Allozyme markers were used to fingerprint clones of the grassland plant Hieracium pilosella and, by inference, to estimate the relative importance of sexual and vegetative reproduction in a population. Field studies in populations of clonal plant species have often reported negligible or absent recruitment from seed. In contrast, studies of genetic markers have found substantial clonal diversity i
Argon clusters have been doped with krypton atoms in a pick-up setup and investigated by means of ultraviolet and x-ray photoelectron spectroscopy (UPS and XPS). The width of the krypton surface feature in the XPS spectra from mixed krypton/argon clusters has been studied and found to be narrower than in the case of homogeneous krypton clusters. By considering known spectral broadening mechanisms
The traditional notuion of democracy being anchored in discussions among citizens is highlighted. The chapter makes the claim that while civic talk is central to the life of democracy, there are many socio-cultural factors that impede poitical discussion. Also, while formal deliberation is important, even the free-flowing, messy and unpredictable converations of everyday life can give rise to the
An underwater ERT survey was made along a planned road tunnel for The Stockholm Bypass Project (Förbifart Stockholm). The aim was to assess the ability to identify variations in the depth of the bottom sediments, as well as variations in rock quality and the possible presence of weak zones in the rock. Reference data from a seismic survey and geotechnical drilling was used for evaluation the resul

This paper presents the cultural and archaeological context of the human fossil bones from Muierii Cave, dated by us to the age of 30 150 ± 800 14C years BP (Before Present) or 34 810 ± 927 cal years BP (calibrated years Before Present), and from Cioclovina Cave, dated to the age of 29 000 ± 700 14C years BP or 33 540 ± 832 cal years BP, in the Southern Carpathians. These are among the most ancien

Concerns are increasing about the loss of biodiversity under land use change and how this will affect the ecosystem services provided by natural and semi-natural communities and consequently how this will threaten human well-being. The thesis examines the impact of present and past land use on different aspects of biodiversity; namely species diversity, traits and functional diversity and on ecos
