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

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...
