Land abandonment and secondary forest succession have played a significant role in land cover changes and forest cover increase in mountain areas in Europe over the past several decades. Land abandonm...
We examine the aspectual type of pictures, and how it interacts with temporal progression in pictorial narratives. Some examples suggest that pictures can have stative aspect and that such pictures ...
The objective of this study was to assess the use of peach pomace in total mixed ration (TMR) silages and clarify the differences in aerobic stability between TMR and TMR silages caused by lactic acid...
The knowledge of forest development after disturbances, particularly anthropogenic disturbances, is of major importance for forest management. Many areas of mountain forests in Europe have been affe...
Density of regeneration in European subalpine Norway spruce (Picea abies) forests is typically low with regeneration primarily located on dead or decaying wood. The post-disturbance development of t...
Open habitats in closed forests are formed by various biotic and abiotic factors. These new habitats differ from their former parent stands in light conditions and vegetation structure facilitating th...
The objective of this work is to characterize areas in a succession process (regrowth), in the Amazon region, using multitemporal analysis of TM acquired in 1985, 1988, 1992 and 1995 through digital ...
In the years 1999–2001 early stadiums of succession development of a floodplain forest were monitored in the wide bed of the Bečva River formed during the floods in 1997. Changing site conditions...

Secondary forests cover large areas of the tropics and play an important role in the global carbon cycle. During secondary forest succession, simultaneous changes occur among stand structural attribu...
In order to infer the climate and the floral changes during the early Cenozoic of central India, a critical analysis has been made of the generic composition of Deccan Intertrappean series of India, w...
Slovenia, like other developed countries, is characterized by the fact that the number of farm takeovers is decreasing and farms are not being transferred to successors in a timely manner. As an EU me...
