Sites at various distances from eutrophic and mesotrophic lakes and fens on the island Öland in southern Sweden were systematically surveyed in summer (May–August) and autumn (late September–October) to elucidate the hibernation sites of wetland carabid beetles. Thirty-five of 47 wetland species were found in their winter quarters. In areas ≤50 m from the lakes and fens, the observed as well as the ...

The Antarctic ecosystem represents a remote region far from point sources of pollution. Still, Antarctic marine predators, such as seabirds, are exposed to organohalogen contaminants (OHCs) which may induce adverse health effects. With increasing restrictions and regulations on OHCs, the levels and exposure are expected to decrease over time. We studied south polar skua (<i>Catharacta maccormicki</i>), ...

The aim of the paper is to explore the published management research on women entrepreneurs in Science, Technology, Engineering and Mathematics (also known as STEM) fields in order to offer a first, comprehensive state-of-the-art of this research. In doing so, a systematic literature review (SLR) of 32 papers has been undertaken. The results of this SLR show that the literature on this topic is still ...

<p><i>Purpose</i>: Government attention to women’s entrepreneurship has increased in the past two decades; however, there are few cross-cultural studies to inform policy development. This paper aims to draw on gender and institutional theory to report on the status of female-focused small and medium-sized enterprises/entrepreneurship policies and to ask how – and to what extent – do women’s ...

This paper focuses on women’s entrepreneurship policy as a core component of the entrepreneurial ecosystem. We use a systematic literature review (SLR) approach to critically explore the policy implications of women’s entrepreneurship research according to gender perspective: feminist empiricism, feminist standpoint theory, and post-structuralist feminist theory. Our research question asks whether ...

This study presents the first abundance estimate for the world's northernmost harbour seal (Phoca vitulina) population, which resides in Svalbard, Norway, based on three digital stereoscopic photographic surveys conducted in 2009 and 2010. The counts from these high resolution 3D images were combined with a novel method for estimating correction factors for animals that were in the water at the time ...

Lakes and wetlands, common ecosystems of the high northern latitudes, exchange large amounts of the climate-forcing gases methane (CH4) and carbon dioxide (CO2) with the atmosphere. The magnitudes of these fluxes and the processes driving them are still uncertain, particularly for subarctic and Arctic lakes where direct measurements of CH4 and CO2 emissions are often of low temporal resolution and ...

Empetrum nigrum is a plant common in northern ecosystems with capacity to produce allelopathic compounds, which among other effects inhibit seed establishment and germination of other plants. Some of the most studied compounds regarding this effect are batatasin-III and phenolic acids, among them caffeic acid, which account for a large proportion of the leaf’s biomass. 5 random sites were established ...

Svalbard fjords are facing a significant increase in Atlantic water inflow, which influences all ecosystem components, thus the objective of this study was to assess how recent Atlantification impacts the functioning of zooplankton community. For this purpose, two year-round operating sediment traps and associated hydrographic instruments, providing continuous time series of zooplankton and sediment ...
