Oberprieler, Ana Paula Ramos, Carlos Valente, Ana Reis, José Carlos Franco, Manuela BrancoAbstractThe study was initiated by the relative failure of the parasitoid Anaphes nitens in controlling the eucalypt weevil Gonipterus platensis on the Iberian Peninsula. Our aim wa...
Publication date: 1 July 2019Source: Forest Ecology and Management, Volume 443Author(s): Md. S. Newaz, Azim U. Mallik, Robert W. MackerethAbstractRecovery of understory vegetation after clearcut harvesting has received much attention but little is known about the recovery of riparian vegetation after forest harvesting along headwater streams, despite the critical role vegetation plays in the prote...
Dans l'archipel du Pacifique, l'essentiel des oiseaux autochtones a disparu. Ce sont désormais les nouvelles espèces introduites qui dispersent les plantes, tant bien que mal....
The concept of ecological integrity has been applied widely to management of aquatic systems, but still is considered by many to be too vague and difficult to quantify to be useful for managing terrestrial systems, particularly across broad areas. Extensive public lands in the western United States are managed for diverse uses such as timber harvest, livestock grazing, energy development, and wild...
Tropical forests Invasive Burmese pythons are still a problem in the Florida Everglades, as evidenced by the 17-foot (5.2-meter) snake found there recently (The New York Times, The Guardian). Brazil’s president sought support from the U.S. for his plans to “develop” the Amazon (Thompson Reuters). Successful restoration of landscapes depends on the inclusion of the […]...
The Science Framework is intended to link the Department of the Interior’s Integrated Rangeland Fire Management Strategy with long-term strategic conservation and restoration actions in the sagebrush biome. The focus is on sagebrush (Artemisia spp.) ecosystems and sagebrush dependent species with an emphasis on Greater sage-grouse (Centrocercus urophasianus). Part 1 of the Science Framework, pub...
Wild apple Malus sieversii (Ledeb.) M. Roem. (Rosales: Rosaceae), the ancestor of cultivated apples, is widely distributed in Central Asia and is recognized as an important germplasm bank. Recently, the invasive pest Agrilusmali Matsumura (Coleoptera: Buprestidae), originally distributed in eastern Asia, has damaged endemic apple forests in the Yili River valley, Xinjiang, China, and has spread ra...
National initiatives have emergedthat could benefit future establishment and management of nut production orchards. The 2008 and 2014 Farm Bills put forward agendas to address declining soil health on agricultural soils by promoting the use of cover crops to improve soil health during the fallow period in rotation with agronomic crops. Corn, wheat, and soybean yields have been increased by 2 to 4 ...
A remote island in the Caribbean could offer clues as to how invasive species are able to colonise new territories and then thrive in them, a new study suggests....
Sirex noctilio is an invasive woodwasp that, along with its symbiotic fungus, has killed pine trees (Pinus spp.) in North America and in numerous countries in the Southern Hemisphere. We tested a biological control agent in North America that has successfully controlled S. noctilio in Oceania, South Africa, and South America. Deladenus siricidicola nematodes feed on the symbiotic white rot fungus ...
Bugs such as the Winter moth and Asian Chestnut gall wasp are the bane of valuable trees and the people who rely on and benefit from them....
“Invasive insects and diseases pose both ecological and economic threats to our forest ecosystems,” says Qinfeng Guo, USDA Forest Service research ecologist. Guo is the lead author of a broad-scale study of U.S. forest data that examines the relationship between the number of native tree species and the number of nonnative forest pests. Across their […]...
