Species Calanus propinquus - Planche 31 of morphological figures

Planche 31 Issued from : C. Séret in Thesis UPMC, Paris 6. 1979 [P. Il].
Female (from off N Kerguelen Is.): 1, habitus (dorsal); 2, last thoracic segment and urosome (dorsal); 3, same (lateral); 4, P1; 5, P5.

Planche 32 Issued from : T.H.P. Harvey, M.I. Vélez & N.J. Butterfield in PNAS, 109 (5). [p.1591, Fig.2, C].
Gnathal edge of female right mandible of Calanus propinquus; arrow indicates dorsal seta. (Image courtesy of Jan Michels).

Nota: The Middle/Late Cambrian copepod-type mandibles are assigned to the coêôd total-group (stem or crown) based on a combination of characters including isometric growth and a dorsal seta. The Deadwood fossils thus extend the record of copepods (broadly defined) back some 190-210 Myr from fragments extracted from a Pennsylvanian (± 303 Ma) bitumen clast (see P.A. Selden & al., 2010); other pre-Holocene records are resticted to the Miocene and Cretaceous (Huys & Boxshall, 1991).

Hydrological characteristics at the transect from Adelaide Island (Antarctic Peninsula) to the Balleny Island along 67°S during the period from February 23 to March 30, 1992.
Over the greater part of the transect, the vertical temperature distribution was typical of the summer season.
The area studied was located entirely within the waters of the Antarctic vertical structure and covered four segments: The low-latitude ACPC waters (stations 694-733), the high-latitude ACC waters (stations 775, 791 and 793), the mixed waters of both types within the Ross Sea (stations 746-771 and 788), and the shelf waters represented by only a single station on its slope (station 779).
The boundary between the low-latitude and mixed waters of the high latitude modification runs along the pronounced secondary frontal zone in the area of station 739, whereas that between the mixed and properly high-latitude water modifications runs near station 778 (see in Maslennikov, 1992).

Carte 26 Issued from : D.W. Pond in J. Plankton Res., 2012, 34 (6). [p.447, Fig.3 b]
Female Calanus propinquus oil sac containing triacylglycerols. No image of a stage CV is available, but note that these often contain amounts of lipid in their oil sac that are comparable to CV Calanoides acutus.

Nota: The solid-liquid phase transitions of lipids are a factor regulating the buoancy of the copepods. These phase transitions are controlled in relation to the physical environment, through the selective accumulation of specific lipids with optimum levels of unsaturation. The necessity to control buoyancy and maintain an optimum depth is a fundamental evolutionary force, driving anatomical, biochemical and behavioural adaptations within the aquatic realm. It is hypothesized that each species adjusts the amount, composition and anatomical location of lipids, to maximize fitness according to the preferred habitat and life history traits

Remarques

Epipélagique, parfois plus profonde.
Sampling depth (Antarct., sub-Antarct.) : 0-1000 m.
Confondu parfois avec Calanus simillimus, mais de taille plus grande.
Les localisations tropicales ou subtropicales fournies par Wilson (1942 a, p.173) semblent douteuses et ne sont pas reportées dans la matrice, de même que la signalisation en Méditerranée (Malte) par Thompson (1888 d (p.139), bien que deux espèces (Ctenocalanus citer et Spinocalanus terranovae) connues seulement en Antarctique viennent récemment d'y être observées (off Malte SE, bassin Levantin NE);
Ramirez (1966) indique des tailles plus conformes à celles de C. simillimus.
