In this report, transgenic embryogenic tissue was obtained after the transformation of somatic embryos of Norway spruce (Picea abies (L.) Karst.) by Agrobacterium tumefaciens with the gus-intron chimeric gene. The stable integration of transgenes was confirmed by PCR and Southern hybridization. The transformation was successful only in a suitable embryogenic cell line sensitive to Agrobacterium. Out of the nine embryogenic lines tested only one gave transgenic callus.

Czech Republic Title: Reproductive and morphometric characteristics of wild boar (Sus scrofa) in the Czech Republic Abstract: Our study aimed to determine morphometric data for wild boar (Sus scrofa) in various areas of the Czech Republic and the potential influence of environment on its body measurements. Three localities with varying agricultural systems and overall landscape structure were selected. Hunted boars were measured for height at the withers, body length, ear length, metatarsal length and weight (depending on the circumstances, either dressed with head, without head, or undressed). We also determined the age of the hunted boars according to teeth development. During 2003-2007, a total 654 boars were examined in various age categories. Body development was similar in all areas and without statistically significant differences until the age of 6-7 months. From 8 months, statistically significant differences in body proportions occur across all localities. It is just at that time that carrying capacities change in the selected localities. The results show that morphometric differences among boars of the same age are influenced by external environmental conditions in which the boars live.

Data on precipitation from the period 1901-2005 and on temperatures from the period 1931-2005 were used. Statistically significant dependences with correlation coefficients in the range of 0.2-0.5 were confirmed. All tree species react positively to precipitation mainly in June and July. An increase in precipitation by 1 mm when compared with the long-term average results in an increase in increment index of spruce almost by 0.13%. This index in oak and beech increases only by a half value of the value for spruce. Precipitation from the second half of the vegetation period of the previous year is also important. Higher temperatures during the vegetation period affect increment changes mostly negatively. With temperature increase by 1°C, when compared with the long-term average, the increment index of trees decreases by about 1-2%.

At these sites, crop yield is generally low, and hence, conventional land use systems often fail in terms of reliable and efficient crop production. In this paper the attempt is made to evaluate the production of woody biomass for bioenergy in short rotation coppices (SRC) and alley cropping systems (ACS) with black locust (Robinia pseudoacacia L.) and lucerne (Medicago sativa L.) from the aspect of possible ecological and economic benefits compared to the conventional agricultural recultivation practice. The results show that, due to both high establishment and harvesting costs and comparatively low prices of energy wood, land use systems such as SRC or ACS are currently hardly profitable compared to conventional agriculture. However, the cultivation of black locust resulted in a higher humus accumulation and in a lower harvest-related nutrient export than the cultivation of lucerne as a typical recultivation crop in this region. Therefore, it can be concluded that for an improvement of soil fertility woody biomass production is more beneficial than the conventional agricultural recultivation practice.

Biotopes' gradual development was determined based on historical aerial photographs from 1949, 1974, 1988 and 2007. Issues evaluated include especially direct occupation of biotopes and agricultural lands due to constructing industrial areas in the motorway's vicinity, changes in area dimensions of agricultural and forest land, construction of residential complexes and complementary infrastructure. Also investigated was how these transformations and other negative factors of the linear construction, particularly barriers along the motorway and traffic intensity, influence migration of large ungulates. The aerial photographs show significant decrease in polygons in the Crop fields category between 1949 and 2007. While in 1988 the area of Commercial zones in this territory was only 0.16%, in 2007 these already constituted 8.53% of the entire territory. Forested area increased slightly. Traffic intensity and barriers along the motorway were found to create sections through which large mammals have great difficulty passing.
