Carte de distribution de Mesocalanus tenuicornis par zones géographiques
Espèce Mesocalanus tenuicornis - Carte de distribution 4issued from : T.S.K. Björnberg in Bol. Inst. Oceanogr., Sao Paulo, 1963, XIII (1). [p.11, Fig.1].
Probability of occurrence of Calanus ( = Mesocalanus) tenuicornis 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.

Nota: For Björnberg, this species appeared only sparingly in the samples belonging to southern waters off Brazil with larger frequency in surface subtropical and in greater numbers in deeper shelf waters. It can be classified as an eurythermic cryophile prefering the lower end of the temperature range for warm waters.
Espèce Mesocalanus tenuicornis - Carte de distribution 5issued from : G.A. Rebstock in Global change Biology, 2002, 8. [p.77, Fig.2 u].
Climatic regime shifts and decadal-scale variability in calanoid copepod populations off southern California (31°-35°N, 117°-122°W.
Cumulative sums of nonseasonal anomalies from the long-term means of copepod abundance from years 1950 to 2000.
A negative slope indicates a period of below-average anomalies; a positive slope indicates a period of above-average anomalies. Abrupt changes in slope indicate step changes.
The October 1966 cruise (prior to the increase in sampling depth), March 1976 cruise (prior to the 1976-77 climatic regime shift), and October 1988 cruise (prior to the hypothesized 1989 climatic regime shift) are marked with vertical lines.
Espèce Mesocalanus tenuicornis - Carte de distribution 6issued from : A.A. Shmeleva in Bull. Inst. Oceanogr., Monaco, 1965, 65 (n°1351). [Table 6: 1]. As Calanus tenuicornis (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.
