Caio Graco-Roza @gracoroza.bsky.social · 23/12/2024This says a lot about the fact that most prestigious international journals are in western countries. More of them in Eastern countries and we would have another setting of holidays. On a funny note, here in Finland, the most relevant call for funding has its deadline on January 8th. It bugs me… 000

Caio Graco-Roza @gracoroza.bsky.social · 04/12/202411/1 🙌 Acknowledgements This work was only possible thanks to the incredible amount of open-access data and a huge collaborative effort involving over 20 authors from around the world. 🌍 This research was part of the Blue Green Biodiversity (BGB) initiative, a collaboration between EAWAG and WSL. 110
Caio Graco-Roza @gracoroza.bsky.social · 04/12/202410/ 🚀 What’s Next? To truly understand biodiversity loss, we need global collaboration, long-term monitoring, and policy changes that integrate functional diversity into urban planning and conservation. 110
Caio Graco-Roza @gracoroza.bsky.social · 04/12/20249/ 💡 Why This Matters Ecosystem resilience relies on functional diversity—the traits that allow ecosystems to function 🌱⚙️. Homogenised traits mean ecosystems are less adaptable to change 🔄⚠️. Conservation strategies must: Protect minimally impacted habitats 🌳. Promote habitat heterogeneity 🌾. 120
Caio Graco-Roza @gracoroza.bsky.social · 04/12/20248/ 🔄 Fig. 5: Species vs Trait Mismatch -While 59.3% of datasets show species and traits changing in the same direction, traits are disproportionately homogenised 📏🌱. -No differences in effect magnitude, but baseline pressure shapes responses. -Exponential ↗️ and saturating ➡️ turnover often pair. 120
Caio Graco-Roza @gracoroza.bsky.social · 04/12/20247/ 🔄 Fig. 4: The Shape of Turnover Species and trait turnover face tipping points under intense pressure. Saturating responses dominate species turnover (43.7%) 🐟🌳, showing high sensitivity to small pressures. Exponential responses dominate traits (34.4%) 🌆🌱, especially in urban areas. 110
Caio Graco-Roza @gracoroza.bsky.social · 04/12/20246/ 📊 Fig. 3: Homogenisation Hits Harder Differentiation is more frequent, but human pressures drive homogenisation much more strongly. Urban areas are hotspots, with 73.3% of urban datasets showing trait homogenisation. This intense impact leaves ecosystems fragile and less adaptable. 🌇⚠️ 120
Caio Graco-Roza @gracoroza.bsky.social · 04/12/20245/ 🧩 Fig. 2: Differentiation vs Homogenisation Differentiation is more common globally (70% of datasets), but freshwater and terrestrial ecosystems show heightened vulnerability to homogenisation—species in 40% of freshwater datasets and traits in 46.3% of terrestrial datasets. 110
Caio Graco-Roza @gracoroza.bsky.social · 04/12/20244/ 🧩 Fig. 1: Human Pressure > Climate & Geography Our first key finding: Human pressure (as in human footprint) outweighs climate and geography, being responsible for 21.5% of species turnover and 20.6% of trait turnover. Human activity reshapes biodiversity far beyond natural gradients. 🏙️🌾🌍 111
Caio Graco-Roza @gracoroza.bsky.social · 04/12/20243/ 🔬 What We Did: Analysing 160 datasets of over 13,000 local communities across 9 taxa and multiple ecosystems, we studied: Species turnover (who’s replaced) Trait turnover (what's replaced) And how human pressure stacks up against climate or geography. 110
Caio Graco-Roza @gracoroza.bsky.social · 04/12/20242/ 🌏 The Problem: Human activities—urbanisation, agriculture, and more—are reshaping biodiversity at a global scale. But HOW do these pressures affect species and the traits they carry? 🤔 Hint: It's not just about losing species; it’s about losing variety. 120
