1. 1. Facets of Fun: On the Design of Computer Augmented Entertainment Artifacts

   Författare :Sus Lundgren; Chalmers tekniska högskola; []
   Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; game mechanics; animal expression transfer; Game Design Patterns; the Iron Horse; design tools; remnants; slow technology; the Forces-Clashes-Remnants model; clashes; myTHeme; Interactive entertainment artifacts; forces; the Interactive Quilt; MultiMonsterMania; The Hatchery;

   Sammanfattning : This thesis discusses the design of interactive entertaining artifacts such as computer games and computer augmented toys, games and objects. The aim has been to find and/or develop design tools i.e. LÄS MER

3. 2. Individual variation in behaviour: personality and performance of brown trout in the wild

   Författare :Bart Adriaenssens; Göteborgs universitet; []
   Nyckelord :behavioural syndromes; personality; life-history; boldness; hatchery; survival; growth; foraging; anti-predator behaviour; learning; brown trout;

   Sammanfattning : Individuals from the same population often show very different behaviour. These differences, when consistent across time, are referred to as animal personality or behavioural syndromes. Explaining the occurrence of animal personality from an evolutionary perspective has however proven a difficult issue to tackle. LÄS MER

4. 3. Environmental influences on the behavioural ecology of juvenile salmonids – the importance of rearing density

   Författare :Sofia Brockmark; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; rearing density; structural complexity; familiarity; antipredator response; limited attention; social status; growth rate; smolt status; fin erosion; post-release performance; hatchery supplementation; brown trout; Atlantic salmon;

   Sammanfattning : Background and aims: Early environmental conditions are known to influence the phenotypic development of animals, including behavioural alterations. The overall aim of this thesis is to investigate the effects of density, social stability and structural complexity on growth, behaviour, and survival in the wild, using juvenile brown trout (Salmo trutta) and Atlantic salmon (Salmo salar) as model species.

5. 4. Stress Coping Strategies in Brown Trout (Salmo Trutta): Ecological Significance and Effects of Sea-Ranching

   Författare :Daniel Brelin; Svante Winberg; Erik Petersson; Jörgen Johnsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoophysiology; Stress-coping-strategies; Animal-personalities; Behavioral-syndromes; Brown trout; Salmo trutta; Catecholamines; Sexual maturation; Hatchery; Phenotype; Learning; Zoofysiologi; Biology; Biologi;

   Sammanfattning : Two distinct stress coping strategies, proactive and reactive, have been stated in various animal studies, each associated with a set of behavioural and physiological characteristics. In a given challenging situation, proactive animals show more aggression, a higher general activity and a predominant sympathetic reaction. LÄS MER

7. 5. Migration and quality of landlocked Atlantic salmon smolt : Implications for conservation and management

   Författare :Johnny R Norrgård; Eva Bergman; Larry A Greenberg; Monika Schmitz; Martyn Lucas; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acoustic telemetry; hatchery; life history; migration mortality; regulated rivers; Salmo salar; salmon; smolt; trout; Biology; Biologi;

   Sammanfattning : Atlantic salmon Salmo salar has a complex life cycle, including long migrations and habitat shifts for both juveniles and adults. As such, salmon populations are vulnerable to habitat degradation and fragmentation along their migratory routes. LÄS MER
