Circle size is proportional to the absolute values of density and biomass.
Zooplankton samples and environmental data were collected at 56 oceanographic stations in Subantarctic and Antarctic waters of the Atlantic sector of the Southern Ocean (the Drake Passage and the Scotia Sea during three austral summers.
Oithona similis, together with small cyclopoids and nauplii, accounted for the largest percentage of the total number of copepods in the community and for the highest biomass value (63 % of total copepod biomass). |

Microdistribution of Oithona similis in Oshoro Bay (west Hokkaido, Japan), 28 August 1958, ascertained by pump along vertical section from station 3.
Nota: After the author, it is clear that the results obtained in the present investigations indicate non-random distribution.
The distribution patterns indicated the presence of inhomogeneous distribution with small swarms and irregular layerings.
Large-scale patchiness of plankton has previously been recorded (see Hardy & Gunther, 1935; Rae & Rees, 1947). The results of the present investigation indicate thet the large-scale patch includes small patches of different sizes in both the horizontal and vertical planes.
Simultaneous measurements of certain physical, chemical, and biological parameters (as the the quantitative and qualitative food particles, the occurrence of predators) are necessary to approach an understanding of copepod microdistribution. |

Nota: A tendency toward increasing the antennule length along the axix from cold areas with high salinity toward warmer regions with relatively low salinity is clearly noticeable. This is due to a decrease in water density, where temperature increases and salinity goes down.

Monthly mean (±SE) temperature (SST, °C), chlorophyll a concentration (Chl a, µg/l) and Oithona similis abundance (Ind./m3) measured at Plymouth (L4) and Gulf of Naples (LTER-MC) between 1988 and 2013.
Nota: For the authors, the abundance of O. similis at Plymouth was ± 10 times higher than in the Gulf of Naples, moreover this species had several peaks of abundance during the year at Plymouth but a single peak in spring in the Gulf of Naples. The two sites are characterized by similar chlorophyll a concentration, but different temperature.
The main mode of temporal variability in abundance was seasonal at both sites. The abundance was negatively correlated with sea temperature only in the Gulf of Naples, whereas it was positively correlated with Chl a at both sites. The authors conclude that the abundance of the species increases with prey availability up to 16°5 and that temperature > 20°C represents the main limiting factor for population persistence. |

Oithona similis females from the English Channel (50°15'N, 04°13'W), between July and December 2003.
Weight-specific respiration rate (µl O2 mg C-1 d-1) versus temperature (T, °C) measured at in situ temperature (black circle) or after pre-conditioning at experimental temperature (empty circle).
Note logarithmic scaling.
The respiration rate of adult female was measured over the temperature range 4 to 25°C. The respiration rate changed exponentially with the temperature (ln O2-rate = - 3.59 + 0.114 T, r2 = 0.85, p < 0.001).
Over the temperature range examined, O. similis basic metabolic cost varied from a minimum of about 1.4 % body-C/day at 4°C to a maximum of 23 % body-C/day at 25°C, corresponding to an energy demand of about 3 % and 232 £% body-C/day respectively.
The Q10 = 3.1.
The respiration rate of O. similis from the study, is about 8 times lower than that of a calanoid of equivalent body weight estimated from published empirical metabolism-temperature data. For the authors, these differences in metabolic rates may account for the year-round persistence and higher abundances of Oithona spp. over calanoid, particularly in oceanic and oligotrophic environments where food resources may be limiting for calanoid copepods. |

Nota: << The respiration rate of O. similis changed exponentially with temperature (ln O2-rate = - 3.59 + 0.114 T. Q10 = 3.1. Over the temperature range examined, O. similis basic metabolic cost varied from a minimum of about 1.4% body-C/day at 4°C to a maximum of 23% body-C/day at 25°C, corresponding to an energy demand of about 3% and 32% body-C/day respectively (i.e. assuming a respiratory quotient of 0.8 [for protein metabolism] and assimilation efficiency of 0.7 respectively (Ikeda & Motoda, 1978).
The respiration rate of O. similis in the English Channel, Station L4 (50°15'N, 04°13'W) is about 8 times lower than that of a calanoid copepod equivalent body weight estimated from publisher empirical metabolism-temperature data.
For the authors, these differences in lmetabolic rates may account for the year-round persistence and higher abundances of Oithona spp. over calanoids, particularly in oceanic and oligotrophic regions where food ressources may be limiting.
Success of Oithona spp. is its ability to feed on a wider size range and diversity of prey (see in Lampitt, 1978; Uchima, 1988; Gonzalez & Smetacek, 1994; Roff & al., 1995; Lonsdale & al., 2000) rather than to real differences in the metabolic rates between Oithona spp. and calanoids (Sabatini & Kiørboe, 1994; Nielsen & Sabatini, 1996).
The lower respiration rate may reflect different physiological, behaviourial and ecological adaptations from those of calanoids to live in the pelagial. Oithona spp. are ambush and coprophagus feeders, mostly drifting passively without generating a feeding current (Svensen & Kiørboe, 2000; Paffdenhöfer & Mazzocchi, 2002). Thus, whereas calanoids spend on average 80% of their time swimming, Oithobna spp. copepodites only move 0.9% or less of the time (Paffenhöfer, 1993; Hwang & Turner, 1995; Paffenhöfer & Mazzocchi, 2002). However, energy is expended not only in swimming speed, but also in the movement of mouth-parts. Thus, the lower metabolic rates of Oithona spp. could also be attributable to the absence of a feeding current.
Also, their smaller size, transparency and reduced motion probably make Oithona spp. less conspicuous than calanoids to both tactile and visual predators (Paffenhöfer, 1993; Atkinson & Snyder, 1997). Eiane & Ohman (2004) have shown that Oithona similis suffers lower mortality rates than Calanus finmarchicus and Pseudocalanus elongatus. >> |

