Abstract Background To increase ecosystem resilience and biodiversity, the maintenance and improvement of structural and compositional diversity of forests has become an important goal in forest management for many forest owners and jurisdictions. At the same time, future harvesting intensity (HI) may increase to meet the demand for ...
Ungulate carrion supports an unusual canine-corvid-eagle winter scavenging guild in northern Arizona. To evaluate the effect of location and habitat on carcass use and longevity, between December 1996 and April 2008 we recorded 870 observations of Bald Eagles (Haliaeetus leucocephalus), Common Ravens (Corvus corax) and coyotes (Canis latrans) scavenging 123 ungulate carcasses: 103 elk (Cervus cana...
<p>How fire interacts with an ecosystem is driven by forest structure, fuel bed heterogeneity, topography, and weather. The juxtaposition of two distinct vegetation types with divergent properties can further influence the effects of fire on an ecosystem. In the southeastern United States, pine flatwoods and hardwood–cypress swamps are distinct ecosystems that can be geographically intermi...
The type species of the genus, Epiceraticelus fluvialis Crosby & Bishop, 1931, is herein redescribed since the types are presumed lost. In addition, a new species, Epiceraticelus mandyae n. sp., from the Southeastern United States is described....
Abstract American chestnut (Castanea dentata) was a foundation species in the eastern United States until chestnut blight (Cryphonectria parasitica) infestation resulted in range-wide catastrophic reduction. Since 1983, The American Chestnut Foundation (TACF) has engaged in a breeding program aimed at restoring C. dentata to the wild. The primary goal has been to introduce blight...
Sonae Arauco’s Three Dimensional Fiberboard (3DF) and a research project which harnessed bio technologies to create sequins from naturally abundant wood-derived cellulose have been named the winners of the TTJ Timber Innovation Award 2019.

¿Cómo deforestar y no ir a la cárcel? Las autorizaciones de cambio de uso y desbosque en el Perú.Hugo Che Piu DezaPresidente de DARMiembro de la RELADEFAAhora que estamos todos preocupados por las quemas y los incendios forestales en la Amazonía, solemos pensar que está prohibido deforestar, es decir, eliminar la cobertura forestal de un bosque natural. Sin embargo, el marco legal peruano si...
Big changes are needed to farm subsidies, but there will always be targeted support to certain sectors and farm types, writes Richard HarveyIt is impossible to disagree with the Food and Land Use Coalition report’s findings ($1m a minute global farm subsidies ‘are destroying the world’, 16 September). Yet it would be wrong to dispense with all agricultural support programmes, particularly in...
*Key message Agrilus macer is attacking sugarberry trees in the southeastern USA, a region from which few specimens have been previously collected. Despite attacking at high densities, this species appears to be a secondary pest, and there is no evidence it carries harmful fungal pathogens. * Context Because the genus Agrilus Curtis includes significant forest pests, the association of a poorly kn...
Sirex noctilio F. (Hymenoptera: Siricidae) is a major exotic pest of pines (Pinus spp.) in the Southern Hemisphere and has become established in northeastern North America. We investigated the suitability of bolts of six economically and ecologically important U.S. pine species grown in the southeastern United States, including eastern white (P. strobus L.), loblolly (P. taeda L.), longleaf (P. pa...
A popular group of pesticides linked to huge declines in bees around the globe could be adversely affecting migratory birds making pit stops on farmlands, according to new research. In the study, wild white-crowned sparrows (Zonotrichia leucophrys) exposed to seeds treated with imidacloprid, a neonicotinoid insecticide, suffered considerable weight loss and delayed the timing of their […]...
