Spatiotemporal patterns of crop diversity reveal potential for diversification in Swedish agriculture

Increasing crop species diversity within a region could improve agricultural sustainability, but knowledge of the spatiotemporal variation of crop species diversity and how this is related to pedo-climatic conditions is limited. In the current study, we used historical crop data records to quantify how crop species diversity is related to pedo-climatic conditions, and how crop diversity developed over time at the national and regional scale in Sweden between 1965 and 2019. Crop diversity was quantified using the exponent of the Shannon index. We found spatial differences across the country, with a significant increase in crop diversity from the north to the south, showing that there is a strong natural control of latitude and associated mean annual temperature on crop diversity in Sweden. Mean annual precipitation and soil texture had no significant relationship with crop diversity across Sweden. At the national level, crop diversity had no significant change over time. At the county level, our analyses revealed different temporal trends between counties. Crop diversity increased over time in certain counties, while in others no change or a decrease occurred. The temporal changes could not be explained by climate trends, and were likely influenced by socioeconomic factors. However, more than half of the counties showed an increase in crop diversity, suggesting that it is possible to increase crop diversity in Sweden. Our study shows that both natural and socioeconomic factors need to be considered to achieve an increase in crop diversity in the future.

Diversity Barometer 2020: Attitudes towards Immigration and Ethnic Diversity in Sweden

Migration is topical in many counties, and attitudes towards immigration and ethnic diversity are volatile. In our longitudinal “Diversity Barometer”, we have studied changes in Swedes’ attitudes towards immigration and ethnic diversity in Sweden since 2005, using a postal questionnaire sent to a random sample of the Swedish population aged 18–75. In this article, we analyzed data from 2020 (n = 1035) in comparison with previous Diversity Barometer surveys from 2005 to 2018. The findings showed that Swedes had increased contact with immigrants from the Middle East, Asia and Africa. The majority had good experiences of studying or working with people with foreign background, although those with bad experiences had also increased. Attitudes towards immigration and ethnic diversity were more positive in 2020, thereby stopping a negative trend that started with the refugee influx in 2015. Positive attitudes were more established among women, younger people, those with higher education, people living in larger cities and those with more contact with people with foreign background. Sympathizers of political parties closer to the left wing were more positive towards immigration and ethnic diversity. We used political correctness, contact theory, strain theory and theory about group conflict/threats to provide hypothetical explanations for the observed changes in attitudes.

Changes Regarding Attitudes Towards Ethnic and Cultural Diversity in Sweden: The Diversity Barometer (2005-2018)

This article aims to discuss changes in attitudes towards immigrants in Sweden from 2015 onwards, based on the results of the longitudinal Diversity Barometer studies from 2005-2014, 2016 and 2018. The Diversity Barometer studies are based on a national, representative, and randomly selected sample from the Swedish population, with a new sample selected each time. We have analyzed the changes from a sociological perspective, using theories such as contact theory and group conflict theory. The results show an increase in negative attitudes towards ethic and cultural diversity generally, and towards immigrants specifically. Diversity in culture and religion – especially towards Islam – is more negatively perceived as compared to diversity in the work domain. Societal groups with extensive experience from contact with foreigners, those who identify themselves as women, those who are more educated, younger people and city dwellers, have all a more positive attitude towards diversity than others.

Functional Diversity of Riparian Woody Vegetation Is Less Affected by River Regulation in the Mediterranean Than Boreal Region.

River regulation may filter out riparian plants often resulting in reduced functional diversity, i.e., in the range of functions that organisms have in communities and ecosystems. There is, however, little empirical evidence about the magnitude of such reductions in different regions. We investigated the functional diversity patterns of riparian woody vegetation to streamflow regulation in boreal Sweden and Mediterranean Portugal using nine plant functional traits and field data from 109 sampling sites. We evaluated changes in mean plant functional traits as well as in indices of multidimensional functional traits, i.e., functional richness (FRic) and functional redundancy (FRed) within regions and between free-flowing and regulated river reaches. We found that regulation significantly reduced functional diversity in Sweden but not in Portugal. In Sweden, the increased magnitude of variations in water flow and water level in summer, the prolonged duration of extreme hydrological events, the increased frequency of high-water pulses, and the rate of change in water conditions were the likely main drivers of functional diversity change. Small riparian plant species with tiny leaves, poorly lignified stems, and shallow root systems were consistently associated with regulated sites in the boreal region. In Portugal, the similar functional diversity values for free-flowing and regulated rivers likely stem from the smaller streamflow alterations by regulation combined with the species legacy adaptations to the Mediterranean natural hydrological regimes. We conclude that streamflow regulation may reduce the functional diversity of riparian woody vegetation, but the magnitude of these effects will vary depending on the adaptations of the local flora and the patterns of streamflow disturbances. Our study provides insights into functional diversity patterns of riparian woody vegetation affected by regulation in contrasting biomes and encourages further studies of the functional diversity thresholds for maintaining ecosystems.

