Reliable estimates of low flow and flood discharge at ungaged locations are required for evaluating stream flow alteration, designing culverts and stream crossings, and interpreting regional surveys of habitat and biotic condition. Very few stream gaging stations are located on small, remote streams, which typically have complex channel morphology. Adequate gaging is also lacking on larger streams that are remote, smaller than those typically gaged, or have channel morphology not conducive to installation of gages.

Recent studies have outlined the stepwise assembly of TCR factors CSB, CSA, UVSSA, and transcription factor IIH (TFIIH) around lesion-stalled RNAPII. However, the mechanism and factors required for the transition to downstream repair steps, including RNAPII removal to provide repair proteins access to the DNA lesion, remain unclear.

- Blackwater rivers and streams have tea-colored water due to tannins from decaying plants, and these waters typically have lower pH and oxygen levels compared to non-blackwater systems.
- While blackwaters are most common in the eastern U.S., differences in water chemistry were found between blackwater and non-blackwater sites, but these differences varied by ecoregions, making it hard to generalize nationally.
- The study suggests the need for improved understanding and management of blackwaters through better definitions, identification of stressors, and consistent assessment methods to protect their unique ecological conditions.

View Article and Find Full Text PDFStream macroinvertebrate assemblages are shaped by natural and human-related factors that operate through complex hierarchical pathways. Quantifying these relationships can provide additional insights into stream ecological assessment. We applied a structural equation modeling framework to evaluate hypothesized pathways by which watershed, riparian, and in-stream factors affect benthic macroinvertebrate condition in the Western Mountains (WMT) and Xeric (XER) ecoregions in the United States.
