Observations

Contributor: Pat Kociolek - September 2011
Length Range: 8-20 µm
Width Range: 3-4 µm
Striae in 10 µm: 22-27

Description

Valves are linear to linear-lanceolate, with parallel margins. The distal valve tapers abruptly to form slightly protracted to rounded apices. Fibulae are distinct, numbering 11-13 in 10 µm. Striae are parallel and finely punctate.

Autecology Discussion

EMAP Assessment

The Environmental Protection Agency (EPA) western Environmental Monitoring and Assessment Program (EMAP) study was completed during the years 2000-2004 (see citations at bottom of this page). Over 1200 streams and rivers in 12 western states (Arizona, California, Colorado, Idaho, Montana, Nevada, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming) were selected for sampling based on a stratified randomized design. This type of design insures that ecological resources are sampled in proportion to their actual geographical presence. Stratified randomized design also allows for estimates of stream length with a known confidence in several “condition classes” (good or least-disturbed, intermediately-disturbed, and poor or most-disturbed) for biotic condition, chemistry and habitat.
