Our colleague Ramón Guerra presented his Master’s thesis this week working on mucus tracking among ecotypes and color morphs of Littorina saxatilis. His results shed light on sexual selection in maintaining polymorphisms and limiting gene flow between ecotypes.

Great work and dedication, Ramón! 🎉

One of the bumblebee snails is sporting a fancy mushroom coral accessory. It's called fashion, look it up 😂

Dende 2022, as axudas á investigación non executadas non se reasignan. Parte dos fondos públicos para ciencia pérdense: proxectos que non saen, contratos que non se renovan e talento que marcha, en gran medida por trabas administrativas e prazos ríxidos. 👇🏼 (1/2)

It's #WorldWetlandsDay today! While considering what we can all do to protect these vulnerable ecosystems, we're sharing some botanical illustrations of marsh flowers from 'English Botany', a collaborative work between James Sowerby and Sir James Edward Smith.

Inversions support both parallel and location-specific adaptations in snail ecotypes Replicated hybrid zones between ecotypes established over within shore environmental gradients provide an opportunity to study the genomic architecture of barriers to gene flow. The marine snail Litto...

New results on Littorina fabalis ecotypes! 🐌
Inversions aren't just enabling parallel adaptation to wave exposure in France & Sweden, they're also hotspots for site-specific differences, including a striking color QTL associated with one inversion but only in France.
