Very glad to see the second chapter of my PhD published in JEB and feel honored that it has been picked as this month's issue "Editor's choice" and cover image! It's been a long and important team effort leading up to these results!

NEW PUBLICATION on stopover ecology of Songbirds during spring migration: After packmor et al. 2020 (Mov Ecol) found that trans-Saharan migrants react differently to weather for migratory departure, we aked ourselves, whether this is also valid for spring migration? 🐦

A single theory for the evolution of sex chromosomes and the two rules of speciation

Sex chromosomes are involved in three major empirical patterns: (i) Y (or W) chromosomes are often nonrecombining and degenerate; (ii) heterogametic offspring (XY or ZW) from interspecific crosses are...

The Australian bogong moth uses the Milky Way as compass during annual 100-mile journey to cool caves. This is shown by a groundbreaking study also revealing that the Earth's magnetic field plays an important role in the navigation of this mysterious moth. www.nature.com/articles/s41...

Every spring, Bogong moths use the starry night sky as a compass to navigate up to 1,000 km towards their alpine migratory goal.

Two hybrid Coenonympha species inherited most of their genome from one parent species but prefer mating with the other! By analyzing chemical profiles, we show that non-random trait sorting likely drives reproductive isolation, fueling hybrid speciation

A single gene underlies male mating morphs in ruff sandpipers, a new Science study finds. The results show how evolutionary changes in a single gene's structure, sequence, and regulation can drive significant diversity within a single species.

Learn more in our new issue: https://scim.ag/4arzNmU

A breeding ruff male (Calidris pugnax) in alert posture scans the breeding area for mating opportunities at Liminka Bay, Finland. Ruff males deploy one of three mating tactics that differ in aggressive and courtship behaviors. Differences in aggression between tactics are tied to concentrations of circulating androgens, which are modulated by the actions of a single gene.
