A Biotic Index for the Southeastern United States: Derivation and List of Tolerance Values, with Criteria for Assigning Water-Quality Ratings

Lenat, David R.·1993·Journal of the North American Benthological Society

Abstract

North Carolina's Division of Environmental Management has a large number of semiquantitative stream macroinvertebrate collections that have been assigned water-quality ratings. These semiquantitative data use abundance values of Rare = 1 Common = 3, and Abundant = 10, allowing the calculation of mean abundance (range = 0-10) for each taxon across five water-quality classes. This information was used to derive tolerance values and classification criteria for a south-eastern biotic index Classification criteria were adjusted for both season and ecoregion, but no corrections were required for stream size. Tolerance values are listed for >500 North Carolina taxa, and are compared with a similar Wisconsin data base.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
