Pan‐Continental Genomic Analysis of Eurasian Perch Uncovers Global Diversity Hotspots and Postglacial Recolonization Patterns

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We reconstructed the postglacial recolonization history of Eurasian perch using mitochondrial and nuclear genomic data spanning Europe and Western Siberia. The analyses revealed multiple glacial refugia and extensive secondary admixture, reflecting a dynamic history of range expansion and contact among divergent lineages.

High Geomagnetic Reversal Frequency During the Middle to Late Ediacaran (∼570 Ma) Constrained by Integrated Magneto‐ and Cyclostratigraphy

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Ediacaran–Cambrian (∼635–539 Ma) geomagnetic field is characterized by unusually high reversal rates and markedly weakened field strength. Estimates of these reversal frequencies can reveal key aspects of deep Earth dynamics and their potential influence on surface environments and early complex life.

When South Meets North: A Joint Contact Zone Coinciding With Environmental Gradients in Three Boreal Tree Species

open access: yesMolecular Ecology, Volume 35, Issue 8, April 2026.
ABSTRACT Post‐glacial recolonisation of Fennoscandia created secondary contact zones in many species, offering opportunities to study how gene flow and selection contribute to their establishment and maintenance. Here, we analyse genomic data from three boreal tree species—Picea abies, Betula pendula and Pinus sylvestris—sampled along a latitudinal ...
