(Grunow) Frenguelli 1942      Category: Nitzschioid
BASIONYM: Nitzschia hungarica Grunow 1862

Tryblionella gracilis

 

Ulnaria contracta

LM scalebar = 10 µm = 40 pixels.



Observations

Contributor: Pat Kociolek - September 2011
Length Range: 35-100 µm
Width Range: 5-9 µm
Striae in 10 µm: 16-19

Description

Valves are linear and slightly concave in the middle. The apices are protracted slightly and bluntly rounded. The raphe is excentric, with fibulae numbering 8-11 in 10 µm. Striae appear costate, rather than distinctly punctate. A longitudinal fold is present and extends the length of the valve.

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.
