  3. 27. Ecological niche dynamic, lessons from plankton

    Författare :Baptiste Serandour; Monika Winder; Thorsten Blenckner; Eric Goberville; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plankton; Metabarcoding; Spatial distribution modeling; Ecological niche; Climate Change; marinbiologi; Marine Biology;

    Sammanfattning : Abiotic conditions shape biological communities around the globe. Through spatial and temporal heterogeneity, environments impact plankton physiology, phenology and distribution. LÄS MER

  4. 28. Modelling soil temperature and carbon storage changes for Swedish boreal forests

    Författare :Magnus Svensson; KTH; []
    Nyckelord :SPAC; soil surface energy balance; Norway spruce; canopy; LAI; climate; nitrogen; CoupModel;

    Sammanfattning : With the use of a process-orientated ecosystem model andmeasurements conducted at different Swedish coniferous forestsites, abiotic and biotic interactions between tree and soilwere identified and related to governing factors. Two differentmodelling approaches to describe soil temperatures at two sitesincluding hydrological transects were tested (I). LÄS MER

  5. 29. Black mustard and the butterfly effect : metabolomics of plant-insect interactions under multiple stress conditions

    Författare :Stefano Papazian; Benedicte Albrectsen; Edward Farmer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plant physiology; metabolomics; glucosinolates; multiple stress; ozone; Brassica nigra; Pieris brassicae; Brevicoryne brassicae; biology; biologi; Environmental Science; miljövetenskap; molekylärbiologi; Molecular Biology; Entomology; entomologi;

    Sammanfattning : One main goal of ecological research is to understand nature´s complexity, in order to predict the potential impact of environmental perturbations. In this thesis, I investigate the ecological interactions between some of the most ancient organisms living on our planet: plants and insects. LÄS MER

  7. 30. Assessing and optimizing biofilter performance in drinking water treatment

    Författare :Nashita Moona; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-scale biofilters; sterilization.; optical properties; Biofilter; dissolved organic matter; treatment optimization; drinking water;

    Sammanfattning : Biological filtration is a widely used treatment barrier in drinking water treatment plants to ensure the biological stability of treated water in distribution systems. Biofilters remove particulate and dissolved organic matter (DOM) and biodegradable organic matter from water. LÄS MER
