1. 11. What modulates telomere dynamics? : Inheritance, developmental effects, and physiological challenges

   Författare :Ye Xiong; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Telomere; Telomere dynamics; Telomere length; telomere inheritance; Zebra finch; Immune challenge; Heritability; Taenopygia guttata; Physiological parameter;

   Sammanfattning : Telomeres are the conservative sequence repeats located at the end of linear chromosomes that have been the focus of intensive research across many disciplines over the last four decades. They function as a cap to protect the chromosome ends from fusion to other chromosomes and to prevent chromosome degradation. LÄS MER

3. 12. Clinical and genetical aspects of Celiac Disease

   Författare :Audur Gudjonsdottir; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; celiac disease; sib-pair; screening; genome-wide scan; linkage analysis; heritability; genotypes; DQ2-negative; phenotypes; autoimmune disease;

   Sammanfattning : Celiac disease (CD), or gluten-sensitive enteropathy, is one of the most common chronic diseases in childhood but is diagnosed in all ages. CD is a genetically driven immunological intolerance to dietary gluten. Th e treatment is a gluten-free diet. LÄS MER

4. 13. LIVING WITH PARASITES: AVIAN MALARIA, TELOMERE LENGTH AND LIFE HISTORY TRADE-OFFS

   Författare :Asghar Muhammad; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Avian malaria; Plasmodium; qPCR; parasitemia; life history; reproduction; survival; feather growth; MHC; telomere length; heritability; telomere loss; fitness; wild population; Acrocephalus arundinaceus; Delichon urbica;

   Sammanfattning : Haemosporidia is a well-studied group of parasites, which infect mammals, reptiles and birds and use blood sucking vectors for their transmission. By conducting natural population studies and experimental infections, We have been able to detect and quantify Haemosporidia from avian blood to investigate how these pathogens affect their avian hosts.

5. 14. Interaction between dispersal and behavioural syndromes - empirical approach in a fragmented population of passerine birds

   Författare :Gregory Daniel; Blandine Doligez; Lars Gustafsson; Thierry Boulinier; Uppsala universitet; []
   Nyckelord :dispersal; behavioural syndromes; heritability; personality traits; neophobia; aggressiveness; risk-taking behaviour; collared flycatcher; Ficedulla albicollis; dispersion; syndromes comportementaux; héritabilité; traits de personnalité; néophibie; aggressivité; prise de risque; gobemouche à collier; Ficedulla albicollis; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

   Sammanfattning : Dispersal is a key life history trait for ecological and evolutionary processes in wild populations. The latest research has particularly focused on the correlation between behavioural traits and dispersal, in order to emphasize the existence of behavioural syndromes of dispersal, and on the estimation of the genetic basis of the dispersal behaviour.

7. 15. Plant phenology in seasonal environments

   Författare :Elsa Fogelström; Johan Ehrlén; Johan P. Dahlgren; Arthur Weis; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Autumn phenology; Cardamine pratensis; evolutionary ecology; heritability; herbivore preference; fitness components; flowering time; growing season length; life-history; Lathyrus vernus; natural selection; population differentiation; phenology; spring phenology; Plant Ecology; växtekologi;

   Sammanfattning : Phenology, or the seasonal timing life-history events such as emergence, reproduction and senescence will determine the outcome of interactions between plants and both abiotic and biotic aspects of the environment. Such timing is therefore of utmost importance for plants in seasonal environments. LÄS MER
