Sentence examples for on stream condition from inspiring English sources

Particularly in aquatic ecology, the consideration of the accurate spatial scale in assessing the effects of landscape factors on stream condition is critical.

Our sampling encompassed 311 sites across Catalonia (NE Spain) where we characterized anthropogenic perturbation using a summary of impacts, including local data on stream condition and landscape indicators of degradation, via a principal component analysis.

In this study, we aim to demonstrate that distribution of sedimentary mouthparts (mandibles) of aquatic mayfly (Ephemeroptera) and caddisfly (Trichoptera) larvae are dependent on stream conditions and this relationship can be used in paleohydrological studies to reconstruct past changes in stream flow.

To isolate the effect of riparian hemlock forest on stream conditions, we compared hemlock-dominated watersheds with hardwood-dominated watersheds.

The variability in the results indicate that other landscape variables, such as the influence of understory Rhododendron species, may exert more control on stream conditions than canopy composition.

To assess the influence of riparian hemlock stands on stream conditions and estimate possible impacts from hemlock loss in GSMNP, we paired hardwood- and hemlock-dominated streams to examine differences in water temperature, nitrate concentrations, pH, discharge, and available photosynthetic light.

Upon on-stream conditions the PtPd/MWNT showed the lowest thioresistence, sintering and coking among the catalysts studied.

Methane conversion was investigated by mass spectrometry under time-on-stream conditions during SRM reactions at a temperature = 700 °C for 12 h at methane/steam molar ratio = 1 2 and gas hourly space velocity = 19,600 ml g−1 h−1; selectivity toward hydrogen production and CO and CO2 formation was calculated.

In a review of impervious land cover effects on streams, Schueler and Holland (1994) propose a three-level classification system for stream condition based on percent urban/impervious area; sensitive streams (0 10 % impervious), impacted streams (11 25 % impervious), and impaired streams (26 100 % impervious).

Efforts should be focused on large pure-species riparian hemlock stands that will have the greatest immediate impact to stream conditions.

Biological indicators based on fish assemblage characteristics are used to assess stream condition worldwide.
