The aim of this investigation is to present the results obtained during the survey of Lithuanian consumers in order to identify their attitudes towards food with genetically modified organisms (GMO). Investigating the consumers approach to genetically modified (GM) food, the following were considered: consumers’ opinions on GMO were analyzed, their knowledge about the presence of food containing GMO on the Lithuanian market, the mandatory GM food labelling, the behavior to a transgenic product while shopping, as well as consumers’ willingness to purchase such products. Data were gathered through a survey of 1000 Lithuanian residents. The empirical results indicated that the majority of the respondents’ attitudes towards food containing GMO are negative. The older consumers with less income are more against GM food compared to younger, wealthier households. 72% of consumers know that if the food contains GMO it must be indicated on the label. However, many consumers who oppose GMO do not try to avoid paying attention to the components of the product listed on its label. Only about a quarter of consumers while buying a product look for such information. This indicates that consumers are not really interested in whether or not the product contains GMO.
From 1 May of 2004, when Lithuania becomes member of the EU, the opportunity for Lithuania to benefit from European Union structural assistance became realistic in 2004–2006 Single Programming Document (SPD)and the Cohesion Fund Strategy for 2004–2006. The whole of this period, support for the SPD and Cohesion Fund projects was 5.9 billion Litas. Lithuania was also receiving assistance under the Transition Facility. The latter is to continue the Lithuanian institution-building and help address gaps in the administrative capacity to implement Community legislation and enforce it. 2007–2013, EU structural assistance Lithuania shall be granted by the European Social Fund, European Regional Development Fund and the Cohesion Fund under the 2007–2013 EU structural assistance in the recovery strategy (more than 23 billion Litas). The aim of article is analyze the implementation of EU assistance for Lithuania 2007–2013 years
Life tables for two populations of the common dormouse Muscardinus avellanarius (Linnaeus, 1758) are presented. The mortality rates qx of the common dormouse appeared to be relatively constant and did not follow a typically mammalian "U" shaped curve with age. Mortality rates increased evenly with age both in females and males, in both populations, whereas a decrease in qx was observed only among males in their third year of life. Specific characteristics of the qx curve for the common dormouse include the relative longevity of this small rodent, and rather constant mortality during hibernation in all years of life.

Effect of fertilizer on soil reaction

75%
The aim of study was to determine the influence of growing fertilizer rates on soil reaction. Soil samples were taken from experimental plots, where different amounts of NPK fertilizers were applied for perennial grasses within 6 years (1986 - 1992). The experimental design was 12 treatments in 4 replications, and established in sod-gleysolic loamy sand. Potential acidification of soil as a result of fertilization was calculated based on CaCO₃ balance and obtained results validated with the analytical tests of topsoil (0 - 20 cm) and subsoil (20 - 40 cm) reaction before and after experiment. Obtained results showed low performance of data obtained by calculation CaCO₃ balance, thereby using only CaCO₃ balance, it is risky to forecast soil acidification. In spite ofthat the used fertilizer rates changed in the widely ranges between treatments (N₀P₀K₀ - N₃₀₀P₁₂₀K₂₄₀), fertilization had not significant influence on soil reaction.
The occurrence of ergot [Claviceps purpurea (Fr.) Tul.] was studied in eight Lithuania-grown winter rye varieties at Šiauliai University’s Botanical Garden during the years 2002–2004. The source of infection consisted of ergot sclerotia incorporated in superficial layer of the soil between experimental plots of rye. Germination of ergot sclerotia and formation of ascocarps were assessed every three days from the first emergence of ascocarps over the soil surface. Percentage of flowering ears of rye was recorded every three days from the beginning of flowering of the first ears to the end of flowering. Percentage of ergot-infected ears and number of sclerotia per 1 m2 were estimated at rye hard maturity stage (BBCH 87). Averaged data from three experimental years suggest that local winter rye tetraploid variety Rûkai, characterised by late and lengthy flowering, exhibited the highest ergot susceptibility. Diploid varieties Duoniai and Joniai, flowering at a similar period as Rûkai, but having less expressed peak of flowering, were significantly less ergot – infected in 2002 and 2004, but in 2003 the occurrence of ergot on all the three varieties was similar. In our tests we did not reveal any increased ergot-susceptibility of the hybrid variety Esprit, although many authors indicate that hybrid varieties are the most susceptible to this pathogen. From the tested rye varieties, Walet, Motto and Hacada were found to be the least infected varieties, whose flowering was short and only a small number of ears flowered simultaneously. A strong negative correlation between crop density and ergot infection was established.
The results of two field experiments carried out on acid (pHKCl 4.2 - 4.3) sandy loam Dystric Podzoluvisol showed that the crops sensitive to soil acidity (winter wheat, fodder beets, spring barley and mixture of clover-timothy) were more productive on limed and fertilized soil. Crops less sensitive to acidity (winter ryes, potatoes, oats and mixture of lupine-oats) have the advantage on the acid and nonfertilized soil. The all-nutrient fertilizer application (NPK) increased the yield of crops sensitive to soil acidity on limed soil by 23.1 % and that of crops less sensitive to acidity by 18.0% in comparison to the yield of crops grown in acid soil. Therefore we can grow the crops less sensitive to acidity on the acid soil using optimum rates of cattle manure. The application of recommended rates of mineral fertilizers by growing crops sensitive to acidity on limed soil is more useful. The reaction of soil solution on liming soil must be higher than 5.5 pHKCl.
The distribution of heavy metals in sediments of the Nemunas river have been investigated. The most obvious anthropogenic impact has been observed in the middle part of the river. Nevertheless, sediment metal concentrations are within the limits of global, regional and local concentration levels. Particular attention has been paid to the Kaunas Reservoir. Although it is a part of the river, sediment characteristics, including metal distribution, have been found to follow the bottom dynamic zones, as in lakes. Metal concentrations in the Kaunas Reservoir are close to the concentrations in the upstream part of the Nemunas river, without indicating increased contamination with metals due to the lower flow velocity. An unusual Fe/Mn ratio is characteristic to the Reservoir. Fe concentrations confirm the occurrence of an­oxic hypolimnion, whereas Mn concentrations indicate the possibility of Mn transport from the nearshore sediments to the deepest places.
Recent results of field studies on the exposed coast of Lithuania were used to model the area occupied by the red alga Furcellaria lumbricalis using the Natural Neighbor interpolation technique, while linear regression was applied to estimate the species’ standing stock. The area covered by F. lumbricalis extended for 26 km along the coast between depths of 1 and 15 m. The maximum species cover in the study area ranged between 4 and 10 m depth, which is one of the widest in the Baltic Sea. The modelled area of F. lumbricalis covered 35 ± 11 km2 with a total biomass of 7554 ± 3813 t.