The genetic and morphological differences show clearly that Oithona similis is not a truly cosmopolitan species, but a conglomerate of several cryptic species (see Wend-Heckmann, 2013). | | | | N: | 695 (??: see in remarks). | | | | Lg.: | | | (25) F: 0,95-0,75; (31) F: 1,2-1,15; (34) F: 0,93-0,9; (35) F: 1,08-0,76; (36) F: 0,92-0,8; (45) F: 0,95-0,7; M: 0,7-0,6; (59) F: 0,96-0,69; M: 0,7-0,5; (66) F: 1,05-0,71; M: 0,82-0,75; (46) F: 0,8-0,73; M: 0,61-0,59; (104) F: 0,82; (109) F: 0,8-0,72; M: 0,63-0,5; (114) F: 1,02-0,8; M: 0,7; (116) F: 0,84; M: 0,65; (133) F: 0,9-0,7; M: 0,6-0,5; (141) F: 0,9-0,7; M: 0,6-0,5; (155) F: 0,84-0,69; M: 0,65-0,6; (190) F: 0,86; M: 0,78; (208) F: 0,8-0,7; M: 0,75-0,73; (246) F: 0,81-0,76; (254) F,M: 1; (334) F: 0,95-0,7; M: 0,7-0,5; (354) F: 0,75-0,68; (373) F: 0,99-0,68; M: 0,75-0,58; (432) F: 1-0,75; (449) F: 0,96-0,73; M: 0,7-0,59; (627) F: 0,96-0,68; (649) F: 0,78; M: 0,67; (796) F: 0,86-0,69; (880) F: 0,78; M: 0,6-0,7; (991) F: 0,68-0,96; M: 0,6-0,7; (1239) F: 0,65-0,86; (1302) F: 0,430-0,533; M: 0,428-0,493; (1232) F: 0,64-1; M: 0,6-0,7; {F: 0,44-1,20; M: 0,43-0,82}
Probably F = 0,44, and male = 0,43 belonging to another species that O. similis s.s. | | | | Rem.: | épi à bathypélagique.
Sampling depth (Antarct., sub-Antarct.) : 0-1000 m.
Bien que la répartition géographique de cette espèce apparaisse cosmopolite, la liste des auteurs montre des localisations préférentielles pour les eaux froides septentrionales et antarctiques, voire à une latitude comme Taiwan (cf. Hsieh & al., 2004 (p.398, tab.1 & fig.2).
Observé dans les ballasts des navires à San Francisco.
Remarque concernant Oithona helgolandica:
La description sommaire de Oithona helgolandica est faite à partir du mâle à Helgoland, la femelle n'ayant jamais été décrite sinon par synonymie avec O. similis Claus,1866. L'opinion émise par Sars (1918, p.207) semble bien fondée. Dans ces conditions les arguments développés par Crisafi (1959) ne sont pas retenus, et cette espèce est considérée comme douteuse ou synonyme de O. nana comme l'expriment Rosendorn (1917) et Sars (1918). Nishida & al., 1977 (p.151) cosidèrent cette forme comme douteuse. Ainsi les auteurs postérieurs à Claus (1863) qui citent cette forme se réfèrent le plus souvent à Oithona similis.
Pour Wend-Heckmann (2013) un examen de cette espèce, considérée comme cosmopolite, constitue en réalité un ensemble d'espèces cryptiques. Seule une analyse génétique des formes géographiques localisées permettra de clarifier le statut taxonomique de cette espèce.
