The Scanian Economic-Demographic Database (SEDD) at the Centre for Economic Demography (CED), Lund University was built to answer questions derived from previous research using macro data from 1749 onwards. It includes longitudinal micro data for a regional sample of rural, semi-urban, and urban parishes in southern Sweden from 1646 to 1968 for approximately 175,000 individuals. In addition to the data on births, deaths, marriages, and occupations, it includes data on migration, household size, landholdings, taxation, and heights from the 1800s onwards and on income from 1865 onwards. After being linked from 1968 to 2015 to a range of national registers with detailed demographic and socioeconomic information, it includes 825,000 individuals. The richness and wide range of micro data have allowed researchers to follow individuals throughout their lives and across generations, covering extensive periods, and to make comparisons with results from macro data. This research has partly confirmed the established view on long-term changes in living standards and demographics in Sweden but has also brought into question some previously held truths.

Precipitation And Temperature

Long-term changes in precipitation and temperature indirectly impact aquifers through groundwater recharge (GWR). Although estimates of future GWR are needed for water resource management, they are uncertain in cold and humid climates due to the wide range in possible future climatic conditions. This work aims to (1) simulate the impacts of climate change on regional GWR for a cold and humid climate and (2) identify precipitation and temperature changes leading to significant long-term changes in GWR. Spatially distributed GWR is simulated in a case study for the southern Province of Quebec (Canada, 36,000 km2) using a water budget model. Climate scenarios from global climate models indicate warming temperatures and wetter conditions (RCP4.5 and RCP8.5; 1951–2100). The results show that annual precipitation increases of >+150 mm/yr or winter precipitation increases of >+25 mm will lead to significantly higher GWR. GWR is expected to decrease if the precipitation changes are lower than these thresholds. Significant GWR changes are produced only when the temperature change exceeds +2 °C. Temperature changes of >+4.5 °C limit the GWR increase to +30 mm/yr. This work provides useful insights into the regional assessment of future GWR in cold and humid climates, thus helping in planning decisions as climate change unfolds. The results are expected to be comparable to those in other regions with similar climates in post-glacial geological environments and future climate change conditions.

AbstractAn analysis of long-term changes in abundance of hibernating bats as revealed from the annual monitoring programme conducted in four mountain regions of the Western Carpathians (Muránska planina Mts, Revúcka vrchovina Mts, Slovenský kras Mts, Štiavnické vrchy Mts) during the period 1992–2009 is providing in the paper. Data from 52 hibernacula were analysed. Among 18 bat species recorded, an apparent population increase of three most abundant thermophilous and originally cave dwelling species of bats, Rhinolophus hipposideros, R. ferrumequinum, Myotis myotis, was observed. In other bat species (e.g., R. euryale, M. emarginatus, M. mystacinus, M. dasycneme, Barbastella barbastellus), population trends could not be detected and because of data scarcity, they should be evaluated from more extensive datasets obtained from a wide range of hibernacula or from a completely different type of evidence.

Problem Statement and Purpose. The Lower Dniester delta and the Dniester estuary are very important because they are natural filters of the river water from pollution and suspended matter, as well as they are the habitat of a large number species of flora and fauna. The construction of reservoirs on the Dniester River in past completely changed the hydrological regime of the river itself and of the Dniester estuary. For these reasons a constant environmental monitoring of the aquatic environment are required. Since 2002 Odessa I. I. Mechnikov National University has been carrying out a wide range of environmental studies in the Dniester estuary, one of aspects of which is observation of hydrological characteristics. The purpose of this paper is to study long-term changes in transparency, temperature and electrical conductivity of the Dniester estuary water in the summer periods of 2003–2019. Materials & Methods. Measurements of transparency, temperature and electrical conductivity of water in the Dniester estuary in the indicated years were carried out according to standard methods at 19 ecological stations. Statistical processing, analysis and mapping of the measurements results were conducted in EXCEL, ARCGIS, SURFER software’s. Data analysis was based on a graphical representation of the spatial distribution of characteristics, as well as by identifying the features of long-term changes in these characteristics. Main Results and Conclusions. On the basis of the summer surveys during 2003–2019 more than double decrease of water transparency mean values in the Dniester estuary has been established. It was found that the maximum transparency values were observed in the central parts of the estuary, far from settlements. For theseyears, an increase of the mean water temperature for the estuary northern part and its decrease in the middle and southern parts has been recorded. Also, for the summer period of these years, an increase of the mean water electrical conductivity in all parts of the estuary was established. The established features of spatial distribution of hydrological characteristics indicate to the river runoff, intrusion of seawater into the estuary, and wind activity as the determining factors in formation of the estuary hydrological regime. Recorded long-term trends of the means transparency values decreasing and the means temperature and electrical conductivity increasing of the Dniester estuary water in the summer of 2003–2019 are considered as consequences of the river discharge decreasing due to long-term climatic changes over Europe and man regulation of river flow.
