  2. 11. Genomic Diversity and Evolution of Parasitism in Nematode-trapping Fungi

    Author : Dag Ahrén; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; nematode-trapping fungi; expressed sequence tags; functional genomics; bioinformatics; parasitism; Genomic diversity; Evolution; Ekologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Nematode-trapping fungi are soil-living organisms that have the ability to form infection structures, traps to capture nematodes. Many nematode species are parasites on plants and animals, which have resulted in an interest to use the nematode-trapping fungi as biological control agents. READ MORE

  4. 12. Functional and Renewable Galactoglucomannan-based Hydrogels

    Author : Jens Voepel; Ann-Christine Albertsson; Ulrica Edlund; Gunnar Henriksson; Margaretha Söderqvist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polysaccharides; hydrogels; swelling; crosslinking; hemicellulose; release; polysackarider; hemicellulosa; hydrogel; läkemedelsfrisättning; förnyelsebar; tvärbindning.; Functional materials; Funktionella material;

    Abstract : Polysaccharides represent an important resource for a variety of products, from food via fuel supply to functional materials of every kind. Here they are, due to their natural diversity found in many special applications, e.g. in the biomedical sector. READ MORE

  5. 13. Diversity and Ecosystem Functioning : Redundancy and Resilience in Freshwater Bacterial Communities

    Author : Hannes Peter; Lars J. Tranvik; Eva S. Lindström; Silke Langenheder; Nelson G. Hairston; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biodiversity; ecosystem functioning; bacteria; fresh water; biofilms; multifunctionality; ecological networks; perturbation; fragility; Biologi med inriktning mot limnologi; Biology with specialization in Limnology;

    Abstract : Bacteria are immensely diverse and hold key-positions in essentially all biogeochemical cycles. In freshwater ecosystems, bacteria degrade and mineralize organic compounds, linking the pool of dissolved organic matter to higher trophic levels. READ MORE

  6. 14. Diversity, dynamics and deficits : the role of social networks for the health of aging populations in Indonesia

    Author : Julia Schröders; Miguel San Sebastian; Maria Nilsson; Fatwa Sari Tetra Dewi; Mark Nichter; Andreas Motel-Klingebiel; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; social networks; loneliness; aging; older adult health; noncommunicable diseases; disablement processes; healthcare utilization; elderly care; mixed-methods; causal inference; Indonesia;

    Abstract : Background: This thesis takes as a predicate that humans are social animals and as such, that their social networks and health are intrinsically connected. A guiding heuristic of this thesis was the Berkman model which conceptualizes how social networks impact health. READ MORE

  7. 15. Functional diversity of zooplankton in marine food webs : Integrating DNA metabarcoding and network modeling

    Author : Andreas Novotny; Monika Winder; Catherine Legrand; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plankton; Food-Webs; DNA metabarcoding; Marine; Baltic Sea; Marine Ecology; marin ekologi;

    Abstract : The oceans are important regulators of the Earth’s climate system by sequestering carbon from the atmosphere taken up by primary producers. Zooplankton, including protozoans and metazoans of different phyla and size classes, occupies several trophic niches and regulates energy flow between primary producers and fish. READ MORE
