  1. 1. The spatial structure of genetic and morphometric variation in Corylus avellana (Betulaceae): pattern and scale

    University dissertation from Helena Persson, Department of Ecology, Systematic Botany, Sölvegatan 37, SE-223 62 Lund, Sweden

    Author : Helena Persson; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phytogeography; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .; taxonomy; morphology; Systematic botany; Öland; clonal structure; marginal and central populations; image analysis; aerial photographs; morphometric variation; allozymes; Corylus avellana; genetic variation;

    Abstract : In the present thesis, I investigated the spatial structure of genetic and morphometric variation in the widespread wind-pollinated shrub Corylus avellana (L.) Betulaceae, hazel, and related the variation to geographic distribution and different spatial scales. READ MORE

  2. 2. Genetic variation and population differentiation in the forest herb Lathyrus vernus (Fabaceae)

    University dissertation from Department of Ecology, Lund University

    Author : Katarina Schiemann; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .; taxonomy; morphology; phytogeography; inbreeding depression; Systematic botany; small population size; marginality; reproductive characters; leaflet shape; allozymes; Lathyrus vernus; genetic variation;

    Abstract : In the present thesis, I investigated patterns of genetic variation in the forest herb Lathyrus vernus (Fabaceae), using plant material from different-sized populations representing three geographically separated regions: central Europe, southern and central Sweden. My studies included presumably neutral or weakly selected characters (allozymes and leaflet shape) as well as characters that should be under strong directional selection (e. READ MORE

    Abstract : Genetic and morphometric variation was studies in the three closely-related taxa Silene vulgaris (a widespread weed), S. uniflora ssp. uniflora (restricted to coastal habitats) and S. uniflora ssp. READ MORE

  4. 4. Systematics of polyploid Dactylorhiza (Orchidaceae) - genetic diversity, phylogeography and evolution

    University dissertation from Helena Runyeon, Department of Systematic Botany, Östra Vallgatan 18-20, S-223 61 Lund, Sweden

    Author : Sofie Olofsson; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microsatellites; allozymes; ITS; plastid DNA; Dactylorhiza majalis ssp. traunsteineri; allopolyploidy; AFLPs; immigration history; diploidization; hybridization;

    Abstract : This thesis examines genetic variation in allotetraploids of the Dactylorhiza incarnata/maculata polyploid complex in different parts of Europe. The molecular markers used were AFLPs, allozymes, ITS, nuclear microsatellites and plastid DNA markers. READ MORE

  5. 5. Variation in Pseudorchis albida s.l. (Orchidaceae) and Carex capitata s.l. (Cyperaceae) : Morphology, genetic diversity, ecology and systematics

    Abstract : In the Scandinavian flora, several species-pairs where one member is an alpine species andthe other is a closely related lowland species, have been described. The aim of this studywas to investigate two such examples, viz. Pseudorchis albida s.s. READ MORE
