Espèce Paracalanus parvus - Planche 2 de figures morphologiquesissued from : Giesecke & Gonzalez in Rev. Chil. Hist. Nat., 2004, 77. [p.610, Fig. 2 B]. Schematic drawing of the cutting edge of the lright mandible blade of Paracalanus parvus from Mejillones Bay, Chile .
Mean (SD: standard deviation in parenthesis) Itoh's edge index: 254 (29), n = 15 specimens.
V1 denote the location of the ventral-most tooth.
Scale bar = 0.010 mm.
The low edge indice (\"Type I\") suggest that this species is predominantly herbivorous, characterized by a relative thick and flat mandible. This mandibular structure is used to crush diatom frustules, the principal diet.The species might have evolved this type of strategy due to the large thick blunt ventralmost tooth, which could be used to fracture the diatoms (V1 arrow in figure). Once a part of the diatom frustule is cracked, it should be easy to continue breaking it with the help of the nine tiny bicuspid teeth. The large size mandible relative to the body size (width as % of the cephalothorax length = 9.5) indicates that this species is capable of handling larger sized particles, allowing it to feed upon a large size spectrum of diatoms.
The shape of mandibles differs slightly from observations made by Schnack (1982) in Kiel Bay (Germany). These morphological differences are due to different feeding modes or food (type and size) availability between Kiel Bay and mejillones Bay.

Espèce Paracalanus parvus - Planche 36 de figures morphologiquesIssued from : S. Nishida in Mar. Biol., 1989, 101. [p.174, fig.1 and p.175, fig.2];
Paracalanus parvus male (from Sagami Bay): lateral view of prosome showing cephalic dorsal hump (CDH) and measurements taken. d: distance between anterior margin of prosome and CDH; HL: length of CDH.
(upper figure): Cephalic dorsal hump (CDH), anterior side to the left. AnP: anterior porez; ApP: apical pore; DP: dorsal plate; TC: area of thin cuticle.

For Nishida (1989, p.183) the presence of CDH may partly answer how do the males of those copepods that have little or no modification of their appendages, capture and fertilize females. CDH may function as a short distance receptor to tdentify a conspecificd mate in the early stage of a copulatory process, thus saving energy for appropriate mating; clasping female and spermatophore transfer could be mediated with little-modified P5. It seems that spermatophore transfer itself can be attained in the absence of a highly prehensile P5. This has been achieved in pelagic cyclopoids in which P5 are much reduced into a minute segment with a few setae; the male clasps female with A1 and attaches spermatophore directly to female genital openings (see Hill & Coker, 1930; Uchima, 1998).
The mate-recognition system presumed above may partly explain the proliferation of these copepods.

Seasonal oscillatio,s in adult (continuous line) and juvenile (dashed line) populations sampled from January 1986 to December 1988 at fixed station (upper graph) and corresponding percentage infection rates for adult females and juveniles parasitized by Syndinium sp. (lower graph).

Specimens infested with Syndinium were markedly seasonal in their occurrence, with highest infection rates coinciding with periods of maximum host abundances. They also showed striking year-to-year fluctuations.
Juveniles were as heavily parasitized as adults, with infection rates of up to 12 % i September 1986. Maximum infection rates for adult females were ± 13 % in September 1988. By contrast, parasitized specimens of the genera Clausocalanus and calocalanus were extremely rare (< 0.1 %).
The dinoflagellate Blastodinium was occasionally observed in females and juveniles.

Nota: The in situ rate of egg production is significantly correlated with chlorophyll a (positive), female length (positive), and temperature (negative). Significant correlations also exist between female length and chlorophyll a (positive) and temperature (negative).
A stepwise multiple linear regression was performed to separate the effects of food, temperature, and female size on the in situ rate of egg production (seestatistical package in Nie & al., 1970).
The conclusion for the author is that variation in the rate of egg production of adult was significantly related to variation in the concentration of chlorophyll a ; variation in female size wqs significantly related to variation in the concentration of chlorophyll a and in temperature; that phytoplankton > 5µ best characterized the food used by P. parvus for the production of eggs; and finally, that an onshore-offshore gradient in food limitation of egg production by P. parvus existed, on average, during 1974-1978 in the sea off southern California.

Distribution of hydrological factors and abundance of Paracalanus parvus in Oshoro Bay (west Hokkaido, Japan), 30 August 1958, along vertical section from stations 1 to 5 (distance 650 m).

Nota: The plankton samples were collected by means of a plankton pump during the morning hours at the same time as the hydrological observations. Copepodids and adults were counted ans expressed as number of individuals per 20 l.
The distribution of copepods in a limited area seems to be related to the pattern of oceanographic conditions to some extent, but a pattern of contagious distribution is also apparent. See Barnes & Marshall (1951) ; Cassie (1959) ; Boyd (1973).

Microdistribution of Paracalanus parvus 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.

Ten-year variation in the monthly distribution of (a) water temperature (°C), (b) salinity, (c) Chl.a (log µg /L and (d) Paracalanus parvus abundance (log10 inds/m3) in Jangmok Bay (34°59'38''N, 128°40'29''E), southern coast of Korea.

Nota: The water temperature in the northern East China Sea region has been increasing steadily since the 1980s at a rate of 0.024°C per year, with the February 18°C isopleths moving nortward. Following yjis sea water temperature rise, mesozooplankton biomass and copepod concentrations have increased in all three seas surrounding the Korean Peninsula, although the reason for this remains unresolved. Seasonal changes in copepod abundance suggest that warming coastel waters are likely to result in increased populations of this species, especially winter populations.

Cleaning of the antennula by Paracalanus parvus.

Nota: Two types of cleaning were observede: cleaning of the antennula (A1), and cleaning of the carapace;
Cleaning of A1 was observed frequently, during cleaning, the copepod folded the A1 along and beneath the side of the body. The Mxp were moved as far fordward as possible outside other appendages and grabbed the A1. The mxp slid along the A1 (cleaning it), and at the same time the swimming legs moved backware along the A1. At the extreme backward position of the Mxp, the A1 began to pull forwarde under' the Pxp. The entire procedure lasted 215 ± 68 ms (Table 2).
The cleaning of the carapace was performed by the antennules folding back and up over the carapace all the way to the front. The antennules were then moved over the entire carapace backward over the tail while the swimming legs were pointing straight down. After leaving the tip of the telson, the bent antennules unfolded and returned to their straight posture. One observation of this cleaning was recorded and it lasted 227 ms (Table 2).

Certaines confusions sont possibles avec P. indicus et P. quasimodo (Cf. Hiromi, 1987; Kang, 1996), d’où certaines identifications peu sûres.
Corral Estrada (1970, Pl.13) représente une P4 plus proche de la P3 de P. indicus que deP. parvus (voir la présence de petites épines sur le bord distal externe de Exo 3 ).
