  2. 1. Clonal structure and reproductive biology in the gynodioecious herb Glechoma hederacea L. Lamiaceae

    Author : Marie Widén; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systematisk botanik; chemotaxonomy. Physiology of nonvascular plants; phytogeography; morphology; taxonomy; Systematic botany; clonal structure; isoloci; disomic inheritance; genetic diversity; polyploidy; male sterility; sex expression; pollen limitation; sexual reproduction; gynodioecy; Glechoma hederacea; Lamiaceae; taxonomi; morfologi; kemotaxonomi.

    Abstract : Clonal structure and reproductive biology in the gynodioecious herb Glechoma hederacea L. Lamiaceae The frequencies of females, hermaphrodites and partially male-sterile (PMS) genets of Glechoma hederacea were estimated in natural populations in S Sweden. The frequency of females and PMS genets in natural populations varied from 0 to 100%. READ MORE

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

    Author : Helena Persson; Biologiska institutionen; []
    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

  5. 3. Haemophilus influenzae – typing, epidemiology and beta-lactam resistance

    Author : Viktor Månsson; Malmö Klinisk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; benzylpenicillin; beta-lactam resistance; beta-lactams; BLNAR; capsule typing; clonal; Haemophiilus influenzae; Hib; MALDI-TOF MS; MLST; NTHi; serotyping; virulence; epidemiology;

    Abstract : Haemophilus influenzae is a common cause of respiratory tract infections such as acute otitis media (AOM), exacerbations of chronic obstructive pulmonary disease (COPD) and pneumonia. The species is subdivided into encapsulated and non-encapsulated strains, designated type a-f and nontypeable H. influenzae (NTHi), respectively. READ MORE

  7. 5. Genetic Disequilibria and the Interpretation of Population Genetic Structure in Daphnia

    Author : Lars M. Berg; Xavier Vekemans; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; breeding system; linkage disequilibrium; dispersal; genetic structure; Daphnia pulex; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; naturvårdsbiologi; Conservation Biology;

    Abstract : Understanding the processes that shape the spatial distribution of genetic variation within species is central to the evolutionary study of diversification and demography. Neutral genetic variation reflects past demographic events as well as current demographic characteristics of populations, and the correct interpretation of genetic data requires that the relative impact of these forces can be identified.
