TL;DR: The first observation of Oncorhynchus gorbuscha smolts in Europe outside the Scandinavian and Kola peninsulas including other tributaries of the White and Barents Seas was reported in spring 2022 as discussed by the authors .

TL;DR: In this article, the authors proposed a three-tiered approach based on: restoration of channel hydromorphological dynamics; restoration and management of the riparian zone; and managing of activities in the wider catchment that have both point-source and diffuse impacts.

TL;DR: In this paper, the impact of fine sediment pressure on the macroinvertebrate community was assessed using the Combined Fine Sediment Index (CoFSI) at two sites on the Bovington Stream above and below a sediment trapping pond.

TL;DR: In this article , a variety of numerical stressor-specific biotic indices have been developed based on the response of biota to differences in stressors among sites, but it is not clear how variation in pressures within sites, over what time period, and in what combination has the greatest impact on different biotic groups.

TL;DR: In this paper , the authors examined whether substrate characteristics influence the use of the hyporheic zone as an invertebrate refuge during a fine sediment disturbance event and found evidence that movement pathways within subsurface sediments were still accessible and permitted bidirectional migration of individuals between the benthic and hypheic zones in the coarse and colmated sediments during fine sediment loading.
