  1. 16. Factors influencing the biogeography of bacteria in fresh waters - a metacommunity approach

    Författare :Jürg Brendan Logue; Eva S. Lindström; Silke Langenheder; Lars Tranvik; Byron Crump; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacteria; diversity; richness; community composition; dispersal; metacommunity; fresh water; biogeography; Freshwater ecology; Limnisk ekologi; Microbiology; Mikrobiologi; Biologi med inriktning mot limnologi; Biology with specialization in Limnology;

    Sammanfattning : One of ecology’s primary goals is to comprehend biodiversity and its patterns of distribution over space and time. Since microorganisms play a pivotal role in key ecological processes, the diversity of microbial communities may have important implications for the stability and functioning of Earth’s ecosystems.

  3. 17. 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

  4. 18. The influence of trophic polymorphisms on habitat coupling in aquatic food webs

    Författare :Maria H. K. Marklund; Peter Eklöv; R. Svanbäck; Pierre Magnan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Sammanfattning : Trophic cascades, together with other indirect interactions are important aspects in shaping the composition and abundance of species in the food web. Theoretically, movement of energy between systems, and coupling between habitats by mobile predators have been suggested as being important for food web stability and evenness. LÄS MER

  5. 19. An exploration of freshwater microbial ecology : from streamlined genera to global networks

    Författare :Rhiannon Mondav; Stefan Bertilsson; Phyllis Lam; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microbiology; ecology; networks; streamlined; aquatic; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Sammanfattning : Microbes are the main drivers of biogeochemical cycles on Earth and even though freshwaters cover only a small area of terrestrial surfaces their contribution to global cycles is important. Global cycles are measured by exchanges between systems e.g. water to atmosphere or lithosphere and are mediated by microbial communities. LÄS MER

  7. 20. Dissolved organic matter in lakes : Chemical diversity and continuum of reactivity

    Författare :Alina Mostovaya; Lars Tranvik; Colin Stedmon; Uppsala universitet; []
    Nyckelord :dissolved organic matter; DOM; dissolved organic carbon; DOC; PARAFAC; reactivity continuum model; ultrahigh resolution mass spectrometry; FT-ICR-MS; organic matter characterization; decomposition kinetics; baseline metabolism; Biologi med inriktning mot limnologi; Biology with specialization in Limnology;

    Sammanfattning : Dissolved organic matter (DOM) is the largest pool of organic carbon in aquatic systems and an important component of the global carbon cycle. Large amounts of DOM are decomposed within lakes, resulting in fluxes of CO2 and CH4 to the atmosphere. LÄS MER
