LM scalebar = 10 µm = 20 pixels.

Observations

Contributor: Pat Kociolek - March 2011
Length Range: 57-177 µm
Width Range: 14-20 at the midsection, 20-27 at the broadest point µm
Striae in 10 µm: 29-34

Description

Valves are broadly linear with a central constriction and tapering to blunt ends. Alar canals and ribs number about 6-10 in 10 µm. Striations between the ribs are evident by fine, but not distinctly punctate striae. The raphe is contained in a canal around the margin of the valve. Undulations oriented across the face of the valve, occur the length of the valve.

Valves are broadly linear with a central constriction and tapering to blunt ends. Undulations oriented across the face of the valve, occur the length of the valve.

Compare

This species is more elongate, as compared to other species occurring in the USA flora, such as C. cochlea and C. elliptica.

EMAP Assessment

Sampling for 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). Streams and rivers in 12 western states (Arizona, California, Colorado, Idaho, Montana, Nevada, North Dakota, Oregon, South Dakota, Utah, Washington and Wyoming). Over 1200 sites on 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.

EMAP Distribution

Cymatopleura solea

Distribution

The distribution map represents the relative abundance of this Cymatopleura solea in the western EMAP study. Relative abundance is a measure of the proportion of cells of this species based on a "fixed count" of 300 total diatom cells counted and identified. Each of the western EMAP sample sites is shown, either with a black dot for sites where Cymatopleura solea was not recorded, or with a red circle indicating the relative abundance of Cymatopleura solea.

Note that the size of the proportional symbols varies between species to help show both abundant and rare species.

EMAP Response Plots

Cymatopleura solea

Responses

The 15 response plots show an environmental variable (x axis) against the relative abundance (y axis) of Cymatopleura solea from all the stream reaches where it was present. Note that the relative abundance scale is the same on each plot. Explanation of each environmental variable and units are as follows:

ELEVATION = stream reach elevation (meters)
STRAHLER = distribution plot of the Strahler Stream Order
SLOPE = stream reach gradient (degrees)
W1_HALL = an index that is a measure of streamside (riparian) human activity that ranges from 0 - 10, with a value of 0 indicating of minimal disturbance to a value of 10 indicating severe disturbance.
PHSTVL = pH measured in a sealed syringe sample (pH units)
log_COND = log concentration of specific conductivity (µS/cm)
log_PTL = log concentration of total phosphorus (µg/L)
log_NO3 = log concentration of nitrate (µeq/L)
log_DOC = log concentration of dissolved organic carbon (mg/L)
log_SIO2 = log concentration of silicon (mg/L)
log_NA = log concentration of sodium (µeq/L)
log_HCO3 = log concentration of the bicarbonate ion (µeq/L)
EMBED = percent of the stream substrate that is embedded by sand and fine sediment
log_TURBIDITY = log of turbidity, a measure of cloudiness of water, in nephelometric turbidity units (NTU).
DISTOT = an index of total human disturbance in the watershed that ranges from 1 - 100, with a value of 0 indicating of minimal disturbance to a value of 100 indicating severe disturbance.
