how the occurrence and structure of grasses and woody plants changed after 12 yr of a fire season manipulation and removal of livestock herbivores. Applying high intensity fires in the summer preserved the structural integrity of this semiarid live oak (Quercus virginiana Mill.) savanna while decreasing or eliminating numerous problematic plants in the understory and overstory, such as prickly pear cactus (Opuntia spp.), sacahuista (Nolina texana S. Watson), Ashe juniper (Juniperus ashei J. Buchholz), Pinchot's juniper (J. pinchotii Sudw.), and honey mesquite (Prosopis glandulosa Torr.). In the less intense repeat winter burning treatments, undesirable woody plants were generally maintained at pretreatment levels in the overstory but all woody plants except Ashe juniper increased in the understory. Alternatively, areas excluded from fire in the control treatment rapidly transitioned from a grass-tree codominated savanna environment to one that is heavily dominated by woody plants. In the grass community, the most frequently occurring grass species in the winter burn treatment differed from summer burn and control treatments, whereas the summer burn treatment was not different from the control. Of the herbaceous plants, only little bluestem (Schizachyrium scoparium [Michx.] Nash) responded to fire treatments. Little bluestem increased in the winter burn treatment, remained fairly constant in the summer burn treatment, and decreased in the control. Other grasses varied largely as a function of annual weather variability, the removal of livestock, and legacy effects resulting from pre-existing variability. These findings suggest that fire can reduce or eliminate woody plant species that threaten the stability of live oak savannas while having little long-term effect on grasses desired by rangeland managers. Resumen Examinamos el cambio que hubo en la ocurrencia y estructura de gramíneas y plantas leñ osas después de 12 añ os de manipulación de la época del fuego y exclusión del pastoreo por el ganado. Por medio de la aplicación de alta intensidad de fuego durante el verano se preservó la integridad estructural de estas sabanas semiáridas de encino (Quercus virginiana Mill.) mientras decrecieron o se eliminaron una gran cantidad de plantas problemáticas que se ubican arriba y abajo de la cobertura arbórea, tales como especies de nopales (Opuntia spp.), sacahuista (Nolina texana S. Watson), Ashe juniper (Juniperus ashei J. Buchholz), Pinchot's juniper (J. pinchotii Sudw.), y mezquite (Prosopis glandulosa Torr.). En las áreas tratadas con fuegos de menor intensidad y repetidamente durante el invierno, las plantas leñ osas indeseables se mantuvieron generalmente en niveles existentes a antes de la aplicación de las quemas en la cobertura aérea, pero todas las plantas leñ osas excepto Ashe juniper se incrementaron en los lugares debajo de los árboles. Por otra parte, las áreas excluidas del fuego en los tratamientos que se usaron como controles cambiaron rápidamente pasando de ambientes dominados por pastos-á...

In this study, the use of biorefined wood materials in the fabrication of organic redox supercapacitors is proposed. Oak‐derived hard carbon (HC) is revealed to have a nanographite domain structure, showing conductivity as high as that of artificial graphite. The CO2‐activated hard carbon (A–HC) has a conductivity one order higher than that of commercial activated carbon, with a surface area of 1126 m2 g−1. The energy densities of supercapacitors composed of a tetrachlorohydroquinone cathode and anthraquinone (AQ) or 1,5‐dichloroanthraquinone (DCAQ) anode are 19.0 and 13.8 Wh kg−1, respectively. The utilization rate of AQ with A–HC is 97.6% (250.9 mAh g−1), which is much higher than those in previous reports (≈80%). After 1000 cycles, 91.0% of the discharge capacity is retained when the DCAQ anode is used. Biorefined wood materials lead to a remarkable improvement in the operation of organic supercapacitors. This is intriguing, because the functional carbon material herein is easily prepared from a natural resource, wood, whereas numerous studies have prepared such materials from artificial chemical sources. Therefore, the use of oak‐derived HC enhances the usability of organic active materials for energy storage devices and potentially has a far‐reaching impact on the environment.

“…Concern regarding the destructive nature of oak wilt has resulted in numerous programs to prevent new infections and manage expanding epicenters. Prevention of overland spread is considered highly effective 9 . This strategy requires identifying a high-risk time period, typically April–July in the Midwestern US, when nitidulid beetles are actively flying and infecting trees 10 .…”

We assess risks posed by oak wilt—a disease caused by the fungal pathogen Bretziella fagacearum. Though not currently found in Canada, our distribution models indicate that suitable climate conditions currently occur in southern Ontario for B. fagacearum and two of its main insect dispersal vectors, Colopterus truncatus and Carpophilus sayi. Climate habitat for these species is projected to expand northward under climate change, with much of the oak range in eastern Canada becoming climatically suitable within the next two decades. Potential costs for the removal and replacement of oak street trees ranged from CDN$266 to $420 million, with variation related to uncertainty in costs, rate of tree replacement, and city-level estimates of oak street tree density. The value of standing oak timber in eastern Canada was estimated at CDN$126 million using provincial stumpage fees and as a CDN$24 million annual contribution to national Gross Domestic Product (GDP) when calculated using a combination of economic and forestry product statistics. These values can help inform the scale of eradication and/or management efforts in the event of future oak wilt introductions.
