Valves are circular with a central area spanning 1/3-2/3 of the valve face, surrounded by alveolate striae of varying length. The central area is ornate with orbiculi depressi and complementary elevated papillae, each occurring 2-6 per valve. The central area is often smooth, but it can be colliculate. Alveolate striae open externally via small areolae arranged in multiseriate rows. The rows comprise 1-2 radial striae of small areolae between 2 striae composed of larger areolae. Alveolae open internally though a large circular to oval foramen at the valve face/mantle junction. The number of fascicles per valve is 35-75, with a relation to valve size. Fascicle count is related to valve diameter (total fascicle count = 2.94 * (diameter) + 27.1). For example: (diameter, total fascicles); 15,68; 6.3,42; 3.7,35. Fascicles are separated internally by costae that occasionally branch with new rows of fascicles between the branches. One to 3 central fultoportulae occur near the orbicular depressions, with simple round external openings. Marginal fultoportulae occur every 4–5 costae. A single rimoportula occurs on a costae. A ring of spinules is present along the valve face/mantle junction and may have additional small conic spines scattered beneath.

Lindavia ocellata is part of a species complex comprising L. polymorpha, L. rossii, L. kuetzingiana, and their allies (Håkansson 2002). These species are often sympatric and may have no apparent morphological differences (Knie & Hübener 2007), therefore they may be indistinguishable in LM. The species share similar ornamentation in the central area. Traditionally, L. ocellata is thought to have only three orbiculi depressi and papillae, however several studies have shown the number of orbiculi depressi and papillae to be 2 to 6, the central area to vary from smooth to colliculate and a variable relative diameter of the central area (Kiss et al. 1999, Dudela 2016). Using combinations of the number of orbiculi depressi, central area size, and central area shape, Cvetkoska et al. (2012) distinguished 22 morphotypes of L. ocellata from a sediment core of Lake Ochrid, Macedonia. The range of valve sizes is high in L. ocellata. Edlund et al. (2003) observed valves from 2.5 to 43 µm diameter and a wide and multimodal range of initial valve size (9 to 43 µm) within a single L. ocellata population (Lake Hövsgöl, Mongolia), extending the known size range of L. ocellata. Genkal and Popovskaya (2008) similarly found different sized subpopulations of L. ocellata in the same lake.


Lindavia ocellata, reported as Cyclotella ocellata, has moderate chloride and total phosphorus optima in the Laurentian Great Lakes (Reavie and Kireta 2015). It has been reported as rare in epilithic and planktonic samples of the St. Lawrence River (Reavie and Smol 1998), lakes of Labrador and Québec (Fallu et al. 2000) and low alkalinity lakes in the northeastern United States (Camburn and Charles 2000). Lindavia ocellata occurs across a range of lake types, from deep to shallow lakes, under ultraoligotrophic (Stoermer and Yang 1969) to mesotrophic conditions (Wunsam et al. 2012).

Pérez-Martínez et al. (1992) found that auxosporulation could be induced with phosphorus additions, and they suggested that L. ocellata auxosporulation may be a resting stage to enable a population to persist during adverse conditions.

The 15 response plots show an environmental variable (x axis) against the relative abundance (y axis) of Lindavia ocellata 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.
