  1. 16. It's complicated: : The role of timing in microbial community coalescence

    Författare :Theresa Lumpi; Eva S. Lindström; Clara Ruiz-González; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; community coalescence; arrival timing; dispersal timing; microbial communities; community composition; lake bacteria; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Sammanfattning : In recent years, the importance of historical contingency has been increasingly recognized in microbial communities. During community coalescence, immigration history, and dispersal history can become decisive for the developing community. LÄS MER

  3. 17. Development and dynamics of the normal gut microbiota

    Författare :Lisa M. Olsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dynamics; ecology; gut microbiome; gut microbiota development; microbiota; richness; Prader-Willi Syndrome; stability; variation;

    Sammanfattning : Altered gut microbiota configurations have been linked to human diseases. To identify mechanistic links between altered gut microbiota and disease states, definitions of the healthy gut microbiota need to be established. LÄS MER

  4. 18. Species interactions govern evolutionary and ecological effects of population harvesting

    Författare :Anna Gårdmark; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; population harvesting; species interactions; ecological community; Ekologi; Ecology; competition; predation; fisheries; spatial dynamics; maturation; population dynamics; life-history evolution; adaptation;

    Sammanfattning : Harvesting changes population abundance and can affect adaptation of several life-history traits. Harvesting can also have indirect effects ? effects on non-target species and secondary effects on target species ? because interactions between species in a community determine the relevant ecological and evolutionary feedback environment.

  5. 19. Eco-evolutionary processes and community patterns--- novel avenues for studying biodiversity across spatial and temporal scales

    Författare :Yun-Ting Jang; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Eco-evolutionary dynamics; Community diversity patterns; Spatial phylogenetic patterns; Adaptive dynamics; Elevational diversity gradients; Theoretical ecology; Simulation models; Predation; Competition;

    Sammanfattning : Understanding biodiversity patterns poses a persistent challenge due to the complex interconnections of ecological and evolutionary processes. The particular difficulty comes from the various processes influencing biodiversity patterns across different spatial scales. LÄS MER

  7. 20. Drivers of Population Dynamics in Bacterioplankton : Spotlight on Alphaproteobacteria and its dominant SAR11 Lineage

    Författare :Friederike Heinrich; Stefan Bertilsson; Alexander Eiler; David Kirchman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bacterial community dynamics; Alphaproteobacteria; SAR11; LD12; Southern Ocean; lakes; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Sammanfattning : Bacteria are mediators of biogeochemical cycles and are in this way vital for maintaining life on earth. Their distribution, abundance and functioning are driven by environmental heterogeneity and dynamic change in abiotic and biotic factors. LÄS MER
