1. 1. Evolutionary consequences of sex-specific selection

   Författare :Josefine Stångberg; Elisabeth Bolund; Elina Immonen; Jennifer Perry; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Caenorhabditis remanei; Callosobruchus maculatus; sex-specific selection; sexual selection; experimental evolution; intralocus sexual conflict; life history evolution; sexual dimorphism; trade-offs; Quantitative genetics;

   Sammanfattning : Sex-specific selection is widespread, evident by the evolution of sexual dimorphism in many traits in sexually reproducing taxa. The reason why the sexes may experience selection that differs in direction or magnitude is often linked to the reproductive strategies associated with the sex-specific reproductive physiology.

3. 2. Metapopulations dynamics and sex-specific resource allocation in Silene dioica

   Författare :Elisabet Peedu; Pär Ingvarsson; Barbara Giles; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Silene dioica; Skeppvik Archipelago; Metapopulation Dynamics; Population Genetic Structuring; Genetic Diversity; Gene Flow; Sex-Specific Resource Allocation; Cost of Reproduction; Life-History Theory; Sexual Dimorphism; Reproductive Effort; biology; biologi; evolutionär genetik; evolutionary genetics; ekologisk botanik; Ecological Botany;

   Sammanfattning : Rising archipelagos provide unique settings for the study of the temporal and spatial dynamics of their biota. This offers the possibility to study the ecology and genetics of early successional processes; both between islands that differ in age and within islands when already established organisms have to keep pace with the changing environment.

5. 4. Thioredoxins and gene regulation in the Drosophila germline

   Sammanfattning : Spermatogenesen är i många organismer en av de mest dramatiska förvandlingar som en cell kan genomgå – en vanlig, rund, diploid cell omvandlas till en nålformad, haploid cell med ett tätt packat cellmaskineri. I bananfluga, Drosophila melanogaster, innebär denna process flera karaktäristiska stadier. LÄS MER

7. 5. Antiepileptic drug utilization : need of sex-specific information and decision support

   Författare :Linnéa Karlsson Lind; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Antiepileptic drugs are used for the treatment of epilepsy and for other neurological and psychiatric conditions, and therefore is prescribing of antiepileptic drugs a concern for physicians from many disciplines. The age and sex-specific prevalence, as well as the role of sex and gender aspects, vary between the conditions for which antiepileptic drugs are used. LÄS MER
