  1. 1. Advances in studying the role of genetic divergence and recombination in adaptation in non-model species

    Author : Ramprasad Neethiraj; Christopher Wheat; Sören Nylin; Mathieu Joron; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Recombination; Genetic divergence; Lepidoptera; Genetic variation; Genetic diversity; Holocentric chromosomes; cis-regulatory variation; Allele-specific expression; populationsgenetik; Population Genetics;

    Abstract : Understanding the role of genetic divergence and recombination in adaptation is crucial to understanding the evolutionary potential of species since they can directly affect the levels of genetic variation present within populations or species. Genetic variation in the functional parts of the genome such as exons or regulatory regions is the raw material for evolution, because natural selection can only operate on phenotypic variation already present in the population.

  2. 2. Assessing and monitoring genetic patterns for conservation purposes with special emphasis on Scandinavia

    Author : Anna Palmé; Nils Ryman; Linda Laikre; Kerry Naish; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; biological diversity; conservation genetics; management unit; spatial genetic structure; sympatric populations; genetic monitoring; release of alien populations; northern pike; brown trout; harbour porpoise; Biology; Biologi; populationsgenetik; Population Genetics;

    Abstract : Genetic variation is essential for biological evolution, for maintaining viability of populations, and to ensure ecosystem resilience. Increased human exploitation and environmental change result in rapid loss of biological variation, including genetic diversity. READ MORE

  3. 3. Effects of warming on the green alga Cladophora glomerata : Ecological and genetic responses

    Author : Jenny Zie; Pauline Snoeijs; Mats Grahn; Anna Godhe; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; AFLP; Baltic Sea; Cladophora glomerata; climate change; community ecology; genome scan; global warming; selection; marin ekologi; Marine Ecology;

    Abstract : Since the beginning of the 20th century, average global surface temperature has increased ~0.7 °C and the current scenarios predict that it will continue to rise additional 2-4 °C during the 21st century. READ MORE

  4. 4. Biochemical and genetic markers after subarachnoid haemorrhage

    Author : Ludvig Z Csajbok; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; subarachnoid haemorrhage; biochemical marker; genetic marker; outcome;

    Abstract : ABSTRACT Background: Subarachnoid haemorrhage is a devastating disease with high morbidity and mortality despite novel treatment options are available. There are no established methods to measure the brain damage occurring due to the bleed and its complications and to predict early neurological outcome of the disease. READ MORE

  5. 5. Genetic and epidemiological aspects of implantation defects : Studies on recurrent miscarriage, preeclampsia and oocyte donation

    Author : Evangelia Elenis; Agneta Skoog Svanberg; Alkistis Skalkidou; Gunilla Sydsjö; Helena Åkerud; Anja Pinborg; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; genetic polymorphism; gestational hypertensive disorders; Histidine-rich glycoprotein; HRG; implantation defect; oocyte donation; placentation; preeclampsia; recurrent miscarriage; SNP.; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Abstract : Implantation requires complex molecular and cellular events involving coagulation, angiogenesis and immunological processes that need to be well regulated for a pregnancy to establish and progress normally.  The overall aim of this thesis was to study different models associated with atypical angiogenesis, impaired implantation and/or placentation, such as recurrent miscarriage (RM), oocyte donation (OD) and preeclampsia.
