This paper discusses dendrochronology as the classic method of analysing width of tree rings, and its application to the study of the impact on Earth of an extraterrestrial object. The paper also provides a brief historical notation on the Italian contribution to the science of dendrochronology,...

The aim of this work is to characterize the structure of beech stands at the timberline in the central Apennines (Gran Sasso and Monti della Laga National Park), and to analyze seed production and germination. Stand structure was analyzed using structural indexes with data collected in plots drawn...

Studies carried out on the southern Apennine mountains have evidenced that silver fir (Abies alba Mill.), a species of great ecological interest, is undergoing a sharp contraction in its spatial distribution. This contraction is mainly due to the considerable anthropic pressure exerted in the past, ...

Eight papers given at this conference are presented, which mainly concentrate on the use of dendrochronology, in northern Italy, to reconstruct climatic fluctuations, to investigate forest ecological history, or to date architectural or monumental woodwork.

A review of the history of dendrochronology and the construction of chronologies, and the applications of dendrochronology to historical and archaeological studies, art history, the study of musical instruments, dendroclimatology, forensic science and radiocarbon dating.

Few xylochronological studies have been carried out on linden trees. The particular anatomic structure of the wood and its radial growth characteristics sometimes lead to the formation of rings that cannot readily be identified. In this project, the classic techniques of dendrochronology were used...

The author gives a short overview of the uses of dendrochronology, citing some research examples in Italy, and describing how local dendrochronological data (wood growth ring widths) can be incorporated into larger regional curves.

This note describes the wood growth of two Turkey oak stands belonging to stored coppices with standards in Central Italy. In Mediterranean hilly stored coppices, even on fertile volcanic soils, stand productivity is controlled by climate variability, above all water availability. The climatic...

Tree ring growth of 10 tree species during 2002-04 was investigated in Italy. The species most affected by the drought of 2003 were wild cherry [Prunus avium], oak [Quercus] and chestnut [Castanea sativa].

Studies were conducted in the fossil forest (comprising Taxodioxylon gypsaceum, which became extinct during the Pliocene, and had anatomical features similar to Sequoia sempervirens). The forest originated during a period when climatic conditions were warmer and more oceanic than at present.
