Carte de distribution de Neocalanus gracilis par zones géographiques
Espèce Neocalanus gracilis - Carte de distribution 4issued from : R.J. Machida, M.U. Miya, M. Nishida & S. Nishida in Mar. Biol., 2006, 148. [p.1077, Fig.4].
Relationship between the phylogeny and distribution pattern of the Neocalanus species.
Shaded portions of the maps represent distributions based on the litterature. Clades A-E correspond to those in Fig.3, p.1075.
Espèce Neocalanus gracilis - Carte de distribution 5issued from : T.S.K. Björnberg in Bol. Inst. Oceanogr., Sao Paulo, 1963, XIII (1). [p.14, Fig.5].
Probability of occurrence of Neocalanus gracilis 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: Björnberg finds quite frequently in catches from Brazilian waters in very saline water layers (35.90 p.1000 or more) in the surface tropical and subtropical waters. It usually was caught in the upper layers during the night or in the early morning. Catches made during the day were poor in number of specimens, strongly indicating migration of the species to deep waters during the day.

Distribution of Neocalanus gracilis in the Pacific Ocean
Tows were taken from the surface to the depth indicared by open or filled circle. Contour intervals were chosen arbitrarily, based on breaks in the data abundances.
The copepodite stages III, IV, V, and adults were counts in aliquots (subsampled with a plankton splitter.The samples were taken during expeditions in May, Yune and August 1952; December-November 1953; September-November 1953; July-September 1955; August-September 1956; October-February 1957-1958; November 1960; June-August 1960; March-April 1960-1961; September 1964; January 1966 and March-May 1967. Most of the samples were taken by oblique tows to various depths (net: 500-550 µ mesh aperture, 1 m mouth diameter, with a flowmeter).

Nota: The distribution of N. gracilis is similar to N. robustior, both species being warm-water cosmopolites in the terminology of McGowan (1971), but the range of N. gracilis extends farther to the north and south, and this species is relatively more common in the western South Pacific than is N. robustior.
