Caught Between Macrophytes and Human Impact: Zooplankton Facing Multiple Stressors in Tropical Waters

Austral Ecology, Volume 51, Issue 9, September 2026.
ABSTRACT Tropical freshwater systems host diverse and functionally important zooplankton communities that are increasingly threatened by multiple stressors. Here, we assessed how land‐use disturbance, local environmental conditions and macrophyte structure influence zooplankton richness, abundance and composition in Amazonian ponds and streams.
