    Genetic variation in relation to substratum preferences of Hypogymnia physodes2009In: The Lichenologist, ISSN 0024-2829, E-ISSN 1096-1135, Vol. 41, p. 547-555Article in journal (Refereed)
    Abstract [en]

    Genetic variability and its relationship to substratum preferences within and among populations of the sorediate foliose lichen Hypogymnia physodes was investigated using sequence variation in the complete nrDNA internal transcribed spacer (ITS) region. A few samples of the putatively closely related, sorediate, H. tubulosa were also included. Samples were collected from each tree species in study sites in Estonia, Finland, and Sweden. In total, DNA sequences from 104 individuals of H. physodes and 16 of H. tubulosa were obtained. A group I intron situated at the end of the small subunit (SSU) of the nrDNA was detected in both species. Within-species variability was observed in both species: fifteen haplotypes were found for H. physodes and seven for H. tubulosa for the combined alignment of the intron and the ITS. Possible recombination within the total gene fragment was detected and hence the different regions (intron, ITS1, 5.8S, ITS2) were analysed separately. They show a different degree of variability both between each other and between the species. The number of haplotypes of H. physodes in the four regions are 5, 5, 1, and 5 and for H. tubulosa 5, 2, 1 and 2, respectively. A statistical parsimony estimation resulted in two unconnected networks; one containing all the samples of H. physodes and one containing all H. tubulosa samples. It was not possible to show different potentials of the different haplotypes for establishment on different substrata as the network of H. physodes indicates recombination within the ITS region which may be frequent enough to make this primarily clonally reproducing species to behave like a sexual species.

    Rapid changes in the epiphytic macrolichen flora on sites in southern Sweden2006In: The Lichenologist, ISSN 0024-2829, E-ISSN 1096-1135, Vol. 38, p. 323-329Article in journal (Refereed)
    Abstract [en]

    A relatively quick and simple method is presented for monitoring changes in distribution and in site and substratum preferences of epiphytic macrolichens; the method also records the natural turnover of common species. Changes in the epiphytic lichen flora in southern Sweden were recorded at 64 sites in 1986 and again in 2003. In total 1990 observations of lichens were recorded on 15 tree species, mainly on trunks but also on branches up to 2 in above the ground. Almost all species showed a high turnover with regard to substratum, including very abundant species such as Hypogymnia physodes. Many of the species had changed substratum within their sites, possibly reflecting a general change in the ecological quality of sites. Canonical Correspondence Analysis was used to extract the variation in species composition over time, using 1685 records of 55 lichen species on 8 different substrata. Some species such as Hypogymnia tubulosa had increased in abundance whilst others such as Vulpicida pinastri had decreased.

    Phylogenetic reconstruction of character development in Physciaceae2001In: The Lichenologist, ISSN 0024-2829, E-ISSN 1096-1135, Vol. 33, p. 3-23Article in journal (Refereed)
    Abstract [en]

    A cladistic analysis of the Physciaceae, based on morphological and chemical data, is presented. In the resulting phylogenetic reconstruction two major clades are formed, one containing the foliose genera (Anaptychia, Dirinaria, Heterodermia, Hyperphyscia, Physcia, Phaeophyscia, Physconia, Pyxine) and the fruticose Tornabea, and the other containing the remaining, mainly crustose genera. Rinodina appears as paraphyletic with representatives both at the base of the tree, at the same level as the mio major clads and at the base of the crustose clade. Also Mobergia has a basal position. The characters used and their distribution in the phylogenetic trees are discussed as well as their significance for the identification of monophyletic groups. The history of the family is also briefly hinted at and characters of importance for the recognition of new genera are surveyed. Relevant publications and the variation in secondary chemistry are presented in tables.
