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.

Fish predation cues induce drifting and emergence in an experimental stream mesocosm system

open access: yesLimnology and Oceanography, Volume 70, Issue S2, Page S364-S376, December 2025.
Abstract Predator–prey interactions are important drivers of adaptation in aquatic communities, shaping the behavior of invertebrates with cascading effects on community dynamics. Behavioral responses, such as moving with the downstream current (drift) or altering the timing of emergence, are strategies that reduce the risk of predator encounters ...
