Illuminating range shifts through evolutionary FIASCO*:
contrasting FaIling And Successful ColOnizations in replicated wild populations
A joint effort among the Stazione Zoologica Anton Dohrn, University of Ferrara, and other national and international researchers coordinated by Francesca Raffini and funded by the European Union - Next Generation EU
*What is a fiasco?
In Italian, a fiasco is literally a bottle (a flask encased in a straw basket, see the picture below) but it has also a figurative meaning: an utter failure. The linguistic evolution of fiasco from flask to flop is still obscure, similarly to our understanding of the evolution of ecological success in small populations, that will be addressed by the FIASCO project.
Project overview
Anthropogenic disturbances and climate changes can lead to rapid population declines, shifted geographic distributions, or adaptation to new conditions. The drivers and implications of this disparity in species’ responses remain puzzling. We explore the evolutionary mechanisms underlying range shifts by contrasting naturally replicated dispersal events in a marine snail. We leverage multidimensional information from whole genomes including chromosomal structural variants, phenotypic traits, and local habitats to clarify why some range shifts succeeded while others ended in a fiasco, advancing our understanding of the drivers of ecological success.
These findings will contribute to the urgently needed improvement of knowledge of the fundamental mechanisms that originate and maintain biodiversity to inform effective actions in wildlife management.
Our results will be disseminated to the scientific community, stakeholders, and citizens to draw attention to biodiversity research, increase social trust, and build resilience against the global decline of biodiversity, economy, and society.

Snail hunting in weird spots in England! 🐚 🔍🇬🇧
We typically collect snails on rocky shores, but David and Roger explored some unusual sites:
💧 Salts Hole – Looks like a freshwater pond but is fed by a saltwater spring! Snails lived on submerged branches in the mud.
🌊 Missel Marsh – Reached by wading through tidal channels. Tiny, colorful snails thrived in shallow shingle pools.
Big thanks to local wardens for guiding us to these hidden spots!

Sampling in sweden
September 2024
Sampling day near Tjärnö—one of 🇸🇪Sweden’s most exposed coastal sites. The smooth granite rocks, scraped bare by glacial ice, make a tough home for snails. To survive here, they have to be small enough to cling to crevices, avoiding the relentless waves.
Nature finds a way—even in the harshest conditions. 🐌🐚🌊

Sampling in maine
August 2024
Recently, while sampling for the FIASCO project, April Blakeslee captured striking photos of Littorina saxatilis 🌊🐌 from Southport, Maine 🇺🇸, showcasing the remarkable variety in their forms and colors 🐚✨. She then transported these snails to Tjärnö, Sweden✈️🇸🇪 where the FIASCO team conducted detailed phenotypic measurements 🔍🔬 and dissected the specimens to gather DNA 🧬, reproductive data and examine symbionts, including trematode parasites and commensal ciliates 🦠.
The trematodes are particularly intriguing as they are multi-host, trophically transmitted parasitic castrators 🔪 - significantly impacting snail populations while also playing a crucial role in broader ecological networks. Their presence ties these snails to numerous other species, highlighting the intricate web of interactions within marine ecosystems.
Stay tuned for more insights from the FIASCO project as we continue exploring these complex host-parasite relationships!

ww - Winklewatch: a community science project on snail colour
July 2024
Why are periwinkles 🌊🐚 so colourful🌈? Is this related to adaptation to local environments and colonisation success?
Help us finding this out and become a WinkleWatcher! How? Check our website: https://littorina.at.biopolis.pt/winklewatch
We call both scientists and non-scientists 🤝💪 from across the species distribution range (see the blue areas in the map below) to submit images of their local snails in order to spark curiosity about colour evolution and gather a large dataset.

Getting BOLD: our recording adventure
July 2024
The team is working hard to test different setups to measure behavioural differences such as boldness in our snail. We are playing around with camera angles, animal containers, lighting, zoom levels, and other video settings. By using video recordings instead of watching the animals directly, we are making sure that our results are super repeatable and efficient, and avoiding any sneaky biases. This way, we can capture the boldness of these little creatures effectively every time!

p.s. Have you noticed that the snail in the pics is not L. saxatilis? We’re using former data and another species from aquaculture to avoid affecting natural populations. The last step will be to test the optimized protocol in our target snail.
David meets our snail
June 2024
David explored the stunning Pointe de Penvins in the Brittany coast (France), sampling Littorina snails for the first time. He collected L. saxatilis but also some L. littorea - a common mix-up for non-experts due to their similar shell and overlapping habitat - and learned about the subtle differences between these species and the beauty of coastal fieldwork. Watch out for a fresh, eager malacologist!

The greatest northern snail
June 2024
We successfully got our first thriving natural population from collaborators! Where do these snail come from? Hint 1: we're in Europe. Hint 2: there is still some snow in summer. Hint 3: they are the northernmost snail of our sampling design. Hint 4: we're very grateful to our teammates at the Nord University (Bodo, Norway).
Can you spot the Littorina snail in the pictures below?

Getting ready for fieldwork
June 2024
Fieldwork starts in the lab! Less exciting tasks, such as filling 3000 microtubes (with what? Coming soon!), are necessary for sampling expeditions but can be fun thanks to teamwork. After pouring lab glassware with reagents, it's time to empty the cocktail bottles! A huge thank you to all the volunteers that contributed to this crucial step!
