  1. 21. Ecological and evolutionary assembly processes and metacommunity structure

    Författare :Mikael Pontarp; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Community; metacommunity; phylogenetic signal; ecology; evolution; assembly process; marine bacteria; habitat filtering; competition; mathematical modeling; simulation; eco-evolutionary;

    Sammanfattning : This thesis aims to elucidate the link between abiotic and biotic effects and biogeographical contingencies, eco-evolutionary assembly processes, and community structure in a spatially explicit metacommunity framework. To this end, we used structure analysis of naturally sampled and experimentally manipulated marine bacterial communities and mathematical eco-evolutionary modeling and simulations of metacommunity assembly.

  3. 22. Local institutions, biological conservation and management of ecosystem dynamics

    Författare :Johan Colding; Paul Cox; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systems Ecology; systemekologi;

    Sammanfattning : This thesis analyze local institutions and management practices related to natural resources and ecosystem dynamics, with an emphasis on "traditional ecological knowledge" systems. Papers I, II and III analyze ‘resource and habitat taboos’ (RHTs) with the objective to synthesize knowledge about informal institutions behind resource management. LÄS MER

  4. 23. Fragmented landscapes : Assessment and communication of landscape connectivity in human-dominated landscapes

    Författare :Arvid Bergsten; Örjan Bodin; Bo Ebenman; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fragmentation; Connectivity; Network; Spatial; Landscape; Dispersal; Planning; Social-Ecological; Scale; IIC; STS; naturresurshushållning; Natural Resources Management;

    Sammanfattning : This licentiate thesis summarizes the first half of my PhD on the theme of management of fragmented landscapes. The thesis applies – and reflects on the use of – network analysis of connectivity in relation to landscape planning. LÄS MER

  5. 24. A Journey towards Sustainable Small Wastewater Treatment Systems in Low and Lower–Middle Income Countries

    Författare :Claudia Cossio Grageda; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater treatment system; local stakeholders; operation and maintenance; sustainability assessment; institutional dimension; EVAS tool EVAluation of Sustainability ; low and lower-middle income countries; sustainability indicators; resource recovery; performance assessment;

    Sammanfattning : The sustainability of small wastewater treatment systems (WWTSs) in low and lower-middle income countries represents a challenge in terms of functionality and optimal performance in the ongoing effort to treat wastewater sufficiently to enable safe discharge or reuse. The reuse of wastewater is a common practice in these countries, especially where water resources are scarce. LÄS MER

  7. 25. Managing sea cucumber fisheries and aquaculture : Studies of social-ecological systems in the Western Indian Ocean

    Författare :Hampus Eriksson; Maricela de la Torre-Castro; Juan Carlos Castilla; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sea cucumbers; Bêche-de-mer; Trepang; Echinoderms; Fisheries; Aquaculture; Governance; Trade; Seafood; Tropical seascape; Zanzibar; Mayotte; Western Indian Ocean; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Collecting sea cucumbers to supply the high value Chinese dried seafood market is a livelihood activity available to many people in the Western Indian Ocean (WIO), making it an important part of local economies. These fisheries are generally not successfully managed and tropical sea cucumber fisheries show continuing signs of decline. LÄS MER
