  1. 1. Behavioural aspects of conservation breeding : Red junglefowl (Gallus gallus) as a case study

    Författare :Jennie Håkansson; Per Jensen; Elsbeth McPhee; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Behaviour; Conservation; Red junglefowl; Gallus gallus; Captivity; Ethology and behavioural ecology; Etologi och beteendeekologi;

    Sammanfattning : Ett stort antal utrotningshotade djurarter ingår idag i bevarandeprogram världen över. Små populationer hålls då i skyddade miljöer, exempelvis i djurparker, och i många fall är målet att återintroducera djur till naturen. LÄS MER

  3. 2. Survival of the Tamest : The Domesticated Phenotype in Red Junglefowl Selected for Tameness

    Författare :Rebecca Katajamaa; Per Jensen; Dominic Wright; Ruth C. Newberry; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; domestication; chicken; red junglefowl; tameness; brain size; behaviour; cognition; body size;

    Sammanfattning : Early animal domestication was probably associated with reduced fear of humans. Domestication is a process in which animals adapt to humans and the captive environment provided by humans. Selection on tameness as the only trait has previously been found to generate changes in other phenotypes in different animal species. LÄS MER

  4. 3. Behavioural differences and genetic relationships between four captive populations of red junglefowl (Gallus gallus) : possible implications for conservation

    Författare :Jennie Håkansson; Linköpings universitet; []
    Nyckelord :Red junglefowl; behavioural differences; genetic relationships; captive populations; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Conservation of species is to a large extent carried out by zoos where animals are kept in small populations under protected conditions. The ultimate goal of such ex situ conservation programs is to eventually reintroduce the animals into natural habitats to provide support for the survival of the species. LÄS MER

  5. 4. Pulsed Electric Field Treatment of Plant Tissue

    Författare :Mustafa Fincan; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bimodal Fickian diffusion model; Food and drink technology; Livsmedelsteknik; generalized Maxwell model; onion Neutral Red; visualization; red beetroot; potato; epidermis; plant tissue; electroporation; Cell permeabilization; Pulsed electric field; PEF;

    Sammanfattning : A pulsed electric field (PEF) is a newly emerged non-thermal food processing technology which has characteristic effects on the cell membrane. PEF processing involves subjecting food to short, repeated pulses of a high electric field between an anode and a cathode. LÄS MER

  7. 5. Polysaccharides from red and green seaweed : Extraction, characterisation and applications

    Författare :Niklas Wahlström; Ulrica Edlund; Fredrik Gröndahl; Federica Chiellini; KTH; []
    Nyckelord :biorefinery; seaweed; macroalgae; Ulva; Porphyra; ulvan; porphyran; cellulose; gelatin; hydrogel; heavy metal; methylene blue; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Cultivation of seaweed has been conducted for centuries in Asia, but is largely undeveloped in Sweden even though there is potential for this industry. Seaweed offers benefits compared with land-based biomass cultivation. LÄS MER
