Intraspecific variation can have important consequences for the structure and function of ecological communities, and serves to link community ecology to evolutionary processes. Differences between the sexes are an overwhelmingly common form of intraspecific variation, but its community-level consequences have never been experimentally investigated. Here, we manipulate the sex ratio of a sexually
In this thesis we study the width of the Higgs boson in the process pp → t ̄t 4l at LO using MadGraph5_aMC@NLO to generate the events. The contributions including the Higgs signal, continuum background and interference were considered in order to calculate the expected number of events in a broad range of four-lepton invariant masses. Due to strongly enhanced off-shell contributions an upper bound

During the last decade, the ecological theory of adaptive radiation, and its corollary "ecological speciation", has been a major research theme in evolutionary biology. Briefly, this theory states that speciation is mainly or largely the result of divergent selection, arising from niche differences between populations or incipient species. Reproductive isolation evolves either as a result of direc
We have previously demonstrated that the genes of SCPs (semen coagulum proteins) and the WFDC (whey acidic protein four-disulfide core)-type protease inhibitor elafin are homologous in spite of lacking similarity between their protein products. This led to the discovery of a locus on human chromosome 20, encompassing genes of the SCPs, SEMG1 (semenogelin I) and SEMG2, and 14 genes containing the s
In total, 33 and 65 chrome-spinel (Cr-spinel) grains in the >63 and 32–63 µm size fractions, respectively, were recovered from 12 beds in two stratigraphically separated groups along the 240-m-thick Monte Acuto section of the Maiolica limestone in central Italy, spanning from the Berriasian to the early Hauterivian. The chemistry of these detrital spinels suggests they may represent windblown ophi
The use of animal models in Parkinson's disease research has been controversial in terms of how well they relate to the clinical condition and thus their utility for translating therapies from the lab to the clinic. In this article, two researchers debate this issue with Roger Barker taking the view that such models are not useful and may even be misleading, while Anders Björklund defends their us
Are women absent from Western Music History? This is a question of an apparent and easy answer; however, the reality differs. This issue prevails and only started to be discussed more seriously in recent years, since feminism has been a current on-going discussion through the world. In music, circumstances are seemingly slower to evolve still allowing discriminative actions. Through the analysis o
The development of clean technology (cleantech) is necessary in order to address many prominent environmental challenges. However, financing can be a hurdle for the development of cleantech companies. Venture capital (VC) plays an important role in cleantech development. While the four large Nordic countries are regarded as performing well in terms of cleantech innovation there are signs that VC i
Official calls for “failed” asylum seekers to leave Sweden ignore the difficulties and harms befalling stateless people who cannot return to previous countries of residence because they lack citizenship. Stateless people are caught in limbo, a position where they have no prospects of return or of attaining a residence permit in a predictable future. To learn the underlying logics and consequences
