    Metagenomic Analysis of the Indian Ocean Picocyanobacterial Community: Structure, Potential Function and Evolution.2016In: PLOS ONE, E-ISSN 1932-6203, Vol. 11, no 5Article in journal (Refereed)
    Abstract [en]

    Unicellular cyanobacteria are ubiquitous photoautotrophic microbes that contribute substantially to global primary production. Picocyanobacteria such as Synechococcus and Prochlorococcus depend on chlorophyll a-binding protein complexes to capture light energy. In addition, Synechococcus has accessory pigments organized into phycobilisomes, and Prochlorococcus contains chlorophyll b. Across a surface water transect spanning the sparsely studied tropical Indian Ocean, we examined Synechococcus and Prochlorococcus occurrence, taxonomy and habitat preference in an evolutionary context. Shotgun sequencing of size fractionated microbial communities from 0.1 μm to 20 μm and subsequent phylogenetic analysis indicated that cyanobacteria account for up to 15% of annotated reads, with the genera Prochlorococcus and Synechococcus comprising 90% of the cyanobacterial reads, even in the largest size fraction (3.0-20 mm). Phylogenetic analyses of cyanobacterial light-harvesting genes (chl-binding pcb/isiA, allophycocyanin (apcAB), phycocyanin (cpcAB) and phycoerythin (cpeAB)) mostly identified picocyanobacteria clades comprised of overlapping sequences obtained from Indian Ocean, Atlantic and/or Pacific Oceans samples. Habitat reconstructions coupled with phylogenetic analysis of the Indian Ocean samples suggested that large Synechococcus-like ancestors in coastal waters expanded their ecological niche towards open oligotrophic waters in the Indian Ocean through lineage diversification and associated streamlining of genomes (e.g. loss of phycobilisomes and acquisition of Chl b); resulting in contemporary small celled Prochlorococcus. Comparative metagenomic analysis with picocyanobacteria populations in other oceans suggests that this evolutionary scenario may be globally important.

    Resultat av laboratorieanalys av tre molekylära markörer för två kryptiska Hamatocaulis vernicosus-arter, för att bedöma dessas utbredning och förekomst i naturskyddade områden i södra Sverige2017Report (Other academic)
    Abstract [en]

    Based on three molecular markers, the nuclearITS and the plastid rpl16 and trnL-trnF,the Swedish geographical distributions of the two cryptic species of the moss Hamatocaulis vernicosus (Mitt.) Hedenäsare evaluated. New sequences for all three markers were generated for 47 SSwedish samples; for two additional samples, the sequence for one marker couldbe generated. The aim was to cover as many occurrences of the species inprotected areas in S Sweden as possible. The geographical distributions of thenew samples and an additional 42 Swedish ones from an earlier study show thatthe southern cryptic species reaches northwards to N Uppland and the LakeSiljan area in Dalarna, whereas the northern cryptic species occurs in most ofSweden. In both the cryptic species of H.vernicsosus, haplotypes (approx. = ‘genotypes’) that are frequent in Swedenare also well represented in protected areas; of the four haplotypes that werefound only once, one is from a protected area.

    Incisor enamel microstructure places New and Old World Eomyidae outside Geomorpha (Rodentia, Mammalia)2022In: Zoologica Scripta, ISSN 0300-3256, E-ISSN 1463-6409, Vol. 51, no 4, p. 381-400Article in journal (Refereed)
    Abstract [en]

    The lower incisor enamel microstructure of the fossil rodent family Eomyidae was believed to be three-layered and highly derived but rather uniform throughout the clade. Here, we describe a new four-layered schmelzmuster in Eomyidae consisting of a three-fold portio interna with longitudinal oriented, uniserial Hunter-Schreger bands and a one-fold portio externa, accounting for a unique enamel microstructure character combination in Rodentia. This new schmelzmuster type has developed early in eomyid evolution and is detectable already in the late Eocene (Chadronian) of North America. In European eomyids, it first occurs in the early Miocene (MN 3), implying that this four-layered schmelzmuster was not present in all members of the family but restricted to species included in Eomyini and some genera currently considered Eomyidae incertae sedis within Eomyidae. Additionally, our analysis recognizes three taxa with schmelzmuster divergent from all other eomyids. Incisor enamel microstructure does not advocate a close phylogenetic relationship of Eomyidae to either fossil or extant Heteromyidae and Geomyidae, nor to fossil Heliscomyidae and Florentiamyidae. Our results rather support the view that Eomyidae are placed outside Geomorpha.

