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.
