Many of Sweden’s red listed species are found in the agricultural landscape. Small biotopes (e.g. field margins and field islets) are important for the maintenance of biodiversity in agricultural landscapes, and agri-environmental support is paid to farmers who keep them open. However, a proper evaluation of the biodiversity-gains from this type of management is lacking. We examined the predicted
An important constraint on the reliability of cosmogenic nuclide exposure dating is the rigorous determination of production rates. We present a new dataset for Be-10 production rate calibration from Mount Billingen, southern Sweden, the site of the final drainage of the Baltic Ice Lake, an event dated to 11,620 +/- 100 cal yr BP. Five samples of flood-scoured bedrock surfaces (58.5 degrees N, 13.
Comparison between growth variability, based on ring-width (RW) analysis, and moisture-sensitive signals in tree-ring carbon and oxygen stable-isotope composition provides increased understanding of how climate and hydrology influenced bog pines (Pinus sylvestris L) at two sites in southern Sweden during the mid- and late Holocene. Tree-ring sequences from two subfossil trees collected at raised b
Previous research findings suggest that our decisions are affected by the language they are made in. A recent study however indicates that this phenomenon might be related to an unexpected switch of language prior to a decision rather than to the use of a foreign language as such. To investigate this phenomenon further, the decision preferences of 200 participants, fluent in Swedish and English, w
Emotional Strain - Social Workers Experience of their Psychosocial Working There has been a rise in work-related mental health issues that leave people sick and absent from work. This is especially true for people in social work and in municipal social services with exercise of public authority. The employer has the legal responsibility for a healthy work environment, yet the responsibility for t
Using the three dimensions of the KOF index of globalization and average years of schooling the thesis examines openness as an effect on the extent of education. Econometrics is used to estimate regressions with panel data covering more than 100 countries. The results suggest that the impact of openness on education differs between high and lower income countries. Quite interestingly, the economic
Aim To assess statistically the relative importance of climate and human impact on forest composition in the late Holocene. Location Estonia, boreonemoral Europe. Methods Data on forest composition (10 most abundant tree and shrub taxa) for the late Holocene (5100-50 calibrated years before 1950) were derived from 18 pollen records and then transformed into land-cover estimates using the REVEALS v
A detailed stratigraphical, palaeoecological and geomorphological reconstruction of a fjord head on South Georgia (Husvik, Stromness Bay) is presented. Six sites were chosen to reconstruct the lithostratigraphy of the area by means of coring. A maximum depth of 11m was attained and the sediments encountered vary from coarse gravel over sands to fine silts with, in some cases, intercalated peat lay
Dispersal limitation and long-term persistence are known to delay plant species’ responses to habitat fragmentation, but it is still unclear to what extent landscape history may explain the distribution of dispersal traits in present-day plant communities. We used quantitative data on long-distance seed dispersal potential by wind and grazing cattle (epi- and endozoochory), and on persistence (adu
We report on a sediment record from a small lake within the subarctic wetland complex Stordalen in northernmost Sweden covering the last 1000 years. Variations in the content of minerogenic material are found to follow reconstructed variations in the activity of the Sun between the 13th and 18th centuries. Periods of low solar activity are associated with minima in minerogenic material and vice ve
Subantarctic islands are located within the Antarctic Circumpolar Current and the southern westerly wind belt, the latter called Southern Westerlies, making them unique terrestrial archives to investigate past changes in oceanic and atmospheric circulation patterns in the southern mid-latitudes. The islands are characterised by a treeless, phanerogam-poor flora in which bryophytes are of major imp
This study explores the relationship between land-use and floristic diversity between 600 BC and AD 2008 in the uplands of southern Sweden. We use fossil pollen assemblages and the Regional Estimates of Vegetation Abundance from Large Sites (REVEALS) model to quantitatively reconstruct land cover at a regional scale. Floristic richness and evenness are estimated using palynological richness and RE
Efforts to extract a Greenland ice core with a complete record of the Eemian interglacial (130,000 to 115,000 years ago) have until now been unsuccessful. The response of the Greenland ice sheet to the warmer-than-present climate of the Eemian has thus remained unclear. Here we present the new North Greenland Eemian Ice Drilling ('NEEM') ice core and show only a modest ice-sheet response to the st
1. Temperate semi-natural grasslands are characterized by high levels of species diversity and have a high conservation value. Plant species diversity in grazed semi-natural grasslands is known to be influenced by management intensity and habitat connectivity. Both grazing pressure and between-patch connectivity are expected to depend on the movement patterns of livestock in the landscape. 2. The
Measurements of Last Interglacial stable water isotopes in ice cores show that central Greenland delta O-18 increased by at least 3 parts per thousand compared to present day. Attempting to quantify the Greenland interglacial temperature change from these ice core measurements rests on our ability to interpret the stable water isotope content of Greenland snow. Current orbitally driven interglacia
In this paper we present new relative sea-level data from southern Greenland, a key area for understanding the Greenland Ice Sheet (GIS) response to climate change. Within fourteen lakes and marine lagoons from the inner part of Bredefjord (Nordre Sermilik) in southern Greenland, isolations revealed by stratigraphic and palaeoecological analyses are dated and relative sea levels reconstructed. Due
Background: During the past few decades Sweden has developed into a multicultural society. The proportion of patients with different cultural backgrounds increases, which naturally makes new demands on health care staff. Aim: To identify whether staff in somatic and psychiatric emergency care experienced problems in the care of migrants, and if so to compare these. Method: The study design was exp
