    Sammanfattning : This study deals with the changes in color that arise in space, primarily simultaneous contrast in three dimensions. The typical account of simultaneous contrast is that the contrast phenomenon occurs between two or more color surfaces seen together, thus affecting one another. LÄS MER

  3. 2. Signaling for color change in melanophores : and a biosensor application

    Författare :Annika M. Karlsson; Samuel Svensson; Margareta Wallin; Linköpings universitet; []
    Nyckelord :color change; melanophores; tyrosine; phosphorylations; melatonin; nitric oxide; MEDICINE; MEDICIN;

    Sammanfattning : Melanophores are dark brown pigment cells located in the skin of fish, amphibia, reptiles, and many invertebrates. The color of the animal can change via rearrangement of pigment granules, melanosomes, in the cells. The dark melanophores can either hide colorful cells so that the animal appears dark, or let through colors from underneath. LÄS MER

    Sammanfattning : The aim of this thesis is to investigate lexical replacement processes from several complementary perspectives. It does so through three studies, each with a different scope and time depth. LÄS MER

  7. 5. Fish population responses to climate change : Causes and consequences

    Författare :Matilda L. Andersson; Peter Eklöv; Brian Hayden; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; browning; climate change; DOC; intraspecific variation; metabolism; resource use; warming;

    Sammanfattning : Lake environments are heterogeneous, and animals show a variety of adaptations to deal with this heterogeneity. Fish often show intraspecific variation in diet, metabolism, and behavior, corresponding to their habitat use. LÄS MER
