The Final motion of the Round table “The forest and man”, held in Florence in 1995, stated that “The forest is a complex biological system which has a fundamental role in maintaining life on our planet. Like all living systems, the forest has intrinsic value, it is a subject of rights which must be preserved and protected”. In the last decades a new forestry culture has developed which is based on three “E”s: Ecology, Economy and Ethics. Silviculture is a biological science and its vitality depends on its history and its ability to confront, not only on technical bases but also in scientific terms, the challenges coming from constant change. It is concluded that radical innovation is an asset of young people. They are the ones in charge of future scientific development. For this reason they must be educated to creativity and cultural independence. They must be aware of the importance of their work, which should be based on intense study and a search for excellence, even if this brings no immediate acknowledgement. If young researchers follow these rules, nothing will be precluded and success will finally arrive.</p><p><b>Keywords</b>: SISEF National Congress, Ecology, Economy, Ethics</p><p><i>Forest@ 0 (0): 45-46 ()</i> - doi: 10.3832/efor0087-012<br/><a href="" target="_blank"></a></p><hr size="1"/> Ciancio O Commenti & Prospettive 2015-10-24 Copyright (c) 2015, Italian Society of Silviculture an Forest Ecology.

The encyclical letter Laudato si’ of the Holy Father Francis on care for our common home, our planet, is considered. The approach to complex socioecological systems is stressed. In this same perspective, the tenth congress of the Italian Society of Silviculture and Forest Ecology, to be held in Firenze (Italy) next September 15th to 18th, aims to highlight the role of forests and forestry in supporting the life on the planet. Forestry can be one of the most dynamic sectors of the “green economy”. The ethical norm of respect for the intrinsic value of the ecosystem is just brought about by concern, closeness and familiarity between man and forest and, on the contrary, it may be hampered by aprioristic resource immobilization.</p><p><b>Keywords</b>: Encyclical Letter, Forestry, Land Ethic, Tenth Congress of The Italian Society of Silviculture and Forest Ecology</p><p><i>Forest@ 0 (0): 233-234 ()</i> - doi: 10.3832/efor0088-012<br/><a href="" target="_blank"></a></p><hr size="1"/> Corona P Editoriali 2015-08-25 Copyright (c) 2015, Italian Society of Silviculture an Forest Ecology.

Its range partly overlaps with that of European ash (Fraxinus excelsior) and interspecific cross is possible. These habitats are of the utmost importance due to their high level of biodiversity, but highly threatened by human activities. Since climate change is expected to favor the diffusion of narrow leaved ash, a study was carried out with the aim of enhancing our knowledge of the biological, ecological and genetic aspects of this species. Twelve populations of narrow leaved ash from north-eastern Italy were sampled and their genetic variability was analyzed by means of six molecular markers (nuclear microsatellites), of which 4 gave consistent and repeatable results. Overall, 113 alleles were observed, of which 38 were present in only one population (private alleles). Consistent levels of genetic variability was found (mean number of alleles per locus = 7.08, effective number of alleles per locus = 4.37, expected heterozygosity = 0.613), though lower than those reported in the literature. Fixation index was very close to zero, indicating a good agreement with Hardy-Weinberg’s expectations. The genetic differentiation among populations was significant (both GST e FST as high as 0.102), although it was not possible to correlate the distribution of genetic variability with ecological or geographical factors. Genetic pools of F. excelsior and F. angustifolia were distinct, though several individuals showed intermediate genetic characteristics, especially in the population from Grotta di Farra where both species are present and many individuals showed intermediate morphological features. The presence of individuals possibly originated by interspecific cross should be taken into account in the case of seed collection. Our results may contribute to a rationale management of genetic resources of narrow leaved ash, also considering the current legislation on forest reproductive material.</p><p><b>Keywords</b>: Narrow Leaved Ash, nSSR Markers, Genetic Variability, Genetic Differentiation, Interspecific Hybridization, Regions of Provenance, Seed Stands</p><p><i>Forest@ 0 (0): 217-232 ()</i> - doi: 10.3832/efor1628-012<br/><a href="" target="_blank"></a></p><hr size="1"/> Belletti P, Camerano P, Ferrazzini D, Fiorentin R, Cego Pernigotto F Articoli Scientifici 2015-08-08 Copyright (c) 2015, Italian Society of Silviculture an Forest Ecology.
