    Author : Jessica Abbott; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; embryologi; ontogeni; animal morphology; embryology; Utvecklingsbiologi; Damselflies; Colour polymorphism; Development; Frequency-dependence; Morphology; growth animal ; ontogeny; Animal anatomy; Development biology; Djurs anatomi och morfologi; Population divergence; Animal ecology; Djurekologi;

    Abstract : This study has involved investigation of number of populations of the damselfly Ischnura elegans over several years, looking at frequency changes over time, morphological differences between the sexes and the morphs, differences in growth rate and development time, differences in fecundity between the morphs, and genetic differentiation between populations.

  3. 8. Novel Treatment Modalities for High-Risk Neuroblastoma Studies in Animal Models

    University dissertation from Uppsala : Universitetsbiblioteket

    Author : Dieter Fuchs; Uppsala universitet.; [2009]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; neuroblastoma; bevacizumab; SU11248; GMX1778; GMX1777; animal model; VETERINARY MEDICINE Medicine; VETERINÄRMEDICIN Medicin;

    Abstract : Neuroblastoma, the most common extracranial solid tumor of childhood, is a heterogeneous tumor. In some patients, the tumor can go into spontaneous regression and disappear whereas other patients have rapidly growing tumors with a poor prognosis. READ MORE

  4. 9. Genetic Heteroscedasticity for Domestic Animal Traits

    University dissertation from Uppsala : Sveriges Lantbruksuniversitet

    Author : Majbritt Felleki; Högskolan Dalarna.; [2014]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Quantitative genetics; genetic heteroscedasticity of residuals; genetic heterogeneity of environmental variation; genetic heterogeneity of residual variance; double hierarchical generalized linear models; teat count in pigs; litter size in pigs; milk yield in cows; somatic cell count in cows; Komplexa system - mikrodataanalys;

    Abstract : Animal traits differ not only in mean, but also in variation around the mean. For instance, one sire’s daughter group may be very homogeneous, while another sire’s daughters are much more heterogeneous in performance. The difference in residual variance can partially be explained by genetic differences. READ MORE

  5. 10. Modelling animal populations

    University dissertation from Uppsala : Sveriges Lantbruksuniversitet

    Author : Åke Brännström; Umeå universitet.; [2004]
    Keywords : population model; stochastic population model; population dynamics; discrete time model; Beverton-Holt model; Skellam model; Hassell model; Ricker model; first principles; coupled map lattice; CML; area integral; square function; Mathematics; matematik;

    Abstract : This thesis consists of four papers, three papers about modelling animal populations and one paper about an area integral estimate for solutions of partial differential equations on non-smooth domains. The papers are: I. Å. Brännström, Single species population models from first principles. READ MORE
