Monumental chestnut trees: source of genetic diversity, cultural and landscape value
2019
The mtonumental trees are unique individuals tof venerable age and ctonsiderable size, which represent a heritage tof inestimable histtorical, cultural, landscape, and scientific value ftor the territtory. They alsto ctonstitute a stource tof genetic diversity which ctonfers them ltongevity and ability tto adapt tto climate and envirtonmental changes. In this ctontext, studies ton centennial trees can be useful ftor interpretatiton tof species histtory as migratiton events, selectiton and anthrtoptogenic actiton. The aim tof this research was tto evaluate the genetic variability tof ancient Castanea sativa trees and relate them tto actual natural/naturalized ptopulatitons and varieties in t…
Application and evaluation of biomagnetic and biochemical monitoring of the dispersion and deposition of volcanically-derived particles at Mt. Etna, …

article i nfo Article history: Received 6 August 2009 Accepted 4 January 2010 Available online xxxx Biomagnetic monitoring, using tree leaves as passive surfaces for particle collection, has been shown to be a promising technique for assessing the dispersion and deposition of particles in the context of anthropogenic pollution. By comparing leaves' magnetic properties with trace metal levels measured in the leaves, we here assess the utility of the biomagnetic technique as a sensitive, fast and inexpensive method for assessment of volcanic plume deposition. Samples of sweet chestnut leaves (Castanea sativa) were collected from the area surrounding Mt. Etna volcano in Sicily during the 2008 …

Este artículo presenta los resultados paleoambientales de los primeros análisis palinolójicos y sedimentológicos llevados a cabo en el area de Tulle (Mars, Gimel-les-Cascades, Corrèze, Francia). Se basan en la comparación de distintos indicadores bióticos (polen, microfósiles no polínicos) y sedimentarios y en la realización de 9 dataciones radiocarbónicas. Esta investigación establece datos inéditos sobre las dinámicas paisajísticas desde la Antigüedad y sus factores de control tanto climáticos como antrópicos. También analiza de que manera estos cambios paisajísticos pueden significar el desarrollo de sistemas de uso diversificados de los recursos vegetales como el cultivo del castaño (Ca…
