  1. 6. Genomic strategies towards the dissection of human complex disease

    Författare :Tesfai Emahazion; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Mapping; complex disease; polymorphism; SNP; association analysis; Alzheimer s disease; oxidative phosphorylation; apoptosis; Genetik; Clinical genetics; Klinisk genetik; Medical Genetics; medicinsk genetik;

    Sammanfattning : Complex diseases are caused by the activities of many genes acting in concert with environmental factors. A major challenge facing human genetic research is to unravel the genetic factors behind complex disorders. LÄS MER

  3. 7. Exploring the Realm of Gene Expression Differences Between White Leghorn and Red Junglefowl Chickens

    Författare :Carolyn Fitzsimmons; Leif Andersson; Finn Hallböök; Dave Burt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; chicken; gene expression; microarray; polymorphism; Genetik; Genetics; Genetik;

    Sammanfattning : In this thesis we attempted to elicit patterns of gene expression that influence phenotype, and that may also have been altered by thousands of years of domestication and selection, between red junglefowl and White Leghorn chickens. Red junglefowl are the wild ancestor to all domesticated chickens, and poultry in general are highly valued as a research animal and food resource. LÄS MER

  4. 8. Phenotypic Processes Triggered by Biological Invasions

    Författare :Philipp E Hirsch; Richard Svanbäck; Skúli Skúlason; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Resource polymorphism; phenotypic plasticity; phenotypic divergence; anti-predator responses; Perca fluviatilis; Rutilus rutilus; Dreissena polymorpha; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Sammanfattning : Individuals within a single population can vary widely in their phenotype e.g. in their body shape. These differences are an important source of biodiversity and they can precede evolutionary divergence within a population. LÄS MER

  5. 9. 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

  7. 10. Population-level consequences of variation

    Författare :Lena Wennersten; Anders Forsman; Olof Leimar; Deepa Agashe; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; colour polymorphism; diversity; establishment success; evolutionary changes; population-level consequences; predation risk; Tetrix subulata; variation; Evolutionary Biology; Evolutionsbiologi;

    Sammanfattning : Consequences of within population variation have recently attracted an increased interest in evolutionary ecology research. Theoretical models suggest important population-level consequences, but many of these predictions still remain to be tested. LÄS MER
