A Biotic Index for the Southeastern United States: Derivation and List of Tolerance Values, with Criteria for Assigning Water-Quality Ratings
  • D. Lenat
  • Biology
  • Journal of the North American Benthological…
  • 1 September 1993
TLDR
Tolerance values and classification criteria for a south-eastern biotic index were adjusted for both season and ecoregion, but no corrections were required for stream size. Expand
Effects of land use on water quality and aquatic biota of three North Carolina Piedmont streams
Three streams in the Piedmont ecoregion of North Carolina were studied to evaluate the effect of land use (forested, agricultural, urban) on water quality and aquatic biota. In comparison with theExpand
Taxonomy and stream ecology—The benefits of genus- and species-level identifications
  • D. Lenat, V. Resh
  • Biology
  • Journal of the North American Benthological…
  • 1 June 2001
TLDR
Naming even all the well-known groups in a single stream segment, such as identifying all the aquatic insects, can be a daunting task. Expand
Water Quality Assessment of Streams Using a Qualitative Collection Method for Benthic Macroinvertebrates
  • D. Lenat
  • Biology
  • Journal of the North American Benthological…
  • 1 September 1988
TLDR
A standardized qualitative sampling technique was developed and tested for shallow streams in North Carolina and found to be more rapid than a semi-quantitative technique (kick nets), yet produced a greater number of taxa per site. Expand
Agriculture and stream water quality: A biological evaluation of erosion control practices
Agricultural runoff affects many streams in North Carolina. However, there is is little information about either its effect on stream biota or any potential mitigation by erosion control practices.Expand
Using Mentum Deformities of Chironomus Larvae to Evaluate the Effects of Toxicity and Organic Loading in Streams
  • D. Lenat
  • Biology
  • Journal of the North American Benthological…
  • 1 September 1993
TLDR
The percentage of deformities in Chironomus menta was compared with both an independent measure of stream water quality and predictions of instream toxicity, and simple organic loading and toxic conditions caused large increases in both the number and types of deformity. Expand
Variable effects of sediment addition on stream benthos
Two upper Piedmont streams were studied to determine the effects of road construction, especially sediment inputs. Benthic macroinvertebrate data suggest that the stream community responded toExpand
Chironomid Taxa Richness: Natural Variation and Use in Pollution Assessment
  • D. Lenat
  • Biology
  • Freshwater Invertebrate Biology
  • 1 November 1983
TLDR
A comparison of SC with taxa richness for the intolerant Ephemeroptera, Plecoptera and Trichoptera showed no significant relationship, and SEPT was consistently found to decline with sediment addition, but the response of SC was flow dependent. Expand
The Mayflies (Ephemeroptera) of the Southeastern United States
ABSTRACT An annotated checklist consisting of 300 species is provided for the mayfly fauna of the southeastern United States [Alabama (139 spp.), Arkansas (118 spp.), Florida (77 spp.), Georgia (155Expand
