  2. 11. Fruit and microbial cues in the behavioural ecology and management of Drosophila suzukii

    Author : Guillermo Rehermann Del Rio; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Investigating the factors that determine the behaviour of new pests is essential for understanding, predicting and managing their impact on natural and agricultural ecosystems. The spotted wing drosophila (SWD), Drosophila suzukii (Matsumura; Diptera: Drosophilidae), is a worldwide spreading polyphagous pest of soft fruit and berries. READ MORE

  4. 12. Movement patterns and displacement of a soil insect

    Author : Elna Nilsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; attraction; repellence; fatty acid; Ecology; Ekologi; alarm; autoregressive model; autocorrelation; random walk; Protaphorura armata; Collembola; migration; dispersal; movement; displacement;

    Abstract : Movement and dispersal are important determinants of the spatial distribution and persistence of animal populations in a heterogeneous environment. I studied the small-scale movement pattern of a soil-living insect, Protaphorura armata (Collembola) by using a video-equipment. READ MORE

  5. 13. Creating cell microenvironments in vitro

    Author : Patric Wallin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell migration; lipid bilayers; cell differentiation; liquid handling; surface functionalization; Microfluidics; chemotractant gradients; mammalian cell culture; cell microenvironments; in vitro screening assay;

    Abstract : Stem cells have a great potential to bring about advancements in fields like developmental biology, drug discovery, cancer biology and tissue engineering. In order to be able to use stem cells to their full potential, it is important to have control over their behavior. READ MORE

  6. 14. Zonal organization of the mouse olfactory systems

    Author : Fredrik Gussing; Staffan Bohm; Anna Berghard; Diego Restrepo; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; olfactory; vomeronasal; gene expression; zone; organization; behavior; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Animals survey their environment for relevant odorous chemical compounds by means of the olfactory system. This system is in most vertebrates divided into a main and accessory olfactory system with two specialized neuroepithelia, the olfactory and the vomeronasal epithelium, respectively. READ MORE
