"Beetles don't get trees unless the trees are really water-stressed" and unable to make enough pinesap to defend themselves against the insects, he said. http://www.noticias.info/asp/aspComunicados.asp?nid=107739&src=0 These photos show the massive die-off of pinyon pines that occurred during a recent drought. Breshears, Neil Cobb, director of the Merriam-Powell Center for Environmental Research at Northern Arizona University in Flagstaff, Paul Rich, research scientist at Los Alamos National Laboratory (LANL) in N.M. and their colleagues reported their findings this week in the online Early Edition of the Proceedings of the National Academy of Sciences. In 1987, researchers established a study site in the pinyon-juniper woodland zone at LANL in northern N.M. They measured moisture and temperature of the location and used satellites to determine the extent of tree cover, according to Alan Tessier, program director in the National Science Foundation's division of environmental biology, which co-funded the research with several federal agencies. © D. Allen, U.S. Geological Survey The region's 60,000 square miles (about 155,000 square km) of pinyon-juniper woodlands became a lot less green starting in 2002, the team found. By the end of 2003, more than 90 percent of the pinyons in the study plot were dead. Breshears says such higher temperatures and drought are of the type predicted by climate-change models. The National Science Foundation (NSF), Los Alamos National Laboratory (LANL), the U.S. Forest Service, the U.S. Geological Survey, NASA and the National Institutes of Health funded the research. datos de la noticia Noticia nº: Ads by Google Douglas Fir Trees Pine Bark Beetle Spruce Trees Cedar Trees White Pine Trees 107739 10/12/2005 10:27 AM news - Heat and Drought Kills Trees in Southwest 3 of 4 Fuente : Marca Ciudad: País: Agencia emisora: Grupo Sección Subsección Fecha emisión: Fecha publicación: Tiempo de lectura http://www.noticias.info/asp/aspComunicados.asp?nid=107739&src=0 National Science Foundation (NSF) NSF Arlington Estados Unidos (no informado) Tecnología Ciencias Medios Ads by Goooooogle White Pine Trees Great deals on White Pine Trees Shop on eBay and Save! www.eBay.com Evergreen Trees Fast Growing Privacy Screens that take up very little yard space www.Fast-Growing-Trees.com 11/10/2005 11/10/2005 Pine Bark Beetles Products and information about pine bark beetles. 1 min www.GrowingLifestyle.com NCZ3 - publicidad << atrás | enviar | imprimir Últimas noticias de National Science Foundation (NSF) New Collaborations Tackle Biology's Perplexing Questions 11/10/2005 NSF Awards 19 New Projects to Better Understand Genetic Processes in Plants of Economic Importance 10/10/2005 New Grants Are Awarded to Inform the Public and Explore the Implications of Nanotechnology 10/10/2005 Solar Telescope Yields Striking New Sunspot Images 10/10/2005 Team Scores a Success in Protein Folding 10/10/2005 >> ver todas las anteriores agenda No hay actos de agenda nuevos convocatorias entrevistas No hay convocatorias nuevas No hay entrevistas de esta >> ver todas fuente 10/12/2005 10:27 AM news - Heat and Drought Kills Trees in Southwest 4 of 4 >> ver todas http://www.noticias.info/asp/aspComunicados.asp?nid=107739&src=0 >> ver todas << volver | portada | noticias de hoy NCZ2 publicidad White Pine Trees Great deals on White Pine Trees Shop on eBay and Save!
