1. 6. Interaction between crayfish and some microorganisms; Effect of temperature

   Författare :Gül Gizem Korkut; Chadanat Noonin; Kenneth Söderhäll; Javier Diéguez Uribeondo; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Innate immunity, which constitutes the first line of defense in vertebrates, is the only immune system that invertebrates rely on to protect themselves from pathogens. The invertebrate immune system is composed of cellular and humoral components. Cellular immunity is phagocytosis, opsonization and encapsulation. LÄS MER

3. 7. Understanding evolutionary novelty through female-limited polymorphisms

   Författare :Kalle Tunström; Christopher W. Wheat; Rhonda R. Snook; Patrícia Beldade; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; populationsgenetik; Population Genetics;

   Sammanfattning : Understanding how novel traits evolve is a central question in evolutionary biology. However, unraveling the complex genetic and developmental mechanisms underlying trait innovation can be challenging, especially when the trait evolved a long time ago. LÄS MER

4. 8. White Spot Syndrome Virus Interaction with a Freshwater Crayfish

   Författare :Pikul Jiravanichpaisal; Kenneth Söderhäll; Irene Söderhäll; Ellen Kauschke; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; WSSV; crayfish; hematopoietic tissue; cytokine; innate immunity; hemocytes; Biologi; Biology; Biologi;

   Sammanfattning : Viruses are very abundant in water and hence diseases caused by viruses are common in marine organisms. These diseases create great problems for the commercial farming of crustaceans and mussels. LÄS MER

5. 9. The Genetics of Speciation and Colouration in Carrion and Hooded Crows

   Författare :Jelmer Poelstra; Jochen Wolf; Hans Ellegren; Chris Jiggins; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; evolutionary genetics; genomics; birds; next-generation sequencing; pigmentation; pigmentation genetics; eumelanin; social selection; gene expression; population genomics; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : A fundamental goal in biological research is to gain an understanding of the evolutionary processes and genetic elements that drive speciation. Genes responsible for reproductive isolation in young divergent lineages are particularly poorly known. In this thesis, the speciation genetics of carrion (Corvus (corone) corone) and hooded (C. LÄS MER

7. 10. Functional study of hemolymph coagulation in Drosophila larvae

   Författare :Zhi Wang; Ulrich Theopold; Brian Lazzaro; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; innate immunity; hemolymph coagulation; clot components; Drosophila larvae; Molecular Biology; molekylärbiologi;

   Sammanfattning : Many pathogen infections in nature are accompanied by injury and subsequent coagulation. Despite the contribution of hemolymph coagulation to wound sealing, little is known about its immune function. LÄS MER
