1. Adaptive divergence in fission yeast : From experimental evolution to evolutionary genomics
Sammanfattning : How adaptation and population differentiation occur is fundamental to understand the origin of biodiversity. Work in speciation alongside the increased ease of generating genomic data have allowed the exploration of genomic changes relevant to adaptation. LÄS MER
2. Hidden biodiversity in an alpine freshwater top predator : Existence, characteristics, and temporal dynamics of cryptic, sympatric brown trout populations
Sammanfattning : Intraspecific genetic diversity is imperative to the survival of species in a changing environment, and it plays a vital role in ecosystem function. Since this type of diversity can be difficult to detect it is sometimes referred to as “hidden biodiversity”. LÄS MER
3. Ecological systems in space: From islands to contiguous landscapes
Sammanfattning : Dispersal and interaction networks underlie many ecological systems, often dictating spatio-temporal dynamics as well as emergent patterns. Dispersal has implications for establishment for distinct subpopulations of individual species as well as for the emergence of universal spatial patterns and varied community level structures.

4. Determinants of genomic diversity in the collared flycatcher (Ficedula albicollis)
Sammanfattning : Individuals vary from each other in their genetic content. Genetic diversity is at the core of the evolutionary theory. Rooted in a solid theoretical framework developed as early as the 1930s, current empirical observations of genomic diversity became possible due to technological advances. LÄS MER
5. Investigating the impacts of Late Pleistocene climate change on Arctic mammals using palaeogenomics
Sammanfattning : The climatic fluctuations of the Late Pleistocene likely had a large impact on the evolutionary history of Arctic species. Palaeogenomics is a useful tool to shed light on how past populations responded to these climatic shifts and the associated ice sheet dynamics and sea level change. LÄS MER
