Opis:
Day after day it is being demonstrated that Greece hides a buried treasure in its forests. The wild black truffles Tuber aestivum, T. uncinatum, T. brumale and T. melanosporum and the white truffle T. borchii and recently T. magnatum are picked in a variety of forest ecosystems all over the country. The information which has been collected has initiated a national programme on truffle cultivation which, so far, has immense appeal, especially among young farmers. The discovery of carpophores of T. magnatum, the most valued white truffle in the market, triggered the interest in studying the site characteristics, botanical and pedological, in order to help farmers to cultivate the species in similar sites. All carpophores were found under hornbeam (Carpinus orientalis) along the banks of a creek on alluvial sediment. Soil analyses of four soil samples from truffle nests showed a narrow range of values of pH in water (7.57–7.78) and 1N KCL (6.94–7.07) and a similar granulometric soil texture.

Opis:
From ancient to modern times, in the historical process of urban development, urban transportation has been developing along with the development of the city's political, economic and cultural industries, and the relationship between each other has always been a topic constantly discussed by planning scholars. The development of urban transportation promotes the urban population gathering and industrial development, and promotes the development of urban geographical space. At the same time, it also brings endless convenience to urban residents, so that they can complete the displacement from the beginning to the destination with relatively low cost. However, with the rapid development of urban scale and the rapid growth of urban population, the problems of traffic congestion and land resource shortage in big cities of China seriously restrict the improvement of the quality of life of residents and the further development of the city. In this context, compact city is the inevitable choice for future urban development, while the transportation system supporting compact city form can only be public transportation. As a high-volume, efficient and rapid public transport mode, rail transit can not only solve the traffic congestion problem in high-density areas of cities, but also optimize the development and utilization of urban land and adjust the urban spatial layout, which is of great significance for the sustainable development of cities. The network of rail transit in Beijing becomes the backbone of public passenger transport system, and play an irreplaceable role in guiding the urban space layout adjustment, population migration and the transformation of traffic structure. The study of travel characteristics of the residents who live along the rail transit, in-depth analysis the relationship of the rail transit, the population migration and commuter travel, it is of great significance providing decision support for urban planning. Based on binary choice model, establishing the residents' travel choice model, rail transit impact model of different crowds. Study the relationship between rail transit and residents' travel characteristics, predict the rail transit to guide the trend of population migration.

Opis:
The paper assesses the growth of nine seed stands of Picea abies (L.) Karst. of Istebna. The stands were selected on the basis of the dynamic height growth and good adaptation of their progeny under different site conditions. The d.b.h. increment of trees during the entire lifespan of stands is analysed in detail, especially its magnitude and dynamics during the last twenty years, i.e. from 1982 to 2001.

Opis:
Recently, Norway spruce stands in Beskid ¯ywiecki (Western Carpathians) have been plagued by bark beetle outbreak affecting an extensive area over a large range of altitudes. Georeferenced data (2356 records) from 2009–2011 of the volume of felled spruces showing insect infestation in forest sub-compartments were analysed with respect to selected site and stand characteristics. The infestation intensity varied between individual parts of the examined area. Spruce mortality, recorded evenly across all slope expositions, was higher in the zones 800 m – 1000 m and above 1000 m than in the zone below 800 m. The infestation intensity increased slightly with spruce representation in the stands and was higher in stands older than 80 years. There was no clear correlation between spruce mortality and site quality. However, in areas with more diverse and fertile sites mortality was lower. In overall, the results obtained in this study are in line with previous knowledge on the subject, but patterns describing bark beetle preferences in infested areas appear to be less pronounced than those found in earlier publications. Risk assessment and current planning of forest protection measures in stands affected by bark beetle outbreaks should be based on the here described characteristics of spruce susceptibility to insect infection.
