More Is Not Always Better: Selective Trait Filtering Governs Assembly Under Emerging Flow Intermittency

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
The study examined how increasing flow intermittency affects macroinvertebrate community organisation in newly drying headwater streams. Results showed that drying selectively filters species and trait states, with resistance‐ and resilience‐related survival strategies responding differently to increasing intermittency.
