16. Drivers of evolutionary change in Podospora anserina
Sammanfattning : Genomic diversity is shaped by a myriad of forces acting in different directions. Some genes work in concert with the interests of the organism, often shaped by natural selection, while others follow their own interests. The latter genes are considered “selfish”, behaving either neutrally to the host, or causing it harm. LÄS MER
17. Rates and patterns of molecular evolution in avian genomes
Sammanfattning : Evolution is the change in inherited characteristics of a population through subsequent generations. The interplay of several evolutionary mechanisms determines the rate at which this change occurs. LÄS MER
18. Speciation genomics in Ficedula flycatchers
Sammanfattning : Understanding what evolutionary processes have shaped patterns of genomic differentiation between species is a major aim of speciation genomics. However, disentangling the role of different processes that generate similar patterns remains a substantial challenge. LÄS MER
19. The evolution of sexual dimorphism and its genetic underpinnings
Sammanfattning : Sexual dimorphism often constitutes the largest phenotypic variance within species but it is puzzling how sexual dimorphisms evolve because most of the genome is shared between the sexes. Sexually antagonistic (SA) selection on a shared genome sets the stage for intralocus sexual conflict. LÄS MER
20. Symbiosis in Arbuscular Mycorrhizal Fungi : Unearthing genomic signatures
Sammanfattning : Arbuscular mycorrhizal (AM) fungi have been on earth since 470 million years ago. AM fungi form mutualistic symbiosis with most terrestrial plants and thus, are thought to have played important roles in land colonization together with plants. LÄS MER
