Aim: Grass-yellow butterflies (Eurema) are a group of pantropical Pieridae distributed throughout Asia, Australasia, Africa and the New World. However, little is known about their diversification, including the biogeographic mechanism(s) explaining their circumglobal distribution. We present the first densely sampled, time-calibrated phylogeny and biogeographic reconstruction of grass-yellows to c
The joint actions of animals in partnerships or social groups evolve under both natural selection from the wider environment and social selection imposed by other members of the pair or group. We used experimental evolution to investigate how jointly expressed actions evolve upon exposure to a new environmental challenge. Our work focused on the evolution of carrion nest preparation by pairs of bu
Background: Under inflammatory conditions, T cell-dependent (TD) protein antigens induce proinflammatory T-and B-cell responses. In contrast, tolerance induction by TD antigens without costimulation triggers the development of regulatory T cells. Under both conditions, IgG antibodies are generated, but whether they have different immunoregulatory functions remains elusive. Objective: It was shown
This research uses data from observations of 8277 motorcyclists at various types of roads of the road hierarchy in Malaysia in 2015, to investigate the effects of road characteristics, motorcyclists’ riding behaviour, motorcyclists’ and motorcycles’ characteristics on the occurrence of riding with excessive speed. For data collection and analysis, new software, i.e. MECHROM, was developed.

Popular Abstract in Swedish Dagens samhälle är allt mer beroende av elektroniska hjälpmedel så som smarta telefoner, läsplattor, datorer osv. Prestandakraven ökar i en allt högre takt och därför måste även den bakomliggande teknologin följa samma trend. De flesta av oss vill att den nya mobiltelefonen ska ha så hög kameraupplösning som möjligt men få av oss tänker på att detta medför en större mä

Background and Purpose-We have previously shown that delivery of brain-derived neurotrophic factor (BDNF) through direct intrahippocampal gene transduction with a viral vector suppresses the formation of new dentate granule cells triggered by global forebrain ischemia. Here, we investigated whether inhibition of endogenous BDNF alters ischemia-induced neurogenesis in the dentate gyrus. Methods-Rat
The present thesis investigated Swedish nouns differing in concreteness, specificity and emotional content using linguistic, psycholinguistic and neurolinguistic methods. The focus of Paper I was a semantic analysis of discourse produced by a person with a lesion in visual (left occipital) cortex. The results showed that the lesion site was related to with problems processing concrete nouns relateThe present thesis investigated Swedish nouns differing in concreteness, specificity and emotional content using linguistic, psycholinguistic and neurolinguistic methods.

The material in Swedish herbaria previously identified as Hieracium sublividum (Dahlst.) Johanss. was revised using both the traditional taxonomical approach and PCA analysis based on 44 morphological characters. Only about half of the specimens did belong to H. sublividum s. stricto (known from the provinces Småland, Öland and Östergötland). Three new species were revealed and are described anew
While foreign direct investments (FDI) are promoted as a vehicle for economic development their environmental consequences are less established. This study tests the hypotheses that 1) FDI led to environmental degradation in form of increased greenhouse gas emissions during Sub-Saharan Africa´s recent growth spurt but that 2) this impact was felt to a lesser extent in countries with a higher quali

Accurate detection of SARS-CoV-2 neutralizing antibody (nAb) is critical for assessing the immunity levels after virus infection or vaccination. As fast, cost-effective alternatives to viral infection-based assays, competitive binding (CB) assays were developed to quantitate nAb by monitoring the ability of sera to inhibit the binding of viral spike (S) protein to the angiotensin converting enzyme
