    Sammanfattning : Environmental factors influence species and habitats on multiple scales creating a mosaic of distribution patterns. Studying factors shaping these patterns are central to our understanding of population dynamics and ultimately ecosystem functioning. LÄS MER

  2. 2. Climate Related Impacts on a Lake From Physics to Biology

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Thorsten Blenckner; Uppsala universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Ecosystem processes; climate; phytoplankton; NAO; SCI; ice cover; modeling; Biologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; limnologi; Limnology;

    Sammanfattning : Climatic variation and change affect the dynamics of organisms and ecosystem processes. This thesis examines phytoplankton as a target variable to trace climatic impacts on Lake Erken (Sweden) with special emphasis on the spring bloom. LÄS MER

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

    Detta är en avhandling från University of Gothenburg

    Författare :R. Henrik Nilsson; Göteborgs universitet.; University of Gothenburg.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mikrobiologi; Microbiology; Morfologi; Morphology; Systematik och fylogeni; Systematics and phylogenetics; Terrestisk ekologi; Terrestrial ecology; Bioinformatik; Bioinformatics; Bioinformatik; Bioinformatics; Cantharelloid clade; ectomycorrhiza; Agaricomycetes; phyloinformatics; barcoding;

    Sammanfattning : 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. LÄS MER

  4. 4. Effects of pharmaceuticals on natural microbial communities: Tolerance development, mixture toxicity and synergistic interactions

    Detta är en avhandling från University of Gothenburg

    Författare :Sara Brosché; Göteborgs universitet.; University of Gothenburg.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biologi; Biology; Terrestisk; limnisk och marin ekologi; Terrestrial; freshwater and marine ecology; antibiotics; pharmaceutical mixtures; microbial community ecotoxicology;

    Sammanfattning : Due to our extensive use of pharmaceuticals, low concentrations (picomol-nanomol/L) end up in the aquatic environment. Antibiotics comprise a group of pharmaceuticals specifically designed to disrupt microbial biochemical processes, and might therefore in particular have detrimental effects on microbial communities in the environment.

  5. 5. The importance of terrestrial carbon in plankton food webs

    Detta är en avhandling från Limnology, Department of Ecology, Lund University

    Författare :Cesar Bolivar Daniel; Lunds universitet.; Lund University.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lakes; Ecology; carbon; zooplankton; Spumella elongata; Poterioochromonas malhamensis; flagellates; bacteria; stable isotopes; photochemistry; autochthonous; DOC; allochthonous; plankton; Ekologi; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Sammanfattning : Allochthonous substances, i.e. produced in terrestrial ecosystems, are known to fuel bacterial production in humic lakes. I observed that allochthonous carbon subsidizes bacteria even at high levels of phytoplankton biomass. LÄS MER
