  1. 31. Mapping higher-order dynamics and interactions in complex networks

    Författare :Anton Holmgren; Martin Rosvall; Ludvig Lizana; Ingo Scholtes; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; networks; community detection; information theory; the map equation;

    Sammanfattning : Complex systems research seeks to explain emergent properties in social, technological, and biological systems that result from interactions between their components. As data on the intricate relationships within these systems become increasingly available, there is a growing need for more sophisticated models to describe them accurately and offer deeper insights.

  3. 32. Microbial Ecology of Granular Sludge

    Författare :Raquel Liebana; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-throughput DNA analysis; sequencing batch reactors; granular structure; wash-out dynamics; aerobic granular sludge; disturbance; fluorescence in-situ hybridization; microbial community dynamics; granulation; reproducibility;

    Sammanfattning : Granular sludge is an efficient and compact biofilm process for wastewater treatment. Despite the well-established methods for granule cultivation, the ecological processes underpinning the microbial community assembly during granulation are poorly understood. LÄS MER

  4. 33. Patterns of fish larvae and zooplankton distribution in mangrove-seagrass seascapes of East Africa

    Författare :Barnabas Alphonce Tarimo; Martin Gullström; Monika Winder; Mats Björk; Gunilla Rosenqvist; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fish larvae; zooplankton; population dynamics; community structure; environmental variables; seasonal variation; habitat use; mangroves; seagrass meadows; seascape connectivity; Tanzania; western Indian Ocean; marin ekologi; Marine Ecology;

    Sammanfattning : Mangroves and seagrass meadows create coastal seascapes acting as breeding and nursery grounds for many fish species in tropical areas. Despite increased awareness on the role of these coastal habitats to fish, less knowledge is given to fish larvae distribution and population dynamics, limiting the understanding of major drivers of fish population dynamics and fisheries resources management, particularly in understudied regions such as the Western Indian Ocean.

  5. 34. Cascading extinctions in food webs : local and regional processes

    Författare :Anna Eklöf; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cascading extinctions; complexity; connectance; dispersal; food web; local dynamics; regional dynamics; resistance; spatial structure; species loss;

    Sammanfattning : Ecological communities all over the world are loosing biodiversity due to different kinds of human activities and there is an urgent need of understanding how those losses affect the function of the ecosystems on which we all depend. The community's response to species losses is likely to depend on both the structure of the local community as well as its interactions with surrounding communities. LÄS MER

  7. 35. Modeling human gut microbiota: from steady states to dynamic systems

    Författare :Hao Luo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dynamics.; metabolic modeling; genome-scale metabolic model; gut microbiota; cybernetic model;

    Sammanfattning : Human gut microbes are an essential part of human sub-microscopic systems and involved in many critical biological processes such as Type 2 diabetes (T2D) and osteoporosis. However, the underlying mechanisms are unclear. LÄS MER
