  1. 6. Population divergence at small spatial scales : – theoretical and empirical investigations in perch

    Författare :Sara Bergek; Mats Björklund; Teija Aho; Sarah Goodacre; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Perca fluviatilis L.; Perch; Small scale genetic differentiation; Morphometrics; Isolation by distance; Dispersal; Gene flow; Microsatellites; Spatiotemporal stability; Barriers; Biology; Biologi; Terrestrial; freshwater and marine ecology; Terrestrisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

    Sammanfattning : Genetically structured populations arise when gene flow between groups of individuals is hindered by geographical, behavioural or temporal barriers. The identification of such groups is important for understanding evolution and has large implications for conservation concern. LÄS MER

  3. 7. Biodiversity in Swedish Cyprinid Fish: Insights Into Processes of Divergence

    Författare :Marnie H Demandt; Mats Björklund; Erik Petersson; Brent Emerson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; speciation; hybridization; bottleneck; genetic drift; phylogeny; speciation rates; common bream; white bream; roach; Swedish cyprinid fish; Cyprinidae; Biology; Biologi;

    Sammanfattning : Uncovering and understanding the processes that have led to the biological diversity we observe today are of fundamental interest in biology. Since direct observation of speciation is usually impossible, knowledge about the processes behind species formation can be gathered by studying mutations, natural/sexual selection, and genetic drift.

  4. 8. Developing guidelines in nursing care of children with Autism Spectrum Disorder in high technology health care settings

    Författare :Ingalill Gimbler Berglund; Karina Huus; Karin Enskär; Berit Björkman; Bengt Fridlund; Elisabeth Ericsson; Marie Proczkowska-Björklund; Mats Eriksson; Jönköping University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesia; autism; children; guidelines; nurses; participation; radiology;

    Sammanfattning : Introduction. The high technology environment such as a radiology and anaesthesia department in a typical health care setting can many times be a frightening environment for children. Children with neurodevelopmental disorders, such as Autism Spectrum Disorder (ASD), have problems with communication and social interaction. LÄS MER

  5. 9. Quantitative Trait Evolution in a Changing Environment in a Seed Beetle

    Författare :Lára R. Hallsson; Mats Björklund; Derek A. Roff; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantitative trait; genetic variance; environmental change; temperature; seed beetle; sexual dimorphism; plasticity; inheritance; Animal Ecology; Zooekologi;

    Sammanfattning : During the last decades the climate has been changing more rapidly than in the preceding periods. This is for instance characterized by an increase in temperature. Interestingly, such changes in the environment are not necessarily constant over time as they often show high levels of fluctuation. LÄS MER

  7. 10. Plumage Colours and the Eye of the Beholder : The Ecology of Colour and its Perception in Birds

    Författare :Olle Håstad; Mats Björklund; Innes Cuthill; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; ultraviolet; colour vision; opsin; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Virtually all diurnal birds have tetrachomatic vision based on four different colour receptors. As a result, birds are potentially able to perceive their environment in twice as many colours as humans and four times as many colours compared to most other mammals, which are dichromatic. LÄS MER
