We investigated whether fish assemblage structure in southern Appalachian streams differed with historical and contemporary forest cover. We compared fish assemblages in 2(nd)-4(th) order streams draining watersheds that had increased forest cover between 1950 and 1993 (i.e., reforesting watersheds). We sampled fish in 50 m reaches during August 2001 and calculated catch-per-unit-effort (CPUE) ...

Anal papillae of caddisflies are peripheral organs responsible for osmoregulation and detoxification. Investigation morphological abnormalities in the anal Hydropsyche angustipennis enriched with using SEM-EDX analysis (scanning electron microscopy-energy dispersive X-ray analysis), was used to assess heavy metal pollution levels urban streams receiving surface runoff. Heavy ions not previously...

Running with distributed generation, configuration of distribution network will be changed, that influences strength, flowing direction and duration of fault current. It analysed influence on current protection in main feeder, recloser and conventional branch line protection through the calculation formula of fault current before and after distributed generation synchronization development. In ...

Torrenticolid mites is a distinctive and common component in running water the Palaearctic, often dominate fast flowing streams mountainous areas. The present study based on material collected 2021 Bhutan. In total 17 species of two torrenticolid genera Torrenticola Piersig, 1896 Neoatractides Lundblad, 1941 are reported this study. A detailed description given for each species, facilitating th...

Study area.-All the study streams are on the northern quarter of Prince of Wales Island (Figure 1) and traverse a mixture of karst and nonkarst geology. Some streams are fed directly by resurgence from limestone caves, whereas others are fed by overland flow. Hecata Limestone and Bay of Pillars are the major karst formations (Wissmar et al. 1997). Many of the streams flow along contact zones be...

The loss of snow cover and the initiation of streamflow are key triggers for both terrestrial and aquatic biota. Landscape-scale snowmelt and streamflow dynamics are difficult to estimate, however, because they integrate large spatial extents and can vary rapidly in time. Remotely sensed observations are often temporally discontinuous and point observations lack sufficient spatial density (e.g....
