  2. 6. Genetic Disequilibria and the Interpretation of Population Genetic Structure in Daphnia

    Author : Lars M. Berg; Xavier Vekemans; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; breeding system; linkage disequilibrium; dispersal; genetic structure; Daphnia pulex; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; naturvårdsbiologi; Conservation Biology;

    Abstract : Understanding the processes that shape the spatial distribution of genetic variation within species is central to the evolutionary study of diversification and demography. Neutral genetic variation reflects past demographic events as well as current demographic characteristics of populations, and the correct interpretation of genetic data requires that the relative impact of these forces can be identified.

  4. 7. Hybridisation between introduced brown hares and native mountain hares in Sweden

    Author : Carl-Gustaf Thulin; Uppsala universitet; []

    Abstract : To investigate the extent and effect of hybridisation between wild sympatric populations of introduced brown hares (Lepus europaeus) and native mountain hares (L.timidus) in Sweden, the geographic distribution of genetic variation in mitochondrial DNA (mtDNA) and nuclear DNA microsatellite markers were analysed within and between the two species and their presumed hybrids.

    Abstract : The recent emergence of a number of new viral diseases as well as the re-emergence of tuberculosis (TB), indicate an urgent need for new drugs against viral and bacterial infections.Coronavirus nsp1 has been shown to induce suppression of host gene expression and interfere with host immune response.

  6. 9. Advancing Evolutionary Biology: Genomics, Bayesian Statistics, and Machine Learning

    Author : Tobias Andermann; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computational biology; bioinformatics; phylogenetics; neural networks; NGS; target capture; Illumina sequencing; fossils; IUCN conservation status; extinction rates;

    Abstract : During the recent decades the field of evolutionary biology has entered the era of big data, which has transformed the field into an increasingly computational discipline. In this thesis I present novel computational method developments, including their application in empirical case studies. READ MORE

  7. 10. Developmental phase transitions in Norway spruce : a molecular approach to identify regulatory mechanisms

    Author : Daniel Uddenberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Plant development proceeds through distinct phases that are controlled by complex networks of regulatory genetic circuits and fine-tuned by environmental and endogenous cues. Many of these regulatory networks have been unraveled in annual and perennial angiosperms, while they remain predominantly unknown in ecologically and economically important gymnosperm species such as the conifers.