A5 Near full-length HIV-1 genome sequencing in newly diagnosed individuals in Sweden

The Swedish HIV-1 epidemic is characterized by a high diversity in HIV subtypes and recombinants as a result of migration. To study the time from infection through viral diversification, transmission patterns, and drug resistance in minor quasispecies, a robust protocol for pan-genotypic near full-length HIV-1 genome (HIV-NFLG) next-generation sequencing (NGS) is key. Our group has established two protocols for HIV-NFLG on the Illumina platform that we aim to compare and, if necessary, modify to find a method with optimized coverage, depth, and subtype inclusivity. Zanini et al. (https://doi.org/10.7554/eLife.11282.001) have developed a method with one-step RT-PCR with six overlapping primer sets, followed by NGS and quality filtering and assembly with in-house methods. Aralaguppe et al. (https://doi.org/10.1016/j.jviromet.2016.07.010) have designed amplification in two fragments, followed by multiplexed NGS and quality control and assembly with Iterative Virus Assembler and VICUNA. Both methods have high coverage per nucleotide and low error rates in amplification and sequencing and can reliably identify SNPs at 1 per cent of the viral population with linkage within the quasispecies. Subtype inclusivity remains a challenge even though both methods show success in amplifying and sequencing subtypes B, C, and the common recombinants 01_AE and 02_AG. Therefore, we aim to evaluate and optimize our NFLG NGS methods on a panel of patient samples that more completely reflects HIV-1 diversity in Sweden. Patient samples from fifty treatment-naïve viremic individuals representing the genotypic HIV-1 panorama in Sweden, including CRFs, are being amplified and sequenced by both protocols. Coverage of the genome, error rate, and possible depth of quasispecies analysis is being evaluated. We will compare number of reads, coverage across the HIV genome, and representation of minor single nucleotide variants as well as subtype inclusivity and impact of plasma RNA levels. To do this we will use an in-house bioinformatic pipeline. The NFLG sequences will also be analyzed with phylogenetic tools for determination of subtypes including CRFs and URFs.

Making Women in Jazz Visible: Negotiating Discourses of Unity and Diversity in Sweden and the US

The aim of this article is to examine responses to a project that aspires to further gender-equal jazz scenes in Sweden and the US. The project brought together actors at various levels of the industry: cultural agencies, commercial organizers, activists, and artists. Our analysis – with special focus on resistance voiced – is based on observations, interviews with organizers, and a documentary about the project. The project’s central ambition was to make women in jazz visible in order to change a structural imbalance where men still take up most of the space on stage. This ambition was, however, complicated as different actors resisted a female–male binary, and thus the very idea of “women in jazz”. The resistance was played out through gender equality discourses of either unity or diversity, varying in relation to national context and generation. The article also discusses visibility as a central but also problematic aspect for gender equality efforts in music

Comparative and transnational perspectives on the introduction of multiculturalism in post-war Sweden

In the 1970s, Canada, Sweden and Australia became the first countries in the West to adopt formally the idea of multiculturalism as a basis for the political management of immigrant settlement. This article compares the introduction of the idea and politics of multiculturalism in Sweden in the 1960s and 1970s to the introduction of multiculturalism in Canada and Australia during the same time period. The emergence of a politics of multiculturalism in Sweden shares many similarities with the emergence of Canadian and Australian multiculturalism: ‘white’ and ‘European’ immigrant minority groups; ethnic lobbying; expert and academic advocacy; multiculturalist public officials; and effectual claims-making based on the innovative idea of multiculturalism. The comparative perspective on the birth of Swedish multiculturalism furthermore highlights Finland as an important historical and transnational factor in the introduction of official multiculturalism in Sweden. The article contributes to research on the history of multiculturalism, the politics of ethnic diversity in Sweden and comparative research on modern Swedish history.

