Tolerance values for families of arthropods are presented to enable calculation of a family-level biotic index (FBI) in the field. In six streams differing in substrates and degree of organic
An Improved Biotic Index of Organic Stream Pollution
Major improvements were made in using a biotic index of the arthropod fauna to evaluate organic stream pollution, including an expansion of the scale ofolerance values to 0-10 to provide greater precision, a reevaluation of all tolerance values, and inclusion of tolerance values for many additional species.
Seasonal Correction Factors for the Biotic Index
Seasonal correction factors for the Biotic Index were developed to develop seasonal correction factors and to evaluate possible effects of current and temperature.
The Biology of Chironomus plumosus (Diptera: Chironomidae) in Lake Winnebago, Wisconsin
There are normally 2 generations a year in Lake Winnebago, with overwintering fourth-instar larvae pupate and emerge during mid-May; their progeny emerge from mid-July to early September.
Diversity and Classification of Insects and Collembola
Publisher Summary This chapter describes classification, anatomy, morphology, physiology, reproduction, life history, phylogeny, evolution, ecology, and taxonomy of orders and families in which one
Review of first-instar larvae of Colymbetini (Coleoptera: Dytiscidae), with a key to genera and phylogenetic analysis
A generic key to first-instar larvae of Colymbetini is presented, but it does not include the monobasic New World genera Bunites Spangler and Hoperius Fall, whose young larvae are unknown, and suggests that Meladema Laporte and Neoscutopterus J. Balfour-Browne together form the most derived lineage of the ColyMBetini.
