Diversity Is Key to Ecosystem Stability, Says 20-Year Study
- Researchers at the University of Helsinki's Research Center for Ecological Change studied how biodiversity affects ecosystem stability in Finland over 20 years.
- They conducted this study using comprehensive datasets covering 900 species including birds, mammals, and phytoplankton across a 1200 km latitudinal gradient.
- The study revealed that natural communities with a wide variety of species tend to be more stable, as the varied reactions of these species to environmental shifts allow some to thrive and support the overall resilience of the community.
- Dr. Arthur Rodrigues said the study relied on nationwide datasets with hundreds of species observed over decades by professionals and volunteers, highlighting key ecological processes.
- The findings indicate that communities with low species richness and functional diversity face the greatest risk from environmental change, guiding targeted conservation to curb biodiversity loss.

Diversity is key to ecosystem stability, says 20-year study
Alongside climate change, biodiversity loss caused by human activity is one of the greatest environmental challenges of our time. A study conducted at the Research Center for Ecological Change, University of Helsinki investigated how the diversity of natural communities affects their stability amid rapid environmental change.
A Promise in a World in Crisis
“We, the peoples...” Thus begins the founding Charter of the United Nations signed in 1945. It is not a rhetorical formality, but a promise: that the international system exists not to lead us to paradise, but to save us from hell, as Dag Hammarskjöld said. In a world of climate crisis, conflicts, disinformation and growing inequalities, that promise is more urgent than ever.
