The Turkey oak (Quercus cerris L.) is one of the least known species of trees of alien origin introduced to forests in Poland. Its natural geographical range embraces southern Europe and Asia Minor. It started to be grown on the Polish lands in 1813, planted primarily in parks and gardens, mostly in the western part of the country. On the basis of the present authors’ own field search, the literature, and unpublished data, it was possible to collect information about 22 places of occurrence of the Turkey oak in the woodland areas of Poland. A map of the distribution of this species is presented and the characteristics of its most extensive localities in forests are given. The oldest and most robust tree stands comprising Quercus cerris, planted in the fertile riverside habitats of the Oder river valley, have reached the age of 130-150 years. In those conditions the Turkey oak attains a height of 37 m and a breast-height diameter of up to 120 cm. Because of frequent frost damage and a low quality of trunks, it is of no productive significance in forestry. Even so, it is an interesting example of an alien oak species which, like the well-known  Q. rubra, shows the ability to expand in a woodland environment.

The study involved screening and SEM analysis of the micromorphological features of the abaxial leaf surface of ordinary epidermal cells, stomata and trichomes of two varieties of Quercus cerris L. The results indicated features distinguishing the two varieties: in var. austriaca the wax is present as crystalloids in the form of simple platelets, while in var. cerris the wax appears as a smooth layer. Moreover, the results point to some special characteristics of Q. cerris in relation to other Quercus species. The approximately square, not ellipsoid, shape of the peristomatal rims is typical of the species Q. cerris L.

The analysis was conducted on the wood of two 100−year−old oak species that grew in the riparian forest conditions. The aim of the study was to determine the effect of tree species on conventional wood densi− ty, compressive strength along the grain with a moisture content of 12% and above 30% and desorption strengthening. It was found that wood of both oak species differed in density, compressive strength along the grain and desorption strengthening. These differences should be taken into account in the processing and use of timber harvested in the prescribed cuts.

Oaks are classified heavily based on the leaf morphology. However, identification of specimens without acorns is usually controversial in Cerris section. Although members of Cerris section have a broad distribution area, there are only few taxonomic studies. Therefore, the current study is the first to show the discrimination of species in Cerris section based on leaf characters from Turkey. Discrimination among the members of Cerris section over Turkey (Q. cerris L. var. cerris, Q. ithaburensis Decne. subsp. macrolepis (Kotschy) Hedge and Yalt, Q. brantii Lindley, Q. libani Olivier, and Q. trojana P. B. subsp. trojana.) was aimed and variations within and among the species based on 15 qualitative leaf characters was presented. In this work we have studied the natural variability of these species by analysing leaf materials collected from 44 populations around Turkey. Cluster Analysis (CA) and Principal Component Analysis (PCA) were performed to assess intra-specific differentiation and to compare the distribution of variance in the individual and population level. The results showed that the leaf characters presented a good discrimination of five Cerris taxa in PCA at the population level, but the relationships between Q. ithaburensis subsp. macrolepis and Q. brantii showed complex groups in CA. Among the studied taxa, the highest variation was found within Q. cerris populations. In this work, we obtained discrimination of Cerris section species from Turkey based on leaf characters which is quite useful for those herbarium specimens without acorns and in other systematic observations.

Effects of wild boar grazing on the yield of summer truffle (Tuscany, Italy)

The research presented here seeks to describe the impact of wild boar to a natural truffle ground of Tuber aestivum Vittad. on Monte Amiata (Tuscany – Italy). Pedoclimatic analyses indicated that the selected area could be considered suitable for the truffle production. Then classification of the vegetation of a Quercus cerris forest was carried out exploring the possibility of the BACI (Before-After-Control-Impact) sampling design. Finally 10 plots were selected, half of which have been fenced. For the first time the impact of wild boar was evaluated by estimating the surface area turned over by its activity. Moreover in each plot the number and weight of summer truffles was performed every 10 days during the fruiting period (June-November 2006-2008). The hypothesis that the presence of Sus scrofa has a strong negative influence on truffle harvesting has been amply confirmed by the data presented here, given the large increase of fruiting bodies of the summer truffle collected in the fenced plots. Consequently the destructive behaviour of the wild boar imply not only an ecological but also an economic damage in areas in which non-wood forest products are an important source of income.
