  2. 1. Food selection and fitness optimisation in insects

    Author : Helene Bracht Jörgensen; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; food preference; nested PCR; fungal DNA; växtparasitologi; plant parasitology; Entomology; Entomologi; fungi; seeds; ground beetles; collembolans;

    Abstract : To optimise fitness is a continuous process which assists species survival in changing environments. Choosing an optimal diet is an essential part of the optimisation process and a key element of optimal foraging theory. READ MORE

  4. 2. The Spider and the Sea : Effects of marine subsidies on the role of spiders in terrestrial food webs

    Author : Kajsa Mellbrand; Peter Hambäck; Lena Kautsky; David Wise; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marine subsidies; food webs; stable isotopes; shore ecosystems; predators; spiders; Pardosa; algae; emerging insects; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Plant Ecology; växtekologi;

    Abstract : The purpose of this study was to identify if terrestrial arthropod predators on Baltic Sea shores vary in their use of marine versus terrestrial food items, and to construct a bottom-up food web for Baltic Sea shores. The inflow of marine nutrients in the area consists mainly of marine algal detritus and emerging aquatic insects (e.g. READ MORE

  5. 3. Characterisation of PFASs and Organofluorine in Freshwater Environments : Transfer from water to land via emergent aquatic insects

    Author : Alina Koch; Thanh Wang; Micael Jonsson; Leo W. Y. Yeung; Anna Kärrman; Lutz Ahrens; Jonathan Martin; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFASs; riparian zone; emergent aquatic insects; terrestrial consumers; stable isotopes; organofluorine mass balance; AFFF; point sources;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are anthropogenic contaminants of emerging concern, because many are highly persistent to degradation and have been linked to adverse effects in humans as well as their ubiquitous spread in aquatic environments. This thesis investigated distribution of PFASs and organofluorine in freshwater environments impacted by PFAS point sources. READ MORE

  6. 4. Searching for food in complex environments : Integrating processes at multiple spatial scales

    Author : Thomas Alexander Verschut; Peter Hambäck; Peter Anderson; Ring Cardé; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Associational effects; Natal experiences; Olfaction; Oviposition; Plant Ecology; växtekologi;

    Abstract : Resources are often unevenly distributed through the environment, resulting in a challenging task for insects to locate food, mates and oviposition sites. Consequently, there is an ongoing need to unravel how insects rely on behavioural and sensory traits while searching for resources in heterogeneous environments. READ MORE

  7. 5. On Textile Farming : Seeds as Material for Textile Design

    Author : Svenja Keune; Delia Dumitrescu; Högskolan i Borås; []
    Keywords : HUMANIORA; HUMANITIES; Textiles and Fashion Design ; Textil och mode konstnärlig ;

    Abstract : Presently, designing with living systems such as insects, fungi and bacteria has become an area of extended interest, proposing collaborative processes of designing and manufacturing - as a solution for symbiotic ways of living. On the scale of the interior, modern systems for interior gardening, combining both functional, e.g. READ MORE
