  • Determinants of bryophyte species composition and diversity on the Great Alvar of oland, Sweden
  • 2018
  • In: Journal of Bryology. - : TAYLOR & FRANCIS LTD. - 0373-6687 .- 1743-2820. ; 40:1, s. 12-30
  • Journal article (peer-reviewed)abstract
    • Factors driving the species richness and distribution of bryophytes are poorly studied and not well understood, particularly in grasslands. We analysed the occurrence of bryophyte species and variation in species richness across 674 plots (0.5 m x 0.5 m) in alvar vegetation (grassland on limestone pavement with thin or no soil) on oland (Sweden) in relation to substrate characteristics and chemistry, inundation frequency, grazing pressure and geographical variables. We found 148 taxa, including 11 nationally red-listed ones. Species richness per plot was significantly associated with substrate type, positively associated with pH and grazing intensity, but negatively associated with soil depth. However, richness of species typical of, or restricted to, alvar habitats responded differently to richness of species more common in other habitats. Typical alvar species were favoured by high pH, shallow soil and low phosphate availability, while generalists preferred relatively low pH, higher phosphate availability and organic or mull soil types. Distance from the alvar margin had only weak effects. Concerning the effects on individual species and community composition, inundation frequency and pH were found to have the largest effects, although other factors (substrate type, soil depth, bare soil, bare stone, phosphate availability and grazing pressure) were more important for some individual species, stressing the importance of microsite variability and variability in management for regional species richness. From a conservation perspective, it is concluded that grazing is generally positive whilst factors increasing phosphate availability may disadvantage the typical alvar species, and proximity to the alvar margin is not a major problem.

  • Ten polymorphic microsatellite markers for Hieracium s.s. (Asteraceae)
  • 2010
  • In: Conservation Genetics Resources. - : Springer Science and Business Media LLC. - 1877-7260 .- 1877-7252. ; 2:1, s. 295-300
  • Journal article (peer-reviewed)abstract
    • Eight novel microsatellite markers were developed for Hieracium s.s. (excluding Pilosella) using a modified FIASCO protocol, and two out of nine microsatellites that were originally developed for Pilosella officinarum were optimised for Hieracium s.s.. All ten microsatellites consistently amplified loci from a wide range of representatives from north and central European species of various sections of the genus. When tested on 19 individuals, nine microsatellites were found to be highly polymorphic with 6–29 alleles, while one microsatellite marker was monomorphic. Cross-amplification showed that six of the ten microsatellites also amplified products in one taxon of Pilosella, P. floribunda × officinarum.
