What is it about?
This study explores how different aquatic insect and invertebrate species co-occur and interact in rivers and lakes of the tropical Andes in Ecuador. Using advanced network analysis and large ecological datasets, the research identifies which species are commonly found together, how they form groups, and the roles that different species play within their communities. The work compares community structures in both flowing rivers and still lakes, highlighting key species and the balance between cooperative and competitive relationships.

Why is it important?
Understanding how aquatic macroinvertebrate communities are structured is crucial for monitoring ecosystem health, especially in the under-studied and rapidly changing high-mountain environments of the tropical Andes. This research provides new insights into the ecological processes that shape these communities, identifies key species for conservation, and demonstrates how network analysis can serve as an early-warning tool for environmental disturbances. The findings can support better management and protection of vital freshwater resources in a region facing strong anthropogenic pressures.
Perspectives
It was inspiring to work with a diverse team across continents to shed light on the hidden organisation of Andean aquatic ecosystems. I hope this research sparks further ecological studies in tropical mountain regions and encourages the use of network approaches for conservation planning and freshwater management in data-poor areas.
