2. 1. Autolytinae: molecules, morphology, and reproduction

   University dissertation from University of Gothenburg

   Author : Arne Nygren; Göteborgs universitet.; University of Gothenburg.; [2003]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Phylogeny; systematics; revision; new taxa; PhyloCode; reconstruction of ancestral states.;

   Abstract : Autolytines constitute a well delineated group of syllid polychaetes, separated from other syllids by the presence of a sinuous pharynx, lack of ventral cirri and reproduction with dimorphic sexes. The group comprises c. 170 nominal species distributed worldwide, mostly inhabiting hard substrates restricted to the continental shelf. READ MORE

   Abstract : The extracellular matrix is (ECM) is a network of large, structural proteins and polysaccharides, important for cellular behavior, tissue development and maintenance. Present thesis describes work exploring ECM as scaffolds for tissue engineering by manipulating cells cultured in vitro or by influencing ECM expression in vivo. READ MORE

6. 4. Fungal taxonomy and systematics in the digital era, with an outlook on the cantharelloid clade (Basidiomycota)

   University dissertation from University of Gothenburg

   Author : R. Henrik Nilsson; Göteborgs universitet.; University of Gothenburg.; [2007]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIKVETENSKAP; TECHNOLOGY; Cantharelloid clade; ectomycorrhiza; Agaricomycetes; phyloinformatics; barcoding;

   Abstract : Fungi form a large and ubiquitous group of organisms where species identification and delimitation on morphological grounds often fall short. DNA sequences have proved an invaluable information source for these pursuits and are now routinely used in most mycological laboratories. READ MORE

7. 5. Morphometric and molecular variation in the Nordic dogroses (Rosa Sect. Caninae, Rosaceae)

   University dissertation from Dep. Systematic botany, Ö. vallgatan 14-20, 223 61 Lund, Sweden

   Author : Åsa Olsson; Lunds universitet.; Lund University.; [1999]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; morphology; phytogeography; taxonomy; RAPDs; Morphology; Systematic botany; Geographic differentiation; Genetic diversity; chemotaxonomy. Physiology of nonvascular plants; Systematisk botanik; taxonomi; morfologi; kemotaxonomi. Växters fysiologi inte kärlväxter .;

   Abstract : In the present thesis, I investigate the hierarchical structure of morphometric and molecular diversity within and between the Nordic dogroses (Rosa Sect. Caninae, Rosaceae). I also investigate patterns of geographic differentiation and taxonomic relationships within the group. READ MORE
