Macroinvertebrate community assembly in pools created during peatland restoration

摘要: Many degraded ecosystems are subject to restoration attempts, providing new opportunities unravel the processes of ecological community assembly. Restoration previously drained northern peatlands, primarily promote peat and carbon accumulation, has created hundreds thousands open water pools. We assessed potential benefits this wetland for aquatic biodiversity, how communities reassemble, by comparing pool in regions UK Pennines on intact (never drained) versus restored (blocked drainage-ditches) peatland. also evaluated conceptual idea that reference terms their compositional similarity null assemblages (and thus relative importance stochastic deterministic assembly) can guide evaluations success better than analyses composition or diversity. Community data highlighted some differences macroinvertebrate pools compared undisturbed peatland pools, which could be used suggest alternative end-points were influenced processes. However, widely diversity metrics indicated no between Novel using models confirmed assembly from national species across all Stochastic elements important drivers between-pool at regional-scale but scale these effects was similar most studied. The amalgamation theory into ecosystem monitoring allows us conclude with more certainty been successful an perspective systems. Evaluation findings those peatlands Europe North America further suggests restoring delivers significant fauna extensive habitat is largely equivalent natural More generally, we provide benchmarks planning evaluating success.
