Opis:: Shrubs are widespread at higher altitudes and latitudes. Dendrochronology of shrub growth has been intensively studied in the circumpolar Arctic, Mediterranean and Patagonia. However, relatively little is known about shrub growth responses to climate change on the Tibetan Plateau. Herein, we investigate climate sensitivity of Salix oritrepha growth along a north–south (35–39° N) latitudinal gradient on the north- eastern Tibetan Plateau. Four S. oritrepha shrub sites were selected for dendrochronology study. Pearson and partial correlation analyses were used to estimate strength of the climate sensitivity of the growth time series at each site. We found that not all of the site chronologies show consistent variations. Despite of this, its ra- dial growth was primarily limited by the July mean temperature across the latitudinal gradient, and warming summer climate tends to increase the growth of S. oritrepha on the northeastern Tibetan Plateau.

Opis:: Celem artykułu była ocena wrażliwości miasta Kalisza na czynniki klimatyczne jako podstawy opracowania miejskiej strategii adaptacyjnej. Ocenę oparto na danych i informacjach społecznych, gospodarczych i o środowisku – ilościowych i jakościowych. W analizach ustalono, że Kalisz najbardziej wrażliwy jest na fale upałów, powodzie i susze oraz koncentrację zanieczyszczeń powietrza. Grupy ludności najbardziej wrażliwe na fale upałów (dzieci i osoby starsze), stanowiące prawie 25% populacji miasta, w większości (prawie 72%), zamieszkują tereny śródmiejskie i osiedla blokowe, charakteryzujące się parametrami zagospodarowania terenu niekorzystnymi z punktu widzenia komfortu termicznego mieszkańców. W zasięgu wody 100-letniej mieszka ok. 1% ludności miasta, a wody 500-letniej ponad 4%. Powodzie zagrażają także części ujęć wody. Miasto jest podatne na podtopienia w wyniku opadów ulewnych oraz potencjalnie wrażliwe na susze. Ekspansja zainwestowania miejskiego na terenach otwartych po stronie nawietrznej oraz na terenach głównego kanału napowietrzania miasta w dolinie rzeki, spowoduje wzrost wrażliwości miasta na ten czynnik związany z klimatem. Uwzględnienie oczekiwanych zmian klimatu w dokumentach strategicznych rozwoju miasta w dłuższym horyzoncie czasowym powinno polegać na modernizacji sieci kanalizacyjnej, racjonalizacji zużycia wody, rozbudowie infrastruktury błękitno-zielonej, wprowadzaniu rozwiązań przyjaznych środowisku w ogrzewaniu i transporcie. W dziedzinie społecznej niezbędne jest zapewnienie klimatyzacji w okresie letnim w obiektach usług publicznych – ochrony zdrowia i edukacji.
The work aimed at assessing sensitivity to climate change of town of Kalisz to provide basis for urban adaptation strategy. The assessment was based on climatic, socio-economic and environmental data as well as on spatial management information. It was found that Kalisz are most sensitive to heat waves, floods, droughts and to air pollution. Groups of people most sensitive to heat waves (children and elderly people) which constitute almost 25% of the urban population, reside mainly in midtown areas and inhabit blocks of flats where thermal comfort parameters are disadvantageous for city dwellers. Nearly 1% of the town population lives within the reach of a 100-year flood water, while more than 4% live within the reach of a 500-year water. Floods also threat to a part of water intake installations. The town is prone to flush flooding which tend to occur here with increased frequency. The town depends on infiltrative intakes of quaternary water, it potentially makes Kalisz sensitive to droughts under condition of decreased precipitation and excessive exploitation of groundwater. The planned expansion of urban development onto windward open areas will block city ventilating channels what worsted air conditions in the city. Vital issues to be tackled include in urban strategies: upgrading of sewer system, water use rationalization, extension of blue-green infrastructure and introduction of environmentally friendly solutions in heat provision and city transportation systems.