A limited number of ITS haplotypes defines the diversity of Pneumocystis jirovecii strains in Sweden

The infectious fungus Pneumocystis jirovecii remains an important cause of pneumonia (PCP) in the immunocompromised host. To study the biodiversity of P. jirovecii in Sweden the internal transcribed spacers (ITS) of the rDNA locus were amplified, cloned and sequenced from a set of diagnostic respiratory specimens obtained from 64 patients with P. jirovecii infection during the years 1996–2003. The analysis of 408 cloned sequences from amplified products resulted in the identification of 10 ITS1 and 12 ITS2 established genotypes. Twelve ITS haplotypes (combinations of ITS1 and ITS2) were identified of which nine were found to recur during the time span of the study. Haplotype Eg was the most common, followed by Ne, Bi and Eb. A new ITS2 genotype denoted v was identified in specimens from four patients. There was no association between ITS haplotype and patient age, sex, underlying disease or geographical origin. Shannon and Simpson index analysis revealed no difference in diversity in Sweden compared to other countries studied and no changes in diversity were found during the study period in Sweden. Criteria were defined to enable the discrimination of genuine ITS types and a more accurate assessment of the previously overestimated genetic diversity of P. jirovecii populations. A model depicting the phylogenetic and genealogic relationships in a revised set of global types of this fungus is presented.

Intercultural education in Sweden through the lenses of the national minorities and of religious education

The aim of this paper is to discuss two perspectives in relation to intercultural education and diversity in Sweden. One of the perspectives concerns the historical and current situation of the five Swedish national minorities with a special focus on education. The second perspective is related to religious diversity and education, as connected to an increasingly democratic, plural and inclusive society. Both perspectives are highly relevant when analysing intercultural education in a specific national context. The last section highlights two main discourses which have been predominant during the last century in relation to education and diversity in Sweden.

Student attitudes towards diversity in Sweden

The aim of the research reported in this paper was to study and analyse student attitudes towards ethnic diversity and their expectations regarding the school in creating positive attitudes. The results show that the majority of the students embrace a positive attitude towards multicultural society. However, this attitude varies when the variables of gender and tracking level are examined. Most students support a strong stand for taking an active approach against racism in school. There is an undertone of an appeal to teachers to remove flyers and other signs of discrimination and racism. Students with a negative or monocultural attitude need teachers who can act as active role models in creating a multicultural attitude. Den forskning som rapporteras i föreliggande artikel syftade till att studera och analysera elevers attityder till etniska relationer samt deras förväntningar på skolans roll med avseende på skapandet av positiva attityder. Resultatet visar att majoriteten av eleverna har en positiv inställning till det multikulturella samhället. Denna attityd varierar emellertid mellan olika grupper beroende på kön och studieinriktning. Majoriteten tar stark ställning för en aktiv hållning mot rasism från skolan. Det finns en underton av vädjan till lärarna att hjälpa till att få bort flygblad och andra tecken på diskriminering och rasism. Elever som har en negativ eller monokulturell attityd behöver lärare som kan vara aktiva förebilder för i skapandet av en multikulturell attityd.

Y-chromosome diversity in Sweden – A long-time perspective

Sixteen Y-chromosomal binary markers and nine Y-chromosome short tandem repeats were analyzed in a total of 383 unrelated males from seven different Swedish regions, one Finnish region and a Swedish Saami population in order to address questions about the origin and genetic structure of the present day population in Sweden. Haplogroup I1a* was found to be the most common haplogroup in Sweden and accounted, together with haplogroups R1b3, R1a1 and N3, for over 80% of the male lineages. Within Sweden, a minor stratification was found in which the northern region Västerbotten differed significantly (P < 0.05) from the other Swedish regions. A flow of N3 chromosomes into Västerbotten mainly from Saami and Finnish populations could be one explanation for this stratification. However, the demographic history of Västerbotten involving a significant male absence during the 17th Century may also have had a large impact. Immigration of young men from elsewhere to Värmland at the same time, can be responsible for a similar deviation with I1a* haplotypes. Y chromosomes within haplogroup R1b3 were found to have the highest STR variation among all haplogroups and could thus be considered to be one of the earliest major male lineages present in Sweden. Regional haplotype variation, within R1b3, also showed a difference between two regions in the south of Sweden. This can also be traced from historical time and is visible in archaeological material. Overall this Y chromosome study provides interesting information about the genetic patterns and demographic events in the Swedish population.
