    Opis:
    Leptospirosis is a widespread although recently neglected zoonosis recognized worldwide. The disease seems to be underestimated, especially in countries located in the temperate climatic zone. The presented article concerns the main characteristics of leptospirosis and describes formerly known and recently observed environmental, occupational and recreational risk factors significant in the spreading and pathogenesis of the disease. The aspects of epidemiology significant in the temperate climatic zone are emphasized. The majority of cited articles present cases of the disease reported from Europe or North America. Climatic changes (warming) and extreme weather events such as floods are potential risk factors of leptospirosis. Also, some socio-economic phenomena, such as the intensive migration of people resulting in the transfer of the infections acquired in tropical countries, or worsening of economic status in the cities, increase the probability of disease. Apart from the danger connected with rodents, which are the main vectors of leptospires, occurrence of the disease in dogs and cats can generate a higher risk of infection for humans. Infections may also be acquired during various types of agricultural work and during recreational activities, such as swimming. The results of recent investigations show that ticks are also potential vectors of leptospires. The more frequent emergence of leptospirosis in countries located in the temperate climatic zone emphasize the need to verify knowledge related to the risk of its appearance, and to consider this disease during diagnostic processes.

    Opis:
    The increase of Lyme borreliosis (LB) can be expected due to climate change, while the distribution of the disease and annual activity of the vector and host animals depend on several factors of the environment. The presented study aimed to assess expressly the spring season temperature dependence on the incidence of LB in Hungary. The weekly LB data were obtained from the National Epidemiologic and Surveillance System for a period of 13 years – 1998–2010. Daily temperature data were derived from the European Climate Assessment and Dataset. The association was studied at national level, descriptive statistics and linear regression models were applied. A significant increasing trend was observed in the mean temperature of the analysed years (0.052 °C per year). The annual LB incidence doubled during the 13 year period. The incidence rates of the periods 1998–2001 and 2007–2010 were 11.1 resp. 17.0 per 100,000. The start of a steep increase in weekly LB incidence (0.1 per 100,000) shifted significantly by 3 weeks earlier, the start date of spring showed similar trend (p=0.0041). LB incidence increased more steadily in spring than in summer, with 79% of the increase being reported during weeks 15–28, with maximum rates of increase occurring in weeks 23–25. The trend was significant between the weeks 15–28. In the warmer years with 19.02 °C mean temperature in May and June, the LB incidence curve reached the annual peak 2–3 weeks earlier, and the descending phase of the curve started earlier than in the colder years with 17.06 °C of the same period.

    Opis:
    Effects of the climate change appear in several fields of the economy and agriculture can be considered as one of the most affected among them. In a country, where almost 10% of the total GDP is produced by the agricultural sector and more than 30% of the total work force is employed in this field, these changes may have severe economic impacts. As in Romania almost 65% of the agricultural production is represented by vegetal production, we concentrate our investigations on this agricultural sector. Our aim is to present, basing on econometric modeling, how the climate changes will affect the Romanian crop production in the next 20 years, highlighting the territorial differences which appear between the Romanian NUTS2 development regions. This paper presents some of the first results of the FP6 research project “CLAVIER – Climate Change and Variability: Impact on Central and Eastern Europe”, contract no. 037013 (2006-2009).

    Opis:
    Forests are one the main natural factors that regulate and determine climate, weather patterns and amount of CO2 of an area. With rapid industrialization and rapid urbanization there is a significant increase in deforestation and as a consequence rise in global mean surface temperatures. Rapid and unchecked cut down of forest cover has resulted in some of the worst disasters during the last decades. This paper focuses on studying the role of deforestation, its influence on climate change phenomena and its consequences in Pakistan.

    Opis:
    W pracy zbadano wpływ czynników pogodowych na plonowanie odmiany Mirela łubinu wąskolistnego w latach 1990-2008 oraz dokonano prognozy plonów na lata 2050-2060, z wykorzystaniem modeli pogoda-plon, przy założeniu trzech scenariuszy zmian klimatu przeznaczonych dla Europy Środkowej: GISS model E, HadCM3 i GFDL. Materiał źródłowy stanowiły wyniki doświadczeń odmianowych oraz obserwacje meteorologiczne pochodzące ze stacji doświadczalnych COBORU, zlokalizowanych w północno-wschodniej Polsce. W analizach zastosowano metodę korelacji i regresji wielokrotnej krokowej postępującej. Dopasowanie modeli oceniono na podstawie współczynnika determinacji R², poprawionego współczynnika determinacji R² adj, błędu standardowego estymacji oraz współczynnika determinacji R² pred wyznaczonego przy użyciu procedury Cross Validation. Istotność równań regresji określono za pomocą testu F-Snedecora. Jedno z równań posłużyło do prognozy plonowania łubinu w warunkach podwojenia zawartości CO2 w atmosferze. Stwierdzono, że wpływ czynników meteorologicznych na plonowanie łubinu wąskolistnego był zróżnicowany w zależności od lokalizacji stacji. Na wysokość plonu najczęściej istotnie wpływała temperatura (maksymalna, średnia i minimalna) początkowych okresów wegetacji oraz opady w okresie koniec kwitnienia–dojrzałość techniczna. Badania wykazały, że przewidywane zmiany klimatu wpłyną korzystnie na plonowanie łubinu. Plony symulowane były wyższe od uzyskiwanych w latach 1990-2008, a najbardziej korzystny okazał się scenariusz HadCM3.
    The study examined the impact of weather factors on yielding of blue lupine cultivar Mirela in 1990-2008 and forecasted the yields for 2050-2060 using the weather-yield models and three climate change scenarios for Central Europe: GISS model E, HadCM3 and GFDL. The source material was the results of cultivar experiments and meteorological observations obtained from the COBORU research stations, situated in North-Eastern Poland. The analyses included the correlation and multiple progressive stepwise regression methods. The fitting of the models was evaluated with the coefficient of determination R², adjusted coefficient of determination R² adj, standard estimation error and coefficient of determination R² pred calculated with the Cross Validation procedure. The significance of regression equations was determined by a F-Snedecor test. The selected equation was used to prediction the yielding of lupin in conditions of doubling CO2 content in the atmosphere. It was found that the impact of meteorological factors on the yielding of blue lupine was diversified depending on the location of the station. Most frequently, the yield was significantly influenced by temperature (maximum, average, minimum) in the beginning of growing seasons and also by precipitation in the period: the end of flowering – technical maturity. The studies demonstrated that the predicted climatic changes would exert a beneficial impact on lupin yielding. Simulated yields were higher than those observed in 1990-2008 and the most favourable scenario was HadCM3.

    Opis:
    In the last few decades, changes of reproductive pattern of polar vascular plants have been observed, for the benefit of generative propagation. The reasons for this phenomenon are attributed to intensively following climate change, whose effects may be various. Warming causes the production of the greater number of generative structures, with higher quality. Our macroscopic observations conducted on specimens of polar vascular plants, cultivated in University of Warmia and Mazury greenhouse, indicate that the effect of temperature increase on flower development and seed formation is inconsistent. On the other hand enhanced levels of UV-B radiation can negatively affect seedlings. The complexity of the climate change causes tremendous difficulties in defining a clear and unquestioned way of modifications during the reproductive phase of the described plants.