    Conditions of emergence of the Sooty Bark Disease and aerobiology of Cryptostroma corticale in Europe2023In: NeoBiota, ISSN 1619-0033, E-ISSN 1314-2488, Vol. 84, p. 319-347Article in journal (Refereed)
    Abstract [en]

    The sooty bark disease (SBD) is an emerging disease affecting sycamore maple trees (Acer pseudoplatanus) in Europe. Cryptostroma corticale, the causal agent, putatively native to eastern North America, can be also pathogenic for humans causing pneumonitis. It was first detected in 1945 in Europe, with markedly increasing reports since 2000. Pathogen development appears to be linked to heat waves and drought episodes. Here, we analyse the conditions of the SBD emergence in Europe based on a three-decadal time-series data set. We also assess the suitability of aerobiological samples using a species-specific quantitative PCR assay to inform the epidemiology of C. corticale, through a regional study in France comparing two-year aerobiological and epidemiological data, and a continental study including 12 air samplers from six countries (Czechia, France, Italy, Portugal, Sweden and Switzerland).

    We found that an accumulated water deficit in spring and summer lower than -132 mm correlates with SBD outbreaks. Our results suggest that C. corticale is an efficient airborne pathogen which can disperse its conidia as far as 310 km from the site of the closest disease outbreak. Aerobiology of C. corticale followed the SBD distribution in Europe. Pathogen detection was high in countries within the host native area and with longer disease presence, such as France, Switzerland and Czech Republic, and sporadic in Italy, where the pathogen was reported just once. The pathogen was absent in samples from Portugal and Sweden, where the disease has not been reported yet. We conclude that aerobiological surveillance can inform the spatial distribution of the SBD, and contribute to early detection in pathogen-free countries.

    Co-exposure to highly allergenic airborne pollen and fungal spores in Europe2023In: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 905, p. 167285-167285, article id 167285Article in journal (Refereed)
    Abstract [en]

    The study is aimed at determining the potential spatiotemporal risk of the co-occurrence of airborne pollen and fungal spores high concentrations in different bio-climatic zones in Europe. Birch, grass, mugwort, ragweed, olive pollen and Alternaria and Cladosporium fungal spores were investigated at 16 sites in Europe, in 2005–2019. In Central and northern Europe, pollen and fungal spore seasons mainly overlap in June and July, while in South Europe, the highest pollen concentrations occur frequently outside of the spore seasons. In the coldest climate, no allergy thresholds were exceeded simultaneously by two spore or pollen taxa, while in the warmest climate most of the days with at least two pollen taxa exceeding threshold values were observed. The annual air temperature amplitude seems to be the main bioclimatic factor influencing the accumulation of days in which Alternaria and Cladosporium spores simultaneously exceed allergy thresholds. The phenomenon of co-occurrence of airborne allergen concentrations gets increasingly common in Europe and is proposed to be present on other continents, especially in temperate climate.

    Värdväxten Johannesört Hypericum spp.2022In: Yrfän, Vol. 3, p. 18-20Article in journal (Other (popular science, discussion, etc.))
    Abstract [sv]

    Johannesörter Hypericum spp. är ett släkte med sju arter i Sverige. De känns igen på de gula femtaliga blommorna med många ståndare. Fem av arterna är antingen sällsynta eller väldigt lokalt förekommande. Man syftar därför främst på de två vanliga arterna äkta johannesört H. perforatum och fyrkantig johannesört H.maculatum när man pratar om demsom värdväxter för insekter. Dessatvå arter förekommer i liknande biotoper, främst på torra till medelfuktiga gräsmarker och ruderatmarker. De kan förekomma i stor mängd på igenväxningsmarker. Fyrkantig johannesört finns generellt på lite fuktigare marker och längre norrut än äkta johannesört. Johannesörthar också kallats mannablod eftersom krossade blomknoppar ger enblodröd färg.

    A statistical model for predicting the inter-annual variability of birchpollen abundance in Northern and North-Eastern Europe2018In: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 615, p. 228-239Article in journal (Refereed)
    Abstract [en]

    The paper suggests amethodology for predicting next-year seasonal pollen index (SPI, a sumof daily-mean pollen concentrations)over large regions and demonstrates its performance for birch in Northern andNorth-Eastern Europe. Astatistical model is constructed using meteorological, geophysical and biological characteristics of the previous year).A cluster analysis of multi-annual data of European Aeroallergen Network (EAN) revealed several large regions inEurope, where the observed SPI exhibits similar patterns of the multi-annual variability.We built the model for thenorthern cluster of stations, which covers Finland, Sweden, Baltic States, part of Belarus, and, probably, Russia andNorway,where the lack of data did not allow for conclusive analysis. The constructed modelwas capable of predictingthe SPI with correlation coefficient reaching up to 0.9 for somestations, odds ratio is infinitely high for 50% of sites insidethe region and the fraction of prediction fallingwithin factor of 2 from observations, stays within 40–70%. In particular,model successfully reproduced both the bi-annual cycle of the SPI and years when this cycle breaks down.
