Congrats Kerry! 🎉🍻🎉

The dataset is a valuable resource for:
🔹 Scientists studying road ecology
🔹 Policymakers developing mitigation strategies
🔹 Conservationists aiming to reduce roadkill impacts.

This work provides a foundation for better wildlife-vehicle conflict management worldwide. 🚗🌿

By consolidating data from systematic surveys and opportunistic observations, this dataset supports infrastructure ecology & terrestrial vertebrate conservation.

It also helps minimize redundant data collection, facilitating large-scale research.

What can this dataset be used for?
✅ Analyzing roadkill rates across species & regions
✅ Understanding how roads & landscapes influence mortality risk
✅ Identifying species vulnerability to traffic
✅ Evaluating potential local extinction risks

Wildlife-vehicle collisions are a major threat to biodiversity and have socioeconomic costs due to traffic accidents.

To better understand these impacts, we compiled roadkill data from 1971 to 2024, integrating published & unpublished records. 📊📍

This paper was part of my postdoc at IREC-CSIC-UCLM, and was possible thanks to the participation of great coauthors. However, I particularly want to highlight my brilliant supervisors, François Mougeot and @anabenlop.bsky.social , whose personal and academic support has been extraordinary!

Our findings highlight:
🔹 Conservation must adapt to biodiversity shifts.
🔹 Continuous monitoring is crucial.
🔹 PAs are valuable, but further action is needed to halt species decline.

Are Protected Areas effective?
✅ The extent of hotspots within PAs increased from 21.8% to 29.4%.
❌ However, overall species richness declined, particularly outside PAs.

This suggests that PAs can be effective, but they are not enough. 🚨

We found significant shifts in hotspots ⬇️
➡️ Two regions in central and NE Spain accounted for over 50% of both historical and current hotspot areas.
➡️ NW Spain lost over 50% of its hotspots

We focused on steppe birds, one of the most threatened bird groups in Europe, and analysed hotspot distribution in Spain across two time periods:
📍 1998–2002 (historical)
📍 2014–2023 (current)

We analysed how biodiversity hotspots have shifted over the past two decades and assessed the effectiveness of Protected Areas (PAs) in conserving these species. 🧵👇

This is the closest image of Saturn ever captured by the Cassini spacecraft. It shows the planet in a majestic and serene light, with its rings in the foreground. The planet's golden hues are highlighted by the sunlight filtering through its upper atmosphere. A notable feature is the intriguing hexagonal storm at the north pole, a unique weather phenomenon in our solar system. The image provides an unparalleled, close-up perspective, inviting viewers to appreciate the intricate details of Saturn's cloud bands and the sheer vastness of its ring system. It is a stunning portrayal of the beauty and complexity of this gas giant, captured from a vantage point closer than any human-made probe has ventured before.

This is the closest photo of Saturn ever taken.
