Last chapter of my student Masoud Nazarizadeh's thesis, showcasing the emergence of host-selected parasite lineages in the presence of gene flow, was just published in MBE. Great job, Masoud! doi.org/10.1093/molb...
Host-associated Genetic Differentiation in the Face of Ongoing Gene Flow: Ecological Speciation in a Pathogenic Parasite of Freshwater Fish
Abstract. Adaptive evolution in response to varying environments, leading to population divergence, is among the most intriguing processes of speciation. H

The retreat of glaciers and the creation of new coasts: a team led by a glaciologist from FSc USB published a groundbreaking study in Nature Climate Change doi.org/10.1038/s415...
New coasts emerging from the retreat of Northern Hemisphere marine-terminating glaciers in the twenty-first century - Nature Climate Change
As marine-terminating glaciers retreat, they reveal new coastlines in many regions. Here the authors use satellite data to quantify these changes for the Northern Hemisphere, finding that between 2000...

Island size vs. genetic load in Galapagos mockingbirds. Finally it’s out, congrats to Jakub Vlček! Thanks to all collaborators. doi.org/10.1111/mec....
Genomes of Galápagos Mockingbirds Reveal the Impact of Island Size and Past Demography on Inbreeding and Genetic Load in Contemporary Populations
Restricted range size brings about noteworthy genetic consequences that may affect the viability of a population and eventually its extinction. Particularly, the question if an increase in inbreeding...

The last paper from my PhD is finally out in Bulletin of SSB with @3rdreviewer.bsky.social! We used theory and supervised machine learning to learn how to disentangle uncertain histories of speciation and introgression.

Study shows proliferation of non-native plants is driver of insect invasions
https://botany.fyi/4aer6k

A global study has revealed that insect invasions are being driven by the proliferation of non-native plants. This can disrupt ecological processes, often leading to serious economic impacts.
