  2. 21. Predator effects on behaviour and life-history of prey

    Author : Tomas Brodin; Frank Johansson; Bradley Anholt; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; activity; behaviour; behavioural syndromes; damselfly; development; growth; life-history; predator-prey interaction; predation risk; thinning; Freshwater ecology; Limnisk ekologi;

    Abstract : In this thesis I investigate predator-induced effects on behavioural and life-history characteristics of prey. At any moment a given predator is capable of attacking a small number of prey. READ MORE

  5. 23. Stopover behaviour in migratory songbirds: timing, orientation and departures

    Author : Sissel Sjöberg; Funktionell zoologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; flight duration; orientation; departure timing; stopover behaviour; stopover duration; flight behaviour; reverse migration; route choice; compass calibration; passerines; Bird migration;

    Abstract : Songbird migrants use stopovers between flight bouts to rest and refuel for the upcoming flights. Behaviours affecting where, when and how long to stay at stopover sites will affect how successful the overall migration will be, which has significant consequences for the overall fitness and mortality of the birds.

  6. 24. Microstructure-based Mechanical Behaviour in Structural Analyses of Cast Components

    Author : Jakob Olofsson; Ingvar L. Svensson; Salem Seifeddine; Torsten Sjögren; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Component behaviour; Structural analysis; Mechanical behaviour; Casting process simulation; Finite element method simulation;

    Abstract : In the process of developing cast iron and cast aluminium components, the co-operation between product development and production is important. On the engineering level, this co-operation is limited already in the product development phase e.g. by the lack of established methods to consider the mechanical behaviour of the completed component.

  7. 25. Behaviour and metabolic rates of brown trout and Atlantic salmon : Influence of food, environment and social interactions

    Author : Linnea Lans; Larry Greenberg; Eva Bergman; Felicity Huntingford; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Salmo trutta; Salmo salar; behaviour; metabolic rates; Biology; Biologi;

    Abstract : For Atlantic salmon (Salmo salar) and brown trout (Salmo trutta), the decision to migrate or when to migrate is believed to be influenced by the individual’s metabolic rate (MR) relative its food intake. As MR was expected to be related to behaviour, the potential links between behaviour and metabolic costs was studied. READ MORE
