TL;DR: Roads are a widespread and increasing feature of most landscapes. as mentioned in this paper reviewed the scientific liter- ature on the ecological effects of roads and found support for the general conclusion that they are associated with negative effects on biotic integrity in both terrestrial and aquatic ecosystems.

TL;DR: In this article, the authors present a frame-work for a hierarchical classification system, entailed an organized view of spatial and temporal variation among and within stream systems, which is useful for research involving establishment of monitoring stations, determination of local impacts of land-use practices, generalization from site-specific data, and assessment of basinwide, cumulative impacts of human activities on streams and their biota.

TL;DR: In this article, the authors proposed a management belief system that relies upon natural habitat restoration and maintenance, as opposed to artificial propagation, installation of artificial instream structures (river engineering) and predator control.

TL;DR: Damage was frequent in low-gradient stream segments and widespread in streams with signs of recent watershed disturbance, high sediment loads, and unstable channels, and in regions where peak discharge ...

TL;DR: In this paper, the role of cold thermal refugia created by upwelling groundwater in mediating this effect has been hypothesized but not quantitatively described; however, they did find that rainbow trout O. mykiss abundance within 12 northeast Oregon (USA) stream reaches was inversely correlated with mean ambient maximum stream temperatures (r=−0.7, P 22°C).
