I am an ecologist starting a research group at the Lammi Biological Station (University of Helsinki). In my free time, I enjoy playing music and going to the gym. I have 🐈 🐈⬛ and I’m proudly Brazilian—wholeheartedly!
This 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…

Human pressure homogenises species and traits globally
Human pressures, particularly urbanisation and agricultural expansion, profoundly affect biodiversity by reshaping species and functional trait distributions, with critical consequences for ecosystem ...

To truly understand biodiversity loss, we need global collaboration, long-term monitoring, and policy changes that integrate functional diversity into urban planning and conservation.

9/ 💡 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 🌾.

7/ 🔄 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.

6/ 📊 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. 🌇⚠️

5/ 🧩 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.

4/ 🧩 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. 🏙️🌾🌍

3/ 🔬 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.

2/ 🌏 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.