Opis:: Nature reserves are one of the most important measures in saving biodiversity, however, during the climate change, a real danger arises, that these territories would not be able to fulfill the objectives. In order to mitigate negative effects of climate change in protected areas it is necessary to create and apply management programs, based on future ecosystems needs. The main aim of presented study was to evaluate sensitivity of rare and vulnerable species to climate change in order to suggest measures for better management of nature reserves in the future. According to scientific literature, 12 biological and ecological plant characteristics determining sensitivity of species (limiting factors) have been detected. 73 plant species that are protected in Lithuanian reserves were evaluated qualitatively according to limiting factors of climate change. As the result, it was offered to apply additional protection measures to 47 species in the light of climate change. Groups of plant species that should be affected highly negatively or highly positively were identified. 16% of plant species protected in nature reserves were evaluated as very sensitive to climate change and the condition of these plants may worsen. On the other hand, 14 plant species were given as least sensitive to negative effects and future climate is more favorable to species growth and spread than the existing. The highest danger is predicted for Silene chlorantha (Willd.) Ehrh., and the best condition is predicted for Mentha longifolia (L.) Huds. Dactylorhiza incarnata (L.) Soó. The study also gives recommendations for the protection of rare plants in the future. Different management measures are taken into account: mitigation of the direct effect of climate change (I), improvement of an existing level of rareness (II), respecting the relation to physical and biological environment (III), consideration of spread and geographical limits (IV). Three management intensity levels were suggested according to species sensitivity.

Opis:: ObjectivesA method of continuous heart rate (HR) and blood pressure (BP) recording was used for the evaluation of the cardiovascular system parameters in participants of short-term (<1 month) high-latitude expeditions, in comparison with the parameters of residents of Central Russia and the Arctic region.Material and MethodsA dynamic examination of participants of Arctic expeditions (30 men, residents of middle-latitude regions, aged 46.7±1.7 years), workers permanently living in Central Russia (the Moscow region, 44 men, aged 46.7±1.0 years) and residents of the North (the Murmansk region, 35 men, aged 46.6±1.3 years) was performed. The authors used a spiroartheriocardiorythmograph allowing the parallel recording of HR, BP, spectral characteristics of HR variability (HRV) and the variability of systolic BP (sBP) and diastolic BP (dBP), cardiac performance parameters, and spontaneous baroreflex sensitivity (BRS). The parameters were recorded at rest, in a sitting position, over 2 min.ResultsThe basic clinical parameters (HR, BP and cardiac performance) did not differ in the workers living in different climatic zones. However, the residents of the North demonstrated a lower total power (TP) of the dBP variability spectrum and a lower relative power of the high-frequency (HF) range in both the sBP and dBP variability spectra. The participants of expeditions to the North had a lower TP of the HRV spectrum (in comparison with both control groups) that did not change during the expeditions; BRS was reduced, while the TP of the sBP spectrum was increased in comparison with the corresponding parameters obtained from the residents of circumpolar regions, and decreased during the expedition in parallel with a decrease in the sBP values. The TP of both the sBP and dBP variability spectra, as well as the power of the HF range in these spectra, were similar in the participants of expeditions to those obtained from the residents of Central Russia, and they considerably surpassed the corresponding parameters in the northerners surveyed.ConclusionsThe revealed peculiarities of the cardiovascular system in the participants of high-latitude expeditions can be considered as correlates of positive, and adequate in terms of the physiological value, adaptive shifts in the autonomous regulation of the cardiovascular system.

Opis:: One of the conditions for effective water resources management in protected areas is local decision makers' knowledge about potential threats caused by climate changes. Our study, conducted in the uNeSCO Biosphere Reserve of t uchola Forest in poland, analyses the perception of threats by local stakeholders. their assessments of the sensitivity of four lakes to the extreme weather events are compared with hydrological studies. the survey shows that the lakes' varying responses to extreme weather conditions is rarely noticed by ordinary observers. their perception is usually far from the hydrological facts, which indicates a lack of relevant information or a failure in making it widely accessible and understandable. moreover, it is rather the human impact, not climate change, which is seen as the biggest threat to the lakes. Insufficient environmental knowledge may hinder the effective protection and management of natural resources, due to bad decisions and lack of the local communities' support for adaptation and mitigation policies.
