TL;DR: In this article, the authors compared river, stream, ditch and pond biodiversity within an 80 km2 area of lowland British countryside and found that ponds contributed most to biodiversity, supporting considerably more species, more unique species and more scarce species than other waterbody types.

TL;DR: Four process-based principles that ensure river restoration will be guided toward sustainable actions are outlined and illustrated to help avoid common pitfalls in river restoration, such as creating habitat types that are outside of a site's natural potential.

TL;DR: In this paper, the authors identify the causal mechanisms that underpin the observed negative response exhibited by fish populations to enhanced fine sediment loads, and the variability across different fish species across different families.

TL;DR: In this article, the authors review the evidence available for deriving improved guidelines on the loading of fine sediment to rivers based on the impact on macro-invertebrates and conclude that existing water quality guidelines for sediment management are unlikely to be appropriate.
