Basic information: Genome evolution can happen not only through small steps but also through rather large changes that play an important role. For instance, the whole genome set may get duplicated, which has happened at least twice in the common ancestor of the vertebrate lineage. Despite the fact that polyploidy plays an important role in some animal taxa, it largely remains understudied. In our project, we will apply contemporary genome sequencing and assembly methods to analyze the mechanisms leading to polyploidy and its effects on some fish groups where this phenomenon is quite common, specifically cobitid and cyprinid species. We will analyze what happens to different genomic regions after polyploidization and how organisms benefit or suffer from these sudden changes.

Project duration: 1. 4. 2024 – 10. 3. 2027

Principal Investigator: Dr. Vladimir Trifonov Institute of Animal Physiology and Genetics CAS, v. v. i.

Basic information: The project will investigate the extent of local adaptation in current populations of bank voles (Clethrionomys glareolus) in Fennoscandia and assess their potential for adapting to ongoing climate change. Building on the broader understanding that climate change is significantly altering environmental pressures, the project focuses on how species like the bank vole respond to these shifts. Specifically, the study will explore whether adaptive hybridization between C. rutilus and C. glareolus has contributed to local adaptation and could enhance the species’ capacity to cope with future environmental changes. This research will provide insights into evolutionary mechanisms crucial for predicting species resilience and informing conservation strategies.
