Carte de distribution de Mecynocera clausi par zones géographiques
Espèce Mecynocera clausi - Carte de distribution 4issued from : T.S.K. Björnberg in Bol. Inst. Oceanogr., Sao Paulo, 1963, XIII (1). [p.25, Fig.11].
Probability of occurrence of Mecynocera clausi in different environments.
T: Tropical waters (above 36.00 p.1000 salinity and above 20°C temperature); SST: Surface subtropical waters (salinity around 36 p.1000 and temperature 18°C or less); DST: Deeper shelf waters (salinity between 34 and 36, temperature under 20°C p.1000); SS: Surface shelf waters (same salinity and temperature above 20°C);
C: coastal waters with low salinity and variable temperature.

In each column no shading means no probability of finding the species in the samples from this environment; horizontal shading indicates the probability of finding the sepecies in percentages less than one in samples from this environment; cross shading indicates the probability of finding it in percentages higher than one and black shading represents the probability of finding it in the largest percentages of the total number of copepods.

For Björnberg (1963, p.24) this species was present in nearly all samples of the most saline and warm waters off Brazil; it is a surface copepod, because it did not occur in the samples collected in deep layers and its environmental optimum lies in cooler temperatures between 18 and 10°C.
Espèce Mecynocera clausi - Carte de distribution 5issued from : A.A. Shmeleva in Bull. Inst. Oceanogr., Monaco, 1965, 65 (n°1351). [Table 6: 6]. Mecynocera clausi (from South Adriatic).
Dimensions, volume and Weight wet. Means for 50-60 specimens. Volume and weight calculated by geometrical method. Assumed that the specific gravity of the Copepod body is equal to 1, then the volume will correspond to the weight.
Espèce Mecynocera clausi - Carte de distribution 6Issued from : M. Madhupratap & P. Haridas in J. Plankton Res., 12 (2). [p.313, Fig.6].
Vertical distribution of calanoid copepod (mean +1 SE), abundance No/100 m3. 70- Mecynocera clausi.
Night: shaded, day: unshaded.
Samples collected from 6 stations located off Cochin (India), SE Arabian Sea, November 1983, with a Multiple Closing Plankton Net (mesh aperture 300 µm), in vertical hauls at 4 depth intervalls (0-200, 200-400, 400-600, 600-1000 m).
