Journal article (peer-reviewed)abstract
- We compared land cover, riparian vegetation, and instream habitat characteristics with stream macroinvertebrate assemblages in 25 catchments in the Carpathian Mountains in Central Europe. This study area was particularly selected because of its diverse history of forest and agricultural ecosystems linked to geopolitical dynamic, which provide a suite of unique landscape scale, land cover settings in one ecoregion. Canonical Correspondence Analysis (CCA) showed that variation in composition and structure of macroinvertebrate assemblages was primarily related to four land cover types, and not to riparian or instream habitat. These were the portions in the catchment areas of (1) broadleaved forest, (2) fine-grained agricultural landscape mosaic with scattered trees (e. g., pre-industrial cultural landscape), (3) mixed forest, and (4) natural grassland without trees. Principal Component Analysis (PCA) suggested that land cover types and stream channel substrates co-varied. The PCA also showed that chemical variables, including organic carbon, had higher values in the agricultural landscape compared to natural forests. The major source of variation among taxa in streams was higher abundance of Diptera in agricultural landscapes and of Plecoptera, Coleoptera, Trichoptera, and Amphipoda in forests. Gastropoda and Oligochaeta were more abundant in open, fine-grained agricultural landscape mosaics with scattered trees. Ephemeroptera taxa were quite indifferent to these gradients in catchment land cover, but showed a tendency of being more abundant in the pre-industrial cultural landscape. Our findings suggest that land cover can be used as a proxy of the composition and structure of macroinvertebrate assemblages. This means that land use management at the catchment scale is needed for efficient conservation and recovery of stream invertebrate communities.

Scholars' open debate paper on the World Health Organization ICD-11 Gaming Disorder proposal
- 2017

Journal article (other academic/artistic)abstract
- Concerns about problematic gaming behaviors deserve our full attention. However, we claim that it is far from clear that these problems can or should be attributed to a new disorder. The empirical basis for a Gaming Disorder proposal, such as in the new ICD-11, suffers from fundamental issues. Our main concerns are the low quality of the research base, the fact that the current operationalization leans too heavily on substance use and gambling criteria, and the lack of consensus on symptomatology and assessment of problematic gaming. The act of formalizing this disorder, even as a proposal, has negative medical, scientific, public-health, societal, and human rights fallout that should be considered. Of particular concern are moral panics around the harm of video gaming. They might result in premature application of diagnosis in the medical community and the treatment of abundant false-positive cases, especially for children and adolescents. Second, research will be locked into a confirmatory approach, rather than an exploration of the boundaries of normal versus pathological. Third, the healthy majority of gamers will be affected negatively. We expect that the premature inclusion of Gaming Disorder as a diagnosis in ICD-11 will cause significant stigma to the millions of children who play video games as a part of a normal, healthy life. At this point, suggesting formal diagnoses and categories is premature: the ICD-11 proposal for Gaming Disorder should be removed to avoid a waste of public health resources as well as to avoid causing harm to healthy video gamers around the world.

Bannlys alla politiska beslut som ger mer klimatutsläpp
- 2014

In: Dagens Nyheter.

Journal article (other academic/artistic)abstract
- Torftig valdebatt. Dagspolitiken klarar inte att hantera ödesfrågan om klimatet, vilket oroar oss. Vi föreslår därför ett ”utsläppsmoratorium”: inga beslut får tas som ökar utsläppen av växthusgaser. Principen måste kopplas till mål om exempelvis förnybar energi och grön infrastruktur, skriver 23 forskare och debattörer.

Conceptualising public health : An introduction
- 2018
-
In: Conceptualising Public Health. - London : Routledge. - 9781138036833 - 9781351712873 ; , s. 1-17
-
Book chapter (peer-reviewed)abstract
- In the introduction to the volume Conceptualising Public Health: Historical and Contemporary Struggles over Key Concepts, Sophy Bergenheim, Johan Edman, Johannes Kananen and Merle Wessel provide a comprehensive guide to the book and its academic fields. The chapter clarifies the volume’s conceptual history approach and goal; the editors and contributors approach concepts and discourses related to public health, health policy and medicine from an analytical and constructivist perspective in order to reach their various historical and political layers. Furthermore, the reader is provided with a historical overview of international and Nordic public health history, in order to properly contextualise the book’s chapters. The introductory chapter also presents central literature and positions the volume in relevant academic fields, as well as presenting the anthology’s individual chapters and their contribution.

European wild boars and domestic pigs display different polymorphic patterns in the Toll-like receptor (TLR) 1, TLR2, and TLR6 genes

Journal article (peer-reviewed)abstract
- During the last decade, the Toll-like receptors (TLRs) have been extensively studied and their immense importance in innate immunity is now being unveiled. Here, we report pronounced differences – probably reflecting the domestication process and differences in selective pressure – between wild boars and domestic pigs regarding single nucleotide polymorphisms (SNPs) in TLR genes. The open reading frames of TLR1, TLR2, and TLR6 were sequenced in 25 wild boars, representing three populations, and in 15 unrelated domestic pigs of Hampshire, Landrace, and Large White origin. In total, 20, 27, and 26 SNPs were detected in TLR1, TLR2, and TLR6, respectively. In TLR1 and TLR2, the numbers of SNPs detected were significantly lower (P ≤ 0.05, P ≤ 0.01) in the wild boars than in the domestic pigs. In the wild boars, one major high frequency haplotype was found in all three genes, while the same pattern was exhibited only by TLR2 in the domestic pigs. The relative frequency of non-synonymous (dN) and synonymous (dS) SNPs was lower for the wild boars than for the domestic pigs in all three genes. In addition, differences in diversity between the genes were revealed: the mean heterozygosity at the polymorphic positions was markedly lower in TLR2 than in TLR1 and TLR6. Because of its localization – in proximity of the bound ligand – one of the non-synonymous SNPs detected in TLR6 may represent species-specific function on the protein level. Furthermore, the codon usage pattern in the genes studied deviated from the general codon usage pattern in Sus scrofa.

European wild boars and domestic pigs display different polymorphic patterns in the Toll-like receptor (TLR)1, TLR2, TLR6, and TLR10 genes.

Conference paper (other academic/artistic)abstract
- The Toll-like receptors (TLR) are vitally important pattern recognition receptors linking innate and adaptive immunity. Several single nucleotide polymorphisms (SNP) in human TLR genes have been associated with disease. There are few studies on associations between polymorphisms in TLR genes and disease in pigs, but the TLR2/TLR6 heterodimer is activated by Mycoplasma hyopneumoniae, and the expression of TLR2, TLR4, and TLR9 is modulated in the presence of different Salmonella serovars. Porcine TLR1, TLR6, and TLR10 are located in a cluster on the p arm of chromosome 8, while TLR2 resides on the q arm. Previously, we identified quantitative trait loci (QTL) for immune-related traits on pig chromosome 8, close to the KIT gene and the microsatellite S0225, respectively. In order to explore polymorphism in some TLR genes in European wild boars and domestic pigs, TLR1, TLR2, and TLR6 were sequenced in 25 wild boars, representing three populations, and in 15 domestic pigs of Hampshire, Landrace, and Large White origin. Similarly, TLR10 was sequenced in 15 wild boars and 15 domestic pigs. In TLR1 and TLR2, more SNP were present in the domestic pigs than in the wild boars. In TLR6, SNP numbers were similar in both animal groups, but the level of heterozygosity was higher in the domestic pigs than in the wild boars. In TLR10, again, more SNP were present in the domestic pigs, and a higher number of nonsynonymous SNP were detected in TLR10 compared to the other genes. This may suggest redundancy for TLR10 in pigs.
